Synopsis This paper is the product of a collaboration between a biologist (Ghiselin 1997) who works on the philosophy of classification
and an economist (Landa 1981, 1994) who works on the ‘Economics of Identity’: how and why people classify people based on
identity in the context of a theory of ethnic trading networks. In developing the ‘bioeconomics’ (the synthesis of economics
with biology) of classification, we crossed a number of disciplinary boundaries—anthropology, economics, sociology, biology,
and cognitive psychology including evolutionary psychology’s ‘fast and frugal’ heuristics. Using a bioeconomics approach,
we argue that folk classifications—the classifications used by ordinary persons—have much in common with scientific classifications:
underlying both is the need for economy of information processing in the brain, for the efficient organization of knowledge,
and for efficiency of information acquisition and transmission of information to others. Both evolve as a result of trial
and error, but in science there is relatively more foresight, understanding, and planning. 相似文献

We survey managers of Nasdaq firms that consistently pay cash dividends to determine their views about dividend policy, the
relationship between dividend policy and value, and four common explanations for paying dividends. The evidence shows that
managers stress the importance of maintaining dividend continuity and widely agree that changes in dividends affect firm value.
Managers give the strongest support to a signaling explanation for paying dividends, weak to little support for the tax-preference
and agency cost explanations, and no support to the bird-in-the-hand explanation. The study provides new evidence about how
managers view dividend life cycles and residual dividend policy.

Let X (r, n, m, k), 1 r n, denote generalized order statistics based on an absolutely continuous distribution function F. We characterize all distribution functions F for which the following linearity of regression holds
E(X(r+l,n,m,k) | X(r,n,m,k))=aX(r,n,m,k)+b.We show that only exponential, Pareto and power distributions satisfy this equation. Using this result one can obtain characterizations of exponential, Pareto and power distributions in terms of sequential order statistics, Pfeifers records and progressive type II censored order statistics.

Regulatory decisions often must be made in an atmosphere of uncertainty, and arguments presented by the affected parties frequently
add to, rather than resolve, that uncertainty. Here, we examine several of the deregulatory decisions affecting the long-distance
market that were rendered by the FCC over the two-decade period following the divestiture of AT&T. Our purpose is to provide
empirical evidence relevant to some of the arguments regarding market conditions that were presented during that period. Findings
suggest that some of the more prominent allegations are not supported by the data.

In this paper I analyze the impact of regulatory policy on prices and demand for mobile telecommunications services across the European Union. I estimate a reduced form model of the mobile industry using panel data for the EU countries from 1998 to 2002. Among others, I find the following effects: liberalization of fixed telephone lines has a negative impact on prices and a positive impact on the demand for mobile services, and the introduction of mobile number portability has a negative impact on prices.*I am grateful to Toker Doganoglu, Gerd Hansen, Eric Kodjo Ralph, Guido Friebel, participants at the 30th EARIE Conference 2003, the 2nd International Industrial Organization Conference 2004 and the 19th Annual Congress of the EEA 2004, and anonymous referees for valuable comments. I would like to acknowledge the generous financial support from the Volkswagen Stiftung and the Munich Graduate School of Economics which made this research possible. All errors are mine.1 Source: European Commission (1994). 相似文献

Fiscal competition in space and time 总被引:1,自引:0,他引:1

This paper analyzes fiscal competition among numerous spatially-separated jurisdictions in an explicitly dynamic framework. The degree of factor mobility between jurisdictions is imperfect because it is costly and time-consuming to adjust factor stocks. Even if it is harmful in the long run, taxation of mobile factors redistributes income in favor of the owners of immobile resources in the short run. The locally-optimal tax on mobile factors is lower, the faster the speed with which factors adjust to fiscal policy. Anticipated taxes are less beneficial than those that can be imposed unexpectedly. 相似文献

Motivated by problems of coordination failure in organizations, we examine how overcoming coordination failure and maintaining
coordination depend on the ability of individuals to observe others’ choices. Subjects’ payoffs depend on coordinating at
high effort levels in a weak-link game. Treatments vary along two dimensions. First, subjects either start with low financial
incentives for coordination, which typically leads to coordination failure, and then are switched to higher incentives or
start with high incentives, which usually yield effective coordination, and are switched to low incentives. Second, as the
key treatment variable, subjects either observe the effort levels chosen by all individuals in their experimental group (full
feedback) or observe only the minimum effort (limited feedback). We find three primary results: (1) When starting from coordination
failure the use of full feedback improves subjects’ ability to overcome coordination failure, (2) When starting with good
coordination the use of full feedback has no effect on subjects’ ability to avoid slipping into coordination failure, and
(3) History-dependence, defined as dependence of current effort levels on past incentives, is strengthened by the use of full
feedback.

Summary. We consider the class of (finite) spatial games. We show that the problem of determining whether there exists a Nash equilibrium in which each player has a payoff of at least k is NP-complete as a function of the number of players.Received: 15 September 2002, Revised: 9 March 2003, JEL Classification Numbers:
