Suppose GDP is $8 trillion, taxes are $1.5 trillion, private saving is $0.5 trillion, and public saving is $0.2 trillion. Assuming this economy is closed, calculate consumption, government purchases, national saving, and investment.

Consumption = $6 trillion

government purchases = $1.3 trillion

national saving = $0.7 trillion and

investment = $0.7 trillion

Explanation:GDP is the market value of all final goods and services within an economy during a given period.

GDP = Consumption + Investment/National Savings + Government Expenditure/purchases (in a closed economy)

National Savings/ Investment = Private saving + public saving = $0.5 trillion +$ 0.2 trillion = $0.7 trillion.

Government purchases = Taxes - Public saving = $1.5 trillion - $0.2 trillion = $1.3 trillion

Since, GDP = Consumption + Investment/National Savings + Government Expenditure/purchases (in a closed economy)

Therefore, Consumption = GDP - Investment - Government Expenditure

Consumption = $8trillion - $0.7trillion - $1.3trillion = $6 trillion
