SHORT-RUN AGGREGATE SUPPLY: The total (or aggregate) real production of final goods and services available in the domestic economy at a range of price levels, during a period of time in which some prices, especially wages, are rigid, inflexible, or otherwise in the process of adjusting. Short-run aggregate supply (SRAS) is one of two aggregate supply alternatives, distinguished by the degree of price flexibility; the other is long-run aggregate supply. Short-run aggregate supply is combined with aggregate demand in the short-run aggregate market analysis used to analyze business-cycle instability, unemployment, inflation, government stabilization policies, and related macroeconomic topics.

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.
