AGGREGATE EXPENDITURE EQUATION: An equation indicating that aggregate expenditures (AE) are the sum of consumption expenditures (C), investment expenditures (I), government purchases (G), and net exports (X-M), stated as: AE = C + I + G + (X-M). This equation surfaces in the Keynesian economic income-expenditure model in the form of the aggregate expenditures line. However, it's also central throughout the study of macroeconomics, including aggregate demand and the measurement of gross domestic product.

- Long-run Production: Each production operation also engages in long-run planning even while it is engaged in short-run production.

IMPACT LAG The time lag that occurs between the implementation of a government policy designed to correct an economic problem and the complete impact of the policy. The impact lag is based on the multiplier process and can last up to a year or two or even longer. This "outside lag" is one of four policy lags associated with monetary and fiscal policy. The other three "inside lags" are recognition lag, decision lag, and implementation lag. All four policy lags can reduce the effectiveness of business-cycle stabilization policies and can even destabilize the economy.
