RBSE Class 12 Economics Chapter 12 Multiple Choice Questions

 

Question 1. In monopoly market there are:
(a) Many sellers
(b) Few sellers
(c) One seller
(d) Two sellers
Answer: (c) One seller
In simple words: A monopoly market has only one seller who controls the entire supply of a product. This means there is no competition for that specific product.

🎯 Exam Tip: Remember that "mono" means "one," which directly relates to the single seller characteristic of a monopoly market.

 

Question 2. Who gave the concept of monopolistic competition?
(a) [Text missing from source]
Answer: (a) Edward Chamberlin
In simple words: Edward Chamberlin was the economist who first introduced the idea of monopolistic competition, which describes a market with many sellers but differentiated products.

🎯 Exam Tip: Knowing the key economists associated with different market structures helps in understanding the theoretical foundations of economics.

 

Question 3. Which one is not a characteristic of oligopoly?
(a) Interdependence
(b) Price Rigidity
(c) Indeterminate demand curve
(d) One seller
Answer: (d) One seller
In simple words: Oligopoly markets have a few sellers, not just one. The other options (interdependence, price rigidity, and an uncertain demand curve) are typical features of an oligopoly.

🎯 Exam Tip: Differentiate clearly between the number of sellers in a monopoly (one), oligopoly (few), and monopolistic competition (many but differentiated products).

 

Question 4. What type of goods are produced in monopoly market?
(a) Homogeneous
(b) Differentiated
(c) Non-Homogeneous
(d) All of these
Answer: (c) Non-Homogeneous
In simple words: In a monopoly, the product is often unique and doesn't have close substitutes, so it is not homogeneous (exactly the same) as other products.

🎯 Exam Tip: A key feature of monopoly is that the product has no close substitutes, making it distinct and non-homogeneous.

 

Question 5. Elasticity of demand for monopolists demand curve is:
(a) Less than one (e < 1)
(b) More than one (e > 1)
(c) e = 1
(d) zero
Answer: (a) Less than one (e < 1)
In simple words: For a monopoly, the demand for its product is usually inelastic, meaning that a change in price does not lead to a proportionally large change in the quantity demanded because there are no close substitutes.

🎯 Exam Tip: A monopolist faces the market demand curve, which is typically downward sloping and relatively inelastic due to the absence of close substitutes.

RBSE Class 12 Economics Chapter 12 Very Short Answer Type Questions

 

Question 1. What is monopoly?
Answer: Monopoly describes a market where there is only one producer and seller for a product. This product has no close substitutes, which means the seller faces no competition for it. Also, the concept of a separate firm and industry no longer applies, as the single firm is the entire industry.
In simple words: A monopoly is a market with only one seller of a product that has no close substitutes. The single seller acts as the entire industry.

🎯 Exam Tip: When defining monopoly, always highlight the presence of a single seller and the absence of close substitutes as the most important characteristics.

 

Question 3. What is product differentiation?
Answer: Product differentiation involves making a product distinct by changing its shape, color, form, or packaging. These differences make products somewhat similar and act as substitutes for each other, but they are not perfect substitutes. This strategy helps firms make their products stand out in the market.
In simple words: Product differentiation means making a product look or feel different (like in shape or color) from others, so it's a close but not exact replacement.

🎯 Exam Tip: Focus on how product differentiation creates perceived differences, making products unique in the eyes of consumers, even if they serve similar purposes.

 

Question 4. Differentiated products are the feature of which market?
Answer: Oligopoly.
In simple words: Differentiated products are a common feature of an oligopoly market, where a few large firms sell products that are similar but not identical.

🎯 Exam Tip: Remember that product differentiation is a key feature in both monopolistic competition and oligopoly, but not in perfect competition or pure monopoly.

 

Question 5. Write any one characteristic of oligopoly market.
Answer: One characteristic of an oligopoly market is mutual dependence among firms. Because there are only a few sellers, each firm's decisions about price or output depend on how they expect rival firms to react. This creates a complex strategic environment where firms constantly monitor each other's moves.
In simple words: In an oligopoly, firms depend on each other's actions, meaning one firm's decisions affect the others.

🎯 Exam Tip: Mutual dependence is the most defining characteristic of an oligopoly, explaining why firms in such markets engage in strategic behavior.

RBSE Class 12 Economics Chapter 12 Short Answer Type Questions

 

Question 1. Define monopolistic market.
Answer: A monopolistic market is one where a specific product has only one producer or seller, and this product does not have any close substitutes. Professor Leftwich defines pure monopoly as a market where one firm sells a product that has no available substitutes. This means the firm has significant control over its price and output.
In simple words: A monopolistic market has only one seller of a unique product with no close replacements, giving that seller a lot of market control.

🎯 Exam Tip: When defining a monopolistic market, emphasize both the single producer and the lack of close substitutes, as these are its core elements.

 

Question 2. "Real competition exists in oligopoly market.” Explain this statement.
Answer: Oligopoly is a market structure with a small number of firms producing similar or slightly differentiated products. In this market, firms closely observe and react to their rivals' policies, leading to strong competition. Since there are few producers, they are well-aware of each other's strategies and prepare solutions to counter them, resulting in fierce competition. This is why it is often said that real competition is most evident in an oligopolistic market.
In simple words: In an oligopoly, a few firms compete closely, watching and reacting to each other's moves, which leads to strong, real competition.

🎯 Exam Tip: The idea of "real competition" in oligopoly stems from the visible strategic interaction and mutual dependence among the few dominant firms.

 

Question 4. Write down any two characteristics of monopolistic competition.
Answer: The two main characteristics of monopolistic competition are:
1. In monopolistic competition, many firms exist, but no single firm dominates a large portion of the total output. Firms do not need to worry about rivals' reactions because there are many sellers, and competition happens among all of them.
2. Products made by different firms in this market have small differences, based on factors like form, color, shape, design, or packaging. This differentiation creates brand loyalty among consumers.
In simple words: Monopolistic competition has many firms, but each sells a slightly different product, creating variety and competition based on these differences.

🎯 Exam Tip: For monopolistic competition, always mention both "many sellers" and "differentiated products" as these two features define this market structure.

 

Question 5. Write down the meaning of imperfect competition.
Answer: Imperfect competition is a broad term covering market structures between perfect competition and pure monopoly. It includes real-world market situations like oligopoly, duopoly, and monopolistic competition. Professor Fairchild defined it as a market where relations between buyers and sellers are not well-organized, making it difficult for them to compare products and prices. This term describes markets that are not perfectly efficient or completely controlled by one entity.
In simple words: Imperfect competition covers market types between perfect competition and monopoly, where buyers and sellers don't have full information and products aren't always easy to compare.

🎯 Exam Tip: When explaining imperfect competition, emphasize that it encompasses most real-world markets and includes market structures like monopolistic competition and oligopoly.

RBSE Class 12 Economics Chapter 12 Essay Type Questions

 

Question 1. "Monopolistic market is an extreme situation". Discuss this statement.
Answer: A monopolistic market is indeed an extreme situation because it involves a single producer or seller of a specific product with no close substitutes. This means the monopolist faces no direct competition and has full control over the market for their product. The existence of a single producer ensures there are no rivals or competitors. The ability to control the market fundamentally depends on the firm's success in stopping any potential competitors from entering. Examples include railways having competition from roadways, or electricity departments facing alternative energy sources like solar power. Both pure monopoly and perfect competition are theoretical concepts rarely seen exactly in real life. Most real-world markets fall somewhere between these two extremes, known as imperfect competition.
In simple words: A monopolistic market is extreme because one seller fully controls a unique product with no substitutes, leading to no competition. In reality, most markets are imperfect, falling between pure monopoly and perfect competition.

🎯 Exam Tip: When discussing a monopolistic market as an "extreme situation," explain why it's extreme (single seller, no substitutes) and contrast it with real-world markets that are usually forms of imperfect competition.

