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.

When combined, both shifts result in an increase in equilibrium quantity and an indeterminant change in equilibrium price.
