Part - A

Multiple Choice Questions

 

Question 1. Every able bodied person who is willing to work at the prevailing wage rate is employed called as
(a) Full employment
(b) Under employment
(c) Unemployment
(d) Employment opportunity
Answer: (a) Full employment
In simple words: When everyone who can and wants to work at the normal pay rate has a job, it's called full employment. This is an important goal for any economy.

🎯 Exam Tip: Remember that full employment doesn't mean zero unemployment; it typically allows for some frictional or structural unemployment that is unavoidable.

 

Question 2. Structural unemployment is a feature in a
(a) Static society
(b) Socialist society
(c) Dynamic society
(d) Mixed economy
Answer: (c) Dynamic society
In simple words: Structural unemployment happens in economies that are changing a lot. When industries shift or new technologies come in, some jobs become old and new skills are needed.

🎯 Exam Tip: Distinguish structural unemployment from other types by focusing on long-term changes in the economy's structure, like new technologies or industries.

 

Question 3. In disguised unemployment, the marginal productivity of labour is
(a) Zero
(b) One
(c) Two
(d) Positive
Answer: (a) Zero
In simple words: Disguised unemployment means there are more people working than actually needed. If you remove one person, the amount of work done doesn't change, so that person's extra contribution is zero. This is often seen in agricultural sectors.

🎯 Exam Tip: Understand that zero marginal productivity is the key characteristic of disguised unemployment, meaning adding or removing a worker does not affect total output.

 

Question 4. The main conception of the classical Economic Theory is
(a) Under employment
(b) Economy is always in the state of equilibrium
(c) Demand creates its supply
(d) Imperfect competition
Answer: (b) Economy is always in the state of equilibrium
In simple words: Classical economic theory believes that the economy naturally balances itself out and tends to be in a steady state. Prices and wages adjust automatically to keep things stable.

🎯 Exam Tip: Remember that classical theory assumes market forces will always restore equilibrium, leading to full employment without external intervention.

 

Question 5. J.B. Say is a
(a) New classical Economist
(b) Classical Economist
(c) Modern Economist
(d) New Economist
Answer: (b) Classical Economist
In simple words: J.B. Say was a well-known classical economist. He is famous for his law that says "supply creates its own demand."

🎯 Exam Tip: Associate J.B. Say primarily with the classical school of thought and the concept of "Say's Law" where production drives consumption.

 

Question 6. According to Keynes, which type of unemployment prevails in capitalist economy?
(a) Full employment
(b) Voluntary unemployment
(c) Involuntary unemployment
(d) Under employment
Answer: (d) Under employment
In simple words: Keynes believed that in a capitalist economy, there is often not enough demand to give everyone a job. So, instead of full employment, there is often a situation where people are working but not as much as they could or want to.

🎯 Exam Tip: Understand that Keynesian theory challenges the classical idea of automatic full employment, suggesting that economies often settle at an 'under-employment equilibrium'.

 

Question 7. The core of the classical theory of employment is
(a) Law of Diminishing Return
(b) Law of demand
(c) Law of markets
(d) Law of consumption
Answer: (c) Law of markets
In simple words: The main idea in classical employment theory is that markets work well on their own. This often refers to Say's Law, where producing goods automatically creates the demand for them.

🎯 Exam Tip: Link the "Law of Markets" directly to J.B. Say's Law, which is central to classical economic thought on employment.

 

Question 8. Keynes attributes unemployment to
(a) A lack of effective supply
(b) A lack of effective demand
(c) A lack of both
(d) None of the options
Answer: (b) A lack of effective demand
In simple words: Keynes felt that unemployment happens because people and businesses don't spend enough money. If there isn't enough demand for goods and services, companies won't hire more workers.

🎯 Exam Tip: Focus on 'effective demand' as the primary driver of employment in Keynesian economics; a shortfall in this leads to unemployment.

 

Question 9. Which of the following brings equality between saving and investment?
(a) Demand
(b) Supply
(c) Capital
(d) Interest
Answer: (d) Interest
In simple words: In classical economics, the interest rate changes to make sure that the money people save equals the money businesses want to invest. This balance helps keep the economy stable.

🎯 Exam Tip: Remember that in classical economics, the rate of interest is the mechanism that equates savings and investment in the capital market.

 

Question 10. Which economic theory is a turning point in the development of modern economic theory?
(a) Keynes
(b) Say's
(c) Classical
(d) Employment
Answer: (a) Keynes
In simple words: John Maynard Keynes's ideas marked a big change in how people thought about economics. His theories helped shape modern economic policies, especially regarding government involvement in the economy.

🎯 Exam Tip: Recognize Keynesian theory as a significant departure from classical thought, especially concerning the role of government in managing economic fluctuations.

 

Question 11. The basic concept used in Keynes Theory of Employment and Income is
(a) Aggregate demand
(b) Aggregate supply
(c) Effective demand
(d) Marginal propensity to consume
Answer: (c) Effective demand
In simple words: Keynes focused on 'effective demand' as the key to understanding employment and income levels. This is the total spending in an economy that actually causes production and hiring.

🎯 Exam Tip: Always highlight 'effective demand' as the central concept in Keynesian economics; it determines the level of employment and output.

 

Question 12. The component of aggregate demand is
(a) Personal demand
(b) Government expenditure
(c) Only export
(d) Only import
Answer: (b) Government expenditure
In simple words: Government spending is one of the important parts that make up the total demand in an economy. When the government spends more, it adds to the overall demand for goods and services.

🎯 Exam Tip: Remember the four main components of aggregate demand: consumption, investment, government spending, and net exports.

 

Question 13. Aggregate supply is equal to
(a) 'C + I + G
(b) C+S+T + (x-m)
(c) C+ S+ T+ (x – m)
(d) C+ S+ T+ Rf
Answer: (d) C+ S+ T+ Rf
In simple words: The total supply of goods and services in an economy is made up of what people spend (C), what they save (S), taxes (T), and money from foreign sources (Rf). This shows all the income available for use.

🎯 Exam Tip: Understand that aggregate supply represents the total value of goods and services produced, and its components reflect how that income is disposed of by households and government.