 

Question 2. Discuss in detail the main characteristics of monopolistic competition.
Answer: The main features of monopolistic competition are:
(a) Existence of a Large Number of Firms: In this market, many firms operate, each having a small share of the total industry output. These firms are typically small and don't significantly influence the market. This structure is common in industries with limited economies of scale and simple production techniques.
(b) Product Differentiation: A key feature is that products from different firms, though similar, have distinct differences in color, shape, brand, quality, or packaging. These differentiated products serve as close substitutes. Examples include various brands of soaps like Pears and Dove, or pens like Reynolds and Parker, which compete by highlighting their unique features.
(c) Freedom of Entry and Exit of Firms: New firms can easily enter this market, and existing firms can leave. When current firms earn good profits, new firms are attracted, increasing production. This usually leads to prices decreasing in the long run. However, entry might involve creating new brands, which can be challenging against established ones.
(e) Non-price Competition: Firms use non-price strategies to attract customers, such as offering repair guarantees, after-sales service, or gift plans. This focus on differentiation and service helps them gain and maintain market share rather than just competing on price.
(f) Less Mobility: Unlike perfect competition, factors of production like goods and services are not fully mobile under monopolistic competition.
(g) More Elastic Demand: The demand curve for a firm in monopolistic competition is more elastic than in a pure monopoly. To sell more products, a firm must lower its price.
(h) Selling Costs: Advertising and sales promotion are significant in this market. Selling costs are expenses incurred by firms to promote their sales through advertisements, salesmanship, and other promotional activities.
(i) Imperfect Knowledge: Buyers and sellers often lack complete information about product prices. Due to product differentiation, comparing products from different companies is difficult, leading buyers to favor specific brands.
In simple words: Monopolistic competition has many firms that sell slightly different products. Firms can enter and exit easily, compete using advertising and other non-price methods, and their product demand is fairly sensitive to price changes.

🎯 Exam Tip: When describing monopolistic competition, always explain how product differentiation enables firms to have some market power despite the presence of many sellers and easy entry/exit.

 

Question 3. Write down the meaning and characteristics of oligopoly.
Answer: Oligopoly is a significant form of imperfect competition where a market has a small number of firms producing or selling a product. The term "oligopoly" refers to "competition among the few" because there are more than two but not many producers. There is no clear line between "few" and "many," but the key is that firms are limited enough to be interdependent. William Fellnser called it "competition among the few."
The characteristics of oligopoly are:
(a) Monopoly Power: An oligopoly firm has some monopoly power, as it's not the only firm but still influences the industry through its market conditions and business practices. It has a monopolistic character because of product differentiation and brand loyalty.
(b) Interdependence: Firms cannot make price and output decisions independently. Since there are few firms, each must consider how rivals will react. A decision by one firm greatly impacts the decisions of others.
(c) Indeterminate Demand Curve: Because firms are interdependent, their demand curve is uncertain. If one firm lowers its price, rivals might do the same, making it hard to predict the demand for its product. This constant reaction among rivals makes the demand curve unpredictable.
(d) Role of Selling Costs: Advertising and sales promotion play a major role in oligopolistic markets. Firms spend a lot on these to maintain and increase their market share, even more than in other market systems.
(e) Conflicting Attitudes of Firms: Firms often face a dilemma: they can either cooperate to maximize joint profits or compete fiercely, sometimes leading to cut-throat competition. This results in conflicting attitudes, alternating between cooperation and conflict.
(f) Lack of Uniformity: There is no standard size for firms in an oligopoly. Some may be small, while others are very large.
(g) Price Rigidity: Prices tend to be inflexible under oligopoly, especially with product differentiation. If a firm cuts prices, rivals might follow, so firms often avoid price wars.
In simple words: Oligopoly means a market with a few big sellers who are very interdependent, meaning each firm's decisions affect the others. They have some monopoly power, face uncertain demand, spend a lot on advertising, and often have rigid prices.

🎯 Exam Tip: When describing oligopoly, emphasize interdependence and price rigidity, as these characteristics are unique and crucial for understanding firm behavior in such markets.

 

Question 1. Which of the following is not a characteristic of monopolistic competition?
(a) Ease of entry into the industry.
(b) Product differentiation.
(c) A relatively large number of sellers.
(d) A homogenous product.
Answer: (d) A homogenous product
In simple words: Monopolistic competition is known for differentiated products, not homogeneous (identical) ones. The other options are true characteristics.

🎯 Exam Tip: Differentiate between perfect competition (homogeneous products) and monopolistic competition (differentiated products).

 

Question 2. All of the following are characteristics of a monopoly except :
(a) There is a single firm.
(b) The firm is a price taker.
(c) The firm produces a unique product.
(d) The existence of some advertising.
Answer: (b) The firm is a price taker
In simple words: A monopolist is a price maker, not a price taker, because it controls the entire market supply and can set its prices.

🎯 Exam Tip: Remember that a price taker operates in perfect competition, while a price maker (or setter) has market power, as in a monopoly.

 

Question 3. Oligopolistic industries are characterized by:
(a) A few dominant firms and substantial barriers to entry.
(b) A few large firms and no entry barriers.
(c) A large number of small firms and no entry barriers.
(d) One dominant firm and no entry barriers.
Answer: (a) A few dominant firms and substantial barriers to entry
In simple words: Oligopolies are markets dominated by a few large companies that also have significant hurdles for new firms to enter.

🎯 Exam Tip: Barriers to entry are crucial in maintaining the "few firms" structure of an oligopoly, preventing new competitors from diluting market control.

 

Question 4. Monopolistic competition differs from perfect competition primarily because:
(a) In monopolistic competition, firms can differentiate their products.
(b) In perfect competition, firms can differentiate their products.
(c) In monopolistic competition, entry into the industry is blocked.
(d) In monopolistic competition, there are relatively few barriers to entry.
Answer: (a) In monopolistic competition, firms can differentiate their products
In simple words: The main difference is that firms in monopolistic competition make their products unique, while in perfect competition, products are identical.

🎯 Exam Tip: Product differentiation is the defining factor that gives firms some market power in monopolistic competition, unlike perfect competition.

 

Question 6. A monopolist is able to maximize his profits when :
(a) His output is maximum.
(b) He charges a high price.
(c) His average cost is minimum.
(d) His marginal cost is equal to marginal revenue.
Answer: (d) His marginal cost is equal to marginal revenue
In simple words: A monopolist maximizes profits by producing at the point where the extra cost of making one more unit is equal to the extra revenue gained from selling it.

🎯 Exam Tip: The profit-maximization rule \( MR = MC \) applies to all firms, including monopolies, to determine the optimal output level.

 

Question 7. In which form of the market structure is the degree of control over the price of its product by a firm very large?
(a) Monopoly
(b) Imperfect Competition
(c) Oligopoly
(d) Perfect Competition
Answer: (a) Monopoly
In simple words: A monopoly firm has the most control over its product's price because it is the only seller and has no competition.

🎯 Exam Tip: The degree of price control is highest in a monopoly and lowest in perfect competition, varying in between for other market structures.

 

Question 8. Under which of the following forms of market structure does a firm has no control over the price of its product?
(a) Monopoly
(b) Monopolistic competition
(c) Oligopoly
(d) Perfect competition
Answer: (d) Perfect competition
In simple words: In perfect competition, firms must accept the market price, as they are too small to influence it.

🎯 Exam Tip: Firms in perfect competition are "price takers" because they sell identical products and have many competitors, so they cannot set their own prices.

 

Question 10. One characteristic not typical of oligopolistic industry is :
(a) Horizontal demand curve.
(b) Too much importance to non-price competition.
(c) Price leadership.
(d) A small number of firms in the industry.
Answer: (a) Horizontal demand curve
In simple words: An oligopoly does not have a horizontal demand curve; that's a feature of perfect competition. Oligopolies typically face a downward-sloping or kinked demand curve.

🎯 Exam Tip: A horizontal demand curve implies perfect elasticity, meaning a firm can sell any quantity at the market price, which is only true for perfect competition.

 

Question 11. The structure of the toothpaste industry in India is best described as :
(a) Perfectly Competitive
(b) Monopolistic
(c) Monopolistically competitive
(d) Oligopolistic
Answer: (c) Monopolistically competitive
In simple words: The toothpaste industry has many brands, each slightly different, and many sellers, fitting the description of monopolistic competition.

🎯 Exam Tip: Real-world industries with many brands offering similar but differentiated products (like toothpaste, soaps, clothes) are classic examples of monopolistic competition.

 

Question 12. The structure of the cold drink industry in India is best described as :
(a) Perfectly competitive
(b) Monopolistic
(c) Monopolistically competitive market earn normal profits
(d) Oligopolistic
Answer: (d) Oligopolistic
In simple words: The cold drink industry in India is dominated by a few large players, which makes it an oligopoly market structure.

