RBSE Class 12 Economics Chapter 22 Multiple Choice Questions
Question 1. Deficient Demand is a situation when :
(a) AD < AS
(b) AD > AS
(c) AD = AS
(d) AD ≠ AS
Answer: (a) AD < AS
In simple words: Deficient demand happens when the total demand for goods and services in the economy is less than the total supply. This means there are more goods than people want to buy.
🎯 Exam Tip: Clearly define AD (Aggregate Demand) and AS (Aggregate Supply) in your mind before answering questions about their relationship to demand conditions.
Question 3. Fiscal measures during deflation are :
(a) Increase in taxation
(b) Increase in Public Expenditure
(c) Reduction in Public Expenditure
(d) Increase in prices
Answer: (b) Increase in Public Expenditure
In simple words: When the economy is slowing down and prices are falling (deflation), the government often spends more money. This extra spending helps to boost demand and economic activity.
🎯 Exam Tip: Remember that fiscal measures involve government spending and taxation; during deflation, the goal is to stimulate the economy.
Question 4. To control inflation, the measure adopted in monetary policy is :
(a) Increase in bank rate
(b) Reduction in taxation
(c) Increase in public expenditure
(d) Reduction in bank rate
Answer: (a) Increase in bank rate
In simple words: To slow down rising prices (inflation), the central bank raises the bank rate. This makes borrowing money more expensive, which reduces spending and helps to cool down the economy.
🎯 Exam Tip: Monetary policy focuses on controlling money supply and credit through tools like bank rates, while fiscal policy uses government spending and taxes.
Question 5. The aggregate supply curve in the figure reflects which concept?
(a) Keynesian
(b) Classical
(c) Moneterism
(d) Ratex
Answer: (b) Classical
In simple words: The diagram shows a vertical aggregate supply curve, which means that supply does not change no matter what the price is. This is a key idea in classical economics. This model assumes that the economy always operates at full employment.
🎯 Exam Tip: A vertical aggregate supply curve always represents the classical view of an economy at full capacity, where output is fixed regardless of price level changes.
RBSE Class 12 Economics Chapter 22 Very Short Answer Type Questions
Question 1. Define Aggregate Demand.
Answer: Aggregate Demand is the total demand for all goods and services produced in an economy over a specific period. It is calculated by adding up all consumption expenditure and investment expenditure. This represents the total spending by all sectors of an economy.
In simple words: Aggregate Demand is the total amount of everything that people, businesses, and the government want to buy in a country.
🎯 Exam Tip: When defining Aggregate Demand, always mention that it includes all goods and services in the economy, not just one type.
Question 2. Write down four components of Aggregate Demand.
Answer: The four main parts of Aggregate Demand are:
1. Consumption Expenditure
2. Investment Expenditure
3. Government Expenditure
4. Net Exports (which is Exports minus Imports)
These components show how different parts of the economy contribute to total demand.
In simple words: The four things that make up total demand in an economy are what people spend, what businesses invest, what the government spends, and the difference between what we sell to other countries and what we buy from them.
🎯 Exam Tip: Remember the four main components (Consumption, Investment, Government Spending, Net Exports) as these are fundamental to understanding macroeconomic models.
Question. What is Macro Economic Equilibrium?
Answer: Macroeconomic equilibrium is an economic state where the total quantity of goods and services demanded (Aggregate Demand) equals the total quantity supplied (Aggregate Supply). This balance shows the actual short-term equilibrium state of an economy. At this point, there is no tendency for the overall price level or output to change.
In simple words: Macroeconomic equilibrium is when the total amount of goods and services people want to buy in a country is exactly equal to the total amount of goods and services businesses can make.
🎯 Exam Tip: Always specify that macroeconomic equilibrium occurs when Aggregate Demand (AD) equals Aggregate Supply (AS) to show a complete understanding.
Question 5. Define depression.
Answer: Depression is a severe and prolonged downturn in economic activity. It is marked by a significant and widespread reduction in various economic activities like the production of goods and services, employment levels, people's income, overall demand, and the general price level. This period is often characterized by very low confidence and high unemployment.
In simple words: Depression is a very bad time for the economy when there is much less production, many people lose jobs, and everything slows down a lot.
🎯 Exam Tip: Distinguish depression from recession by emphasizing its "severe" and "prolonged" nature, impacting multiple economic indicators significantly.
RBSE Class 12 Economics Chapter 22 Short Answer Type Questions
Question 1. Explain Deficient Demand.
Answer: Deficient Demand happens when the total demand for goods and services in an economy (Aggregate Demand) is less than what the economy can produce at full employment (Aggregate Supply). In this situation, producers reduce their output because they cannot sell all the goods they have made. This leads to a large stock of unsold goods, which then causes prices to fall. Lower prices further discourage production and investment.
In simple words: Deficient demand is when people do not want to buy as much as businesses can make. This makes businesses produce less, leading to lower prices and unsold goods.
🎯 Exam Tip: When explaining deficient demand, highlight the chain reaction: AD < AS \( \implies \) reduced production \( \implies \) unsold stock \( \implies \) falling prices.
Question 2. What do you mean by excess demand ?
Answer: Excess demand occurs when the total demand for goods and services (Aggregate Demand) is greater than what the economy can produce (Aggregate Supply) at full employment. This strong demand encourages producers to make more goods, but since the economy is already at full capacity, this primarily leads to an increase in the cost of production factors. This rise in costs eventually causes the prices of goods to go up, leading to inflation. People want to buy more than what is available.
