Chapter 29 - Aggregate demand and aggregate supply. This chapter define aggregate demand (AD) and explain the factors that cause it to change; define aggregate supply (AS) and explain the factors that cause it to change; discuss how AD and AS determine an economy's equilibrium price level and level of real GDP; describe how the AD-AS model explains periods of demand-pull inflation, cost-push inflation, and recession; identify how the aggregate demand curve relates to the aggregate expenditures model. | Aggregate Demand and Aggregate Supply Chapter 29 McGraw-Hill/Irwin Copyright © 2009 by The McGraw-Hill Companies, Inc.
