1) if e is the current spot rate (units of home currency per unit of foreign currency),
efwd is the current three-months forward rate, e(e) is the expected spot rate in three
months, and xa is the expected rate of depreciation of the home currency in three
months, then, in an efficient foreign exchange market,
a. e(e) = efwd
b. e = efwd
c. xa = efwd
d. e(e) = e
2) in the following classical-type table showing the output per 10-days of labor input in
each of the two commodities in each of the two countries,
a. germany has a comparative advantage in both goods
b. france has an absolute advantage in both goods
c. france has a comparative advantage in cameras
d. the pretrade price ratio in france is 1 wine = 2.5 cameras
3) given the following ricardo-type table showing the amount of labor input required to
produce one unit of output of each of the two goods in each of the two countries:
a. a post-trade price ratio (terms of trade) of 1 shirt:0.75 machine is a feasible post-trade
price ratio
b. a post-trade price ratio (terms of trade) of 1 machine:0.6 shirt is a feasible post-trade
price ratio and it would give all the gains from trade to france
c. a post-trade price ratio (terms of trade) of 1 machine:0.55 shirt is a feasible post-trade
price ratio and both countries would gain from trade at that price ratio
d. other things equal, if world demand for shirts is much greater than world demand for
machines, then the post-trade price ratio (terms of trade) will tend to settle toward or be