In simple words: Excess demand is when people want to buy more goods and services than what is available. This makes producers try to make more, which drives up costs and then prices.
🎯 Exam Tip: For excess demand, focus on the cause (AD > AS) and the effect (increased factor costs leading to price rises/inflation).
Question 3. What is monetary policy ?
Answer: Monetary policy is a set of actions taken by the central bank of a country to manage the money supply and credit conditions in an economy. The main goals are to control inflation, stabilize economic growth, and achieve other economic policy objectives. This involves managing things like interest rates and the availability of credit.
In simple words: Monetary policy is how the central bank controls the amount of money in the economy and how easy it is to borrow, to keep prices stable and help the economy grow.
🎯 Exam Tip: Emphasize that monetary policy is implemented by the central bank and aims to control money supply and credit for economic stability.
Question. What are the instruments of Fiscal Policy?
Answer: The main instruments of fiscal policy are government expenditure and taxation. These tools are used to influence the economy. Government expenditure can be increased or decreased depending on the economic situation, and it includes government transfer payments, current expenses, or capital investments. Taxation involves adjusting tax rates to affect disposable income and spending.
In simple words: Fiscal policy uses two main tools: how much the government spends (like on roads or schools) and how much it collects in taxes from people and businesses.
🎯 Exam Tip: Remember that fiscal policy always involves the government's budget decisions: taxation (revenue) and public expenditure (spending).
Question 5. What measures of monetary policy are adopted during inflation?
Answer: During times of inflation, the central bank adopts several monetary policy measures to control rising prices and reduce excess demand. These measures include:
1. Increasing the bank rate, which makes borrowing more expensive.
2. Selling government securities in the open market to reduce money supply.
3. Raising the Cash Reserve Ratio (CRR), which reduces the amount of money banks can lend.
4. Increasing the selective credit limit and controlling consumer credit to limit borrowing for specific purposes.
5. Demonetisation of currency can also be considered in extreme cases.
All these actions aim to reduce the amount of money flowing in the economy, thereby lowering demand and controlling prices.
In simple words: To stop prices from rising too fast during inflation, the central bank makes it harder and more costly to borrow money. They raise interest rates and reduce the money available for lending.
🎯 Exam Tip: Focus on how each monetary tool (bank rate, open market operations, CRR, credit limits) works to reduce money supply and curb inflation.
RBSE Class 12 Economics Chapter 22 Essay Type Questions
Question 1. Explain in detail the AS and AD model.
Answer: The Aggregate Supply (AS) and Aggregate Demand (AD) model helps us understand how an economy reaches short-term equilibrium. This equilibrium shows the actual state of the economy, where real GDP (Gross Domestic Product) fluctuates around its potential level. The effectiveness of both monetary and fiscal policies can be understood through this model.
If the price level is OP\(_{0}\), then Aggregate Demand (AD) equals Aggregate Supply (AS) at point E. This is the equilibrium point where the economy is stable. If the price level drops to OP\(_{1}\), Aggregate Demand is less than Aggregate Supply (AD < AS), creating a situation of "Deficient Demand" (represented by point A on the AD curve and C on the AS curve). This excess supply leads to producers reducing production. They can't sell their output due to low demand. As a result, a lot of unsold goods build up, pushing market prices down until they reach the previous equilibrium level of OP\(_{0}\) (where income and price are balanced).
Conversely, if the price level rises to OP\(_{2}\), Aggregate Demand is greater than Aggregate Supply (AD > AS). This situation is called "Excess Demand" (represented by point B on the AD curve and D on the AS curve). High demand encourages producers to increase production. However, this also increases the demand for resources (factors of production), which drives up their costs. These higher factor costs then lead to an increase in the prices of goods, and the economy eventually returns to equilibrium at price OP\(_{0}\). In the short run, money wages usually stay the same, and potential GDP can be higher or lower than the actual GDP. In the long run, the Aggregate Demand curve meets the long-run Aggregate Supply curve.
In simple words: The AD-AS model shows how the total demand and total supply of an economy meet to find a balance. If demand is too low, prices fall, and if demand is too high, prices rise, eventually returning to a stable point. This helps understand how government actions affect the economy.🎯 Exam Tip: When drawing and explaining the AD-AS model, clearly label the axes, curves, equilibrium point, and the areas of deficient and excess demand to score full marks.
Question 2. Differentiate between Keynesian and Classical aggregate supply curve with the help of diagram.
Answer: Aggregate Supply represents the total production of goods and services by firms at different possible price levels, assuming other factors remain constant. The Keynesian and Classical theories have different views on the shape of the aggregate supply curve, mainly due to their assumptions about employment and resource utilization.
| Classical Aggregate Supply | Keynesian Aggregate Supply |
|---|---|
The theories of classical economists are based on the assumption of full employment. This means they believe all available resources, including labor, are fully utilized. Therefore, according to classical theory, the aggregate supply curve is a perfectly inelastic vertical straight line, as shown in Figure 1. This vertical curve indicates that the economy's output is fixed at its full employment level (Y\(_{1}\)), regardless of price changes.
On the other hand, the Keynesian Aggregate Supply curve is different. It is typically shown in three phases (Figure 3):
1. **Horizontal Range (PA):** This is called the Keynesian range, representing a period of depression. In this phase, there are many unused resources in the economy. An increase in Aggregate Demand leads only to an increase in production, without any rise in the per-unit cost or prices. This is because businesses can easily use idle resources.
