In the short-run, any fall in EP/P, regardless of its causes, will causeA) an upward shift in the aggregate demand function and an expansion of outputB) an upward shift in the aggregate demand function and a reduction in outputC) a downward shift in the aggregate demand function and an expansion of outputD) an downward shift in the aggregate demand function and a reduction in outputE) an upward shift in the aggregate demand function but leaves output intact9. In the short-run, a temporary increase in money supplyA) shifts the DD curve to the right, increases output and appreciates the currency.B) shifts the AA curve to the left, increases output and depreciates the currency.C) shifts the AA curve to the left, decreases output and depreciates the currency.D) shifts the AA curve to the left, increases output and appreciates the currency.E) shifts the AA curve to the right, increases output and depreciates the currency.10. Temporary tax cuts would cause:A) the AA-curve to shift left.B) the AA-curve to shift right.C) the DD-curve to shift left.D) the DD-curve to shift right.E) a shift in the AA-curve, although the direction is ambiguous.11. In the short-run, a temporary increase in the money supplyA) shifts the AA curve to the right, increases output and depreciates the currency.B) shifts the AA curve to the left, increases output and depreciates the currency.C) shifts the AA curve to the left, decreases output and depreciates the currency.D) shifts the AA curve to the left, increases output and appreciates the currency.E) shifts the AA curve to the right, increases output and appreciates the currency.12.

Therefore a fall in Y would result in:A) higher inflation abroad.B) a decreased demand for domestic products.C) a contraction of the money supply.D) a depreciation of the home currency.E) an appreciation of the home currency.13. What can explain the failure of relative PPP to hold in reality? Government measures of the price level differ from country to country. One reason for these differences is that people living in different countries spend their income in different ways. Because of this inherent difference among countries, certain baskets will be affected more by price changes given their consumptions basket. For example, consumers in country, X, eats more fish relative to another country. More than likely, the government, upon determining a commodity basket to reflect preference, will have an overwhelming representation of fish in their basket. Any price level change in the fish market will be felt particularly by country X, and their overall price level will reflect this. Thus, changes in the relative prices of basket components can cause relative PPP to become distorted.14. Using a figure show that under full employment, a temporary fiscal expansion would increase output (overemployment) but cannot increase output in the long run. A temporarily fiscal expansion will move the economy from DD1 to DD2, and output increases. A permanent fiscal expansion will also shift the AA curve to the left and down. The nominal exchange rate appreciates, i.e. E decreases.15. Using
