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.

INFLATION PROBLEMS Two notable problems are associated with inflation--uncertainty and haphazard redistribution. Inflation, especially inflation that varies from month to month and year to year, makes long-term planning quite difficult. Prices, wages, taxes, interest rates, and other nominal values that enter into consumer, business, and government planning decisions can be significantly affected by inflation. Moreover, inflation tends to redistribute income and wealth in a haphazard manner--some people win and some people lose. This redistribution might not be that desired by society, failing to promote any of the basic economic goals of efficiency, equity, stability, growth, or full-employment.
