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).
What effects would each of the following have on aggregate demand or aggregate supply? Justify your answer. In each case use a diagram to show the expected effects on the equilibrium price level and real output level in the economy. Assume that all other things remain constant and prices are inflexible downward.

(b) A sizable increase in labor productivity.
(c) The nation’s currency appreciates against its major trading partners .
