Aggregate Demand and Aggregate Supply - End of Chapter Problem
A fall in the value of the dollar against other currencies makes U.S. final goods and services cheaper to foreigners, even though
the U.S. aggregate price level remains the same. As a result, foreigners demand more U.S. aggregate output. Your study
partner says that this represents a movement down the aggregate demand curve because foreigners are demanding more in
response to a lower price. You, however, insist that this represents a rightward shift of the aggregate demand curve.
Currency crises and the demand for dollars: Suppose there is a currency crisisin the rest of the world, leading to an increase in demand for U.S. dollars (a“fight to safety”). Use the AS/AD framework to explain the efects of thisshock on the U.S. economy. Be sure to explain carefully how and why theshock enters the AS/AD model. (Hint: If the rest of the world would likemore dollars, what does it have to give in exchange for those dollars?
Consider the relationship among exchange-rate changes, aggregate demand, and monetary policy. Assume we begin in a situation with real GDP equal to Y∗.Y*.
Suppose the world price for raw materials rises because of growing demand for these products. Given that Canada is a net exporter of raw materials, what is the likely effect on Canadian aggregate demand? Show this in an AD/AS diagram (assuming no change in the exchange rate).
Suppose instead that there is an increase in the demand by foreigners for Canadian financial assets such as government bonds. What is the direct effect on Canadian aggregate demand? Show this in an AD/AS diagram (assuming again no change in the exchange rate).
Both of the shocks described above are likely to cause an appreciation of the Canadian dollar on foreign-exchange markets. As the Canadian dollar appreciates, what are the effects on aggregate demand in part (a) and in part (b)? Show these “secondary” effects in your diagram and explain.

Country A is an oil exporting country. The aggregate demand and supply functions are given as below: AD : Y = 710 − 30P + 5G+3Poil AS : Y = 10 + 5P − 2Poil where Y is real GDP, P is the price level, G is the government purchases, and Poil is the world price of oil. Write down the equilibrium condition. Solve for the equilibrium value of real GDP and the price level (hint: take G and Poil as known variables).
