Answer to Question 1

A

Answer to Question 2

The increase in aggregate demand means that the AD curve shifts rightward. Initially short-run aggregate supply does not change, so the SAS curve remains stationary. As a result, the price level rises and real GDP increases. The economy is an above-full-employment equilibrium. Eventually, however, the tight labor market leads to a rise in the money wage rate. When the money wage rate rises, short-run aggregate supply decreases and the SAS curve shifts leftward. The price level rises and real GDP decreases. In the long run, the short-run aggregate supply decreases so that real GDP returns to potential level of GDP and the only effect is that the price level is permanently higher.
