Quiz on Income & Spending

What does Aggregate Demand (AD) represent?

• Total government spending

• Total amount consumers wish to spend on goods and services

• Total income earned by individuals

• Total exports minus imports

Answer explanation

Aggregate Demand (AD) represents the total amount consumers wish to spend on goods and services in an economy. It reflects overall demand and is a key component in understanding economic activity.

Which of the following is NOT a component of Aggregate Demand?

• Net Savings (NS)

• Government Spending (G)

• Investment Spending (I)

• Consumer Expenditure (C)

Answer explanation

Net Savings (NS) is not a component of Aggregate Demand. The components include Government Spending (G), Investment Spending (I), and Consumer Expenditure (C), which together represent total demand in the economy.

What does the Marginal Propensity to Consume (MPC) indicate?

• The level of government spending

• The total income of the economy

• The fraction of additional income spent on consumption

• The total savings of consumers

Answer explanation

The Marginal Propensity to Consume (MPC) measures the fraction of additional income that households spend on consumption. Thus, the correct choice is 'The fraction of additional income spent on consumption'.

What is the formula for calculating Disposable Income (DI)?

• DI = National Income - Taxes

• DI = National Income + Transfers

• DI = National Income - (Taxes + Transfers)

• DI = National Income + Taxes

Answer explanation

Disposable Income (DI) is calculated by subtracting both taxes and transfers from national income. Thus, the correct formula is DI = National Income - (Taxes + Transfers). This reflects the income available for spending or saving.

Which method is NOT used to measure GDP?

• Imports and exports

• Savings and taxes

• Government transfer payments

• Expenditures on domestic goods from outside the household sector

Answer explanation

In the Circular Flow of Income, 'Injections' refer to expenditures on domestic goods from outside the household sector, such as investments, government spending, and exports, which stimulate economic activity.

What is the relationship between Marginal Propensity to Consume (MPC) and Marginal Propensity to Save (MPS)?

• MPC + MPS = 2

• MPC + MPS = 1

• MPC * MPS = 1

• MPC - MPS = 1

Answer explanation

The Marginal Propensity to Consume (MPC) and Marginal Propensity to Save (MPS) represent the portions of additional income that are consumed and saved, respectively. Since all income must be either consumed or saved, MPC + MPS = 1.

Which of the following factors does NOT cause a shift in the consumption function?

• Government spending

• Inflation rate

• Price level

Government spending does not directly affect the consumption function, which is influenced by factors like consumer wealth, inflation rate, and price level. Thus, it is the correct choice as it does NOT cause a shift.

What is the primary purpose of the Output Method/Value Added Approach?

• To measure total income in the economy

• To avoid double counting of intermediate goods

• To calculate government spending

• To determine consumer spending

Answer explanation

The primary purpose of the Output Method/Value Added Approach is to avoid double counting of intermediate goods, ensuring that only the final value of goods and services produced in the economy is measured.

Which of the following is included in GDP calculations?

• Second-hand products

• Do it yourself activities

• Goods added to inventories
