Abstract . Developing countries face an inconsistency between the need for more equitable distribution of income and wealth between classes and groups and the goals of an industrial relations system in which the trade unions have a systematic commitment to allied political parties to support them in exchange for some control over economic and social policy, or where unions compete with parties for popular support of certain social and political goals. This is designated as 'political unionism' in contradistinction to 'business unionism' where unions support any party whose overall strategy and objectives are most compatible. The analysis shows that ‘political unionism’ led, in Jamaica and in Trinidad and Tabago, to lags in growth which make industrial relations reform a necessity of an effective program of social change. 相似文献

Growth in U.S. agriculture is linked to the non-farm economy through domestic terms of trade and factor market adjustments. With almost stable input growth, the relatively large contributions from growth in Total Factor Productivity (TFP) are passed on to intermediate and final consumers in the form of declining real prices for primary farm products. The resulting net growth in the real value of farm output (GDP) is relatively low (0.25% per annum). The decomposition of TFP suggests that public agricultural stock of knowledge and infrastructure are robustly associated with TFP growth, while spill-overs from private agricultural and economy wide research and development (R and D) are positive but, relatively small. 相似文献

The purpose of this study was to (a) compare the occupational sex stereotypes of 366 college students with those reported by Shinar in 1975, and (b) examine the relationships between demographic, experiential, and attitudinal variables and these occupational sex stereotypes. The results indicated a significant difference in occupational ratings from Shinar's study, with females' perceptions shifting more than males' perceptions. In addition, subjects' gender, tenure with female managers, and attitudes toward women as managers, were shown to be significant predictors of occuptational ratings. The implications of these findings for both employees and managers are then discussed. 相似文献

We consider a model of an oligopolistic market with heterogeneous firms and products where neither the cost nor the demand functions are common knowledge. Instead, each firm only has some vague ideas about the price strategies adopted by its competitors which is modelled by a fuzzy set. In analogy to the notion of an "equilibrium of actions and beliefs" we define and characterize a generalized Nash-equilibrium and show its existence under general conditions. Furthermore, the impact of the fuzzy information on the equilibrium outcome is analyzed by means of a comparative static analysis within a particular model framework.Received: 28 May 2002, Accepted: 25 December 2002, JEL Classification:

We propose estimation of a stochastic production frontier model within a Bayesian framework to obtain the posterior distribution of single-input-oriented technical efficiency at the firm level. All computations are carried out using Markov chain Monte Carlo methods. The approach is illustrated by applying it to production data obtained from a survey of Ukrainian collective farms. We show that looking at the changes in single-input-oriented technical efficiency in addition to the changes in output-oriented technical efficiency improves the understanding of the dynamics of technical efficiency over the first years of transition in the former Soviet Union. 相似文献

Group decision-making: Head-count versus intensity of preference 总被引:1,自引:0,他引:1
This paper puts forth a framework for reshaping the group decision-making process. The proposed framework extends from the usual one-issue-at-a-time decision-making to one that involves several related issues simultaneously. Weaknesses of the traditional majority voting mechanism are first identified, and then a different voting method that takes each individual voter's sentiment into account is discussed. Specifically, a decision-maker is asked to express his/her intensity of preference for the issues encountered. Three hierarchical structures—benefits, costs, and risks—are developed to evaluate the alternatives. Due to the nature of pairwise comparisons and synthesis, the proposed method is amenable to consensus building and has higher reliability and consistency. It can be used for candidate selection, e.g. governmental election, when a large population is involved. It is also effective for resource allocation and prioritization when a small group or business is concerned. We believe the proposed approach has potential for resolving deficiencies of the conventional voting mechanism, and can be applied to many real-world problems. Its implementation on the Internet is also discussed. 相似文献

In this paper, we consider the problem of estimating a selected set of contrasts between v treatments using a block design consisting of b blocks of size k. Traditionally, the construction of A-optimal block designs for such situations has been carried out assuming a fixed effects model. In this paper, we show that A-optimal designs constructed under a fixed effects model are robust in the sense that these designs have maximal minimal efficiency when considered among all available designs and under all possible mixed effects models.

Prior research has employed a number of methods to test for speculative bubbles in asset prices, including a method based
on the concept of duration dependence. This study explores whether duration dependence tests for speculative bubbles are sensitive
to specification decisions. Our results question the efficacy of using measures of duration dependence to test for speculative
bubbles. In particular, we find that evidence of duration dependence is sensitive to the method of correcting for discrete
observation of continuous duration, the use of value-weighted versus equally weighted portfolios, and the use of monthly versus
weekly runs of abnormal returns. (JEL C41, G12) 相似文献

Collective Intentions and Collective Intentionality 总被引:1,自引:0,他引:1
By L.A. Zaibert 《American journal of economics and sociology》2003,62(1):209-232
A BSTRACT . John Searle believes that collective intentions are crucial to his philosophy, but he is yet to present a coherent account of these entities. No account whatsoever of collective intentions is presented in the book where Searle needs them the most ( The Construction of Social Reality ), or, for that matter, in any other of Searle's major books. The only account, and a defective one at that (so I argue), is found in a short, somewhat obscure article entitled "Collective Intentions and Actions," but in fact what Searle presents there is, at best, an account of collective actions , not of collective intentions. In light of Searle own ground-breaking work in the philosophy of mind, and in particular in light of his far-reaching analyses showing how intentions differ from related mental states, I argue that collective intentions are not consistent with Searle's philosophy of mind. 相似文献

Economists' Opinions of Economists' Work 总被引:3,自引:0,他引:3
A bstract . Economists' credibility has been waning in recent years. Critics usually cite the profession's preoccupation with abstract reasoning and its focus on seemingly irrelevant topics that hold little interest for individuals outside the discipline. While economic science has enormous potential for improving living standards, the profession's adverse reputation is indicative of a discipline seemingly void of any social contribution. This article presents the results of a recently conducted survey of professional economists. The survey was undertaken to ascertain economists' opinions of their own professional work, including the progress of economic research, its usefulness for society, and factors that determine the publication of that research. 相似文献
