Identify the four components of aggregate demand and briefly describe how a rise in each would affect overall demand.

• A. Consumption, Investment, Government Spending, Net Exports; increases in any raise AD.
• B. Wages, Prices, Employment, Exchange Rates; increases in any raise AD.
• C. Investment, Financial Assets, Taxes, Currency; increases in any raise AD.
• D. Taxes, Transfers, Imports, Government Debt; increases in any raise AD.

Answer: (A)

The four components of aggregate demand are consumption, investment, government spending, and net exports. A rise in any of these raises overall demand in the economy.

Consumption is the spending by households on goods and services. When households spend more—perhaps because their incomes rise or they feel wealthier—their larger purchases push total demand higher.

Investment refers to business spending on capital like factories, equipment, and software. If firms expect higher future profits, or if borrowing costs fall, they spend more now, boosting demand for goods and services and, indirectly, employment.

Government spending is purchases by the government on goods and services. When the government spends more, it directly adds to demand in the economy, often leading to more production and jobs.

Net exports are exports minus imports. If a country sells more abroad or buys less from abroad, net exports rise, increasing domestic demand for goods and services. Conversely, a fall in net exports would reduce aggregate demand.

Why the other options don’t fit as the standard breakdown: those groups mix factors that affect prices or supply or are only indirectly related to aggregate demand, rather than being the four direct components of AD in the basic framework.
