In economics, aggregate demand for final goods is determined by several components that comprise the total demand within an economy. These components are usually listed in the form of the aggregate demand equation:
\(AD = C + I + G + (X - M)\)
The options given include:
Government spending: This is part of aggregate demand, as it directly impacts the economy by purchasing goods and services.
Imports: While relevant, imports are subtracted from exports to calculate net exports and do not contribute positively to aggregate demand.
Savings: This is part of how income is allocated and does not directly increase aggregate demand. Instead, higher savings can reduce consumption.
Taxes: These are government revenues that also do not directly contribute to aggregate demand. They can influence it indirectly by altering disposable income.
Among the given options, the correct component of aggregate demand is Government spending.
