Donald G. Saari 《Economic Theory》1992,2(3):359-388
Summary Two theorems are given; the first extends the Sonnenschein-Mantel-Debreu theorem characterizing aggregate demand functions from the set ofn2 commodities to all of the 2
n
–(n+1) subsets of two or more commodities. The second theorem concerns spatial voting models for k2 candidates over a space of n2 issues. The theorem characterizes the sincere elecion rankings of thek candidates over all of the 2
n
–1 subsets of one or more issues. Both theorems have the same kind of conclusion; anything can happen. By demonstrating the mathematical reasons for these conclusions and by recalling related, recent results from statistics, voting, and economics, it is argued that this anything can happen conclusion is the type one must anticipate for aggregation procedures; particularly for the processes commonly used in economic models where the procedure is responsive to changes in agents' preferences, changes in data, etc.I am pleased to acknowledge conversations with L. Hurwicz, A. Mas-Colell and C. Simon about this material. In particular, I want to thank J. Jordan for his several helpful suggestions. Also, I benefited from comments made at meetings and seminars where these results were presented; this includes a June, 1990, conference in Stockholm, Sweden. Some stylistic suggestions were made by Arvid and Padon Kalinen. This research was supported, in part, by NSF Grant IRI-8803505. 相似文献

This article derives a model of airline services as joint goods. Using this model, the article shows how the existence of higher fares in certain hub routes may imply the market has generated a solution to the problem of covering joint costs by having a larger proportion of those costs come from hub routes, rather than the existence of any general market failure. The model is then used to make recommendations for competition policy. 相似文献

George G. Brenkert 《Journal of Business Ethics》1992,11(7):515-521
In a recent important book,The Ethics of International Business, Tom Donaldson argues that multinational corporations (as well as individuals and nationstates) must, at a minimum, respect international human rights. For a purported right to be such a fundamental right it must satisfy three conditions. Donaldson calls the third condition the fairness-affordability condition. The affordability part of this condition holds that moral agents must be capable of paying for the burdens and responsibilities that a proposed human right would impose. If this is impossible, then the purported right is not an international human right.I argue that Donaldson's affordability condition is subject to four objections which reveal its untenability as one of the conditions upon which identification of international human rights must rest. I offer another way of treating problems of affordability and capability when it comes to such rights that all moral agents must respect.George G. Brenkert is Professor of Philosophy at the University of Tennessee/Knoxville. He has recently completed a book,Political Freedom, to be published by Routledge. His current research focuses on issues in business ethics. 相似文献

Through the development and extension of theories and scholars’ subsequent empirical analyses of significant, theoretically grounded research questions, the knowledge about corporate entrepreneurship (CE) and its successful use continues to advance. Moreover, the literature suggests important relationships between the corporate environment, managers’ entrepreneurial behavior and successful implementation of corporate entrepreneurship actions. In an attempt to test some of those relationships, we describe an empirical study of 523 managers that examines the relationships among the antecedents to managers’ entrepreneurial behavior, a decision to implement entrepreneurial actions, and resulting job satisfaction and reinforcement practices. 相似文献

A bstract . Even the most passionate defenders of free trade, such as Mises and Rothbard, claim that trade cannot occur under conditions of strict homogeneity of land, labor, and capital. We show that specialization, trade, and the division of labor can emerge even when resources are initially homogenous, due to "natural heterogeneity," economies of scale, and learning. 相似文献

A versatile and robust metric entropy test of time-reversibility,and other hypotheses 总被引:1,自引:0,他引:1
We examine the performance of a metric entropy statistic as a robust test for time-reversibility (TR), symmetry, and serial dependence. It also serves as a measure of goodness-of-fit. The statistic provides a consistent and unified basis in model search, and is a powerful diagnostic measure with surprising ability to pinpoint areas of model failure. We provide empirical evidence comparing the performance of the proposed procedure with some of the modern competitors in nonlinear time-series analysis, such as robust implementations of the BDS and characteristic function-based tests of TR, along with correlation-based competitors such as the Ljung–Box Q-statistic. Unlike our procedure, each of its competitors is motivated for a different, specific, context and hypothesis. Our evidence is based on Monte Carlo simulations along with an application to several stock indices for the US equity market. 相似文献
