This paper examines the impact of foreign management as a separate input in a competitive economy open to both international trade and international movement of productive capital. Three inputs (capital, labor, management) are used to produce two final goods in a model characterized by competition, homogeneous products, and full employment. This model provides a simple starting point for the study of multinational firm activity, building on the fundamental competitive factor proportions model of production and trade. A clear distinction arises between international movements of capital and management, and international movements of the two inputs are linked. [F 11, F 23]  相似文献

A generic characterization of the dynamics of market penetration by technological artifacts is here formulated on the basis of entry rate and exit rate considerations. It is shown that low-order reductions lead to the biologically based logistic dynamic, which—by empirical fit—has been found to be in very good agreement with numerous specific cases. In addition to the derivational justification of the logistic for artifact market penetration, we find that but a small number of parameters are involved in these autonomous characterizations suggesting therefore that market penetration may well be reduced to a similarly small number of dominant operative processes. Some nonautonomous extensions are also discussed.  相似文献

This paper suggests a technology forecasting approach based on a semi-Markov model, which appropriately describes the probabilistic nature of a sequential technology development process. This approach focuses primarily on the utilization of the information that has been skipped in conventional Delphi survey data. That is, through a simple statistic, the interrelationships among sequential technology developments can be extracted in a formal structure of a semi-Markov model from the original Delphi panel's estimates. A simulation technique is developed to forecast the development process by utilizing the information on such interrelationships. This technique provides a flexible and useful tool for R&D planners or project managers, especially in postanalysis of Delphi forecasting. To make good use of the approach, a computer-based interactive Delphi data analysis system (IDEAS) is implemented in IBM PC.  相似文献

Our analysis focuses on the effect of U.S. government pressure on Korea to adopt product patents for chemical and pharmaceutical products. American pressure began in November 1985 and ended with the Korean Legislature's passage of a new patent law in December 1986. We conduct an event study of the effect of the new patent law on the value of Korean pharmaceutical firms listed on the Korea Stock Exchange. Regression analysis shows that the new law induced excess returns of-74 percent over the 14-month analysis period. The results suggest that adoption of stronger patent laws reduced Korea's wealth.

This paper studies the time-series behavior of consumption in a model that incorporates birth, death, and a precautionary motive for saving. Consumption of an individual agent is a random walk. However, aggregate consumption is a random walk if and only if the sum of the death rate and population growth rate is zero. Failure of the random walk hypothesis should not be attributed to finite horizons perse, but rather to inter-generational transfers caused by birth and death. Unlike certainty-equivalent models, the expected growth of consumption depends on financial wealth, rather than wage income or human capital. [D91, E21]  相似文献

The paper analyses the roles of financial factors in the behavior of M1 and M2 demands for Malaysia. The focus is on the possible changes in the elasticities of the M1 and M2 money demands in the environment of financial innovations and on the influence of real stock prices on the holdings of monetary assets. Our results reinforce existing studies that find the presence of the long-run M1 and M2 money demands and structural instability in the dynamic specification of the M1 demand. However, we are able to identify stable error-correction model for the post-1986 M1 demand and for the M2 demand. Our results also indicate the reduction in the Long run income and exchange rate elasticities of the money demands. Meanwhile, the interest rate sensitivity of the demands becomes more inelastic. Lastly, we document the significance of real stock prices in influencing the demand behavior, indicating the dominance of the wealth effect over the substitution effect. [E41, E44]  相似文献

Abstract

This article examines the cultural field of fitness as a network of producers, consumers, products and practices that has developed around the care of the body through physical exercise. Drawing on a thematic text analysis of US exercise manuals, the paper focuses on how the commercial fitness field naturalizes associations between physical exercise and leisure, and between leisure and self‐work. In particular, the analysis examines three themes and their relevance to our broader understanding of leisure in contemporary consumer society: the management of leisure time; the use of leisure for self‐investment strategies; and the promotion of consumption as the framework for leisure and an accompanying notion of pleasure. The fitness field casts light on how leisure more generally is constructed as a sphere of obligations to make productive use of one’s time, to improve one’s body and self, and to do so through the wares of the consumer marketplace. The cultural imaginary of leisure as a time of freedom from work and responsibility is thus recast, in an age of individualization, as a time of freedom to accomplish the work of self‐production.  相似文献