 

Question 14. Keynes theory pursues to replace Laissez Faire by
(a) No government intervention
(b) Maximum intervention
(c) State intervention in certain situation
(d) Private Sector Intervention
Answer: (c) State intervention in a certain situation
In simple words: Keynes believed that the government should step in to help the economy, especially during tough times like recessions. He thought that markets don't always fix themselves, so the government needs to act. This was a big shift from the 'laissez-faire' idea of no government involvement.

🎯 Exam Tip: Keynesian economics advocates for targeted government intervention to stabilize the economy, especially when market forces fail to achieve full employment.

 

Question 15. In Keynes theory of employment and income, which is the basic cause of economic depression?
(a) Less production
(b) More demand
(c) Inelastic supply
(d) Less aggregate demand in relation to productive capacity
Answer: (d) Less aggregate demand in relation to productive capacity
In simple words: According to Keynes, a major economic downturn happens when people and businesses aren't buying enough goods and services compared to what the economy can actually produce. This low demand then leads to less production and job losses.

🎯 Exam Tip: Connect economic depression in Keynesian theory directly to a deficiency in aggregate demand, which prevents the economy from utilizing its full productive potential.

 

Question 16. Classical theory advocates
(a) Balanced budget
(b) Unbalanced budget
(c) Surplus budget
(d) Deficit budget
Answer: (a) Balanced budget
In simple words: Classical economists generally supported the idea of a balanced budget, meaning the government should not spend more than it collects in taxes. They believed this leads to economic stability without causing inflation.

🎯 Exam Tip: Remember that classical economists favored fiscal prudence and a balanced budget, believing that market forces were sufficient for economic stability without government debt.

 

Question 17. Keynes theory emphasized on ___________ equilibrium.
(a) Very short run
(b) Short-run
(c) Very long run
(d) Long run
Answer: (b) Short-run
In simple words: Keynes mainly focused on what happens in the economy in the near future, or the 'short-run'. He believed that many economic problems, like unemployment, need solutions that work quickly rather than waiting for long-term market adjustments.

🎯 Exam Tip: Recognize that Keynesian economics largely analyzes and proposes solutions for short-run economic fluctuations, contrasting with classical long-run perspectives.

 

Question 18. According to classical theory, the rate of interest is a reward for
(a) Investment
(b) Demand
(c) Capital
(d) Saving
Answer: (d) Saving
In simple words: In classical thinking, interest is seen as the payment people get for choosing to save their money instead of spending it right away. It's an incentive to postpone consumption and provide funds for investment.

🎯 Exam Tip: Understand the classical view of interest as a return for abstaining from current consumption, thereby linking savings to the supply of loanable funds.

 

Question 19. In Keynes theory, the demand for and supply of money are determined by
(a) Rate of interest
(b) Effective demand
(c) Aggregate demand
(d) Aggregate supply
Answer: (a) Rate of interest
In simple words: Keynes believed that how much money people want to hold and how much is available in the economy are mainly affected by the interest rate. When interest rates are high, people want to hold less cash and save more.

🎯 Exam Tip: In Keynesian theory, the demand for money (liquidity preference) is inversely related to the interest rate, a crucial concept for understanding monetary policy.

 

Question 20. Say's law stressed the operation of ___________ in the economy.
(a) Induced price mechanism
(b) Automatic price mechanism
(c) Induced demand
(d) Induced investment
Answer: (b) Automatic price mechanism
In simple words: Say's Law suggested that markets naturally adjust themselves through prices. It believed that any imbalance between supply and demand would quickly be fixed by price changes without needing outside help.

🎯 Exam Tip: Connect Say's Law to the classical belief in self-regulating markets, where flexible prices ensure full employment and allocate resources efficiently.

Part - B

Answer The Following Questions In One Or Two Sentences.

 

Question 21. Define full employment.
Answer: Full employment refers to a situation where every able-bodied person who is willing to work at the current wage rate finds a job. In simpler terms, it means all people who want to work and can work have employment or a job. It signifies the efficient use of human resources in an economy.
In simple words: Full employment means everyone who is able and wants to work at the normal pay rate has a job.

🎯 Exam Tip: When defining full employment, emphasize both willingness and ability to work at the prevailing wage rate, not just having a job.

 

Question 22. What is the main feature of rural unemployment?
Answer: The main characteristic of unemployment in rural areas is the presence of disguised unemployment and seasonal unemployment. These types of unemployment are very common in agricultural economies. Disguised unemployment often means more workers are employed than technically needed for a task.
In simple words: Rural unemployment mainly involves hidden unemployment (disguised) and jobs that only exist during certain times of the year (seasonal).

🎯 Exam Tip: When discussing rural unemployment, always mention disguised and seasonal unemployment as key distinguishing features, often tied to agriculture.

 

Question 23. Give a short note on frictional unemployment.
Answer: Frictional unemployment, also known as temporary unemployment, happens when there is a short-term mismatch between the available jobs and the workers looking for jobs. This type of unemployment occurs because people are in the process of changing jobs, or searching for their first job. For example, it can be due to workers moving between regions or taking time to find a suitable new role. Workers who lose jobs and are currently searching for new ones are also included in frictional unemployment.
In simple words: Frictional unemployment is temporary unemployment when people are moving between jobs or looking for new ones. It's a normal part of a changing job market.

🎯 Exam Tip: Emphasize the 'temporary' and 'transitional' nature of frictional unemployment, highlighting that it's a natural part of a healthy labor market.

 

Question 24. Give reasons for labour retrenchment at the present situation.
Answer:

• Capital intensive techniques: Companies use more machines and less human labor.
• Invention and innovations: New ways of doing things or new technologies can replace human workers.
• Labor-saving devices: Tools and machines that reduce the need for many workers are a reason for jobs to be cut.

These factors reduce the demand for human labor, leading to retrenchment.
In simple words: Jobs are cut when companies use more machines, new inventions replace workers, or tools are used that need fewer people.

🎯 Exam Tip: Focus on technological advancements and capital investment as primary drivers of labor retrenchment, showing how efficiency can lead to job displacement.

