Knowledge that Transforms

T HE of a country in world is understood conventionally as the ratio of the country's to world trade. For a few important purposes, however, this concept is inadequate. This is the case, for example, in considering the relation between the in world and the monopolistic or monopsonistic power of nations, or the effects of the size of a country's on its proper course of development or on the probable outcome of a devaluation, to name a few.' The purpose of the present study is to define a more appropriate concept of share in world trade for these occasions, to measure it for as many countries as possible, to distinguish its components, and to discuss major factors by which they are affected.