2. **Middle Range (between Y and Y\(_{1}\)):** As Aggregate Demand increases further, the economy moves towards full employment. In this range, both production and the price level increase. Per-unit costs begin to rise because resources become scarcer, pushing up market prices.
3. **Vertical Range (BC):** This is the classical range, which shows the full employment level of resources. Here, the supply curve becomes perfectly inelastic (vertical). Once full capacity is reached, any further increase in Aggregate Demand only leads to higher prices, while the quantity of production remains unchanged because all resources are fully used.
In simple words: Classical economists believe that an economy always produces its maximum output, so supply is fixed. Keynesian economists believe that output can change, and supply can be flat during a downturn, then rise with prices, and finally become fixed at maximum output.🎯 Exam Tip: When differentiating, remember that Classical theory assumes full employment (vertical AS), while Keynesian theory allows for unemployment and has a flatter AS curve at low output levels, becoming vertical at full employment.
Question 3. How can fiscal policy be effectively used at the time of depression?
Answer: During a depression, when there is deficient demand (Aggregate Demand is less than Aggregate Supply), the government can effectively use fiscal policy to stimulate the economy. The main measures include:
1. **Increasing Public Expenditure:** The government raises its spending on various projects like road building, dam construction, and building schools and hospitals. This creates jobs, boosts income, and increases overall demand in the economy.
2. **Reducing Taxes:** Taxes are lowered to increase the disposable income of consumers. With more money in their hands, people are encouraged to spend more, which also helps to increase demand.
These actions are designed to bring the economy back to full employment and stabilize prices. Fiscal policy is generally more successful than monetary policy during a depression because businesses already have large unsold stocks. Even with lower interest rates from monetary policy, they are not motivated to invest more. Thus, government intervention through fiscal policy directly boosts demand and economic activity.
In simple words: During a depression, the government uses fiscal policy by spending more money and cutting taxes. This helps create jobs and gives people more money to spend, which makes the economy start moving again. Monetary policy often doesn't work as well because businesses are not ready to invest even with cheap loans.
🎯 Exam Tip: Highlight that during depression, fiscal policy is preferred because it directly boosts demand and employment through government spending and tax cuts, which monetary policy (lower interest rates) might fail to do due to low business confidence.
Question 4. Explain the policies adopted by government to check inflation.
Answer: To control inflation, the government adopts both monetary and fiscal policy measures. These policies aim to reduce excess demand in the economy.
**Monetary Policy Measures:** The central bank plays a key role by:
1. **Increasing the Bank Rate:** This makes borrowing more expensive for commercial banks, leading to higher lending rates and reduced credit availability.
2. **Selling Securities in Open Market:** This absorbs liquidity from the banking system, reducing the money supply.
3. **Increasing the Reserve Ratio (CRR and SLR):** Banks are required to hold more reserves, leaving less money for lending.
4. **Selective Credit Control:** Imposing stricter limits on credit for specific purposes to curb speculative demand.
5. **Controlling Consumer Credit:** Making it harder to get loans for consumer durables.
6. **Demonetisation of Currency:** In extreme cases, invalidating certain currency notes to reduce black money and excess liquidity.
**Fiscal Policy Measures:** The government also uses its budget to control inflation:
1. **Surplus Budget:** The government aims to spend less than it collects in taxes, creating a surplus to reduce overall demand.
2. **Repayment of Public Debt:** Halting the repayment of public debt to prevent injecting more money into the economy.
By combining these rigid monetary and fiscal policies, the government works to reduce aggregate demand, thereby controlling rising prices and achieving economic stability.
In simple words: To stop inflation, the government and central bank make it harder for people to borrow and spend money. They increase interest rates, sell government bonds, make banks hold more money, and sometimes even change currency. The government also tries to spend less than it earns.
🎯 Exam Tip: When discussing anti-inflationary policies, mention both monetary (central bank actions) and fiscal (government budget actions) measures, and explain how each measure reduces money supply or aggregate demand.

RBSE Class 12 Economics Chapter 22 Multiple-Choice Questions
Question 1. What does AD < AS denote ?
(a) Deficient demand
(b) Excess demand
(c) Zero demand
(d) None of these
Answer: (a) Deficient demand
In simple words: When the total demand in the economy is less than the total supply, it means there is not enough demand, which we call deficient demand.
🎯 Exam Tip: Always remember that "AD < AS" is the clear definition of deficient demand, indicating a shortfall in aggregate spending.
Question 2. Increase in the government expenditure during depression is a solution under which policy :
(a) Monetary Policy
(b) Fiscal Policy
(c) Revenue Policy
(d) None of these
Answer: (b) Fiscal Policy
In simple words: When the government increases its spending to help the economy during a slow period, this action falls under fiscal policy, which uses government budgets to influence the economy.
🎯 Exam Tip: Government expenditure and taxation are the two main tools of fiscal policy, so an increase in government spending directly points to fiscal measures.
Question 3. Fiscal Policy involves :
(a) Government expenditure
(b) Taxes
(c) Public Debt
(d) All of the options
Answer: (d) All of the options

Question 8. Expansionary monetary and fiscal policy is effective in :
(a) Prosperity
(b) Depression
(c) Equilibrium
(d) None of these
Answer: (b) Depression
In simple words: When the economy is in a depression, both the central bank and the government try to boost it by making money more available and by spending more, which are called expansionary policies.
