Aggregate Demand and Aggregate Supply
Aggregate Demand and Aggregate Supply: The Long Run and the Short Run
ANSWER TO TRY IT! PROBLEM
All components of aggregate demand (consumption, investment, government purchases, and net exports) declined between 1929 and 1933. Thus the aggregate demand curve shifted markedly to the left, moving from AD1929 to AD1933.
The reduction in nominal wages corresponds to an increase in short-run aggregate supply from SRAS1929 to SRAS1933. Since real GDP in 1933 was less than real GDP in 1929, we know that the movement
in the aggregate demand curve was greater than that of the short-run aggregate supply curve.
