Summary. We prove that, for finitely many demand observations, the Strong Axiom of Revealed Preference tests not only the existence of a strictly concave, strictly monotone and continuous utility generator, but also one that generates an infinitely differentiable demand function. Our results extend those of previous related results (Matzkin and Richter, 1991; Chiappori and Rochet, 1987), yielding differentiable demand functions but without requiring differentiable utility functions.Received: 1 November 2001, Revised: 5 February 2004, JEL Classification Numbers:

This article examines the external shocks and subsequent adjustment processes in the Soviet Union, China, and Hungary during 1974–76, 1979–81, and 1984–87. It compares the experiences of the three socialist countries with regard to external shocks to those of inward-and outward-oriented groups of newly industrializing countries (NICs). In contrast to the NICs, terms of trade effects were of secondary magnitude to export demand effects of external shocks in the three socialist countries during the first two periods. The oil-exporting Soviet Union had beneficial terms of trade effects during the first two periods, with unfavorable effects coming only in the third period. The adjustment responses to the external shocks varied greatly in the Soviet Union from the other two reform-oriented socialist countries and from both groups of NICs. It is interesting to note that the types of responses in the Soviet Union were quite opposite to that one observes for market economies. However, reform-oriented China and Hungary seemed to have response patterns similar to those of market economies, though China's response was similar to the outward-oriented NICs, while Hungary's was similar to the inward-oriented NICs.The authors would like to thank two anonymous referees, as well as Robert Dernberger, Albert Fishlow, Gregory Grossman, Chung Lee, Michael Plummer, Laura Tyson, and Benjamin Ward, for useful comments on this paper. Research in preparing this study was partly supported by a grant from the Institute of International Studies and Center for Slavic and East European Studies of the University of California, Berkeley. 相似文献

The multiple objectives of perishable product inventory management are examined in this paper. These objectives include: (1) satisfying demand by carrying sufficient inventories, (2) holding down inventory carrying costs, (3) keeping the amount of product spoilage (outdating) at an acceptable level, and (4) maintaining quality by using the product while it is still fresh, and (5) keeping the cost of rotation low. Some of the above objectives are in conflict. Thus, certain redistribution policies may help attain one or more of these objectives to a greater extent. Redistribution involves the transfer of the product from outlets where demand is low to outlets where demand is high. A goal programming model for solving redistribution problems is presented. An example is provided and sensitivity analysis is performed in order to determine when redistribution is advantageous. Applicability of the model is discussed. 相似文献

Changes in the population age structure are known to influence the total income per person, but little is known about whether the changes are equally shared across the population or are concentrated on particular age groups and/or birth cohorts. The answer to this question has potentially important implications for income inequality, human capital investment, and fertility decision-making. We propose a new model of intergenerational transfers which distinguishes between the effects of changes in population structure and the effects of changes in family age structure. Using age-specific data from annual income and expenditure surveys of Taiwan between 1978 and 1998, we show that changes in age structure have had a very favorable effect on Taiwan's income growth. The gains are not equally shared by all age groups, however. Children and young adults have benefited the most, while the elderly have benefited the least. The population and family age structures have independent effects on per capita income; the effect of the population age structure is most important. Generational differences in per capita income are closely related to intergenerational differences in earnings, suggesting only a weak form of altruism. Finally, we predict that, on average, population aging will adversely influence the per capita income growth in Taiwan in the coming decades. 相似文献

Tourism resources are important foundation for the development of tourism industry. Grassland is not only a kind of important resource but also a great attraction to visitors. Therefore, the integrated development and sustainable utilization of grassland tourism resources are of great significance. This paper, based on the analysis of literatures and the current problems existing in grassland tourism, summarizes the speciality of grassland tourism development, deals with the problem of speciality, and raises the modes of regional development, product development and management. This paper takes Inner Mongolia, the famous grassland tourism destination as example and carries out empirical research. Based on the status quo of grassland tourism resources in Inner Mongolia, this study analyzes the character- istics of grassland tourism resources, the necessity and feasibility of integrated development, then proposes the following suggestions: idea for development, mode of development, regional cooperation, tourism products development, espe- cially the three modes of development based on the resources conditions - the mode of relying on market, the mode of combination aggregation and the mode of relying on quality. 相似文献
