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.

GOOD TYPES The economy produces four distinct types of goods based on two key characteristics -- consumption rivalry and nonpayer excludability. Consumption rivalry arises if consumption of a good by one person prevents another from also consuming. Nonpayer excludability means potential consumers who do not pay for a good can be excluded from consuming. Private goods are rival in consumption and easily subject to the exclusion of nonpayers. Public goods are nonrival in consumption and the exclusion of nonpayers is virtually impossible. Near-public goods are nonrival in consumption and easily subject to exclusion. Common-property goods are rival in consumption and not easily subject to exclusion. Private goods can be efficiently exchanged through markets. Public, near-public and common-property goods cannot, but require some degree of government involvement for efficiency.
