AGGREGATE EXPENDITURES 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.

RISK

The quantitative probability of different future outcomes occurring. The assignment of probabilities can be subjective (based on a "feeling") or objective (based on historical data). Risk is related to the concept of uncertainty, which is simply not knowing what the future holds. People have three alternative preferences when confronting risk -- risk aversion, risk neutrality, and risk loving. Risk aversion is key to the provision of insurance.