 

Question 25. List out the assumptions of Say's law.
Answer: Say's Law of the market is based on the following key assumptions:

1. No single buyer or seller can influence the market price of goods or inputs.
2. There is always full employment in the economy.
3. People make economic choices based on their own self-interest.
4. A "laissez-faire" policy (no government interference) is needed for the economy to automatically adjust to full employment.
5. There is perfect competition in both labor and product markets.
6. Wages and prices are flexible, meaning they can easily go up or down.
7. Money is only used as a way to exchange goods and services, not to be hoarded.
8. The theory is mainly for the long-run economic analysis.
9. There is no chance of too much production or unemployment for a long time.

These assumptions underpin the classical belief in self-regulating markets.
In simple words: Say's Law assumes markets work perfectly on their own, prices and wages change easily, there's always enough demand for what's made, and the government doesn't need to get involved.

🎯 Exam Tip: Remember that Say's Law relies on strong assumptions like full employment, perfect competition, and flexible prices to suggest that supply automatically creates its own demand.

 

Question 26. What is effective demand?
Answer:

• Effective demand represents the total amount of money that people actually spend on goods and services produced by industries.
• It is the total demand in an economy that leads to real output and employment.
• Effective demand is also equal to the national income of a country.

It plays a crucial role in determining the level of economic activity.
In simple words: Effective demand is the actual money people spend on goods and services. It shows how much the economy is truly buying and producing.

🎯 Exam Tip: Define effective demand as the actual aggregate expenditure in an economy, emphasizing its role as the determinant of output and employment in Keynesian theory.

Part - C

Answer The Following Questions In A Paragraph.

 

Question 27. What are the components of aggregate supply?
Answer: Aggregate supply refers to the total value of goods and services produced in an economy over a specific period. The total output generated equals the national product. The four main components of aggregate supply are:

1. Consumption (C): The spending by households on goods and services.
2. Savings (S): The part of income not spent on consumption.
3. Taxes (T): Payments made to the government.
4. Net Foreign Remittances (Rf): Money received from abroad, representing income from exports minus imports.

These components show how the income generated in an economy is distributed and utilized.
In simple words: Aggregate supply is all the goods and services an economy produces. Its main parts are what people spend, what they save, taxes they pay, and money coming from or going to other countries.

🎯 Exam Tip: Clearly state the components of aggregate supply (C, S, T, Rf) as distinct from aggregate demand, explaining that they represent the disposal of national income.

 

Question 28. Explain the following in short
(i) Seasonal unemployment
(ii) Frictional unemployment
(iii) Educated unemployment
Answer:
(i) Seasonal unemployment: This type of unemployment happens only during certain times of the year. It affects industries that have busy and slow periods, like agriculture or tourism. For instance, farmers might be unemployed after harvest season.
(ii) Frictional unemployment: This temporary unemployment happens when people are between jobs or are searching for their first job. It arises from the time it takes to match job seekers with available positions due to factors like imperfect information or geographical immobility. This is a common and short-lived type of unemployment.
(iii) Educated unemployment: Sometimes, educated people are either underemployed (working jobs below their skill level) or completely unemployed. This occurs when their qualifications do not match the jobs available in the market or when there are not enough suitable jobs for them.
In simple words: Seasonal unemployment happens at specific times of the year; frictional unemployment is temporary as people change jobs; and educated unemployment is when educated people can't find suitable work.

🎯 Exam Tip: For each type of unemployment, focus on its primary cause and duration to differentiate them clearly.

 

Question 29. Write a short note on the implications of Say's law.
Answer: Say's Law implies several things for an economy:

1. It suggests there is no chance of overproduction or long-term unemployment because supply creates its own demand.
2. If there are unused resources, it's always profitable to employ them until full employment is reached, assuming factors are paid fairly.
3. Because an automatic price mechanism exists, there's no need for government intervention in the economy.
4. Interest rates ensure that savings and investment are always equal.
5. Money primarily serves as a way to exchange goods, not as something people hold onto (idle money).

These implications lead to a belief in self-regulating markets and minimal government role.
In simple words: Say's Law means that producing goods always creates enough demand to buy them, so there's no unemployment or need for government help. It suggests markets fix themselves.

🎯 Exam Tip: When discussing Say's Law implications, highlight the belief in automatic market adjustment, the absence of overproduction, and the limited role for government intervention.

 

Question 30. Explain Keynes theory in the form of a flow chart.
Answer: Keynes's theory can be explained through a flow chart showing how various factors influence income, output, and employment. The key idea is that aggregate demand drives the economy, which then determines employment levels. The chart below illustrates the interconnectedness of these factors, starting from income and moving through consumption, investment, and liquidity preferences to finally determine the supply of money and the rate of interest, all impacting the economy's output and employment levels.
In simple words: This chart shows how different parts of the economy, like how much people spend and save, connect to each other. It explains that total spending drives how many jobs there are and how much money everyone earns.

🎯 Exam Tip: When drawing flow charts, ensure clear labels, correct directional arrows, and logical sequencing of economic concepts to demonstrate understanding of their interrelationships.

 

Question 31. What is aggregate demand? Mention its components.
Answer: Aggregate demand refers to the total money that businesses expect to receive when they sell the goods produced by all the workers they hire. It is the overall expected income or revenue from selling goods at different levels of employment. In simple terms, it's the total demand for all finished goods and services in an economy.
The aggregate demand has the following four main components:

• Consumption demand: Spending by households on goods and services.
• Investment demand: Spending by businesses on capital goods like machinery and buildings.
• Government expenditure: Spending by the government on public services and infrastructure.
• Net Export (export-import): The difference between what a country sells to other countries (exports) and what it buys from them (imports).

In simple words: Aggregate demand is the total amount of money businesses expect to get from selling their products. It includes what people spend, what businesses invest, government spending, and trade with other countries.

🎯 Exam Tip: Clearly define aggregate demand as total spending and list its four standard components (C+I+G+(X-M)) to score full marks.

 

Question 32. Explain aggregate supply with the help of a diagram.
Answer: Aggregate supply refers to the total amount of goods and services that producers are willing and able to sell at a given price level in an economy. In Keynesian theory, aggregate supply is closely related to employment and the costs of production.
The diagram below illustrates two aggregate supply curves, Z and Z₁, assuming different conditions for money wages.