🎯 Exam Tip: Industries dominated by a few powerful brands (like soft drinks or automobiles) are prime examples of oligopolies, where firms are highly interdependent.

 

Question 13. Which of the following statements is incorrect?
(a) [Text missing from source]
Answer: (a) A purely competitive firm's demand curve is perfectly elastic.
In simple words: The statement that a purely competitive firm's demand curve is perfectly elastic (horizontal) is a correct characteristic, meaning this option would likely contain an incorrect statement in the complete question.

🎯 Exam Tip: For "incorrect statement" questions, always identify the true statements first to easily spot the false one.

 

Question 14. The market for hand tools (such as hammers and screwdrivers) is dominated by Draper, Stanley and Craftsman. This market is best described as :
(a) Monopolistically competitive
(b) A monopoly
(c) An oligopoly
(d) Perfectly competitive
Answer: (c) An oligopoly
In simple words: When a market is controlled by just a few major companies, like Draper, Stanley, and Craftsman for hand tools, it is called an oligopoly.

🎯 Exam Tip: Recognize that "dominated by" typically signals an oligopolistic market structure due to the presence of a few large firms.

 

Question 15. A market structure in which many firms sell products that are similar but, not identical is known as :
(a) Monopolistic competition
(b) Monopoly
(c) Perfect competition
(d) Oligopoly
Answer: (a) Monopolistic competition
In simple words: This market type has many firms selling products that are similar but have slight differences, like different brands of coffee.

🎯 Exam Tip: The combination of "many firms" and "differentiated but similar products" is the hallmark definition of monopolistic competition.

 

Question 16. When an oligopolist individually chooses its level of production to maximize its profits, it charges a price that is:
(a) More than the price charged by either monopoly or a competitive market.
(b) Less than the price charged by either monopoly or a competitive market.
(c) More than the price charged by a monopoly and less than the price charged by a competitive market.
(d) Less than the price charged by a monopoly and more than the price charged by a competitive market.
Answer: (d) Less than the price charged by a monopoly and more than the price charged by a competitive market
In simple words: An oligopolist's profit-maximizing price is typically higher than in perfect competition but lower than in a pure monopoly because of limited competition.

🎯 Exam Tip: Understand the hierarchy of pricing power: monopoly has the most, followed by oligopoly, then monopolistic competition, and perfect competition has none.

 

Question 17. Which of the following is not a characteristic of a monopolistically competitive market?
(a) Free entry and exit
(b) [Text missing from source]
Answer: (b) Price-taking behavior
In simple words: Monopolistically competitive firms are not price-takers; they have some control over their prices due to product differentiation. Free entry and exit is a characteristic.

🎯 Exam Tip: Monopolistic competition allows firms to set their prices to some extent, unlike the pure price-taking behavior in perfect competition.

RBSE Class 12 Economics Chapter 12 Very Short Answer Type Questions

 

Question 1. Define Monopoly.
Answer: Monopoly is a market structure that represents an extreme situation where a single producer and seller exists for a product that has no close substitutes in the market. In such a market, the concept of a separate firm and industry no longer applies, as the sole firm embodies the entire industry.
In simple words: Monopoly is a market where one seller offers a unique product with no substitutes.

🎯 Exam Tip: When defining monopoly, always include the core elements: single seller and lack of close substitutes.

 

Question 2. What are the two features of monopoly?
Answer: The two main features of monopoly are:
1. Single Seller: In a monopoly, there is only one producer of the product. This means the monopolist controls the entire supply.
2. No Substitute for the Commodity: All units of the product are identical, and there are no close substitutes available. This uniqueness gives the monopolist significant market power.
In simple words: The two features of monopoly are having only one seller and selling a product with no close replacements.

🎯 Exam Tip: These two features are fundamental to understanding how a monopolist can influence market price and quantity.

 

Question 3. Under what conditions can a monopoly firm attain equilibrium?
Answer: A monopoly firm can attain equilibrium under conditions where:
1. The monopolist is the sole seller of the product. This means the firm controls the entire market supply.
2. In a monopoly, the firm and the industry are considered the same entity. This is because there are no other producers to form a separate industry, allowing the firm to set prices and production levels without direct competition.
In simple words: A monopoly reaches balance when it is the only seller of a product, and the company itself is seen as the whole industry.

🎯 Exam Tip: Equilibrium for a monopolist is achieved at the output level where marginal revenue equals marginal cost, as is true for all profit-maximizing firms.

 

Question 4. What is discriminating monopoly?
Answer: A discriminating monopoly occurs when a company with monopoly power charges different prices for the same product in different markets, based on each market's characteristics. For this to be profitable, the monopolist must be able to identify the demand sources in each market and set prices accordingly. This strategy aims to maximize the firm's overall profitability by extracting different consumer surpluses from different groups.
In simple words: A discriminating monopoly sells the same product at different prices in different markets to earn more profit.

🎯 Exam Tip: Key conditions for price discrimination are the ability to segment markets, prevent resale, and have differing price elasticities of demand in those segments.

 

Question 5. [Question text missing: W or a discriminating monopoly?]
Answer: [Answer text missing from source: Loading [MathJax]/extensions/MathZoom.js]
In simple words: [Explanation missing]

🎯 Exam Tip: [Tip missing]

 

Question 6. When is price discrimination profitable?
Answer: Price discrimination is profitable only if the price elasticity of demand differs between the various markets. If demand is more elastic in one market and less elastic in another, the monopolist can charge a higher price where demand is less elastic and a lower price where demand is more elastic, thereby maximizing overall profit. Also, there must be no chance for buyers to move from one market to another and resell the product.
In simple words: Price discrimination works best when customers in different markets react differently to price changes, allowing the seller to charge more to those less sensitive to price.

🎯 Exam Tip: Remember that differing price elasticities of demand across markets is a fundamental condition for successful and profitable price discrimination.

 

Question 7. What is dumping?
Answer: Dumping occurs when a producer sells a product in a foreign country at a price lower than the price charged in their domestic market, after accounting for transportation costs and tariffs. This practice is often used to gain market share in the foreign country or to offload surplus production.
In simple words: Dumping is when a country sells goods in another country at a cheaper price than it sells them at home.

🎯 Exam Tip: Dumping is a form of international price discrimination, where a producer exploits different demand elasticities in domestic and foreign markets.

 

Question 8. What are the methods of control of monopoly?
Answer: The two main methods to control monopoly are:
I. Indirect Method
(a) Anti-monopoly legislation: Laws are put in place to prevent monopolies from forming or to regulate existing ones, ensuring fair competition.
(b) Maintenance of Fair Competition: Policies encourage competition and prevent unfair business practices by monopolistic firms.
II. Direct Method
(a) Purchaser's Association: Consumer groups can exert pressure and negotiate with monopolists.
(b) Publicity: Public awareness campaigns can highlight monopolistic abuses, influencing consumer behavior and policy.
(c) Direct price regulation: The government directly sets or controls the prices a monopolist can charge to prevent exploitation.
In simple words: Monopolies can be controlled indirectly through laws promoting competition or directly by government price limits and consumer groups.

🎯 Exam Tip: Be sure to distinguish between direct methods (like price control) and indirect methods (like legislation) when discussing monopoly regulation.

 

Question 10. Define monopoly according to Prof. Thomas.
Answer: According to Prof. Thomas, "Broadly, the term is used to cover any effective price control whether supply or demand of services or of goods. It is used to mean a combination of manufacturers or merchants to control the supply price of commodities or services." This definition emphasizes that monopoly is about controlling prices through supply or demand mechanisms.
In simple words: Professor Thomas defined monopoly as having strong control over the price of goods or services, usually by a group of producers or sellers working together.

🎯 Exam Tip: When quoting a definition, ensure accuracy of the quote and attribute it correctly to the economist.

 

Question 11. Define monopoly according to Lerner.
Answer: According to Lerner, "A monopolist is a seller who is confronted with a falling demand curve for his product." This definition highlights that a monopolist faces the entire market demand, which typically slopes downward, meaning to sell more, they must lower their price.
In simple words: Lerner described a monopolist as a seller who sees the demand for their product go down if they raise the price.

🎯 Exam Tip: Lerner's definition connects the monopolist's market power to the downward-sloping demand curve they face, unlike firms in perfect competition.

