SHORT RUN, MACROECONOMICS: In terms of the macroeconomic analysis of the aggregate market, a period of time in which some prices, especially wages, are rigid, inflexible, or otherwise in the process of adjusting. This is one of two macroeconomic time designations; the other is the long run (you might want to see short-run production, too). Short-run wage and price rigidity prevents some markets, especially resources markets and most notably labor markets, from achieving equilibrium. Wage and price rigidity and the resulting resource market imbalances are the source of the positively-sloped short-run aggregate supply curve.

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.

AUTONOMOUS INVESTMENT Business investment expenditures that do not depend on income or production (especially national income or even gross domestic product). That is, changes in income do not generate changes in investment. Autonomous investment is best thought of as investment that the business sector undertakes regardless of the state of the economy. It is measured by the intercept term of the investment line. The alternative to autonomous investment is induced investment, which does depend on income.
