and the implied prices of nontrade goods.) The relative higher purchasing power of . is sustained and maintained by its considerably higher productivity in services. Because most of those services are nontraded, Japanese could not benefit from those lower service costs. And . does not have to face a lower international price of services. So the purchasing power of Japanese is just onethird of their . counterparts.9.How does the fact that many goods are nontraded affect the extent of possible gains from trade? Actually the gains from trade depended on the proportion of nontraded goods. The gains will increase as the proportion of nontraded goods decrease. 10.We have focused on the case of trade involving only two countries. Suppose that there are many countries capable of producing two goods, and that each country has only one factor of production, labor. What could we say about the pattern of production and in this case? (Hint: Try constructing the world relative supply curve.) Any countries to the left of the intersection of the relative demand and relative supply curves export the good in which they have a parative advantage relative to any country to the right of the intersection. If the intersection occurs in a horizontal portion then the country with that price ratio produces both goods. 6