 

Question 12. Define monopoly according to K.E. Boulding.
Answer: According to K.E. Boulding, "A pure monopolist is a firm producing product which has no effective substitutes among the products of other firms, effective in the sense that even though the monopolist may be making abnormal profits, other firms cannot encroach on these profits by producing substitute commodities which might attract purchasers away from the product of the monopolist." Boulding stresses the absence of *effective* substitutes as the core of pure monopoly, preventing new firms from eroding profits.
In simple words: K.E. Boulding defined a pure monopolist as a company that makes a product with no good replacements, so other firms can't easily steal its profits.

🎯 Exam Tip: Boulding's definition emphasizes the long-term sustainability of monopoly profits due to the lack of effective substitutes and barriers to entry.

 

Question 13. Define monopoly according to John D.Sumur.
Answer: According to John D. Sumur, "Pure monopoly implies zero elasticity of demand in contrast to the infinite elasticity of demand which is a characteristic of pure competition." Sumur's definition points to the extreme inelasticity of demand in a pure monopoly, where changes in price have no effect on quantity demanded, as opposed to the perfectly elastic demand in pure competition.
In simple words: John D. Sumur said that pure monopoly means the demand for the product doesn't change at all when the price changes, which is the opposite of perfect competition where demand is very sensitive to price.

🎯 Exam Tip: Sumur's definition uses elasticity to clearly contrast pure monopoly with pure competition, highlighting the extreme differences in demand responsiveness.

 

Question 14. What is imperfect competition?
Answer: Imperfect competition describes a competitive market situation where many vendors exist, but they are selling differentiated or "unequal" goods. This stands in contrast to a completely competitive market scenario, where products are identical. In imperfect competition, firms have some degree of market power, allowing them to influence prices to a certain extent.
In simple words: Imperfect competition is a market where many sellers offer products that are not exactly the same, giving them some power over prices.

🎯 Exam Tip: The key idea in imperfect competition is that products are differentiated, allowing firms some influence over price, unlike in perfect competition.

 

Question 16. State a feature of monopolistic competition.
Answer: A key feature of monopolistic competition is that buyers and sellers lack perfect knowledge about the price of the product. This is because it is challenging to compare products from different firms due to product differentiation. Consumers often rely on brand loyalty or perceived differences rather than complete price transparency.
In simple words: In monopolistic competition, people don't fully know all product prices because the products are all a bit different.

🎯 Exam Tip: Imperfect knowledge in monopolistic competition contributes to firms' ability to maintain some price control and differentiation strategies.

 

Question 17. What is the concept of selling cost?
Answer: Selling costs are a significant part of the total cost in imperfect or monopolistic competition. These costs are incurred by firms to promote their sales, primarily through advertisements and salesmanship. The goal is to inform, persuade, and influence consumers to purchase their specific differentiated product over competitors'.
In simple words: Selling costs are the money spent by companies on things like advertising to help sell their products, especially when products are different from each other.

🎯 Exam Tip: Selling costs are essential in monopolistic competition to highlight product differentiation and attract customers, as opposed to perfect competition where products are identical.

 

Question 18. What do you understand by Oligopoly?
Answer: Oligopoly is a market structure where there are more than two, but not many, producers or sellers of a product. This means a few large firms dominate the market, leading to high interdependence where each firm's actions significantly affect the others. It's often called "competition among the few."
In simple words: Oligopoly is a market where a few big sellers offer a product, and each seller's decisions impact the others.

🎯 Exam Tip: The defining characteristic of oligopoly is the small number of dominant firms and their strong mutual interdependence.

 

Question 19. What is Kinked Demand curve?
Answer: The Kinked Demand curve is a model used to explain price rigidity in an oligopolistic market. It suggests that if an oligopolist raises its price, rivals will not follow, leading to a large drop in demand for the first firm's product (elastic demand). However, if the firm lowers its price, rivals will match the cut, so the firm gains only a small increase in demand (inelastic demand). This creates a "kink" in the demand curve at the current price, explaining why prices tend to be stable. Paul Sweezy first used this concept in 1934.
In simple words: A Kinked Demand curve explains why prices in an oligopoly market often stay the same; if one firm raises its price, others won't follow, but if it lowers its price, others will.

🎯 Exam Tip: The kinked demand curve helps explain why price wars are often avoided in oligopolies, leading to stable prices even without formal agreements.

 

Question 20. What is collusive oligopoly?
Answer: Collusive oligopoly is a market situation where firms in a particular industry decide to work together to maximize their joint profit as a single entity, rather than competing. They negotiate for market share and collectively set prices and output levels, essentially acting like a monopoly to avoid competition and increase overall industry profits.
In simple words: Collusive oligopoly is when a few competing firms secretly agree to work together, like setting prices or sharing the market, to earn more profit together.

🎯 Exam Tip: Collusion often involves agreements to restrict output or fix prices, effectively reducing competition and behaving like a cartel.

Question 22. Define oligopoly according to Prof. George J. Stigler.
Answer: According to Prof. George J. Stigler, "That situation in which a firm bases its market policy in part on the expected behavior of a few close rivals." This definition highlights the strategic interdependence among firms in an oligopoly, where each firm's decisions are influenced by how it anticipates competitors will react.
In simple words: Professor Stigler defined oligopoly as a market where a firm decides its plans based on how it thinks its few main competitors will act.

🎯 Exam Tip: Stigler's definition underlines the strategic nature of decision-making in an oligopoly, where anticipation of rival reactions is crucial.

 

Question 23. Define Monopolistic competition according to Leftwitch.
Answer: According to Leftwitch, "Monopolistic competition is a market situation in which there are many sellers of a particular product, but the product of each seller is in some way differentiated in the minds of consumers from the product of every other seller." This definition emphasizes both the numerous sellers and the mental differentiation of products by consumers.
In simple words: Leftwitch described monopolistic competition as a market with many sellers, but each seller's product is perceived as unique by buyers.

🎯 Exam Tip: Leftwitch's definition is key because it combines the "many sellers" aspect with the "differentiated product" element, which forms the basis of monopolistic competition.

RBSE Class 12 Economics Chapter 12 Short Answer Type Questions

 

Question 1. What are the four features of monopoly?
Answer: The four main features of monopoly are:
(a) Single Seller: In a monopoly, there is only one producer of the commodity, meaning one firm controls the entire supply.
(b) Firm is also an Industry: Since there is only one firm, the distinction between a firm and an industry does not exist. The monopoly firm itself constitutes the entire industry.
(c) No Substitute for the Commodity: All units of the commodity are identical, and there are no close substitutes available for consumers. This gives the monopolist significant market power.
(d) No Entry of new firms: There are significant restrictions or barriers that prevent other firms from entering the market. These barriers could be legal, economic, or technological.
In simple words: The four features of monopoly are: only one seller, the firm is the industry, no close substitute products, and new firms cannot enter the market.

🎯 Exam Tip: These four features collectively explain how a monopolist maintains its dominant position and market power.

 

Question 2. Explain the nature of demand and revenue curve under monopoly.
Answer: The demand curve for a monopoly firm is the same as the market demand curve. This curve slopes downward from left to right, showing that to sell more of the product, the monopolist must lower its price, and vice versa. This market demand curve also represents the monopolist's average revenue (AR) curve. As a result, the average revenue curve of a monopolist slopes downwards, indicating that a higher quantity can only be sold at a lower price.
In simple words: In a monopoly, the demand curve slopes downwards, meaning the seller must cut prices to sell more. This same curve also shows the average money earned per unit.

🎯 Exam Tip: The downward-sloping demand curve for a monopolist is a key graphical representation of its market power and its role as a price maker.

 

Question 3. The monopolist is able to gain super-normal profit in the long run. How?
Answer: A monopoly firm can consistently earn super-normal profits in the long run because entry into the industry is strictly prohibited. Unlike perfect competition, no new firms can enter the market to compete away these extra profits. When a monopolist generates significant, long-lasting profits, other producers cannot join to share in this potential. Therefore, these super-normal profits continue indefinitely. The lack of entry barriers and the absence of substitutes allow the monopolist to adjust its production capacity to meet market demand effectively.
In simple words: A monopolist can keep making extra-high profits over a long time because new companies are not allowed to enter the market and compete.

🎯 Exam Tip: The crucial factor enabling long-run super-normal profits for a monopolist is the presence of effective barriers to entry, which prevent new competition.

