LONG-RUN AGGREGATE SUPPLY CURVE: A graphical representation of the long-run relation between real production and the price level, holding all ceteris paribus aggregate supply determinants constant. The long-run aggregate supply, or LRAS, curve is one of two curves that graphical capture the supply-side of the aggregate market; the other is the short-run aggregate supply curve (SRAS). The demand-side of the aggregate market is occupied by the aggregate demand curve. The vertical LRAS curve captures the independent relation between real production and the price level that exists in the long 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.
