Nash equilibria with identical supports are compared for bimatrix games that are different with respect to the risk aversion of player 2. For equilibria in 2× 2-bimatrix games and for equilibria with efficient supports in coordination games it is established for which cases increased risk aversion of player 2 benefits or hurts player 2.  相似文献

This paper explores the political significance of Asian American campaign finance activity in municipal elections. We examined both the donation patterns of Asian contributors and the fundraising coalitions assembled by Asian candidates. From the contributor perspective, we found that Asians contributed in roughly proportional levels to their population as a whole, and were willing to contribute not only to coethnics but also to Asian candidates of other ethnicities and to non-Asians. As for Asian candidates, we found that they relied heavily on Asian contributors for campaign funds, especially coethnics. Asian candidates’ ability to draw on ethnic networks for campaign funds is an important political resource that enhances their ability to mount competitive campaigns. However, the value of these networks is limited by candidates’ inability or unwillingness to form panethnic fundraising coalitions.  相似文献

Objectives . Property rights are central to debates about natural resource policy. Governments traditionally have been seen as the appropriate custodians of natural resources for their citizens. More recently, many argue the privatization of property rights will ensure that users have incentives to manage their resources well. Common property, to the extent it is discussed at all, is seen as leading to the tragedy of the commons. We evaluate these claims by assessing property rights and forest conditions in two private and three communal forests in Guatemala. Methods . Data on biological and social phenomena from five forests (151 plots) and their associated communities were collected using the International Forestry Resources and Institutions Research Program protocols. Ordinary least squares regression was used to analyze four models. We examined t -scores for differences in coefficients for the different models. Results . The models demonstrate that de jure property rights are not a powerful predictor of variations among the sampled forests. Conclusions . We argue that de facto institutions and their enforcement are much more important than de jure property rights to forest management. Communities holding a forest in common can, under certain circumstances, create institutions to manage their resources as successfully as—or more successfully than—private owners.  相似文献

In order to provide benefits to society, human medical trials must place subjects at risk of harm. This activity is thought to be justified in part by the consent of the subjects involved. But, studies have shown that most such consents are based on a therapeutic misconception (TM); the false belief of subjects that their researchers will act as their personal physicians (seeking their benefit and protecting them from harm), rather than placing them at risk of harm for the good of others. Toleration by researchers of the TM in their subjects is a form of "informational manipulation" that renders consent procedures disrespectful to subject autonomy. Consent obtained from subjects who labor under a TM is neither voluntary nor informed; as long as they have not been disabused of the TM, the action they take in enrolling in a trial is not the one they intend nor is it autonomously chosen. Changes in consent procedures should be adopted to ensure that all subjects are aware inter alia that (a) the health interests of future patients (as well as the researchers' and their sponsors' financial interests) may be more important to researchers than the interest of a subject in his or her health, and (b) normal subjects neither understand nor believe this when told. Close attention to the response of prospective subjects to this information should allow for the exclusion of all but the truly altruistic. However, the result of conscientious implementation of such policies would likely be that human medical research could no longer be conducted on more than a minimal level.  相似文献

Changing Chinese family patterns caused by immigration have contributed to the breakdown of traditional community and familial control in Chinese-American families. As a result, the Chinese-American elderly are faced with unique psychosocial problems that workers must consider when providing services to this population.  相似文献

Objective. Studies of the election of women to public office have been increasingly encouraging about their prospects of female candidates. The purpose of this study is to examine the extent to which gender roles continue to influence the election of women to local office and the pool of candidates for higher office. Methods. Utilizing data on the gender of officials, the nature of the office, and constituency demographics from county elections in eight Southern states, we construct logit models of the election of women. Results. Women hold few local offices involved in fighting crime or of an executive nature. On the other hand, women routinely win election to process‐oriented offices with less discretion. Our analysis of constituency demographics reinforces our conclusions. Women win election in areas where the public office is relatively undesirable compared to other opportunities and the ratio of high‐quality male to high‐quality female candidates is relatively low. Conclusions. Although the frequent election of women to county office provides an expanded pool of female candidates for higher offices, it seems unlikely that women will find it as easy to move up the electoral ladder into the more competitive arena of high‐profile statewide and federal leadership offices.  相似文献
