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.

SHORT RUN, MACROECONOMICS In terms of macroeconomic analysis, especially the aggregate market (AS-AD) analysis, a period of time in which some prices, notably 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. Short-run wage and price rigidity prevents some markets, especially resource 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.
