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.

ZERO-SUM GAME: A situation in which a fixed amount is divided up among the winners and losers. In a zero-sum game the wins equal the losses. Many stock market, or financial market, exchanges are zero-sum. One person buys low and sells high, while another buys high and sells low. The wealth in such transactions are merely transferred from one person to another. "Productive" market transactions, in contrast, are not zero-sum. The act of producing goods and services from resources that are consumed to satisfy wants and needs results in a net gain to society.