🎯 Exam Tip: Expansionary policies (increasing money supply, reducing taxes, increasing government spending) are used to combat depressions by stimulating economic activity.
Question 9. Which of the following is a direct tax:
(a) Income tax
(b) Asset tax / Property tax

(d) (a) and (b)
Answer: (d) (a) and (b)
In simple words: Direct taxes are paid straight to the government by the person or company who owes them, like income tax and taxes on property or assets.
🎯 Exam Tip: Distinguish direct taxes (income, property) from indirect taxes (sales, customs) by who bears the immediate burden of payment to the government.
RBSE Class 12 Economics Chapter 22 Very Short Answer Type Questions
Question 1. As per classical economists, determination of income is affected through which factors?
Answer: According to classical economists, the determination of income is primarily influenced by real factors such as capital stock and the supply of labor. These physical resources and the workforce available in an economy are used to estimate the production of income. They believed that these real factors determined the economy's productive capacity.
In simple words: Classical economists thought that how much a country earns depends on how much capital (like factories) it has and how many people are working.
🎯 Exam Tip: Remember that classical theory focuses on supply-side, real factors like capital and labor as the determinants of income and output.
Question. When is macro economic equilibrium determined?
Answer: Macroeconomic equilibrium is determined at the point where Aggregate Demand (AD) equals Aggregate Supply (AS). This is the level where the total demand for goods and services in an economy matches the total supply available. At this point, the economy is stable, and there is no pressure for production or prices to change significantly. This reflects a state of balance in the overall economy.
In simple words: The economy finds its balance (equilibrium) when the total amount of things people want to buy is equal to the total amount of things businesses are making.
🎯 Exam Tip: The core condition for macroeconomic equilibrium is always the equality of Aggregate Demand and Aggregate Supply.
Question 4. Which factors are included under Aggregate Demand ?
Answer: The factors included under Aggregate Demand are Consumption Expenditure, Private Investment Expenditure, Government Expenditure on the purchase of goods and services, and Net Exports (which is the difference between exports and imports). These four components represent the total spending by all sectors of the economy. Each factor contributes to the overall demand for goods and services.
In simple words: Aggregate Demand includes what people spend (consumption), what businesses invest, what the government spends on goods and services, and what other countries buy from us minus what we buy from them.
🎯 Exam Tip: List all four standard components of Aggregate Demand (C+I+G+Xn) for a complete answer.
Question 5. What does Aggregate Demand Curve indicate ?
Answer: The Aggregate Demand (AD) curve shows the relationship between the total demand for all goods and services in an economy and the overall general price level. It typically slopes downwards, indicating that as the general price level falls, the quantity of goods and services demanded by consumers, businesses, government, and foreign buyers tends to increase. This is due to effects like the wealth effect, interest rate effect, and exchange rate effect.
In simple words: The Aggregate Demand curve shows how the total amount of things people want to buy changes when prices in the whole country go up or down. Usually, if prices fall, people want to buy more.
🎯 Exam Tip: Remember that the AD curve plots the relationship between the general price level and the total quantity of output demanded in the economy.
Question 6. What is the relation between general price level and Aggregate Production?
Answer: The relation between the general price level and aggregate production (or aggregate supply) can be inverse in the short run but can also be positive or fixed depending on the economic phase. In the Keynesian view, during a depression, production can increase without price changes (horizontal AS). As the economy nears full employment, prices and production both rise. At full employment, production is fixed, and only prices change (vertical AS). This complex relationship highlights how different economic conditions affect supply responses to price changes.
In simple words: How prices and total production are related changes depending on how busy the economy is. Sometimes, more production means higher prices, but sometimes production can go up without prices changing much.
🎯 Exam Tip: Specify whether the relationship is short-run or long-run, and consider both Keynesian (variable output) and Classical (fixed output) perspectives for a comprehensive answer.
Question 7. What will be the effect of price rise on Consumption Expenditure?
Answer: A rise in prices generally causes consumption expenditure to decrease. When prices go up, the real value of people's money falls, meaning they can buy fewer goods and services with the same amount of money. This reduction in purchasing power leads to a decline in their overall consumption spending. Consumers become more cautious and tend to postpone purchases of non-essential items.
In simple words: If prices go up, people can buy less with the same amount of money, so they spend less on goods and services.
🎯 Exam Tip: Explain the "wealth effect": higher prices reduce the real value of wealth, leading to less consumption.
Question 8. What is the effect of price rise on Export and Import?
Answer: When domestic prices rise, it generally makes a country's exports more expensive for foreign buyers, leading to a decrease in exports. At the same time, foreign goods become relatively cheaper compared to domestically produced goods, which causes imports to increase. This dual effect of reduced exports and increased imports negatively impacts the country's net exports and overall aggregate demand. A stronger currency can also contribute to this effect.
In simple words: If prices in a country go up, its products become more expensive for other countries, so it sells less (exports decrease). Also, things from other countries become cheaper, so it buys more (imports increase).
🎯 Exam Tip: Remember that higher domestic prices make exports less competitive and imports more attractive, impacting the trade balance.
Question 9. What is the shape of Aggregate Supply curve in full employment situation?