• The Z₁ curve (the straight line in the diagram) is linear, representing a situation where money wages remain fixed as employment increases.
• The Z curve (the curved line in the diagram) is non-linear and becomes steeper, showing that the wage rate increases with higher levels of employment.
• The slope of the aggregate supply curve reflects the relationship between employment and productivity.
• In reality, the aggregate supply curve often resembles Z, sloping upwards and becoming steeper as full capacity is approached.
• Therefore, the aggregate supply is influenced by the relationship between prices and wages.

The diagram shows that as employment (Nf) rises, expected proceeds (aggregate supply) also increase, up to a point where the curve might become inelastic, indicating full capacity.
In simple words: Aggregate supply is the total of all goods and services made available. The diagram shows how this supply changes with more workers, especially if wages stay the same or go up. As more people are hired, more goods can be made, but eventually, making even more goods becomes harder.

🎯 Exam Tip: When explaining aggregate supply with a diagram, clearly label axes, distinguish between fixed and rising wage scenarios (Z₁ vs. Z), and explain the implications of the curve's slope.

 

Question 33. Write any five differences between classicism and Keynesianism.
Answer:

Keynesianism focuses on the short-run, the role of government, and how demand drives the economy, contrasting with classical long-run, self-regulating market beliefs.
In simple words: Keynesian ideas say the government should help the economy in the short term, and saving too much can be bad. Classical ideas say the economy fixes itself in the long run, and saving is good.

🎯 Exam Tip: For comparing economic theories, use a clear table format, focusing on core differences in views on government intervention, time horizon, and the role of demand/supply.

Part - D

 

Question 34. Describe the types of unemployment.
Answer: Here are different types of unemployment:
1. **Cyclical Unemployment:** This happens during a business slowdown or recession. When income and production fall, many people lose their jobs. This type of unemployment can be fixed by increasing public investment or using policies that boost the economy.
2. **Seasonal Unemployment:** This type of unemployment happens only at certain times of the year. For example, workers in agriculture or industries that depend on specific seasons might not have work all year round.
3. **Frictional Unemployment:** This occurs because there is a temporary mismatch between the available jobs and the workers looking for jobs. It is like a short-term pause as people move between jobs.
4. **Educated Unemployment:** This happens when educated individuals cannot find suitable jobs, or they are hired for jobs that do not match their skills and qualifications. They might be underemployed or unemployed.
5. **Technical Unemployment:** When new, advanced technology is used, it often needs fewer workers. This switch to capital-intensive methods leads to job losses due as machines replace human labor.
6. **Structural Unemployment:** This is caused by big, lasting changes in the way society or the economy is built. These changes can make some skills or industries less important, leaving workers without jobs.
7. **Disguised Unemployment:** A person is considered disguisedly unemployed if they are working, but their contribution to the total output is very low, or even zero. This means removing them from their job would not reduce the total production.
In simple words: Unemployment can happen in different ways, like when the economy slows down (cyclical), when work is only available during certain seasons (seasonal), when people are between jobs (frictional), when educated people can't find suitable work (educated), when machines replace workers (technical), when the whole economy changes (structural), or when too many people are doing a job that only needs a few (disguised).

🎯 Exam Tip: When describing types of unemployment, always provide a brief explanation for each, and if possible, give a simple example to illustrate the concept clearly.

 

Question 35. Critically explain Say's law of the market.
Answer: Say's Law states that "supply creates its own demand." However, there are several criticisms against this law, especially from Keynesian economics:
1. **Demand and Production Mismatch:** According to Keynes, supply does not automatically create enough demand. This law does not apply when production increases but demand does not rise by the same amount.
2. **Unemployment Persistence:** The automatic adjustment process suggested by Say's Law cannot always remove unemployment. Keynes argued that unemployment can persist and can only be reduced by increasing investment.
3. **Money's Role:** Say's Law assumes money is neutral and only used for transactions. However, people and businesses often hold money for unexpected situations or for future investments, which means not all income is immediately spent.
4. **Overproduction Possibility:** Say's Law claims that overproduction is impossible because supply always creates its own demand. Keynes disagreed, stating that overproduction can happen, leading to unsold goods and economic slowdowns.
5. **Full Employment is Not Guaranteed:** Keynes believed that full employment is a special case, not the norm. He argued that economies often operate with underemployment, meaning some resources, especially labor, are not fully used.
6. **Government Intervention Necessity:** Say's Law suggests no need for government intervention. But Keynes emphasized that in situations of widespread overproduction and mass unemployment, government intervention becomes necessary to restore economic balance.
In simple words: Say's Law says if you make something, someone will buy it. But critics say this is not always true because demand might not keep up with supply, money is not always spent right away, and sometimes there's too much production. Also, Keynes felt that governments need to step in sometimes, especially when many people are out of work.

🎯 Exam Tip: When discussing Say's Law, always mention the core idea and then provide a balanced perspective by including the key criticisms, especially those from Keynesian economics, to show a complete understanding.

 

Question 36. Narrate the equilibrium between ADF and ASF with a diagram.
Answer: In Keynes' theory of employment, we can understand the balance between Aggregate Demand Function (ADF) and Aggregate Supply Function (ASF) by looking at a simple economy with two main parts: households and firms. We assume that the consumption pattern is linear and planned investment happens on its own.

In the diagram below, the Aggregate Demand (AD) and Aggregate Supply (AS) curves meet at point E. This point E shows the equilibrium level, where the level of employment is ON₀.
At an employment level of ON₁, the aggregate supply is N₁R₁. However, to reach the expected profit level M₁R₁, businesses will hire more workers. The tendency to hire more labor continues until the equilibrium point E is reached.
If employment goes beyond ON₀, the AD curve falls below the AS curve, meaning businesses would face losses. Therefore, ON₀ is the ideal level of employment. This "effective demand" is very important for setting the equilibrium level of output in a capitalist economy according to Keynes.
It is important to note that the equilibrium employment level (ON₀) might not always be the full employment level (N₁) for everyone who wants to work. The difference between ON₀ and N₁ represents the level of unemployment. Therefore, effective demand is crucial for explaining unemployment below full capacity.
In simple words: The economy finds its balance where the total demand for goods and services (Aggregate Demand) meets the total supply of goods and services (Aggregate Supply). This meeting point sets how many people will be employed. Sometimes, this balance might mean not everyone who wants to work can find a job.

