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 countrys exports increase. This would, logically, lead to a shift away by world consumers to substitute goods. If the demand for a countrys 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 countrys real income and economic welfare.2.If a countrys growth is biased in favor of its import, this should unequivocally improve its terms of trade and its economic welfare. Discuss.Answer:Suppose Japan experiences economic growth biased in favor of its import substitutes. For example, assume that Japan imports components and exports final goods, but that it experiences a major growth in its components manufacture sector. Since Japan is internationally a large country in these markets, this would tend to hurt its component suppliers terms of trade (and help Japans). However, such a bias in economic growth may tend to lessen the volume of international trade. At an extreme, Japan may become an exporter of components and an importer of final goods. If the result is a lessening of specialization and of the volume of trade, then this effect will lower Japans welfare associated with gains from trade. If an actual change in the pattern of comparative advantage occurs (a possibility) this may cause dynamic dislocations whose harm overpowers static gains for a relatively long period of time.3.It is impossible for economic growth in a small country to lower that countrys economic welfare, regardless of the bias of the growth. Explain.Answer:This is a true statement. The reason economic growth may hurt a country is if the terms of trade effect counters and dominates the growth effect. In the case of the small country there is no terms of trade effect.4.At the conclusion of World War I, Germany, as a punishment, was obliged to make a large transfer to France in the form of reparations. Is it possible that the actual reparations may have improved Germanys economic welfare?Answer:Such a result is not likely. However, theoretically, if Frances income elasticity of demand for Germanys exports was higher than Germanys income elasticity of demand for its own exportable, then the real income transfer associated with these reparations may have improved Germanys terms of trade, and improved its balance of payments, thus helping Germany in manner unanticipated in the Treaty of Verssaille. Explain.5.An export subsidy has the opposite effect on terms of trade to the effect of an import tariff. Domestically a tariff will raise the price of the import good, deteriorating the domestic terms of trade. A production subsidy for the export product will lower the local price of the export good, lowering the domestic terms of trade for the country. Hence the export subsidy and the import tariff have the same effect. This analysis seems to contradict the first sentence in this paragraph. Discuss this paradox.Answer:While this (Lerner) equivalence may well occur domestically, internationally the tariff will improve a c
