AGGREGATE EXPENDITURE LINE: A line representing the relation between aggregate expenditures and gross domestic product used in the Keynesian cross. The aggregate expenditure line is obtained by adding investment expenditures, government purchases, and net exports to the consumption line. As such, the slope of the aggregate expenditure line is largely based on the slope of the consumption line (which is the marginal propensity to consume), with adjustments coming from the marginal propensity to invest, the marginal propensity for government purchases, and the marginal propensity to import. The intersection of the aggregate expenditures line and the 45-degree line identifies the equilibrium level of output in the Keynesian cross.

IMPLEMENTATION LAG The time lag that occurs after a government policy designed to correct an economic problem has been selected and the actual execution of the policy. The implementation lag is based the time it takes for government agencies, which can be slow and methodical, to carry out the designated policy. This "inside lag" is one of four policy lags associated with monetary and fiscal policy. The other two "inside lags" are recognition lag and decision lag, and one "outside lag" is implementation lag. All four policy lags can reduce the effectiveness of business-cycle stabilization policies and can even destabilize the economy.