🎯 Exam Tip: When explaining equilibrium with a diagram, clearly label all axes and curves, mark the equilibrium point, and explain what happens at points before and after equilibrium to demonstrate the stability of the equilibrium.

 

Question 37. Explain the differences between classical theory and Keynes theory:
Answer: Here are the key differences between the classical economic theory and Keynesian theory:

In simple words: Classical theory thinks the economy always fixes itself in the long run and needs no government help, while Keynesian theory believes government action is sometimes needed, especially in the short run, to deal with problems like unemployment.

🎯 Exam Tip: When comparing economic theories, use a clear table format to highlight contrasting features like the role of government, the importance of saving, and the approach to equilibrium. This helps in scoring full marks.

II. Choose the correct pair

 

Question 1.
a) Long-run - Full employment
b) Market Economy - Government control
c) Keynes theory - Long run
d) Structural unemployment - Agriculture
Answer: (a) Long-run - Full employment
In simple words: The correct pair is "Long-run - Full employment" because classical economists believed that in the long run, market forces would naturally lead to full employment. The other options are incorrect pairs based on common economic understanding.

🎯 Exam Tip: For "choose the correct pair" questions, evaluate each option independently based on your knowledge of economic principles. Only one pair will align perfectly with established theory.

a) C - Private savings
b) S - Consumption Expenditure
c) T - Net tax payments
d) Rf - Tax rate
Answer: (c) T - Net tax payments
In simple words: In economics, "T" often represents net tax payments. The other symbols usually stand for different concepts: "C" is consumption, "S" is savings, and "Rf" is typically a risk-free rate, not just a tax rate.

🎯 Exam Tip: Pay close attention to standard economic notations. Knowing what each letter or symbol commonly represents can quickly help you identify the correct pair.

 

Question 3.
a) Effective demand - Percapita Income
b) Equilibrium - Full employment
c) Aggregate supply function - Elastic
d) Say's law - Underemployment
Answer: (b) Equilibrium - Full employment
In simple words: In classical economics, equilibrium is typically associated with full employment. The other pairs have mismatches, like effective demand not directly being per capita income, aggregate supply function not always being elastic, and Say's law not being directly linked to underemployment.

🎯 Exam Tip: Remember that "equilibrium" in classical theory implies full resource utilization, including full employment. This foundational concept helps differentiate correct from incorrect pairs.

 

III. Choose the incorrect pair

 

Question 1.
a) Price Mechanism- Lassiez faire Economy
b) J.B. Say - Classical theory
c) J.M. Keynes - Macro Economics
d) Law of the market - Underemployment
Answer: (d) Law of the market - Underemployment
In simple words: The "Law of the market" (Say's Law) suggests that markets automatically clear and lead to full employment, so pairing it with "underemployment" is incorrect. The other pairs accurately link concepts with their associated economic ideas or economists.

🎯 Exam Tip: When choosing the incorrect pair, actively look for a statement that contradicts a fundamental principle or a known association. Say's Law and underemployment are opposites in their implications.

 

Question 2.
a) Business cycle
b) Seasonal unemployment
c) New technology
d) Disguised unemployment
Answer: (a) Business cycle
In simple words: Seasonal, new technology, and disguised unemployment are specific types of unemployment. A business cycle, however, is a broader economic fluctuation that *causes* cyclical unemployment, but it is not a *type* of unemployment itself. So, "business cycle" is the odd one out here.

🎯 Exam Tip: Understand the difference between causes or contexts of unemployment (like a business cycle) and the specific classifications of unemployment (like seasonal or technological). This distinction is key to identifying the odd one out.

 

Question 3.
a) Aggregate supply price - Income
b) Consumption function - Straight line
c) Keynes theory - Induced Investment
d) Equilibrium - Underemployment
Answer: (d) Equilibrium - Underemployment
In simple words: According to Keynes, an economy can be in equilibrium even with underemployment, not just full employment. So, pairing "equilibrium" with "underemployment" is a correct statement from a Keynesian perspective, but if the question implies a classical view or a general context, it might be seen as incorrect. Given the context of "incorrect pair," the question is likely referring to the classical view where equilibrium implies full employment. Therefore, in classical terms, this is an incorrect pairing.

🎯 Exam Tip: Be careful with the context of "equilibrium." In classical economics, equilibrium means full employment. In Keynesian economics, equilibrium can occur at less than full employment. The question's intent (classical vs. Keynesian) is crucial for correct interpretation.

 

IV. Choose the correct statement

 

Question 1.
a) Equilibrium level of employment refers to full employment.
b) According to Say's law demand creates its own supply.
c) Adam Smith published his books "An enquiry into the nature and causes of the wealth of nations" in the year 1776.
d) Technical unemployment is due to drastic change in the structure of the society
Answer: (c) Adam Smith published his books "An enquiry into the nature and causes of wealth of nations" in the year 1776.
In simple words: This statement is correct because Adam Smith's famous book "The Wealth of Nations" was indeed published in 1776. The other statements contain inaccuracies: equilibrium does not always mean full employment (Keynesian view), Say's law states supply creates its own demand (not the other way around), and technical unemployment is due to new technology, not societal structure changes (which cause structural unemployment).

🎯 Exam Tip: For historical facts like publication dates or specific statements from economists, precise recall is important. For economic principles, distinguish between different theories (classical vs. Keynesian) when evaluating statements.

 

Question 2. Assumptions of Say's law of markets :
a) Existence of underemployment.
b) Money is a prominent force in the economy.
c) Government interference is a must.
d) Long-run analysis.
Answer: (d) Long-run analysis.
In simple words: Say's Law mainly focuses on how the economy works in the long run. It assumes full employment, money is neutral, and there is no need for government intervention. Therefore, options (a), (b), and (c) contradict the assumptions of Say's law.