Answer: In a full employment situation, the Aggregate Supply curve is vertical. This means that at full employment, the economy has utilized all its available resources to their maximum potential. Any increase in aggregate demand will only lead to a rise in prices, without any further increase in the quantity of goods and services supplied. This represents the classical view of a fully optimized economy.
In simple words: When everyone who wants to work has a job and all factories are running at full power (full employment), the total supply curve goes straight up. This means the economy cannot make any more goods, no matter how high prices go.
🎯 Exam Tip: A vertical Aggregate Supply curve always signifies full employment and the economy's maximum potential output, where output is fixed.
Question 11. What can be the other name for horizontal range?
Answer: The other name for the horizontal range of the Aggregate Supply curve is the Keynesian Range. This part of the curve indicates a period of depression or underemployment where there are unused resources in the economy. In this range, output can increase without causing inflation.
In simple words: The horizontal part of the supply curve is also called the Keynesian Range, which means the economy has many unused resources and can make more without prices going up.
🎯 Exam Tip: The Keynesian range is characterized by abundant idle resources, allowing output to expand horizontally without significant price changes.
Question 12. What is the type of vertical range supply curve?
Answer: The vertical range of the supply curve is perfectly inelastic. This means that the quantity supplied does not change at all, regardless of changes in price. This situation occurs when the economy is at its full capacity, using all available resources to produce goods and services. Beyond this point, no more output can be created, even if prices rise significantly.
In simple words: The vertical part of the supply curve means it's perfectly inelastic, which means no matter how much the price changes, the amount supplied stays the same because the economy is already making as much as it possibly can.
🎯 Exam Tip: Perfect inelasticity in the vertical range implies that the economy has reached its maximum productive capacity, making output unresponsive to price changes.
Question 13. What is the meaning of Excess Demand ?
Answer: Excess Demand means that the total demand for goods and services (Aggregate Demand) in an economy is greater than the total supply (Aggregate Supply) available at the full employment level. This situation typically leads to inflationary pressures as consumers compete for limited goods, pushing up prices. It signifies that the economy is trying to produce beyond its sustainable capacity.
In simple words: Excess demand is when people want to buy more goods and services than the country can actually make, which causes prices to go up.
🎯 Exam Tip: Define excess demand by directly comparing Aggregate Demand (AD) and Aggregate Supply (AS) (AD > AS), and linking it to inflation.
Question 14. What is Deficient Demand?
Answer: Deficient Demand occurs when the total demand for goods and services (Aggregate Demand) in an economy is less than the total supply (Aggregate Supply) at the full employment level. This situation typically results in a slowdown of economic activity, leading to falling prices, unsold inventories, and unemployment. It indicates that the economy is not using all its productive capacity.
In simple words: Deficient demand is when people want to buy less than what businesses can produce, which leads to slow economic activity and falling prices.
🎯 Exam Tip: Clearly state that deficient demand means Aggregate Demand (AD) is less than Aggregate Supply (AS) (AD < AS), leading to recessionary pressures.
Question 15. Where does equilibrium lie in the long-run?
Answer: In the long-run, equilibrium occurs when Aggregate Demand is equal to the economy's long-run aggregate supply. At this point, the economy is operating at its full potential output, meaning all resources are fully utilized, and there are no inflationary or recessionary gaps. Prices and wages have fully adjusted, leading to a stable state. This represents the natural rate of output and employment.
In simple words: In the long run, the economy finds its balance when the total demand matches the highest amount it can make using all its resources.
🎯 Exam Tip: For long-run equilibrium, emphasize the full utilization of resources and the equality of Aggregate Demand with long-run Aggregate Supply.
Question 16. Name the main parts of fiscal policy.
Answer: The main parts of fiscal policy are:
1. Tax
2. Public Expenditure
3. Public Debt
These three components represent the tools that the government uses to influence the economy. By adjusting taxes, government spending, and borrowing, fiscal policy aims to achieve macroeconomic goals like economic growth and price stability. These tools help to manage overall demand in the economy.
In simple words: The main things that make up fiscal policy are taxes, how much the government spends, and the money the government borrows.
🎯 Exam Tip: Listing taxes, public expenditure, and public debt as the core elements of fiscal policy demonstrates a complete understanding of its components.
Question 18. Give examples of public expenditure.
Answer: Examples of public expenditure include various government investments and spending initiatives. These often involve infrastructure projects like building roads and dams, as well as social services such as constructing schools and hospitals. Additionally, public expenditure can cover salaries for government employees, defense spending, and subsidies. All these activities contribute to the overall economic activity and well-being.
In simple words: Public expenditure means money the government spends on things like building roads, dams, schools, and hospitals to help the country.
🎯 Exam Tip: Provide a mix of infrastructure and social service examples when asked about public expenditure to show broad knowledge.
Question 19. Which policy is adopted during Deficient Demand?
Answer: During a period of deficient demand, an Expansionary Monetary and Fiscal Policy is adopted. An expansionary monetary policy involves measures like lowering interest rates and increasing the money supply, while an expansionary fiscal policy involves increasing government spending and reducing taxes. Both policies aim to boost aggregate demand, stimulate economic activity, and move the economy out of a recession or depression. These measures encourage borrowing, spending, and investment.
In simple words: When demand is low, the government and central bank use policies to boost the economy. This means making money easier to get and spend, and the government spending more money itself.
🎯 Exam Tip: Remember that "expansionary" policies (both monetary and fiscal) are always used to counter deficient demand and stimulate the economy.
