A multisector computable general-equilibrium model for the Yugoslav economy is used to analyze some of the internal and external causes of the foreign-exchange crisis of the 1976–1980 period. Methodologically, its modeling approach, appropriately modified for institutional differences, can be used to study the behavior of socialist economies in which prices play a role in resource allocation. Empirically, the results suggest that internal policy errors and systemic factors were the predominant force behind Yugoslavia's growing foreign-exchange shortage between 1976 and 1980. J. Comp.

If David Ricardo had lived beyond the age of 51, how might he have delivered a lecture on comparative advantage? I argue that Ricardo infers the direction of comparative advantage and the size of the gains from trade by interpreting the four numbers in his Principles of Political Economy and Taxation for cloth and wine traded between England and Portugal as amounts of labor embodied in the quantities actually traded. He illustrates diagrammatically the gains from trade as the overall labor that England would save if it were to liberalize wheat imports by repealing the Corn Laws. Postulating a concave production function for wheat, Ricardo also depicts the concomitant rise in the profit rate, describing it as an equally important contemporary gain from trade for England. His interpretation differs radically from the textbook versions of the “Ricardian trade model,” and suggests a more authentic way of presenting the principle of comparative advantage. 相似文献

According to Becker [Becker, G., 1964, Human Capital, NBER, New York], when labour markets are perfectly competitive, general training is paid by the worker, who reaps all the benefits from the investment. Therefore, ceteris paribus, the greater the training wage premium, the greater the investment in general training. Using data from the European Community Household Panel, we compute a proxy of the training wage premium in clusters of homogeneous workers and find that smaller premia induce greater incidence of off-site training, which is likely to impart general skills. Our findings suggest that the Becker model provides insufficient guidance to understand empirical training patterns. Conversely, they are not inconsistent with theories of training in imperfectly competitive labour markets, in which firms may be willing to finance general training if the wage structure is compressed, that is, if the increase in productivity after training is greater than the increase in pay. 相似文献

This paper represents the attempt to define a methodology that can evaluate the degree to which companies' information systems correspond to needs determined by the objectives of sustainability the firm imposes on itself. The result is the creation of a general model which define the correct approach to evaluating information systems – a model which should be adapted to the specificity of each single company which intends to adopt it. In the chart indicated, we obviously have not considered activities connected to the implementation of the survey system, which are particular to each company's situation. The first part of the paper consists of an overall introduction to the approach that has been used to assess the (MIS) of Granarolo, one of the Italian companies involved. The case study contains a profile of the company, the analysis of its MIS referred to the three dimensions of sustainability, and an evaluation of the strong points and issues to be developed. This approach to evaluate the gap between desired requirements of an information system for sustainability and current data available in a firm, has proved its consistency and usefulness. It helps to understand where data are, which dimensions, spheres, stakeholders account for and what is the level of integration between different information systems existing in the firm. 相似文献

This paper discusses the occurrence of skill‐enhancing technology import, namely, the relationship between imports of embodied technology and widening skill‐based employment differentials in low‐ and middle‐income countries. Generalized method of moments (GMM) techniques are applied to an original panel dataset comprising 28 manufacturing sectors for 23 countries over a decade. Econometric results provide robust evidence of the determinants of widening employment differentials in low‐ and middle‐income countries. In particular, the proposed empirical evidence indicates capital–skill complementarity as a possible source of skill bias, while imported skill‐enhancing technology emerges as an additional driver of increasing demand for the skilled workers in these countries. 相似文献