🎯 Exam Tip: When identifying assumptions of a theory, remember its core tenets. Say's Law assumes a self-adjusting economy over the long run, with no significant role for money or government intervention, and a tendency towards full employment.

 

Question 3.
a) Keynes supported the ideas of classical Economists.
b) An increase in the aggregate effective demand would increase the level of employment.
c) Effective Demand is less than National income.
d) Price refers to the cost of production.
Answer: (b) An increase in the aggregate effective demand would increase the level of employment.
In simple words: This statement is correct according to Keynesian theory, where boosting overall demand helps create more jobs. Keynes did not support classical ideas; effective demand can be equal to or less than national income depending on the context, and price is not just the cost of production but includes profit.

🎯 Exam Tip: A key takeaway from Keynesian economics is the strong link between effective demand and employment levels. Higher demand encourages firms to produce more and hire more workers.

 

V. Choose the incorrect statement

 

Question 1.
a) Keynes defines full employment as the absence of involuntary unemployment.
b) Full employment generally refers to the full employment of labour force of a country.
c) In developed countries the unemployment is purely structural.
d) Disguised unemployment occurs when more people are than what is actually required.
Answer: (c) In developed countries the unemployment is purely structural.
In simple words: This statement is incorrect. While structural unemployment is present in developed countries, they also experience other types like cyclical or frictional unemployment. It is rarely "purely" structural.

🎯 Exam Tip: Remember that real economies, even developed ones, face various forms of unemployment. It's rare for unemployment to be solely of one type. "Purely" or "always" are often red flags in economic statements.

 

Question 2.
a) In Disguised unemployment and seasonal unemployment are seen in rural areas
b) Due to Globalisation, a large number of people move from rural areas to urban areas.
c) Cyclical unemployment can be cured by public investment or expansionary monetary policy.
d) Seasonal unemployment occurs during certain seasons of the year.
Answer: (b) Due to Globalisation, a large number of people move from rural areas to urban areas.
In simple words: This statement is incorrect as rural-urban migration is influenced by many factors like economic opportunities and social services, not just globalization. The other statements are correct descriptions of their respective economic phenomena.

🎯 Exam Tip: Analyze cause-and-effect relationships carefully. While globalization might play a role, attributing large-scale rural-urban migration solely to it oversimplifies a complex socio-economic trend.

 

Question 3.
a) In disguised unemployment marginal productivity of labour is positive.
b) Laissez-faire is a situation found in Market Economy.
c) According to J.B.Say "supply creates its own demand"
d) Aggregate supply curve is inelastic.
Answer: (a) In disguised unemployment marginal productivity of labour is positive.
In simple words: This statement is incorrect because in disguised unemployment, the additional output from one more worker (marginal productivity) is zero or even negative. The other statements are generally true in economic theory.

🎯 Exam Tip: A core characteristic of disguised unemployment is that the marginal productivity of labor is zero or negligible. This means adding or removing a worker does not significantly change total output.

 

VI. Pick the odd one out:

 

Question 1. The components of Aggregate supply are
a) Total Expenditure
b) Private savings
c) Net tax payments
d) Transfer payments to the foreigners
Answer: (a) Total Expenditure
In simple words: "Total Expenditure" is a component of Aggregate Demand, not Aggregate Supply. The other options - private savings, net tax payments, and transfer payments to foreigners - are indeed components of Aggregate Supply.

🎯 Exam Tip: Clearly differentiate between components of Aggregate Demand (consumption, investment, government spending, net exports) and Aggregate Supply (consumption, savings, taxes, transfers) to avoid confusion.

 

Question 2. The components of Aggregate Demand are
a) Consumption demand
b) Investment demand
c) Government expenditure
d) Net Import
Answer: (d) Net Import
In simple words: "Net Import" is part of Net Exports, which is a component of Aggregate Demand (Exports - Imports). However, consumption demand, investment demand, and government expenditure are direct components of aggregate demand. Net Import itself is not a direct positive component, but rather subtracts from Aggregate Demand. So it is the odd one out if we consider positive contributions.

🎯 Exam Tip: Remember the basic formula for Aggregate Demand: \( AD = C + I + G + (X - M) \). While imports (M) are involved, "Net Import" isn't usually listed as a direct positive component in the same way C, I, and G are.

 

VII. Analyse the reason:

 

Question 1. Assertion (A): Aggregate supply is equal to the value of the national product. Reason (R): Aggregate supply refers to the value of the total output of goods and services produced in an economy in a year.
a) Assertion (A) and Reason (R) both are true and (R) is the correct explanation of (A)
Answer: (a) Assertion (A) and Reason (R) both are true and (R) is the correct explanation of (A)
In simple words: Both statements are true, and the reason correctly explains the assertion. Aggregate supply is indeed the total value of all goods and services produced in an economy over a year, which is essentially the national product.

🎯 Exam Tip: For Assertion-Reason questions, first determine if each statement is true. Then, check if the reason logically explains the assertion. Use "because" between them to test the connection.

 

Question 2. Assertion (A): Supply creates its own demand. Reason (R): Each product produced in the economy creates demand equal to its value in the market.
a) Assertion (A) and Reason (R) both are true and (R) is the correct explanation of (A)
Answer: (a) Assertion (A) and Reason (R) both are true and (R) is the correct explanation of (A)
In simple words: Both statements are true and the reason explains the assertion. This is the core idea of Say's Law, where the act of production generates income, which then funds an equivalent amount of spending, meaning supply generates its own demand.

🎯 Exam Tip: Understand Say's Law's mechanism: production leads to income, which in turn leads to spending. This circular flow is the basis for the assertion-reason connection.

 

Question 3. Assertion (A) : Seasonal unemployment occurs during certain seasons of the year. Reason (R): Seasonal unemployment exists during the downturn phase of the trade cycle in the economy.
c) Assertion (A) is true, Reason (R) is false Options.
Answer: (c) Assertion (A) is true, Reason (R) is false.
In simple words: The assertion is true because seasonal unemployment happens in specific seasons. However, the reason is false because unemployment during a trade cycle downturn is called cyclical unemployment, not seasonal unemployment.

