TAILIEUCHUNG - Lecture Business economics - Lecture 24: Aggregate Demand and Aggregate Supply

This chapter introduces the model’s two key pieces—the aggregate-demand curve and the aggregatesupply curve. After getting a sense of the overall structure of the model in this chapter, we examine the pieces of the model in more detail in the next two chapters. | Review of the previous Lecture All societies experience short-run economic fluctuations around long-run trends. These fluctuations are irregular and largely unpredictable. When recessions occur, real GDP and other measures of income, spending, and production fall, and unemployment rises. Review of the previous Lecture Economists analyze short-run economic fluctuations using the aggregate demand and aggregate supply model. According to the model of aggregate demand and aggregate supply, the output of goods and services and the overall level of prices adjust to balance aggregate demand and aggregate supply. Review of the previous Lecture The aggregate-demand curve slopes downward for three reasons: a wealth effect, an interest rate effect, and an exchange rate effect. Any event or policy that changes consumption, investment, government purchases, or net exports at a given price level will shift the aggregate-demand curve.
