ex ante

adj. being applied from before an action. The concept of an ‘ex ante’ approach to economics, together with that of ex post (‘from after’), is widely employed in economic analysis to examine the change in some economic phenomenon as it moves from a state of DISEQUILIBRIUM to one of EQUILIBRIUM. For example, in the Keynesian model of national income determination, planned investment may be greater than planned saving so that the economic system is in a state of disequilibrium. The excess of investment, however, serves to inject additional income into the economy and, via the MULTIPLIER effect, increases both income and saving, bringing about an eventual ‘ex post’ equilibrium where realized investment equals realized savings. See EQUILIBRIUM LEVEL OF NATIONAL INCOME.