 

Question 4. Explain measurement of monopoly power.
Answer: Not all monopolists possess the same degree of market power; some are more powerful than others. The ability to influence price is not uniform across all cases. Monopoly power can be measured or understood through several indicators:
(a) The greater the variation between marginal cost and price, the higher the monopolist's power. This difference is often used in the Lerner Index.
(b) More powerful monopolists are typically able to achieve larger monopoly profits, indicating a stronger ability to set prices above costs.
(c) Where the demand elasticity is lower (meaning consumers are less responsive to price changes), the extent of monopoly power is greater.
(d) Monopoly power tends to be lower when the cross-elasticity of demand is high, meaning consumers can easily switch to other products if the monopolist raises prices.
In simple words: Monopoly power is measured by how much a firm can raise its price above its production cost, how much profit it makes, how little demand changes when prices change, and how hard it is for buyers to switch to other products.

🎯 Exam Tip: The Lerner Index (\( \frac{P - MC}{P} \)) is a common formal measure of monopoly power, directly linking it to the difference between price and marginal cost.

 

Question 5. When is price discrimination profitable? Why?
Answer: Price discrimination is profitable when the price elasticity of demand differs significantly across different markets at a single monopoly price. If the elasticity of demand varies (e.g., one market has inelastic demand and another has elastic demand), then the marginal revenue in one market will be greater than in the other. As a result, it becomes profitable for the seller to shift some units from the market with lower marginal revenue to the market with higher marginal revenue, charging different prices to maximize total profit. This strategy increases the seller's overall revenue.
In simple words: Price discrimination is profitable when customers in different markets react differently to price changes. This lets the seller charge higher prices where demand is less sensitive and lower prices where it's more sensitive, increasing overall profit.

🎯 Exam Tip: For price discrimination to be profitable, the monopolist must be able to segment customers based on their willingness to pay and prevent resale between markets.

 

Question 7. Write down a brief note on maintenance of Fair Competition in anti-monopoly legislation.
Answer: Anti-monopoly legislation aims to maintain fair competition by regulating the behavior of monopolists. Since a monopolist often restricts supply and charges high prices due to the absence of competitors, such laws ensure that they do not abuse their market power. If a monopolist faces the possibility of competition, they are less likely to exercise their monopoly powers freely. The government prohibits unfair trade practices used by monopolists to harm rivals, although implementing these policies can be challenging. For example, the government might regulate prices, but monopolists could offer other incentives to eliminate competitors.
In simple words: Anti-monopoly laws try to ensure fair competition by stopping monopolies from setting high prices or using unfair business tactics. These laws aim to control monopolies by making sure they don't abuse their power.

🎯 Exam Tip: Fair competition is maintained through legislation that prevents anti-competitive behaviors like predatory pricing and mergers that reduce market rivalry.

 

Question 9. Explain short run equilibrium under monopolistic competition.
Answer: In the short run, a monopolistically competitive firm reaches equilibrium at the output level where its marginal cost (MC) equals its marginal revenue (MR), and the marginal cost curve is rising at that point. However, short-run equilibrium does not mean all firms charge the same price. Prices can vary because products are differentiated, and production costs differ among firms. Large firms usually have lower average costs than small firms. Therefore, in the short run, a monopolistically competitive firm may:
(a) Earn super-normal profits, if Average Revenue (AR) is greater than Average Cost (AC)
(b) Earn normal profits, if AR is equal to AC
(c) Incur losses, if AR is less than AC
In simple words: In the short run, a monopolistically competitive firm finds its balance where the cost of making one more unit equals the revenue from selling it. Firms might make extra profits, normal profits, or even losses, depending on their unique product and costs.

🎯 Exam Tip: Remember that in the short run, firms in monopolistic competition can earn super-normal profits, normal profits, or losses, just like in perfect competition, but with differentiated products.

 

Question 11. Explain the concept of selling cost.
Answer: According to Chamberlin, selling costs are expenses incurred to change the position or shape of a product's demand curve. These costs are significant in a monopolistic competition market and are generally used to attract customers. They include various expenses such as:
1. Advertising through newspapers, journals, radio, television, cinema, and posters.
2. Spending on showrooms, window displays, and exhibitions.
3. Salaries paid to salesmen.
4. Expenses for the sales department.
5. Costs for providing product samples.
6. Expenditures on commissions and other sales incentives.
Firms use two main types of advertisements: informative (to provide product details) and manipulative or competitive (to persuade and build brand loyalty).
In simple words: Selling costs are the expenses a company pays for advertising, sales staff, and promotions to make its product more appealing and increase demand.

🎯 Exam Tip: Selling costs are crucial in monopolistic competition because product differentiation allows firms to compete on non-price factors to attract and retain customers.

 

Question 12. Discuss the wastage in monopolistic competition.
Answer: Monopolistic competition often leads to various forms of wastage:
(a) Production below optimum: Firms typically produce below their optimal capacity, leading to underutilization of resources and clear waste.
(b) Survival of inefficient firms: Inefficient firms can survive by building consumer loyalty through product differentiation, even if they are not the most cost-effective.
(c) Too many varieties: Scarce resources are often used to produce many varieties of the same product, which could be better used elsewhere for more essential goods.
(d) Unnecessary selling costs: Firms incur significant, sometimes unnecessary, selling costs (like excessive advertising) to differentiate products and attract customers, adding to overall waste.
(2) Social Costs or Social Wastage:
(a) Economic costs: These costs can burden weaker sections of society, as differentiation often leads to higher prices.
(b) Forced distant purchases: Consumers may be forced to buy from distant markets at high prices, involving extra effort and cost.
Therefore, monopolistic competition needs to be regulated to be socially and economically useful.
In simple words: Monopolistic competition can waste resources by producing too many similar products, letting weak firms stay in business, and spending too much on advertising, which can also make products more expensive for people.

🎯 Exam Tip: Focus on how product differentiation, while benefiting consumers with variety, can also lead to inefficiencies and higher social costs due to excess capacity and extensive selling efforts.

 

Question 13. Write any three characteristics of imperfect competition.
Answer: Three features of imperfect competition are:
1. The number of sellers is generally more than one, and competition exists among them. However, it's not "many" as in perfect competition.
2. There is often no perfect close substitute for the product, meaning products are somewhat differentiated. This gives firms some market power.
3. Selling costs are important in this market. Firms use advertising and other promotional activities to sell their products and differentiate them from competitors.
In simple words: Imperfect competition has many sellers who compete, products that are slightly different, and companies spend money on advertising.

🎯 Exam Tip: Remember that imperfect competition is a broad term, and these characteristics are common across its various forms like monopolistic competition and oligopoly.

 

Question 14. Write any four features of oligopoly.
Answer: Four features of oligopoly are:
1. Number of sellers is less: Only a few firms dominate the market.
2. Mutual dependence among sellers: Each firm's decisions are highly influenced by the actions and reactions of its rivals.
3. Product differentiation: Products can be either homogeneous or differentiated, but differentiation is common.
4. High barriers to entry: Significant obstacles prevent new firms from easily entering the industry, helping existing firms maintain their market share.
In simple words: Oligopoly has few sellers, firms depend on each other's decisions, products can be different, and it's hard for new companies to join the market.

🎯 Exam Tip: When listing features of oligopoly, interdependence is the most crucial, as it drives the strategic behavior observed in these markets.

 

Question 16. What is meant by patent right? Clarify.
Answer: A patent right is a legal recognition granted by the government to a firm that develops or invents a new product. This right prevents any other firm or producer from manufacturing that specific product for a certain period. Once a patent right is obtained, the firm becomes the sole producer of that product, essentially creating a temporary monopoly. This encourages innovation by protecting the inventor's exclusive rights.
In simple words: A patent right is a special permission from the government that allows only one company to make and sell a new invention, stopping others from copying it.

🎯 Exam Tip: Patent rights are an important barrier to entry in many industries, allowing firms to recover research and development costs by enjoying temporary monopoly power.

 

Question 17. Differentiate between monopoly and monopolistic competition.
Answer: The following table and points highlight the differences between monopoly and monopolistic competition:

**Similarities:**
1. In both market structures, equilibrium occurs where marginal cost (MC) equals marginal revenue (MR).
2. The demand curve (or average revenue, AR curve) in both markets slopes downward from left to right, and the marginal revenue (MR) curve lies below it.
3. In both cases, the equilibrium price of the product is higher than its marginal cost.
4. Producers in both markets have some control over the price of their product, allowing for slight price adjustments.
5. The equilibrium point in both markets is below the average revenue curve.
6. Firms in both markets produce less than the optimum quantity, leading to some additional capacity.

