KEYNESIAN CROSS: The standard diagram used in Keynesian economics to identify the equilibrium level of aggregate output (that is, gross domestic product), with aggregate expenditures measured on the vertical axis, and aggregate output measured on the horizontal axis. This diagram contains two key lines, the aggregate expenditure line and the 45-degree line. Intersection between these lines indicates equilibrium aggregate output. This intersection, or cross, is what gives rise to the name.

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants. First, rigid or inflexible prices prevent some markets from achieving equilibrium in the short run. Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.
