Japanese input coefficients are used to investigate the pattern of comparative advantage in the exportation of manufactured products in a cross-country framework. Estimates are made for the imports of manufactured products as well as for net exports. Also, alternative techniques of estimation are utilized and an attempt to explain the residuals in the regression equations and to indicate the predictive power of these equations is made. The paper shows that patterns of comparative advantage in manufactured goods can be explained by reference to commodity characteristics and country characteristics. In turn, intercountry differences in the extent of trade orientation, the concentration of exports, and foreign direct investment explain part of the residuals of the cross-country regression equations. Finally, it has been found that the method applied permits projecting the factor intensity of trade for individual countries.

T HIS paper analyzes the changing pattern of comparative advantage in manufactured goods in the process of accumulation of physical and human capital that characterizes economic development. Section I of the paper describes the model to be estimated while section II defines the explanatory variables employed. The empirical results are presented in section III, and the policy implications of the results are analyzed in section IV.

E CONOMIC theory can be regarded as consisting of a number of models designed to explain economic phenomena and to yield predictions for the future. Any choice among alternative models should be based on their explanatory valuea model (or hypothesis) can be regarded as superior to another if it better explains actual phenomena and it is more helpful in predicting future events. theory of international trade abounds in theoretical models, some of them complementary, others conflicting. Alternative approaches towards explaining the causes of international specialization are followed, for example, by classical economists on the one hand, and by Heckscher and Ohlin on the other. While the hypothesis advanced by the former presupposes the existence of inter-country differences in production functions, the latter assume identical production functions and qualitatively identical factors of production in the trading countries and attribute international specialization to differences in factor endowments. empirical testing of the Heckscher-Ohlin hypothesis by Leontief led to inconclusive results, and the interpretations and explanations given to the Leontief paradox have demonstrated that the assumptions of this model require modification.' In the present paper, we will not attempt to test the Heckscher-Ohlin hypothesis, but will rather inquire into the validity of the classical model. According to the original formulation of the classical theory, comparative advantage based on relative productivity differentials determines international specialization. It has subsequently been realized that inter-country differences in the wage structure and in the capital-labor ratios of various industries may compensate for productivity differentials; a country possessing a relative productivity advantage in a particular industry may still import the commodity in question if it paid relatively higher wages and/or had higher capital costs per unit of output in that industry.2 Still, the defenders of classical theory among others, Taussig expressed the opinion that the latter factors are not sufficiently important to warrant significant changes in the trade pattern as determined by relative differences in productivity.3 Let us adopt the following notation: C= unit cost A = labor input per unit of output W wage rate T ratio of capital plus labor costs to labor costs Subscripts I and II refer to country I and country II, respectively.