🎯 Exam Tip: Distinguish between different types of unemployment. Seasonal unemployment is tied to specific times of the year, while cyclical unemployment is linked to the ups and downs of the economy (business cycles).

 

Question 4. Assertion (A): Seasonal unemployment occurs during certain seasons of the year. Reason (R): Seasonal unemployment exists during the downturn phase of the trade cycle in the economy.
Options:
a)Assertion (A) and Reason (R) both are true and (R) is the correct explanation of (A).
b) Assertion (A) and Reason (R) both are true, but (R) is not the correct, explanation of (A).
c) Assertion (A) is true, Reason (R) is false.
d) Both (A) and (R) are false.
Answer: (c) Assertion (A) is true, Reason (R) is false.
In simple words: The first statement is correct as seasonal unemployment is about specific times of the year. The second statement is wrong because unemployment during an economic downturn is cyclical, not seasonal.

🎯 Exam Tip: Always verify both the assertion and the reason independently. Even if an assertion is true, the reason might be false or simply not explain the assertion correctly.

 

VIII. Choose the best Answer

 

Question 1. Who is one of the greatest and most influential economists?
(a) J.M. Keynes
(b) Adam Smith
(c) Marshall
(d) Simon Kuznets
Answer: (a) J.M. Keynes
In simple words: John Maynard Keynes is widely considered one of the most important economists of the 20th century, especially for his ideas on government intervention and managing recessions.

🎯 Exam Tip: Recognize key figures in economics and their major contributions. Keynes's influence on macroeconomics is immense and undeniable.

 

Question 2. Aggregate demand can be expressed as
a) AD = C + G + I + (M-X)
b) AD = I + G + C + (X - M)
c) AD = C + I + G + (X - M)
d) AD = C + I + G +(x - M)
Answer: (c) AD = C + I + G + (X - M)
In simple words: Aggregate Demand is the total spending in an economy, calculated by adding Consumption (C), Investment (I), Government spending (G), and Net Exports (Exports (X) minus Imports (M)). This formula covers all the main parts of spending.

🎯 Exam Tip: Memorize the formula for Aggregate Demand. The order of C, I, and G does not matter due to addition, but net exports must be (X-M), not (M-X).

 

Question 3. The total stock of money circulating in an Economy is called-
(a) Money
(b) Capital
(c) Money Supply
(d) Finance
Answer: (c) Money Supply
In simple words: The total amount of money available in an economy at a specific time is called the money supply. This includes physical currency and bank deposits.

🎯 Exam Tip: Understand that "money" is a general term, but "money supply" specifically refers to the measurable amount of money in circulation within an economy.

 

Question 4. Capital intensive technology and innovations lead to ............ Unemployment.
a) Structural
b) Technical
c) Seasonal
d) Disguised
Answer: (b) Technical
In simple words: When new technologies replace human workers, it leads to technical unemployment. This happens as machines and advanced methods take over tasks previously done by people.

🎯 Exam Tip: Link "technology" and "innovation" directly to "technical unemployment." This is a straightforward cause-and-effect relationship in economics.

 

Question 5. How many components are there in the aggregate supply
a) 3
b) 4
c) 1
d) 2
Answer: (b) 4
In simple words: Aggregate supply has four main components: consumption, savings, taxes, and transfers to foreigners. These represent how the national income is used.

🎯 Exam Tip: Remember the four components of aggregate supply: Consumption (C), Savings (S), Taxes (T), and Net Transfers (Rf). Each of these reflects a different use of income.

 

Question 6. ............ is an increasing function of the level of employment -
(a) Aggregate supply function
(b) Aggregate demand function
(c) Aggregate consumption function
(d) Aggregate consumption expenditure
Answer: (a) Aggregate supply function
In simple words: The aggregate supply function shows that as more people are employed, the total output and thus the aggregate supply of goods and services in the economy will increase. This means supply goes up as employment rises.

🎯 Exam Tip: Understand that the aggregate supply curve generally slopes upwards in the short run, meaning more employment leads to higher output and thus higher aggregate supply.

 

Question 7. Keynes defines full employment as the absence of ............ unemployment.
a) Structural
b) Involuntary
c) Seasonal
d) Voluntary
Answer: (b) Involuntary
In simple words: According to Keynes, full employment means that everyone who is willing and able to work at the current wages can find a job. So, it's the absence of involuntary unemployment, where people want to work but cannot find it.

🎯 Exam Tip: Keynes distinguished between voluntary unemployment (people choosing not to work) and involuntary unemployment (people wanting to work but unable to find a job). Full employment, for Keynes, meant the elimination of the latter.

 

Question 9. Adam Smith published his book 'An enquiry into the Nature and Causes of the Wealth of Nations" in '.
(a) 1767
(b) 1776
(c) 1676
(d) 1176
Answer: (b) 1776
In simple words: Adam Smith's famous book, which talks about how countries get rich, came out in the year 1776. This book is a very important part of economics.

🎯 Exam Tip: Knowing the publication dates of foundational economic texts helps place theories in historical context and shows a deeper understanding.

 

Question 10. Frictional unemployment another name is called –
(a) Educated unemployment
(b) Seasonal unemployment
(c) Temporary unemployment
(d) Technical unemployment
Answer: (c) Temporary unemployment
In simple words: Frictional unemployment is like a short break between jobs, so it's often called temporary unemployment. It happens when people are moving from one job to another.

🎯 Exam Tip: Understand that frictional unemployment is usually short-term and is a natural part of a dynamic economy, unlike other types that might be longer-lasting.

 

IX. Answer the following questions (2 Marks)

 

Question 1. Write two approaches of the equilibrium level of Income in Keynesian theory?
Answer: In Keynesian theory, there are two main ways to find the equilibrium level of income. These are the Aggregate Demand-Aggregate Supply approach and the Saving-Investment approach. Both methods lead to the same equilibrium point in the economy.
In simple words: Keynes found economic balance using two methods: matching total demand with total supply, or matching how much people save with how much is invested.

🎯 Exam Tip: Remember these two core approaches as they are fundamental to understanding Keynesian economics and how income equilibrium is determined.

