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

This paper explores the impact of copyrights on firm value and on the demand for firm output. Using panel data on franchise value and ticket sales from the National Football League over the 1991–2000 period, we analyze the effect of copyrights (in this case, team logos) using several parametric estimators, the Arellano and Bond [1991. Some tests of specification for panel data: Monte Carlo evidence and an application to employment equations. Review of Economic Studies 58, 277–297] dynamic panel data estimator, and a semi-non-parametric method based on difference-in-differences propensity score matching. We find a negative effect of logo changes on franchise value that is robust across multiple specifications. In addition, logo changes also appear to have a moderate positive, albeit not particularly robust, impact on ticket sales.  相似文献

The linkage between development and health is clearly spelt out in the definition of primary health care by the World Health Organisation. There is a widespread and growing disillusionment with the traditional Western approach to health care which fails to meet the real demands of the Third World situation.

This paper looks briefly at conditions in the developing world and the strategy proposed by the W H O to attempt to meet the objective of health for all by the year 2000 and refers to the South African situation.  相似文献

Summary In this article it is shown that Keynes concept of uncertainty is not identical with that of Knight, as is often argued. The identification of Keynesian with Knightian uncertainty has contributed to the neglect of an aspect of Keynesian uncertainty that is important in understanding the functioning of a monetary economy. Therefore, it is concluded that monetary theory can benefit from the development of an analytical apparatus that incorporates all aspects of Keynesian uncertainty.I am indebted to Mr. J. de Haan, Professor J.A. Kregel, Professor S.K. Kuipers, Professor J. Pen, Dr. J. Snippe and Mr. A. van Witteloostuijn for their comments on an earlier version of this paper. It goes without saying that they cannot be blamed for any remaining errors.  相似文献

This research was designed to see whether a reconceptualization of social distance (as measured by social class variables) between shoppers and stores would provide a basis for understanding store avoidance behavior. A survey of shoppers classified into two distinct social classes investigated their images, including social class images, of two stores that had been selected as representatives of upscale and downscale retailers. A new measure of social distance was proposed and evaluated. Controlling for other functional aspects of store image such as price and personnel, the social distance measure was found to be influential in discriminating shopping frequency groups for the two stores, providing evidence that people tend to avoid stores that are perceived as being socially distant from themselves.  相似文献

The product management form of organization has been around for quite a while; yet little empirical research has been done on product managers. This article reports a study of product managers and some organizational behavior factors which contribute to their job satisfaction and job performance. These factors include centralization of decision making, job structure, job scope, role ambiguity, and role conflict. Finally, several suggestions are made for creating an environment more conductive to having product managers who are satisfied with their jobs.  相似文献

改革开放初期,由于缺乏建设资金,我国用各种优惠政策吸引外资以加快经济建设,取得了显著成效.但近些年来,在利用外资促进经济发展的过程中,外资流入与国内储蓄"双溢出"现象日益突出,这似乎与传统的利用外资"双缺口"理论相悖,但实际情况并非如此.本文分析论述了我国引进外资从"双缺口"到"双溢出"的变化过程及原因,并论述了在"双溢出"情况下应该如何引进外资.  相似文献

Question order effects in taste testing of beverages   总被引:1,自引:0,他引:1  
The effect of order position has been demonstrated in marketing research, sometimes compromising survey results. This paper studies the influence of order position in product taste trials of carbonated beverages using a sequential monadic design. The authors measure attitude ratings across product trials rather than across products to examine the effect of order position on preference ratings.  相似文献

The efficiency of a research design may be measured in terms of the degree to which knowledge is enhanced within given resource constraints. Thus, two different types of research design, even though they contain the same number of expected observations, may differ considerably in the amount of information provided. An example is the number N of 32 observations obtained with an analysis of variance witheither 2 factors, 2 levels per factor and a replication of 8or 4 factors, 4 levels per factor and a replication of 2. We analyze and compare the relative efficiencies of regression and variance analysis models and their implications to research strategy development. Three major considerations are evaluated: (1) short versus long time horizon (interval until effects of a decision are realized), (2) small versus large cost of erroneous rejection of the Null Hypothesis and (3) gross versus refined stage of development of the research study. A set of general guidelines towards improved designs is developed.  相似文献