Question 20. Which policy is more successful during depression : Monetary or Fiscal ?
Answer: During a depression, Fiscal Policy is generally considered more successful than monetary policy. In a depression, businesses and consumers are often pessimistic, and even very low interest rates (from monetary policy) may not encourage investment or spending because there's little demand for goods and services and a lot of unsold inventory. However, direct government spending (fiscal policy) can create jobs and inject demand into the economy more effectively. Therefore, fiscal policy can more directly boost aggregate demand and help the economy recover. This is often referred to as a "liquidity trap" where monetary policy becomes ineffective.
In simple words: During a depression, fiscal policy (government spending and taxes) works better than monetary policy (interest rates). This is because even if banks offer cheap loans, businesses might not borrow if no one is buying their products. But government spending can directly create jobs and demand.
🎯 Exam Tip: Explain why fiscal policy is more effective during a depression by highlighting the limitations of monetary policy, such as the liquidity trap or lack of business confidence.
Question 21. Give examples of Direct tax.
Answer: Examples of direct taxes include Income Tax and Property Tax. Direct taxes are levied directly on the income or wealth of individuals and organizations, and their burden cannot be shifted to another person. They are typically progressive, meaning that those with higher incomes or more wealth pay a larger proportion of their earnings in taxes. Other examples might include corporate tax and wealth tax.
In simple words: Direct taxes are paid straight to the government by the person or company, such as income tax (on earnings) and property tax (on property owned).
🎯 Exam Tip: When providing examples, clearly state that direct taxes are paid by the person on whom they are levied and cannot be shifted.
Question 22. Give examples of Indirect Tax.
Answer: Examples of indirect taxes include Sales Tax, Custom Duty, and Goods and Service Tax (GST). Unlike direct taxes, the burden of indirect taxes can be shifted from the person or entity that initially pays them to the final consumer. These taxes are usually added to the price of goods and services. Consumers pay these taxes when they purchase items, making them a common part of everyday transactions.
In simple words: Indirect taxes are added to the price of goods and services, so customers pay them when they buy something, like sales tax or GST.
🎯 Exam Tip: Highlight that indirect taxes are imposed on goods and services, and their burden is typically shifted to the end consumer.
Question 23. What kind of monetary and fiscal policy is adopted during inflation?
Answer: During inflation, a Contractionary Monetary and Fiscal Policy is adopted. A contractionary monetary policy involves measures like increasing interest rates and reducing the money supply, while a contractionary fiscal policy involves decreasing government spending and increasing taxes. Both policies aim to reduce aggregate demand in the economy, thereby controlling rising prices and curbing inflation. These measures discourage borrowing, spending, and investment to cool down an overheated economy.
In simple words: To fight inflation, the central bank and government use policies to slow down the economy. They make it harder to borrow money and the government spends less, and collects more in taxes.
🎯 Exam Tip: Remember that "contractionary" policies (monetary and fiscal) are used to combat inflation by reducing aggregate demand.
Question 24. When is demonetisation done?
Answer: Demonetisation is typically carried out to remove certain currency notes from circulation, often to curb black money, stop the financing of illegal activities, reduce counterfeit currency, or encourage a shift towards a cashless economy. It involves making specific denominations of currency notes invalid as legal tender. This measure is usually adopted by the government or central bank as a significant economic policy tool to achieve these objectives. It causes immediate disruption but aims for long-term benefits.
In simple words: Demonetisation is done when the government decides to stop certain currency notes from being used as money. This is often done to fight illegal money or fake currency.
🎯 Exam Tip: Mention the primary reasons for demonetisation: combating black money, fake currency, and promoting digital transactions.
Question. How are general prices determined according to classical economists?
Answer: According to classical economists, general prices in an economy are primarily determined by the money supply. They believed in the Quantity Theory of Money, which states that if the money supply increases while the real output of the economy remains constant (assuming full employment), then the general price level will rise proportionally. Essentially, more money chasing the same amount of goods leads to higher prices. This theory emphasizes the role of money as a medium of exchange affecting price levels.
In simple words: Classical economists thought that overall prices are set by how much money is in circulation. If there's more money but the same amount of goods, prices will go up.
🎯 Exam Tip: Link the classical view of price determination directly to the Quantity Theory of Money, emphasizing the role of money supply.
Question 2. What is the assumption of Income and production principle according to Keynes ?
Answer: According to Keynes's Income and Production principle, the main assumption is that the price level is assumed to be constant in the short run. Keynes believed that during periods of underemployment, changes in aggregate demand primarily affect output and employment levels, not prices. This is because there are idle resources that can be utilized without putting upward pressure on wages or input costs, hence keeping prices stable. This contrasts with classical economists who assumed flexible prices.
In simple words: Keynes believed that for a while, prices do not change much. So, if people demand more, businesses just make more goods instead of raising prices, especially when there are unused resources.
🎯 Exam Tip: The key Keynesian assumption is the stickiness or constancy of the price level in the short run, which allows changes in demand to affect output and employment.
Question 3. What was the main cause of unemployment and additional production capacity as per Keynesian theory?
Answer: As per Keynesian theory, the primary cause of widespread unemployment and additional (idle) production capacity was the deficiency of effective demand. Keynes argued that if there isn't enough total spending (aggregate demand) in the economy, businesses won't have an incentive to produce more, leading to factories sitting idle and people being out of work. He believed that this lack of demand, rather than supply-side issues, was the root cause of economic downturns. His theory highlights the importance of government intervention to boost demand.
