AGGREGATE EXPENDITURE 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.

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.
