Aggregate Demand and Aggregate Supply Review
Review sections 7.2 and 7.3 of Chapter 7 in order to examine the relationship between the labor market dynamics and the achievement of equlibrium in the short run and the long run. Note the role of wage and price stickiness.
7.2 Aggregate Demand and Aggregate Supply: The Long Run and the Short Run
The tools we have covered in this section can be used to understand the Great Depression of the 1930s. We know that investment and consumption began falling in late 1929. The reductions were reinforced by plunges in net exports and government purchases over the next four years. In addition, nominal wages plunged 26% between 1929 and 1933. We also know that real GDP in 1933 was 30% below real GDP in 1929. Use the tools of aggregate demand and short-run aggregate supply to graph and explain what happened to the economy between 1929 and 1933.
