AE LINE: Another term for aggregate expenditure line, which is 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.

UNDERGROUND ECONOMY Illegal and unreported market transactions and productive activity that escape the watchful eyes of official record keepers. By most estimates, a substantial amount of productive activity takes place in the underground economy of the United States. Of course, these are only estimates because such activity, by definition, goes unreported. If activity in the underground economy is added to official activity in the "overground" economy, then gross domestic product could be boosted by as much as 25 percent to 50 percent, or more. Inclusion of employment in the underground economy is also likely reduce the official unemployment rate by a few percentage points.