**Dissimilarities:**
1. In a monopoly, there is only one producer, while in monopolistic competition, the number of firms is higher.
2. Product differentiation is a key feature in monopolistic competition, but it is absent in a pure monopoly.
3. A monopolist has greater control over product pricing due to the absence of competition, whereas a monopolistically competitive firm has less control as it must compete with other firms.
4. The demand curve for a monopolistic firm is steeper, indicating less elasticity, while a monopolistic competition demand curve is flatter, implying more elasticity.
5. A monopolistic firm earns extraordinary profit in the long term, while a monopolistically competitive firm earns only normal profit in the long term.
6. A monopolist can practice price discrimination, which is generally not possible in monopolistic competition.
7. In a monopolistic market, the product price is usually uniform across the market. In monopolistic competition, prices can vary due to product differentiation.
8. Sales costs are generally not found in a monopoly but are significant in monopolistic competition due to firms competing through advertising.
In simple words: Monopoly has one seller and no competition, while monopolistic competition has many sellers with slightly different products and some competition. Both have downward-sloping demand curves and aim for MR=MC. However, monopolies earn extra profits long-term, while monopolistic competition only earns normal profits.

🎯 Exam Tip: When differentiating, focus on the number of sellers, product nature (homogeneous vs. differentiated), barriers to entry, and long-run profit potential, as these are the core distinctions.

 

Question 6. When is price discrimination profitable?
Answer: Price discrimination is profitable only if the way demand changes with price (price elasticity of demand) is different in one market compared to another market.
In simple words: A seller can make more money by charging different prices in different markets if how much people buy changes differently in each market when prices change.

🎯 Exam Tip: Remember that price discrimination requires different demand elasticities in separate markets for it to be effective.

 

Question 7. What is dumping?
Answer: Dumping happens when a producer sells a product in a foreign country at a lower price (after counting transportation costs and tariffs) than the price they charge for the same product in their home country.
In simple words: Dumping means selling goods cheaper abroad than at home, often to gain market share or get rid of extra stock.

🎯 Exam Tip: Dumping is a strategy where goods are exported at prices below their domestic market value, potentially harming local industries in the importing country.

 

Question 8. What are the methods of control of monopoly?
Answer: Following are the two methods to control a monopoly:
I. Indirect Method
(a) Anti-monopoly legislation
(b) Maintenance of Fair Competition
II. Direct Method
(a) Purchaser's Association
(b) Publicity
(c) Direct price regulation
In simple words: Monopolies can be controlled in two ways: indirectly through laws against them and by ensuring fair competition, or directly through groups like buyer associations, public awareness, and government rules on prices.

🎯 Exam Tip: For this type of question, categorize methods into broad groups (like direct and indirect) and then list specific examples under each to ensure a comprehensive answer.

 

Question 10. Define monopoly according to Prof. Thomas.
Answer: According to Prof. Thomas, "Generally, the term is used to include any effective control over prices, whether it's for the supply or demand of services or goods. It means a group of manufacturers or merchants working together to control the price at which goods or services are supplied."
In simple words: Prof. Thomas said monopoly is when a group of sellers controls the supply price of goods or services.

🎯 Exam Tip: When defining terms by economists, always quote the definition accurately and mention the economist's name to get full marks.

 

Question 11. Define monopoly according to Lerner.
Answer: According to Lerner, "A monopolist is a seller who faces a demand curve that is falling for their product."
In simple words: Lerner said a monopolist is a seller whose product's demand goes down as they raise the price.

🎯 Exam Tip: Understanding that a monopolist faces a downward-sloping demand curve is key, as it means they can influence price by changing quantity.

 

Question 12. Define monopoly according to K.E. Boulding.
Answer: According to K.E. Boulding, "A pure monopolist is a firm that produces a product with no effective substitutes from other firms. This means that even if the monopolist makes a lot of profit, other firms cannot easily enter the market to offer similar products and attract buyers away."
In simple words: K.E. Boulding defined pure monopoly as a single firm making a product with no real substitutes, so other firms can't easily join in even if profits are high.

🎯 Exam Tip: Highlight the 'no effective substitutes' and 'barrier to entry' aspects when discussing Boulding's definition of a pure monopoly.

 

Question 13. Define monopoly according to John D. Sumur.
Answer: Pure monopoly means that the demand for the product has zero elasticity, which is very different from the infinite elasticity of demand seen in pure competition.
In simple words: John D. Sumur said that in a pure monopoly, changing the price does not change demand at all, unlike in pure competition where demand changes a lot.

🎯 Exam Tip: Focus on the concept of 'zero elasticity of demand' as the defining feature of pure monopoly according to Sumur.

 

Question 14. What is imperfect competition?
Answer: Imperfect competition is a market situation where there are many sellers, but they offer products that are slightly different or unequal, which is the opposite of a completely competitive market where all products are identical.
In simple words: Imperfect competition is when many sellers offer slightly different products, not identical ones.

🎯 Exam Tip: Remember that imperfect competition includes market structures like monopolistic competition and oligopoly, characterized by product differentiation.

 

Question 16. State a feature of monopolistic competition.
Answer: In monopolistic competition, buyers and sellers do not have complete information about the product's price. This is because it is hard to compare products from different firms due to product differentiation.
In simple words: A key feature of monopolistic competition is that buyers and sellers don't have perfect information about prices because products are all a bit different.

🎯 Exam Tip: When describing features, always link them back to the core concept, such as how product differentiation leads to imperfect knowledge of prices.

 

Question 17. What is the concept of selling cost?
Answer: Selling costs are a significant part of the total cost in imperfect or monopolistic competition. These are expenses that firms spend to promote their sales, such as advertisements and paying salespeople.
In simple words: Selling costs are the money spent by companies on advertising and sales staff to sell their products, especially when their products are different from others.

🎯 Exam Tip: Selling costs are crucial for product differentiation and increasing market share in monopolistic competition, unlike in perfect competition where they are unnecessary.

 

Question 18. What do you understand by Oligopoly?
Answer: Oligopoly is a market structure where there are two or more, but not many, producers or sellers of a product.
In simple words: Oligopoly is a market where only a few main sellers control the industry.

🎯 Exam Tip: The key characteristic of an oligopoly is the small number of interdependent firms, which leads to strategic decision-making.

 

Question 19. What is Kinked Demand curve?
Answer: The Kinked Demand curve is a model used to explain how prices are set in an oligopolistic market. It was first introduced by Paul Sweezy in 1934.
In simple words: The Kinked Demand curve helps explain why prices often stay stable in a market with only a few big sellers.

🎯 Exam Tip: The Kinked Demand curve model suggests that firms in an oligopoly are reluctant to change prices due to fear of losing customers or starting a price war.

 

Question 20. What is collusive oligopoly?
Answer: Collusive oligopoly is a situation where firms in a particular industry decide to work together. Their goal is to maximize their combined profit as a single unit and then agree on how to share the market.
In simple words: Collusive oligopoly is when a few companies in an industry team up to act like one big company to make more money together and share the market.

🎯 Exam Tip: Collusion in an oligopoly aims to reduce competition and often leads to higher prices and lower output, similar to a monopoly.

 

Question 22. Define oligopoly according to Prof. George J. Stigler.
Answer: According to Prof. George J. Stigler, "Oligopoly is a situation where a firm bases its market decisions partly on what it expects a few close rivals to do."
In simple words: Stigler said oligopoly is when a company makes choices based on how its competitors might react.

🎯 Exam Tip: The concept of 'interdependence' among firms is central to Stigler's definition of oligopoly.

 

Question 23. Define Monopolistic competition according to Leftwitch.
Answer: According to Leftwich, "Monopolistic competition is a market situation where there are many sellers of a particular product, but each seller's product is unique in some way in the minds of customers compared to other sellers' products."
In simple words: Leftwich said monopolistic competition means many sellers offer products that buyers see as slightly different from each other.

🎯 Exam Tip: The key takeaway from Leftwich's definition is the presence of many sellers with differentiated products.

 

RBSE Class 12 Economics Chapter 12 Short Answer Type Questions

 

Question 1. What are the four features of monopoly?
Answer: Following are the 4 features of monopoly:
(a) Single Seller – In a monopoly, there is only one producer of the product.
(b) Firm is also an Industry – Because there is only one firm, there's no difference between the firm and the entire industry. The monopoly firm itself is the industry.
(c) Substitute of the Commodity – All units of the product are identical, and there are no close substitutes available.
(d) No Entry of new firms – Other firms are restricted from entering this market.
In simple words: Monopoly has four main features: only one seller, the firm is the whole industry, no close substitute products, and new companies cannot enter the market.

