To determine which groups contribute to total GDP, we can reference the components of GDP. GDP can be calculated using the expenditure approach, which includes the following components:
- Consumer Spending (Household Spending): This includes all private consumption expenditures.
- Investment: This includes capital goods, residential investment, and business investments.
- Government Spending: This refers to government expenditures on goods and services.
- Net Exports: This is the value of a country's exports minus its imports (Net Exports = Exports - Imports).
Now, let's analyze the provided groups:
-
Human records, raw materials, capital goods: This does not directly align with the GDP components. While capital goods contribute to investment, human records and raw materials are not classified as components of GDP.
-
Government spending, capital goods, net imports: This includes government spending (contributes to GDP), and capital goods (part of investment). Net imports are not a component; however, net exports (exports minus imports) do contribute negatively or positively to GDP.
-
Net imports, net exports, household spending: Net imports (which are imports exceeding exports) do not contribute positively to GDP. Net exports are the correct term, but this listing is incorrect because of the inclusion of net imports.
-
Net exports, household spending, government spending: This is the correct answer. All three components contribute positively to GDP.
Therefore, the correct group that contributes to total GDP is:
Net exports, household spending, government spending.
