Question 1

What are the two main components of government purchases in the expenditure approach?

Accepted Answer

Government purchases consist of government consumption expenditures and gross investment. Consumption expenditures cover services like national defense, public education, and law enforcement. Gross investment includes spending on fixed assets such as highways, bridges, and military equipment. Together, these components reflect the government's role in providing essential services and expanding the economy's productive capacity.

Question 2

How are non-market government services valued in GDP calculations?

Accepted Answer

Non-market government services like national defense and public education are valued based on their cost of production rather than market prices. This includes wages, salaries, and other expenses incurred to provide these services. For example, salaries paid to public school teachers and police officers are counted as government consumption expenditures in GDP, even though these services are provided free to the public.

Question 3

Why are transfer payments excluded from government purchases in GDP?

Accepted Answer

Transfer payments like unemployment insurance and Social Security benefits are excluded from GDP because they represent monetary transfers without a corresponding exchange of goods or services. Since transfer payments do not reflect current production, they do not contribute to the measure of economic output. Only government spending on actual services and investments counts toward GDP.

Question 4

What types of fixed assets are included in government gross investment?

Accepted Answer

Government gross investment includes spending on fixed assets such as highway construction, bridge building, public buildings, schools, and equipment like new military hardware. These investments expand the economy's productive capacity and provide infrastructure that supports economic activity. Such spending is distinct from government consumption expenditures and represents capital formation by the public sector.

Question 5

How do government consumption expenditures differ from government gross investment?

Accepted Answer

Government consumption expenditures cover spending on services provided to the public, such as defense, education, and law enforcement, valued at their production cost. Government gross investment, by contrast, focuses on spending for fixed assets like infrastructure and equipment that expand productive capacity. While consumption addresses immediate service delivery, investment builds long-term economic assets.

Question 6

What role do government salaries play in measuring government consumption expenditures?

Accepted Answer

Government salaries, such as those paid to public school teachers and police officers, are counted as government consumption expenditures in GDP. Since government services are not sold in markets, their value is measured by production costs, including employee wages. These salaries represent the government's spending on human resources needed to deliver essential public services.

Question 7

How does government spending on infrastructure contribute to the expenditure approach to GDP?

Accepted Answer

Government spending on infrastructure, such as highway and bridge construction, is classified as gross investment within the expenditure approach. This spending increases the economy's productive capacity and is counted as part of the G component in the GDP formula. Infrastructure investment reflects the government's role in supporting long-term economic growth and development.
