AGGREGATE MARKET ANALYSIS: An investigation of macroeconomic phenomena, including unemployment, inflation, business cycles, and stabilization policies, using the aggregate market interaction between aggregate demand, short-run aggregate supply, and long-run aggregate supply. Aggregate market analysis, also termed AS-AD analysis, has been the primary method of investigating macroeconomic activity since the 1980s, replacing Keynesian economic analysis that was predominant for several decades. Like most economic analysis, aggregate market analysis employs comparative statics, the technique of comparing the equilibrium after a shock with the equilibrium before a shock. While the aggregate market model is usually presented as a simply graph at the introductory level, more sophisticated and more advanced analyses often involve a system of equations.

LONG RUN, MACROECONOMICS In terms of the macroeconomic analysis of the aggregate market, a period of time in which all prices, especially wages, are flexible, and are able to achieve equilibrium levels. This is one of two macroeconomic time designations; the other is the short run. Long-run wage and price flexibility means that ALL markets, including resource markets and most notably labor markets, are in equilibrium, with neither surpluses nor shortages. Wage and price flexibility and the resulting resource market equilibria are the reason for the vertical long-run aggregate supply curve.