 

Question 2. What is marginal propensity to consume?
Answer: Marginal propensity to consume (MPC) shows how much of an extra unit of income a person will spend on consumption. For example, if someone gets one extra rupee, MPC tells us what fraction of that rupee they will spend. It helps us understand spending habits.
In simple words: Marginal propensity to consume means how much more money people spend when they get a little extra income.

🎯 Exam Tip: Always define MPC clearly and note that it's a ratio (change in consumption / change in income), usually a value between 0 and 1.

 

Question 3. Define "Marginal propensity to consume”?
Answer: Marginal Propensity to Consume (MPC) is the extra amount spent on consumption when an additional unit of income is received. It indicates the proportion of additional income that individuals choose to spend rather than save. This concept is crucial for understanding how changes in income affect overall spending in an economy.
In simple words: Marginal Propensity to Consume is how much more people spend when they get more money.

🎯 Exam Tip: When defining MPC, explicitly mention it as the "additional consumption" from an "additional unit of income."

 

Question 4. What is Underemployment?
Answer: Underemployment happens when resources, especially people, are not used to their full potential in production. This means someone might be working fewer hours than they want, or doing a job that doesn't use their skills properly. It indicates an inefficient use of the workforce.
In simple words: Underemployment is when workers are not used fully, either by working too few hours or doing jobs below their skill level.

🎯 Exam Tip: Distinguish underemployment from unemployment; underemployed people are working, just not optimally.

 

Question 4. Write the types of unemployment?
Answer: There are several types of unemployment, each with different causes:
1. Cyclical Unemployment
2. Frictional Unemployment
3. Technical Unemployment
4. Disguised Unemployment
5. Seasonal Unemployment
6. Educated Unemployment
7. Structural Unemployment. Each type reflects a different challenge in the labor market.
In simple words: There are many types of joblessness, like when jobs disappear in bad times, or people are between jobs, or new machines take over tasks.

🎯 Exam Tip: When asked to list types, ensure you provide distinct categories. Briefly explaining each type would earn extra points in a descriptive answer.

 

Question 6. State J.B.Say's law of Market.
Answer: J.B. Say's law of Market states that "Supply creates its own demand." This means that when goods and services are produced, they generate enough income for people to buy those goods and services. It implies that there will always be enough demand to match the supply.
In simple words: Say's law says that making things creates enough money for those things to be bought.

🎯 Exam Tip: Remember the core quote "Supply creates its own demand" as it's the defining characteristic of Say's Law.

 

X. Answer the following questions (3 Marks)

 

Question 1. Mention the types of Unemployment.
Answer: There are seven main types of unemployment:
1. Cyclical Unemployment: This happens when there's a fall in overall demand during a recession, causing businesses to cut jobs.
2. Frictional Unemployment: This is short-term joblessness when people are temporarily moving between jobs or searching for new ones.
3. Technical Unemployment: This occurs when new technologies replace human labor, reducing the need for workers in certain industries.
4. Disguised Unemployment: This is when more people are working than what is actually needed for the production, so some workers' removal would not affect output.
5. Seasonal Unemployment: This affects workers in industries that operate only during specific times of the year, like agriculture or tourism.
6. Educated Unemployment: This refers to educated individuals who are unable to find suitable jobs that match their qualifications.
7. Structural Unemployment: This arises from a mismatch between the skills workers have and the skills needed for available jobs, often due to long-term changes in the economy.
In simple words: Unemployment can be cyclical (due to bad economy), frictional (between jobs), technical (due to machines), disguised (too many workers for the job), seasonal (only some months), educated (skills don't match jobs), or structural (big changes in industry).

🎯 Exam Tip: For each type of unemployment, try to associate a key characteristic or cause (e.g., "cyclical = recession", "frictional = job search").

 

Question 2. Aggregate Supply Function meaning and components?
Answer: The Aggregate Supply (AS) function shows the relationship between the total output produced in an economy and the level of employment. It is generally an increasing function of employment, meaning more workers lead to more output. In simpler terms, it represents the total value of goods and services that producers are willing to offer for sale in an economy during a given period. The components of aggregate supply are:
1. Aggregate (desired) consumption expenditure (C)
2. Aggregate (desired) private savings (S)
3. Net tax payments (T) (This includes total tax payments to the government minus any transfer payments, subsidies, and interest payments the government makes.)
4. Personal (desired) transfer payments to foreigners (Rf) (These are things like donations made to international relief efforts).
In simple words: Aggregate Supply shows how much an economy can produce based on how many people are working. It includes money spent on goods, savings, taxes, and money sent abroad.

🎯 Exam Tip: Clearly define aggregate supply as the total value of goods and services, and list its components accurately. Remember that the AS curve typically slopes upwards initially before becoming vertical at full employment.

 

Question 3. What is the marginal Efficiency of Capital?
Answer: The Marginal Efficiency of Capital (MEC) is the expected rate of return from investing in a new capital asset, like a machine or a factory, over its lifetime. It compares the expected future profits from that investment with its current cost. MEC helps businesses decide whether to invest more.
MEC depends on two main factors: the prospective yield (the expected profits) from a capital asset, and its supply price (the cost to produce or acquire that asset).
In simple words: Marginal Efficiency of Capital is how much profit a company expects to make from buying a new machine or building, compared to its cost.

🎯 Exam Tip: Distinguish MEC as an "expected" rate of return, emphasizing its forward-looking nature in investment decisions.

 

Question 4. Name the Motives of Liquidity Preference.
Answer: In economics, liquidity preference refers to people's desire to hold money in a liquid form (cash) rather than investing it or holding it in less liquid assets. There are three main reasons, or motives, for this preference:
1. Transaction Motive: People hold money to pay for their everyday expenses and transactions. This is for regular buying and selling.
2. Precautionary Motive: People keep money aside for unexpected needs or emergencies. This acts as a safety net for future uncertainties.
3. Speculative Motive: People hold money to take advantage of future changes in the price of assets, like bonds. They might wait for bond prices to fall before buying, or interest rates to rise.
In simple words: People like to keep cash for three reasons: to buy things daily (transaction), for sudden problems (precautionary), and to wait for better investment deals (speculative).

🎯 Exam Tip: Remember the three motives for liquidity preference and be able to briefly describe each one with an example.