In simple words: Keynes thought that many people were jobless and factories were not being fully used because there was not enough total demand for goods and services in the economy.
🎯 Exam Tip: For Keynesian theory, always attribute unemployment and idle capacity to a "deficiency of effective demand."
Question 4. Explain the Aggregate Demand equation.
Answer: The Aggregate Demand (AD) equation is a fundamental concept in macroeconomics that represents the total spending in an economy. It is expressed as:
\( Y = C + I + G + X_n \)
Where:
\( C \) = Consumption Expenditure (spending by households on goods and services)
\( I \) = Investment Expenditure (spending by businesses on capital goods and inventory)
\( G \) = Government Expenditure (spending by the government on goods and services)
\( X_n \) = Net Export \( (X - M) \) (exports minus imports, representing spending by foreigners on domestic goods minus domestic spending on foreign goods)
This equation shows that the total output (Y) of an economy is equal to the sum of spending from all four sectors: households, businesses, government, and the foreign sector. Each component reflects a different source of demand in the economy.
In simple words: The Aggregate Demand equation adds up all the money spent in a country by people, businesses, the government, and from trading with other countries. It tells us the total demand for everything made.
🎯 Exam Tip: Clearly state the formula \( Y = C + I + G + X_n \) and define each of its four components precisely.
Question 5. On which assumption was the ideology of classical economists based ?
Answer: The ideology of classical economists was primarily based on the assumption of full employment. They believed that free markets naturally adjust to ensure that all available resources, including labor, are fully utilized in the long run. According to this view, any unemployment or underutilization of resources would be temporary, as wages and prices would quickly adjust to restore full employment equilibrium. This assumption forms the basis of their belief that government intervention is generally unnecessary.
In simple words: Classical economists believed that the economy naturally always has everyone working and all resources fully used, meaning there is always full employment.
🎯 Exam Tip: The core assumption for classical economists is "full employment," implying a self-correcting economy without idle resources in the long run.
Question 6. Define Aggregate Supply.
Answer: Aggregate Supply refers to the total quantity of goods and services that firms in an economy are willing and able to produce at different possible price levels over a specific period. This assumes that other factors, such as technology and resource availability, remain constant. Aggregate supply is influenced by the economy's productive capacity, which includes its labor force, capital stock, technology, and natural resources. It shows how much the economy can make under various conditions.
In simple words: Aggregate Supply is the total amount of all goods and services that businesses in a country are ready to make and sell at different prices.
🎯 Exam Tip: When defining Aggregate Supply, remember to include both "willingness" and "ability" to produce, covering various price levels.
Question. When does equilibrium occur in the long-run?
Answer: In the long-run, equilibrium occurs when Aggregate Demand is equal to aggregate supply in the long-term. This means the economy is operating at its natural rate of output, where all available resources are fully employed, and prices and wages have fully adjusted. At this point, there is no pressure for the economy to expand or contract, as it has reached its full potential without creating inflation or unemployment. This is a state of ideal balance where long-term sustainability is achieved.
In simple words: In the long run, the economy is balanced when the total demand for goods matches the maximum amount it can sustainably produce.
🎯 Exam Tip: Long-run equilibrium implies that AD equals long-run AS, signifying full employment and potential output without inflationary or recessionary gaps.
Question 9. What will be the effect of raising taxes on Investment ?
Answer: Raising taxes can have a negative impact on both investment and overall production. When taxes are higher, businesses and individuals have less disposable income and profit, which reduces their incentive and capacity to invest in new projects or expand existing ones. This lack of investment can slow down economic growth and lead to lower production levels.
In simple words: If taxes go up, people and companies might invest less money and make fewer things because they have less money left.
🎯 Exam Tip: Always consider both the direct and indirect impacts of fiscal policies like taxation. Higher taxes directly reduce available funds and indirectly dampen investment confidence.
Question 10. When should government implement compulsory savings scheme ?
Answer: The government should implement a compulsory savings scheme primarily to control inflation. During periods of high inflation, there is too much money chasing too few goods, leading to rising prices. By making savings compulsory, the government reduces the amount of money available for spending in the economy, which in turn helps to cool down demand and stabilize prices.
In simple words: The government should make people save money to help stop prices from going up too fast and control inflation.
🎯 Exam Tip: Compulsory savings schemes are a direct way to reduce aggregate demand in an inflationary environment, but they can be unpopular as they limit immediate consumption.
RBSE Class 12 Economics Chapter 22 Short Answer Type Questions (SA-II)
Question 1. Explain Keynesean law of income and output ?
Answer: According to Keynesian law, the general price level remains constant. Income in an economy is determined at the point where the total demand for goods and services (Aggregate Quantity Demand) equals the total supply (Aggregate Supply). Keynes argued that the main reason for an economic depression was a lack of effective demand in the economy.
In simple words: Keynes said that a country's income and how much it produces are decided when total demand meets total supply, and a lack of demand is the main cause of economic problems.
🎯 Exam Tip: Remember that Keynesian economics emphasizes the role of aggregate demand and government intervention, especially during recessions or depressions, contrasting with classical views.
Question 2. Explain Aggregate Demand.
