a. Draw two IS–LM graphs side by side, one for each country, to show the impact of
the policy on the two countries. Draw the relevant BP=0 curve and name all the
curves and axes on the graphs above. Name the original equilibrium point a for
Germany and a* for France.
b. Show the effect of the policy described above and the adjustment on the graph.
Show the initial world (= Germany+France) interest rate as i and the final world
interest rate as i¢. Show all the shifts of the relevant curves in the two countries and
the final two-country equilibrium (as respectively A and A*) as Y¢G and Y¢¢F.
c. What do you expect the impact to be on the German DM? On the French franc?
d. What happens to the interest rate in the two countries eventually (from the original
to the final situation)? And to income in each country?
Now let us start from this new equilibrium (the new interest rate is now i¢ and the
new equilibrium income are Y¢G and Y¢F) and figure out what will happen when
Germany uses monetary policy to fend off inflation.
e. Use a new set of graphs – one for each country. Draw the relevant BP¢ curve at
interest rate i¢ and name all the curves and axes on the graphs above. Name the
original equilibrium point A for Germany and A* for France. Show the effect of the
policy described above and the adjustment on the graph. Show the initial world
interest rate as i¢ and the final world interest rate as i¢¢. Show all the shifts of the
relevant curves in the two countries and the final two-country equilibrium.
f. What do you expect the impact to be on the German DM? On the French franc?
g. What happens to the interest rate in the two countries eventually (from the situation
in b to the final situation)? And to income in each country?
5. Switzerland adheres to a flexible exchange rate arrangement and allows very high to
perfect levels of capital mobility. Unfortunately their economy is in a slump and their
currency is too strong for the good of their economy. The exchange rate of 1.60 SF per
euro overestimates the health of the Swiss economy. An exchange rate of 1.66SF per
euro would be a better reflection of the Swiss fundamentals. Two problems need to be
tackled at once with two policies.
a. Draw a graph showing the internal balance and the external balance as two lines in
a space measuring, on the vertical axis, monetary policy as the level of interest rate
i and, on the horizontal axis, fiscal policy as the level of government spending G.
Show the position of the Swiss economy on the graph.
b. Suggest the correct assignment to restore both internal and external balance. Show
the path on the graph.
6. In the mid 1990s, the Irish economy was at full employment. However since Ireland
was planning to join the EMU, Ireland had a fixed exchange rate arrangement with the
other members and had to follow its cue from the European Monetary Institute (EMI),
the European organization that was harmonizing the monetary policy of the members.
Most of the other members had sluggish economies so monetary expansion was the
policy advocated.
a. What was the impact of the policy in the short run for Ireland?
b. Use the AD–AS diagram to show the effect of the policy on prices in Ireland in the
medium run.