🎯 Exam Tip: Clearly listing and briefly explaining each feature of a monopoly will ensure you cover all aspects of the question.

 

Question 2. Explain the nature of demand and revenue curve under monopoly.
Answer: The demand curve for a monopoly firm is the same as the market demand curve. This curve slopes downwards, showing that more of a product is demanded at a lower price and less at a higher price. The market demand curve is also the monopolist's average revenue curve. So, the average revenue curve for a monopolist slopes downwards, meaning a higher quantity of product is sold at a lower price.
In simple words: For a monopoly, the demand curve slopes downwards, meaning they must lower prices to sell more. This demand curve is also their average revenue curve.

🎯 Exam Tip: Emphasize that a monopolist is a price maker and faces a downward-sloping demand curve, unlike a firm in perfect competition.

 

Question 3. The monopolist is able to gain super-normal profit in the long run. How?
Answer: Even in the long run, a monopoly firm tends to protect its extra profit. Entry into the industry is blocked, meaning no new firms can enter the market, unlike in perfect competition. Therefore, when a monopolist earns long-lasting super-normal benefits, no other producer can enter the market to share these high profits. So, these long-lasting super-normal benefits do not end. Because new firms cannot enter and there are no substitutes in the market, the monopolist doesn't necessarily have an ideal-sized plant in the long run or has to use it at full capacity. The monopolist will adjust their plant according to market demand.
In simple words: Monopolists can keep making huge profits in the long run because new businesses can't easily join the market to compete with them. They adjust their production to meet demand.

🎯 Exam Tip: The absence of free entry and exit is the primary reason a monopolist can sustain super-normal profits in the long run.

 

Question 4. Explain measurement of monopoly power.
Answer: Not all monopolists have the same amount of power; some are more powerful than others. Their ability to influence price is not always uniform.
(a) The greater the difference between marginal cost and price, the higher the monopolist's power will be.
(b) Powerful monopolists can earn larger monopoly profits.
(c) When demand is less sensitive to price changes (less elastic), the monopoly power will be greater.
(d) Monopoly power will be less when the cross-elasticity of demand (how much demand for one product changes when the price of another product changes) is high.
In simple words: Monopoly power is measured by how much the monopolist can set prices above their costs. It's stronger when demand doesn't change much with price, and weaker if customers can easily switch to other products.

🎯 Exam Tip: Monopoly power is directly related to the price-marginal cost gap and inversely related to the elasticity of demand for the product.

 

Question 5. When is price discrimination profitable? Why?
Answer: Price discrimination is profitable when, at a single monopoly price, the price elasticity of demand in one market is different from that in another market. Only when demand reacts differently to price changes in two markets will the extra income from selling one more unit (marginal revenue) be greater in one market than the other. This motivates the seller to shift some units from one market to another and charge different prices, which helps them maximize profits.
In view of the above two essential conditions, price discrimination is possible in the following cases:
(a) The nature of the product or service is such that it cannot be transferred from one market to another.
(b) There are long distances or trade barriers between the two markets where price discrimination is practiced.
(c) There is a legal approval for price discrimination.
(d) Some buyers prefer certain products or have biases, leading them to buy at higher prices.
(e) Buyers might be unaware or lazy.
In simple words: Price discrimination works best when people in different markets react differently to price changes. This lets a seller move products to the market where they can get more money, maximizing profit. It is also possible when products can't be moved between markets, if there are long distances or trade barriers, legal support for different prices, buyer preferences, or buyer ignorance.

🎯 Exam Tip: For price discrimination to be effective, markets must be separable, and demand elasticity must differ between them, preventing arbitrage.

 

Question 7. Write down a brief note on maintenance of Fair Competition in anti-monopoly legislation.
Answer: A monopolist often restricts supply and charges high prices because they are confident of having no competitors. If faced with the possibility of competition, a monopolist will not freely use their monopoly powers.
Governments should prohibit unfair competitive practices that monopolists use to harm or destroy rival firms. However, implementing this policy is not always easy.
1. The government can set a price to regulate, but monopolies may offer other deals to eliminate rivals.
2. New competitors usually have limited money to start production successfully.
3. Monopolists use mass production, which lowers costs and increases efficiency, due to their established position.
4. Monopolists have strong financial standing, allowing them to spend a lot on advertising to capture the market and force competitors out.
5. Monopolists can even create new companies under their own name to sell products that compete with their rivals.
In simple words: Governments try to control monopolies through laws that promote fair competition. This stops monopolies from limiting supply or setting very high prices. However, it's hard to make sure competition is truly fair because monopolies have many ways to keep their power, like huge budgets and control over production.

🎯 Exam Tip: Anti-monopoly legislation aims to prevent monopolists from abusing their market power, but its effectiveness depends on thorough regulation and enforcement against various tactics.

 

Question 9. Explain short run equilibrium under monopolistic competition.
Answer: In the short run, a monopolistic competitive firm reaches equilibrium when its marginal cost (MC) equals its marginal revenue (MR), and MC is rising at this output level.
Short-period equilibrium does not mean all firms have the same price. Prices can vary because the products are not identical, and production costs also differ among firms. Generally, larger firms have lower average costs, while smaller firms have higher costs. Therefore, some firms might earn supernormal profits, others might earn normal profits, and some might even incur losses in the short run. So, a monopolistic competitive firm in the short run may:
(a) Earn super-normal profits, meaning Average Revenue (AR) > Average Cost (AC).
(b) Earn normal profits, meaning AR = AC.
(c) Incur losses, meaning AR < AC.
In simple words: In the short term, a company in monopolistic competition finds its balance where the extra cost of making one more item is equal to the extra money it earns from selling it. During this time, some companies might make big profits, some might just break even, and others might lose money, depending on their costs and sales.

🎯 Exam Tip: Remember that in the short run, firms in monopolistic competition can earn super-normal profits, normal profits, or incur losses, depending on their cost and revenue structures relative to market demand.

 

Question 11. Explain the concept of selling cost.
Answer: According to Chamberlin, "Selling costs are those costs incurred to change the position or shape of the demand curve for a product."
Generally, the following expenses are included in selling cost:
1. Advertising through newspapers, journals, radio, television, cinema, and posters.
2. Spending on showrooms, display windows, and exhibitions.
3. Salaries paid to salespeople.
4. Expenses for the sales department.
5. Expenditure on providing samples.
6. Expenditure on commissions and other incentives.
Selling costs play a very important role in a monopolistic competition market. Firms typically use two types of advertisements to attract customers:
• Informative advertisement
• Manipulative or Competitive advertisement.
In simple words: Selling costs are expenses like advertising that companies use to influence customer demand for their products. These costs include ads, showrooms, staff salaries, and free samples, all aimed at attracting more buyers and are very important in markets where products are different.

🎯 Exam Tip: Clearly list the types of expenses that fall under selling costs and explain their purpose in shifting or shaping the demand curve.

 

Question 12. Discuss the wastage in monopolistic competition.
Answer: Wastage in monopolistic competition can be seen in two main ways:
(1) Production Wastage:
(a) Firms produce below their ideal output level, which means resources are not used efficiently.
(b) Even inefficient firms can survive by building customer loyalty, leading to more wasted resources.
(c) Too many varieties of the same product are made using limited resources, which could be used better elsewhere.
(d) Selling costs, like extensive advertising, are often unnecessary.
(2) Social Costs or Social Wastage:
(a) The economic costs are a burden, especially on weaker parts of society.
(b) Consumers might have to buy from distant markets, involving a lot of effort when prices are too high.
Therefore, it is necessary to control monopolistic competition properly to make it socially and economically useful.
In simple words: Monopolistic competition often leads to waste because companies don't produce at their most efficient level, too many similar products are made, and there's a lot of unnecessary spending on advertising. This creates economic and social costs, so it needs to be regulated to be helpful to society.

🎯 Exam Tip: Focus on how product differentiation and selling costs, while defining monopolistic competition, also lead to inefficiencies and underutilization of resources.