Answer: Aggregate Demand is the total amount of goods and services that all sectors of an economy are willing to buy at a given price level during a specific period. It includes what households spend on consumption (C), what businesses invest (I), what the government purchases (G), and the net exports (exports minus imports, \(X_n\)). When all other factors remain constant, the total quantity of goods and services demanded by consumers, investors, the government, and foreign buyers makes up Aggregate Demand. The formula for Aggregate Demand is \( Y = C + I + G + X_n \).
In simple words: Aggregate Demand is the total amount of everything (like goods, services, and investments) that everyone in a country wants to buy at a certain time.
🎯 Exam Tip: Clearly listing and defining the four components (Consumption, Investment, Government Spending, Net Exports) is crucial for a complete explanation of Aggregate Demand.
Question 3. Describe the effects of price rise.
Answer: The provided text indicates that the following points describe the effects of a price rise, but the specific details are missing from the source content.
In simple words: The effects of prices going up would normally be explained here, but the details are not available.
🎯 Exam Tip: When asked to describe effects, always list key consequences like reduced purchasing power, changes in consumption patterns, and impact on production costs.
Question 4. Show Inverse Aggregate Demand on various price levels through a diagram.
Answer: The diagram below illustrates the inverse relationship between the general price level and aggregate production demand. As the price level changes, the corresponding aggregate production demand also changes, showing how demand generally decreases when prices rise. This downward-sloping Aggregate Demand (AD) curve visually represents this inverse correlation, highlighting that at higher price levels, less output is demanded.
In simple words: This diagram shows that when prices go up, people and businesses want to buy less, and when prices go down, they want to buy more. It's like a slope going downwards.
🎯 Exam Tip: When drawing economic graphs, ensure all axes are clearly labeled, curves are correctly sloped, and equilibrium points or relevant levels are accurately marked.
Question 5. What do you meant by depression?
Answer: Depression refers to a severe and prolonged downturn in economic activity. This situation is characterized by a significant reduction across various economic indicators, including the production of goods and services, widespread unemployment, decreased income levels, falling consumer demand, and a general decline in prices.
In simple words: Depression means when the economy gets very bad, with much less production, many people losing jobs, and lower prices for everything.
🎯 Exam Tip: Differentiate depression from recession by emphasizing its longer duration and more severe impact on economic output and employment.
Question 6. What is prosperity?
Answer: Prosperity describes an economic period marked by high levels of output, employment, and income. During this phase, there is a strong increase in the demand for goods and services, often accompanied by an inflationary rise in prices. This indicates a robust and growing economy.
In simple words: Prosperity is when the economy is doing very well, with lots of production, many jobs, high income, and a lot of demand, which can also make prices go up.
🎯 Exam Tip: When defining economic phases like prosperity, link them to key indicators such as GDP, employment rates, and inflation to provide a comprehensive answer.
Question 7. What steps are taken in monetary policy during depression?
Answer: During a depression, monetary policy focuses on stimulating the economy. The steps typically taken include:
1. The central bank increases the supply of money, which helps to reduce interest rates.
2. Other interest rates are also lowered, alongside efforts to increase Aggregate Demand. These actions make it cheaper for businesses to borrow and invest, thereby encouraging economic activity and creating jobs.
In simple words: To fix a depression, the central bank makes more money available and lowers borrowing costs, hoping people will spend and invest more.
🎯 Exam Tip: Focus on how lowering interest rates and increasing money supply are the primary tools of expansionary monetary policy during a depression to encourage borrowing and spending.
Question 9. Monetary policy is not much successful during depression. Why ?
Answer: Monetary policy often struggles to be very effective during a depression because, even when interest rates are lowered significantly, businesses might already have a large stock of unsold goods. This means they have little motivation to invest more or expand production, regardless of how cheap borrowing becomes. Additionally, consumers facing unemployment and low income are not inclined to borrow money, even for durable goods, due to economic uncertainty. Therefore, monetary policy alone often fails to stimulate demand and investment effectively in such deep downturns.
In simple words: Monetary policy does not work well in a depression because businesses have too many unsold goods and people do not have money to borrow, even if borrowing is cheap, so demand stays low.
🎯 Exam Tip: In a depression, a "liquidity trap" can occur where further reductions in interest rates do not stimulate borrowing or investment, highlighting the limits of monetary policy.
RBSE Class 12 Economics Chapter 22 Essay Type Question
Question 1. Explain the derivation of Aggregate Demand with the help of a diagram.
Answer: The derivation of Aggregate Demand can be understood by relating aggregate expenditure to price levels, as shown in the diagrams. Figure (a) illustrates Aggregate Expenditure, which includes investment spending, at different levels of Gross National Product (GNP) as conceptualized by Keynes. Figure (b) then shows the derived Aggregate Demand at different price levels. At an increased price level, equilibrium occurs at point E in Figure (a), where Aggregate Demand (AD) equals Aggregate Supply (AS) at income level Y₁. However, as prices rise, Aggregate Demand reduces and reaches a lower level, like OC₁. This clearly demonstrates an inverse relationship between the general price level and Aggregate Production Demand, which is visibly represented by the downward-sloping AD curve in Figure (b), indicating that higher prices lead to lower overall demand.
In simple words: We can see Aggregate Demand with two pictures. One picture shows how much people spend at different income levels. The second picture shows that when prices go up, people want to buy less, and when prices go down, they want to buy more.
🎯 Exam Tip: When explaining diagrams, always refer to the specific axes, curves, and points, and clearly state what each represents to demonstrate a full understanding.
