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.

7.3 Recessionary and Inflationary Gaps and Long-Run

Restoring Long-Run Macroeconomic Equilibrium

We have already seen that the aggregate demand curve shifts in response to a change in consumption, investment, government purchases, or net exports. The short-run aggregate supply curve shifts in response to changes in the prices of factors of production, the quantities of factors of production available, or technology. Now we will see how the economy responds to a shift in aggregate demand or short-run aggregate supply using two examples presented earlier: a change in government purchases and a change in health-care costs. By returning to these examples, we will be able to distinguish the long-run response from the short-run response.
