Answer: A Essay Questions 1. Other things being equal, a rise in a country’s terms of trade increases its welfare. What would happen if we relax the ceteris paribus assumption, and allow for the law of demand to operate internationally? Answer: Let us assume that the terms of trade (or technically the net commodity terms of trade) improve, thus the relative price of a country’s exports increase. This would, logically, lead to a shift away by world consumers to substitute goods. If the demand for a country’s exports is elastic, the quantity decrease would be proportionally larger than the per unit price increase. This term of trade effect would actually lower the country’s real income and economic welfare.
If a country’s growth is biased in favor of its import, this should unequivocally improve its terms of
Suppose Japan experiences economic growth biased in favor of its import substitutes. For
It is impossible for economic growth in a small country to lower that country’s economic welfare,

suggest?
An “improvement” in the terms of trade occurs when the price of a country’s exports rises
Quantitative/Graphing Problems 1. Albania refused to engage in international trade for ideological reasons. To maximize its economic welfare it would choose to produce at which point in the diagram above? Suppose the PA/PB at point a was equal to 1. Given this information, in which good (A or B) does Albania enjoy a comparative advantage? Now that the Cold War is over, Albania is interested in obtaining economic welfare gains from trade. The relevant international relative price is PA/PB 2. Albania would therefore choose to produce at which point (a, b, or c)? Given this additional information, in which good does Albania enjoy a comparative advantage? Answer: Albania would choose to produce at point a. With no reference to world terms of trade, one cannot establish Albania’s comparative advantage. Later, when Albania discovers that the relative price of A equals twice the price of B, it knows that it has a comparative advantage in A. Therefore Albania would produce at production point b. 2. Now, suppose that the relative price of A is actually not higher than Albania’s autarkic level of 1, but quite the opposite (e.g. PA/PB 0.5). Would Albania still be able to gain from trade? If so, where would be its production point? Given the information in this question, where is Albania’s comparative advantage? Answer: Yes. As long as the world’s terms of trade differed from those of Albania, that country stands to gain from international trade. In this particular case, its point of production with trade would be at point c.

5. Suppose Albania is exporting product B, and experienced economic growth biased in favor of product B as seen in the Figure above. We are also told that Albania’s new consumption point is at point d. Would you still consider the economic growth, which took place biased in favor of B? If Albania were a large country how would this growth affect its terms of trade? Answer: This is a relatively difficult case. On the one hand, the growth is still technically export biased. However, Albania’s consumption clearly shifted in favor of its import product, A. In this case, the

deterioration in the terms of trade would be much more pronounced than before, and may lead to a case of immiserizing growth. However, for this to occur, there must have been a major shift in the taste patterns (the old community indifference map is not longer applicable). Therefore, when we try to judge the direction and magnitude of the welfare change, we are comparing the old versus new taste preferences, which raises the classic index number problem.
