Abstract

The authors anticipate that the primary use of this analysis will be to demonstrate journal price fluctuations by discipline and country of origin to department heads, university and hospital administrators, and others concerned (or who should be concerned) with the costs of health information. The authors expect to repeat this study on an annual basis and would welcome any comments.  相似文献

This article demonstrates a methodology that allows individuals to reach a personal decision on the use of products which carry very small risks to health and life but also offer considerable benefits. A combination of the principles of dominance, extended dominance, and various methods of direct risk-benefit tradeoffs are shown to reduce the number of possible decisions regarding product use to the one optimal for the value structure of a particular individual. An historical examination of toxic-shock syndrome identifies tampons as a product with risks too small to warrant public intervention but too sizeable to be ignored. The methodology described here can be applied for all such products.  相似文献

Objective. The goal of this article is to compare the concern for the natural environment between the citizens of 26 countries that participated in the 2000 International Social Survey Program (ISSP) and to explain the differences. Prior studies (e.g., Dunlap, Gallup, and Gallup, 1993; Brechin, 1999 ) suggest that the increase of environmental concern is a global phenomenon. However, Inglehart (1995) , as well as Diekmann and Franzen (1999) , argue that the level of environmental concern and knowledge is highly correlated with GNP per capita. Method. The article analyzes new evidence obtained from the ISSP 2000 and compares it to the prior findings based on the ISSP 1993. Results. It is shown that citizens in wealthier nations express greater concern for the global condition of the environment than those in poorer countries. Conclusion. The new analysis of the ISSP 2000 confirms our original notion that support for global environmental protection is strongly correlated with wealth. However, the increase in real GDP between 1993 and 2000 did not lead to a further increase in environmental concern.  相似文献

Do polls simply measure intended voter behavior or can they affect it and, thus, change election outcomes? Do candidate ballot positions or the results of previous elections affect voter behavior? We conduct several series of experimental, three-candidate elections and use the data to provide answers to these questions. In these elections, we pay subjects conditionally on election outcomes to create electorates with publicly known preferences. A majority (but less than two-thirds) of the voters are split in their preferences between two similar candidates, while a minority (but plurality) favor a third, dissimilar candidate. If all voters voted sincerely, the third candidate — a Condorcet loser — would win the elections. We find that pre-election polls significantly reduce the frequency with which the Condorcet loser wins. Further, the winning candidate is usually the majority candidate who is listed first on the poll and election ballots. The evidence also shows that a shared history enables majority voters to coordinate on one of their favored candidates in sequences of identical elections. With polls, majority-preferred candidates often alternate as election winners.  相似文献

The Economic Partnership Agreements between the African, Caribbean and Pacific countries and the European Union should serve as an opportunity to accelerate ACP global and regional trade integration and as an important tool for development and the eradication of poverty. There are, however, a number of preconditions. This article argues that institutional quality plays a key role in successful trade liberalisation. In fact, only countries with high‐quality institutions, partly in the form of good government regulation, are likely to benefit from trade. Unfortunately, the vast majority of African countries have excessive regulation that hinders them from taking advantage of trade. The necessary reforms to resolve this problem pose significant challenges, implying major risks for these countries in the EPA process.  相似文献
