Recent literature is sceptical about the ability of aquaculture development to enhance equity and reduce poverty. This article investigates the issue empirically by surveying 148 households randomly selected in five coastal communities of the Philippines. There is overwhelming evidence that aquaculture benefits the poor in important ways and that it is perceived very positively by poor and non‐poor alike. In particular, the poor derive a relatively larger share of their income from it than the rich, and a lowering of the poverty line only reinforces this result. A Gini decomposition exercise also shows unambiguously that aquaculture represents an inequality‐reducing source of income, providing employment to a large number of unskilled workers in communities characterised by large labour surpluses. 相似文献

A recent comparison of evolutionary, neural network, and scatter search heuristics for solving the p-median problem is completed by (i) gathering or obtaining exact optimal values in order to evaluate errors precisely, and
(ii) including results obtained with several variants of a variable neighborhood search (VNS) heuristic. For a first, well-known,
series of instances, the average errors of the evolutionary and neural network heuristics are over 10% and more than 1000
times larger than that of VNS. For a second series, this error is about 3% while the errors of the parallel VNS and of a hybrid
heuristic are about 0.01% and that of parallel scatter search even smaller. 相似文献

Much has been said and written about the influence (ideological as well as economic and political) of the advanced capitalist countries on the Third World. In this article, the author addresses the opposite question: What is the ideological influence of the South on the North? And he does it in a precise context: that of Quebec society during the sixties and seventies. He attempts to show that the underdeveloped world passed from the status of a new ‘pays de mission,’ during the early days of the Quiet Revolution, to that of a model for the radical nationalist left which emerged in the mid-sixties and exerted a definite influence on politics, unions, and the intellectual production of that period. His hypotheses are that 1/Third World Marxism - under its various forms, from Guevarism to Maoism - provided a language in which Quebec leftist intellectuals and activists represented to themselves the situation of the Quebecois in relation to English Canada and/or the United States and 2/ the nationalistic element included in these particular trends of Marxism is the critical factor which made it much more appealing than orthodox Marxist theory. The decline on both the national and the social fronts in the eighties made for a re-emergence of the old modernization model in a new guise. L'influence idéaologique, économique et politique qu'exercent les pays capitalistes avancés sur le Tiers-Monde a fait l'objet de nombreuses études. Dans cet article, l'auteur se pose la question inverse: Quelle est l'influence du Sud sur le Nord? Et il le fait dans un contexte précis: celui du Québec des années 60 et 70. II essaie de démontrer que le Tiers-Monde, qui conserva son statut de ‘pays de mission’ au début de la Révolution tranquille, devint par la suite un modèle pour la gauche nationaliste radicale qui émergea au milieu des années 60 et qui exerça une nette influence sur la politique, le syndicalisme et la production intellectuelle de cette période. Ses hypothèses sont les suivantes: 1/ le ‘marxisme du Tiers-Monde’ -sous ses formes variées (du guévarisme au maoïsme) - a fourni aux intellectuels et radicaux de l'époque un langage pour représenter la situation des Québécois, par rapport au Canada anglais et/ou aux Etats-Unis et 2/ l'élément nationaliste présent dans ce discours marxiste particulier a constitué l'élément-clef qui l'a 相似文献

We define a class of Nash based mechanisms that implement Lindahl allocations in standard public good economies. As those that first proved Nash implementation of Lindahl allocations, defined by Hurwicz (1979) and Walker (1981), the mechanisms provided here are continuous, feasible, and independent of agents' characteristics. In economies with two agents (e.g., bilateral monopolies, duopolies, principal-agent models), our mechanisms are also applicable, in contrast to the well-behaved mechanisms in the literature, and they satisfy favourable stability properties. 相似文献

Legislation allowing for some form of death prior to it naturally occurring presently exists in very few industrial democracies. This article explores what large-scale economic and social factors may be associated with the legality of right-do-die measures, namely, a nation's health care expenditures, the old-age dependency ratio, religious pluralism, and homicide and suicide rates. Using data from several sources, we find an association among these factors and right-to-die legislation. Four of the six countries with recent experience of legalized physician-aided death ranked in the top 50% of countries on our combined measure of the five factors under examination. Implications of this study and suggestions for future research of this timely issue are discussed. 相似文献

The identification of information problems in different markets is a challenging issue in the economic literature. In this paper, we study the identification of moral hazard from adverse selection and learning about risk within the context of a multi‐period dynamic model. We extend the model of Abbring, Chiappori, and Pinquet (2003, Journal of the European Economic Association, 1, 767–820) to include learning about risk and insurance coverage choice over time. We derive testable empirical implications for panel data. We then perform tests using longitudinal data from France during the period 1995–1997. We find evidence of moral hazard among a sub‐group of policyholders with less driving experience (less than 15 years). Policyholders with fewer than five years of experience have a combination of learning about risk and moral hazard, whereas no residual information problem is found for policyholders with more than 15 years of experience. 相似文献
