RIGID PRICES: The proposition that some prices adjust slowly in response to market shortages or surpluses. This condition is most important for macroeconomic activity in the short run and short-run aggregate market analysis. In particular, rigid (also termed inflexible or sticky) prices are a key reason underlying the positive slope of the short-run aggregate supply curve. Prices tend to be the most rigid in resource markets, especially labor markets, and the least rigid in financial markets, with product markets falling somewhere in between.

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants.

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.
