引文： THE theory of comparative cost has suffered several severe attacks in recent times. I shall consider two of these. (1) It has been denied that international trade is governed by the principle of comparative cost; and this not only in the sense that the terms of international exchange are not exactly determined — already Mill has pointed out that comparative costs fix only the limits and must be supplemented by another principle in order to locate the exact exchange rate within the limits — but in the sense that in international trade a stable equilibrium is thinkable and often realized, which contradicts the principle of comparative cost. The contention is that it may happen and does happen that a country exports commodities in which it has a comparative disadvantage, measured in labor costs or in any other way, and imports articles in which it has a comparative advantage; both without any forces being invoked (for example, specie flow or alterations of the foreign exchange rate) which would correct the situation in accordance with the comparative-cost principle.
