Class: CBSE Class 12
Subject: Economics
Section: Determination of Income and Employment — Introductory Macroeconomics
Topic: Equilibrium Level of Income
Exam Focus: CBSE Board Examinations (NCERT Based)
1. Equilibrium level of income is determined where:
Answer: A. Saving = Investment
At equilibrium, planned savings equal planned investment. This ensures that aggregate demand equals aggregate supply, stabilizing income.
At equilibrium, planned savings equal planned investment. This ensures that aggregate demand equals aggregate supply, stabilizing income.
2. In the Keynesian model, equilibrium income is where:
Answer: C. AD = AS
Equilibrium occurs when Aggregate Demand equals Aggregate Supply. Firms sell exactly what they produce.
Equilibrium occurs when Aggregate Demand equals Aggregate Supply. Firms sell exactly what they produce.
3. The 45° line in the income determination diagram shows:
Answer: C. Income = Output
The 45° line represents points where planned expenditure equals income.
The 45° line represents points where planned expenditure equals income.
4. When planned investment exceeds planned saving:
Answer: B. Income rises
Excess investment increases demand, leading to higher production and income.
Excess investment increases demand, leading to higher production and income.
5. Equilibrium level of income is also called:
Answer: D. All of these
It represents the level where economy is stable with no unintended inventory changes.
It represents the level where economy is stable with no unintended inventory changes.
6. Aggregate Demand consists of:
Answer: A. C + I
In a two‑sector economy, AD includes Consumption and Investment.
In a two‑sector economy, AD includes Consumption and Investment.
7. If AD is greater than AS, inventories will:
Answer: B. Fall
Higher demand than supply reduces stock, prompting firms to increase output.
Higher demand than supply reduces stock, prompting firms to increase output.
8. The point where AD curve cuts 45° line is:
Answer: C. Equilibrium
Intersection shows planned spending equals income.
Intersection shows planned spending equals income.
9. Saving curve intersects investment curve at:
Answer: A. Equilibrium income
Equality of S and I determines equilibrium.
Equality of S and I determines equilibrium.
10. Autonomous investment is:
Answer: B. Income independent
It remains constant regardless of income level.
It remains constant regardless of income level.
11. When saving exceeds investment:
Answer: B. Income falls
Lower investment reduces demand causing fall in output and income.
Lower investment reduces demand causing fall in output and income.
12. Planned expenditure equals:
Answer: A. AD
Aggregate demand represents planned spending.
Aggregate demand represents planned spending.
13. Equilibrium income is stable because:
Answer: D. All of these
All conditions ensure macroeconomic stability.
All conditions ensure macroeconomic stability.
14. Leakage in income flow refers to:
Answer: B. Saving
Savings withdraw income from the circular flow.
Savings withdraw income from the circular flow.
15. Injection into income flow is:
Answer: C. Investment
Investment adds spending into the economy.
Investment adds spending into the economy.
16. Equilibrium output is determined in:
Answer: A. Goods market
It is where AD equals AS.
It is where AD equals AS.
17. Multiplier affects equilibrium by:
Answer: B. Changing investment impact
Multiplier magnifies the effect of investment on income.
Multiplier magnifies the effect of investment on income.
18. If MPC rises, equilibrium income will:
Answer: B. Rise
Higher MPC increases multiplier and income.
Higher MPC increases multiplier and income.
19. Deficient demand means:
Answer: B. AD < AS
Lower demand leads to unemployment and lower equilibrium.
Lower demand leads to unemployment and lower equilibrium.
20. Excess demand leads to:
Answer: B. Inflationary gap
Excess AD over AS creates upward pressure on prices.
Excess AD over AS creates upward pressure on prices.