 

Question 13. Write any three characteristics of imperfect competition.
Answer: Features of imperfect competition are:
1. There are many sellers in imperfect competition, and there is competition among them.
2. The products made in an imperfect market do not have a close substitute.
3. Sales costs are important in this market because each firm uses advertising to sell its product.
In simple words: Imperfect competition has many sellers, products don't have perfect substitutes, and companies spend money on advertising to sell their goods.

🎯 Exam Tip: Remember that imperfect competition covers a range of market structures, all sharing the key traits of product differentiation and some control over price.

 

Question 14. Write any four features of oligopoly.
Answer: Four features of oligopoly are:
1. The number of sellers is small.
2. There is mutual dependence among sellers.
In simple words: In an oligopoly, there are only a few sellers, and they all watch each other's actions closely because what one seller does affects the others.

🎯 Exam Tip: The small number of firms and their interdependence are the most crucial features of oligopoly, leading to complex strategic behavior.

 

Question 16. What is meant by patent right? Clarify.
Answer: A patent right is when a firm that develops or invents a product gets official government recognition, meaning no other firm or producer can make that product. Once a firm gets the patent right, it becomes the only producer of that product.
In simple words: A patent right is a legal protection given to a company for its new invention or product, stopping anyone else from producing it and making that company the sole seller.

🎯 Exam Tip: Patent rights grant a temporary monopoly, encouraging innovation by protecting inventors' investments and allowing them exclusive profits for a period.

 

Question 17. Differentiate between monopoly and monopolistic competition.
Answer: Difference between monopoly and monopolistic competition:

In simple words: Monopoly has only one seller with unique products and no new firms can enter, so there's no real competition and no need for selling costs. Monopolistic competition has many sellers, products are different, new firms can enter, there is competition, and selling costs are important.

🎯 Exam Tip: When comparing market structures, always use a table format to clearly highlight the differences across key characteristics like number of firms, product nature, and entry barriers.

 

Question 1. "Monopolistic market is an extreme situation". Discuss this statement.
Answer: Monopoly means a single seller. A monopolist has no rivals or competitors, implying that competition in a monopolistic market structure is very small or non-existent.
In monopoly, there is only one producer or seller of a product with no close substitutes. The absence of competition and complete control over the market by a single firm are core properties of monopoly. Maintaining this situation depends on the firm's ability to discourage potential competitors.
Definitions of Monopoly:
According to Prof. Thomas, "Generally, the term is used to include any effective price control whether it's for the supply or demand of services or goods. It means a group of manufacturers or merchants working together to control the price at which goods or services are supplied."
According to K.E. Boulding, "A pure monopolist is a firm that produces a product with no effective substitutes from other firms. This means that even if the monopolist makes a lot of profit, other firms cannot easily enter the market to offer similar products and attract buyers away."
According to John D. Sumur, "Pure monopoly implies zero elasticity of demand, which is very different from the infinite elasticity of demand seen in pure competition."
Every monopolist aims to maximize profit. They achieve this where marginal cost (MC) equals marginal revenue (MR). We need to see how a monopolist decides on price discrimination in different markets. If a discriminating monopolist also wants to maximize profit like any simple monopolist, they adjust output to make marginal revenue equal to marginal cost.
In simple words: A monopolistic market is called extreme because it has only one seller with full control, no competitors, and no close substitute products. Economists like Thomas, Boulding, and Sumur define it as a market where one firm controls prices and faces no competition. The main goal of a monopolist is to make the most profit by carefully setting prices.

🎯 Exam Tip: To thoroughly discuss a statement about market extremes, define the market, cite relevant economists, and explain how the market structure achieves its objectives, such as profit maximization.

 

Question 2. What is monopolistic competition? Explain and illustrate with the- help of a diagram how in the long run a firm under monopolistic competition makes only normal profits.
Answer: The concept of monopolistic competition, developed by E.H. Chamberlin, was more realistic than perfect competition or pure monopoly. Before Chamberlin, monopoly and competition were seen as two opposite market structures. Chamberlin showed that in most real-world economic situations, both monopoly and competitive elements are present.
Chamberlin's concept of monopolistic competition is a mix of competition and monopoly. The main difference between the short-run and long-run in monopolistic competition is that in the long-term, new companies can enter the market. When existing companies are making good economic profits, new businesses are attracted to these benefits and choose to enter the market. Unlike a monopoly, there are no barriers to entry in monopolistic competition. Therefore, it is easy for new companies to enter the market in the long run.
This means the demand curve for a firm in monopolistic competition slopes downwards, and the marginal revenue curve lies below it. This implies that a firm is not a price taker but has some influence over its product's price. If a producer sets a higher price, they will sell less; if they set a lower price, they will sell more. Thus, a firm in monopolistic competition chooses a price-output combination to maximize profit.
When new companies enter, the supply of differentiated products increases, shifting the firm's market demand curve to the left. As the market grows, the firm's demand curve keeps moving left until it becomes tangent to the average total cost curve at the maximum profit level, as shown in the diagram below. At this point, the firm's financial profits become zero, and there is no incentive for new firms to enter. So, in the long run, competition from new entrants leads to normal profits for each company in a monopolistic competitive market, just like in a perfectly competitive firm.
In simple words: Monopolistic competition is a market type where many firms sell similar but slightly different products. In the long run, new companies keep entering until no one is making big profits, only normal profits. This happens when the firm's average cost curve just touches its demand curve, meaning the price covers all costs but doesn't leave extra profit.

🎯 Exam Tip: When illustrating long-run equilibrium in monopolistic competition, ensure your diagram shows the downward-sloping AR and MR curves, with the ATC curve tangent to the AR curve at the profit-maximizing output, indicating normal profits.

 

RBSE Class 12 Economics Chapter 12 Numerical Questions

 

Question 1. From the following table, determine numerically the best level of output for the monopolist hy (a) Total approach and (b) Marginal approach.
Answer:
(a) Total Approach

The monopolist would be in equilibrium when he produces and sells 3 or 4 units of the commodity, where the maximum profit of Rs 6 is achieved at a price of Rs 16 or Rs 14 respectively.
(b) Marginal Approach
The best level of output for the monopolist would be 4 units. At this output, both Marginal Revenue (MR) and Marginal Cost (MC) are equal to 8, and the monopolist gets a maximum profit of Rs 6.
In simple words: To find the best output level for a monopoly, we look at two things. First, by checking total profit, we see that selling 3 or 4 units gives the highest profit of Rs 6. Second, by looking at marginal profit (the extra profit from each unit), the best output is 4 units, because at this point, the extra money earned from selling one more unit (MR) is equal to the extra cost of making it (MC), which is Rs 8.

🎯 Exam Tip: For numerical questions involving total and marginal approaches, always create clear tables showing all calculations. For the total approach, identify the output level with the highest total profit. For the marginal approach, identify the output level where Marginal Revenue (MR) equals Marginal Cost (MC).

 

Question 2. From the following table, find out the best level of output for the monopolist by Marginal approach.
Answer:
Marginal Approach

It is evident that when MR = MC, the monopolist gets maximum profit. Here the monopolist maximizes his total profits at Rs 15 when he produces and sells 2.5 units of output at the price of Rs 22.00.
In simple words: To find the best output, we look for the point where the extra money earned from selling one more unit (Marginal Revenue) equals the extra cost of making it (Marginal Cost). From the table, this happens when 2.5 units are produced and sold at Rs 22.00, resulting in the highest profit of Rs 15.

🎯 Exam Tip: When using the marginal approach, calculate MR and MC for each output level. The profit-maximizing output is where MR = MC or where MR is just greater than MC before MC exceeds MR.

 

Question 2. From the following table, find out the best level of output for the monopolist by Marginal approach.

Answer:
To find the best level of output by the Marginal Approach, we need to calculate Total Revenue (TR), Marginal Revenue (MR), Marginal Cost (MC), and Profit. The profit is maximized where MR is equal to MC, or where the difference between TR and TC is the largest.It is evident that when marginal revenue (MR) is approximately equal to marginal cost (MC), the monopolist gets maximum profit. Here, the monopolist maximizes total profits at Rs. 15 when producing and selling 2.5 units of output at a price of Rs. 22.00.
In simple words: We calculate total earnings and costs for each output level. The biggest profit is Rs. 15, achieved when 2.5 units are sold at Rs. 22 each. This is where marginal revenue is closest to marginal cost.

🎯 Exam Tip: Remember to calculate all intermediate columns (TR, MR, MC, Profit) accurately. The profit-maximizing output is where MR = MC, or where total profit is highest.
