b. dollar wages rose but the price level rose by a larger percentage.

10) Suppose the money supply grows faster in Mexico than Canada. Other things constant,
a. the Canadian dollar will appreciate relative to the Mexican peso.
b. the Canadian dollar will depreciate relative to the Mexican peso.
c. the Canadian dollar will maintain constant value relative to the Mexican peso because of purchasing
power parity.
d. the Canadian dollar will maintain constant value relative to the Mexican peso because of the theory

Part 2: True/False questions (20 points)
Indicate CLEARLY whether the statement below is true or false, no need for explanation.
1) Frictional unemployment is often the result of changes in the demand for labor among different firms.
2) According to the theory of liquidity preferences, the long-run aggregate supply curve is upward sloping.
3) In the national income accounts, GDP can be measured as production, income, or expenditures.
4) In an open economy, when NCO (net capital outflow) increases, NX (next export) decreases.
5) The Crowding-Out Effect is the additional shifts in AD that result when fiscal policy increases income
and thereby increases consumer spending.
Part 3: Explanation of concepts (30 points)
Answer the following questions. Use graphs when necessary.
1) List three theories for why the short-run aggregate-supply curve is upward sloping and explain
only one of them.
2) Draw the AD-SRAS-LRAS diagram for the Czech economy staring in a long-run equilibrium.
Suppose that economic boom occurs in Germany. Use the diagram to determine the short run
and long run effects on the Czech GDP, the price level and unemployment.
3) Define the nominal exchange rate and real exchange rate and explain how they are related. If
the nominal exchange rate goes from 100 to 120 yen per dollar, has the dollar appreciated or
depreciated?
Part 4: Solve the problem (30 points)
Solve the following problem. Show your work, no points will be granted to solutions without
explanation.
Suppose the government reduces taxes by $20 billion, that there is no crowding out, and that the
marginal propensity to consume is 3/4.
a. What is the initial effect of the tax reduction on aggregate demand? Draw AS-AD diagram and
show the changes.
b. What additional effects follow this initial effect? What is the total effect of the tax cut on
aggregate demand?
c. How does the total effect of this $20 billion tax cut compare to the total effect of a $20 billion
increase in government purchases? Why?
