Summary. This paper presents a general procedure for finding profiles with the minimum number of voters required for many important paradoxes. Borda's and Condorcet's classic examples are revisited as well as generalizations. Using Saari's procedure line, we obtain an upper bound for the minimum number of voters needed for a profile for which the Condorcet winner is not strictly top ranked for all weighted positional procedures. Also we give a simple upper bound on the minimum number of voters needed for a set of prescribed voting outcomes. In contrast to situations wherein small numbers of voters are needed, we consider paradoxes requiring arbitrarily large numbers of voters as well as large numbers of alternatives. Finally we indicate connections with statistical rank based tests. Received: April 18, 2001; revised version: May 25, 2001  相似文献

This article provides evidence on the determinants of royaltiesand upfront fees in share contracts by examining how state franchisetermination laws affect franchise contracts. The results areconsistent with the joint hypothesis that the two-sided moralhazard model explains the terms in franchise contracts and thattermination laws increase the relative importance of franchisoreffort (due to the extra effort that is required to controlsystem quality). I find that franchise companies that are headquarteredin termination-law states charge significantly higher royaltyrates than companies headquartered in other states (around 1%higher). Correspondingly, the initial franchise fees are lowerfor companies headquartered in termination states. Overall,franchisees appear to pay a higher price for franchises in stateswith protection laws. Consistent with a basic tenet of law andeconomics, price adjustments appear to offset at least someof the transfers that would otherwise be implied by the laws.  相似文献

This paper addresses the welfare consequences of applying the Ramsey rule when the regulated firm is not a monopolist in all of its markets. The partially regulated optimum and the outcome of myopic regulation, the Short-Sighted Ramsey Equilibrium (SSRE), are examined in a differentiated duopoly model. In the optimum, the markup of competitive substitute goods is relatively high. In the SSRE, the regulator is likely to set the price of competitive substitute goods lower than optimal, and complementary goods higher than optimal. Strategic reactions by a competitor may reverse the result.I thank Kenneth Train, Michael Crew (the editor), seminar participants at the University of California, Berkeley, and an anonymous referee for comments and suggestions.

We put a new set of shoes on that old workhorse, the competitive talent market (CTM) model in sports economics. There exist unique rational expectations equilibria for both national football league (NFL‐type leagues) and major league baseball (MLB‐type leagues) under the CTM model. A cursory statistical test fails to reject the empirical implications for the NFL‐type league. The model also suggests empirical tests of whether or not talent demand (marginal revenues from talent), including induced effects, actually slopes down. But like all models, the competitive talent model should be applied in its context. It describes highly cooperative North American sports leagues that have a wealth of common information. But it may not do the same for other leagues if they lack this common information.  相似文献

We study the representative consumer's risk attitude and efficient risk-sharing rules in a single-period, single-good economy in which consumers have homogeneous probabilistic beliefs but heterogeneous risk attitudes. We prove that if all consumers have convex absolute risk tolerance, so must the representative consumer. We also identify a relationship between the curvature of an individual consumer's individual risk sharing rule and his absolute cautiousness, the first derivative of absolute risk-tolerance. Furthermore, we discuss some consequences of these results and refinements of these results for the class of HARA utility functions.  相似文献

Significant increases in atmospheric carbon dioxide are occuring as a result of fossil fuel combustion. More than a four-fold increase over preindustrial levels may occur by the year 2100. Heating of the atmosphere, changes in precipitation patterns and global storm paths, and other resulting effects are sure to cause significant social changes. This article is essentially a methodological case study demonstrating a useful but inexpensive type of technology assessment. It summarizes current research findings on “the CO2 effect,” and presents hitherto unpublished findings that resulted from a brief but systems-oriented approach. These findings suggest that most published forecasts of phenomena associated with a CO2 buildup may be systematically low because various positive feedback relationships are not reflected.  相似文献

Good News and Bad News: Search from Unknown Wage Offer Distributions   总被引:1,自引:0,他引:1  
The largest market in national economies is the labor market. Labor market contracting is characterized by job search, often from unknown wage offer distributions. This paper reports experimental tests of finite horizon models of job search in which the wage offer distribution is unknown. Theoretically-optimal search from an unknown wage offer distribution can have the seemingly paradoxical property that some offers will be accepted that are lower than other offers that will be rejected in the same period of the search horizon. Thus the reservation wage property (or lowest acceptable wage path) may not exist. This can occur because an offer that is a priori relatively high (good news) can imply that it is highly probable that search is from a favorable distribution, and such an offer can look unattractive when it is an a posteriori relatively low offer from a favorable distribution (bad news). This paper reports results from experimental treatments for search from unknown distributions in which the reservation wage property does exist and treatments in which it does not exist. We find that the consistency of search behavior with search theory reported in earlier papers is robust to the presence or absence of the reservation wage property and to whether the draws come from known or unknown distributions.  相似文献

An Empirical Look at Software Patents   总被引:4,自引:1,他引:4  
Software patents have grown rapidly in number and now comprise 15% of all patents. They are acquired primarily by large manufacturing firms in industries known for strategic patenting; only 5% belong to software publishers. The very large increase in software patent propensity over time is not adequately explained by changes in R&D investments, employment of computer programmers, or productivity growth. The residual increase in software patent propensity is consistent with a sizeable increase in the cost effectiveness of software patents during the 1990s, perhaps arising from changes in the application of patent law to computer software.  相似文献

Abstract

Organizational justice research tends to focus on the effects of fair treatment from organizations or supervisors on employee attitudes and behaviors. Thus, there is a dearth of research on the effects of fair treatment attributable to other parties that employees interact with at work such as coworkers and clients. Controlling for organization-focused and supervisor-focused justice, results from our field study of employees working in a healthcare organization demonstrate that perceptions of client-focused fairness uniquely predicts supervisor ratings of employees organizational citizenship behavior toward clients and that perceptions of workgroup-focused justice uniquely predicts organizational citizenship behavior toward workgroups. Further, we find that client-focused justice perceptions uniquely predict employee turnover intention.  相似文献
