Economics: Circular Flow of Income Worksheet

Question 1

In a simple circular flow model with only households and firms, describe the two main flows between them.

Accepted Answer

Households provide factors of production such as labor, land, capital, and entrepreneurship to firms. Firms pay households income in the form of wages, rent, interest, and profit, while households use income to buy goods and services from firms.

Question 2

Identify the role of households in the circular flow of income.

Accepted Answer

Households own the factors of production and sell them to firms in factor markets. Households also spend income in product markets to buy goods and services.

Question 3

Identify the role of firms in the circular flow of income.

Accepted Answer

Firms buy or hire factors of production from households and use them to produce goods and services. Firms sell those goods and services in product markets and receive revenue from household spending.

Question 4

Explain the difference between a product market and a factor market.

Accepted Answer

A product market is where goods and services are bought and sold. A factor market is where resources used to produce goods and services, such as labor and capital, are bought and sold.

Question 5

A student works at a grocery store and earns $120. The student then spends $40 at a restaurant. Explain how both transactions fit into the circular flow model.

Accepted Answer

When the student earns $120, the household is selling labor in the factor market and receiving income from a firm. When the student spends $40 at a restaurant, the household is buying a service in the product market and the firm is receiving revenue.

Question 6

In a circular flow diagram, household spending on goods and services is usually called consumption. Explain why consumption is important for firms.

Accepted Answer

Consumption is important because it becomes revenue for firms. Firms use revenue to pay for resources, produce more goods and services, and earn profit.

Question 7

Add the government to the circular flow model. Describe two ways the government interacts with households and firms.

Accepted Answer

The government collects taxes from households and firms. The government also provides goods and services, such as roads, schools, and public safety, and may make payments such as wages, subsidies, or transfer payments.

Question 8

Explain how taxes affect the circular flow of income.

Accepted Answer

Taxes are a leakage from household and firm income because they reduce the money available for private spending or investment. However, government spending can inject money back into the circular flow.

Question 9

Explain how saving affects the circular flow of income.

Accepted Answer

Saving is a leakage because money is not immediately spent on goods and services. If savings are used by banks and financial institutions to fund investment, the money can return to the circular flow as an injection.

Question 10

A household earns $3,000 in income during a month. It pays $600 in taxes, saves $400, and spends the rest on goods and services. How much is consumption spending?

Accepted Answer

Consumption spending is $2,000. This is found by subtracting taxes and savings from income: $3,000 minus $600 minus $400 equals $2,000.

Question 11

In an open economy, explain how imports and exports affect the circular flow of income.

Accepted Answer

Imports are a leakage because money leaves the domestic economy to buy goods and services from other countries. Exports are an injection because foreign buyers spend money on domestically produced goods and services.

Question 12

Classify each item as a leakage or an injection in the circular flow: household saving, business investment, taxes, government spending, imports, exports.

Accepted Answer

Household saving is a leakage. Business investment is an injection. Taxes are a leakage. Government spending is an injection. Imports are a leakage. Exports are an injection.
