Illustrate graphically what would happen in the short run and in the long run to the price level and Real GDP if individuals hold rational expectations, prices and wages are flexible, and individuals overestimate the rise in aggregate demand (bias upward).
Assume that the housing market is in equilibrium in year 1. In year 2, the mortgage rate that banks charge consumers decreases, but producers are not affected. Also in year 2, the cost of lumber used to build homes decreases. Which of the following is most likely to be the equilibrium change?
a
The equilibrium will be at point C before the change in expectations and point B after the change
b
The equilibrium will be at point A before the change in expectations and point B after the change
c
The equilibrium will be at point A before the change in expectations and point E after the change
d
The equilibrium will be at point E before the change in expectations and point A after the change

In the long run, as a result of the sharp increase in saving, the price level (remains the same, increases, decreases), the quantity of output (rises above, falls below, returns to) potential output, and the unemployment rate (rises above, falls below, returns to) the natural rate of unemployment.arrow_forward
- Consider the three theories of the upward slope of the short-run aggregate-supply curve. According to the sticky-wage theory, the economy recovers from a recession as nominal wages are adjusted so that real wages . True or False: According to the sticky-price theory, the economy is in a recession because people expect prices to rise quickly in a recession. True False True or False: According to the misperceptions theory, the economy is in a recession when the price level is above what was expected. True Falsearrow_forwardIf a recessionary gap occurs in the short run, then in the long run a new equilibrium arises when input prices and expectations adjust downward, causing the short-run aggregate supply curve to shift downward and to the right and pushing equilibrium real GDP per year back to its long-run value. The Federal Reserve can eliminate a recessionary gap in the short run by undertaking a policy action that increases aggregate demand. Which of the following is one monetary policy action that could eliminate the recessionary gap in the short run? A. The Fed can increase the money supply through an open market purchase of Treasury securities. B. The Fed can lower taxes. C. The Fed can increase the money supply through an open market sale of Treasury securities. D. The Fed can decrease the money supply through an open market purchase of Treasury securities.arrow_forwardExplain the likely effects of a U.S. boom on the demand for Canadian exports.
