Maximum efforts in contests with asymmetric valuations 总被引:1,自引:0,他引:1
Efforts may be reduced when players with different valuations participate in a contest. This paper considers the problem of designing a contest to elicit maximum aggregate effort from players with asymmetric valuations. Optimal designs for different classes of contest technologies are computed and characterized. A value weighted contest is optimal in the concave case. In the unconstrained case, the optimal contest is equivalent to a first price all-pay auction with a reserve price. The optimal design discounts the effort of the high valuation player in order to induce him to compete vigorously. 相似文献

The behavioral approach of decision making has emerged as a diversified solution in the presence of risk and uncertainty. Using the popular cumulative prospect theory as an objective function for portfolio selection, this study implements the classical mean–variance model to compare the portfolio performance of high behavioral stocks with that of stocks with lower behavioral values. Based on a sample of 37 international stocks over the period from October 1998 to November 2017, empirical results from D-vine pair copula GARCH-GEV indicate that the portfolio of high behavioral prospect stocks outperforms the portfolio of stocks with low behavioral scores. This finding may suggest that portfolios with high behavioral values coincide with rational efficiency sets. 相似文献

The paper brings a mechanism design perspective to the study of contests. We consider the problem of selecting a contest success function when the contest designer may also value the prize. We show that any equilibrium outcome that can be achieved by a concave increasing contest success function can be replicated by a linear contest success function. An expected utility maximizing designer should employ a linear homogeneous contest success function. We explicitly derive the optimal contest for a risk-neutral designer and present comparative statics results. Tullock's contest is optimal only when the designer's valuation for the prize is low. 相似文献

This article extends the existing research on logistics customer service‐loyalty relationships to the online logistics supply chain environment by examining potential website determinants of logistics customer service quality. A structural equation analysis of 373 online shopping transactions suggests that perceived quality of all logistics customer service activities (perceived cycle time, in‐stock availability, and customer responsiveness) varies inversely with: (1) perceived ease of use, and (2) content vividness of the website; and positively with product information content. However, only retailer customer responsiveness assessment was found to have any significant influence on consumer intended loyalty behavior in Internet‐enabled supplies chains. 相似文献

Abstract: This paper examines the nature and extent of poverty in Africa. It recognizes that poverty in the region is essentially a rural phenomenon and women are disproportionately affected. The paper argues for an integrated strategy approach to poverty alleviation in Africa which deals with the problem of poverty uprooting at three levels: 1) on those which can be addressed by an effective long term strategy of rapid and broad based economic growth; 2) those which require active population and human resource development policy; 3) and those which need special programs to uproot poverty Résumé: Ce document examine la nature et la portée de la pauvreté en Afrique. Il reconnait que la pauvreté est essentiellement dans la région un phénomène rural et les femmes sont disproportionnellement touchées. Le document plaide en faveur d'une approche de stratégic intégrée de la lutte contre la pauvreté en Afrique qui traite des problèmes d'eradication de la pauvretéà trois niveaux: 1) ceux qu'on peut résoudre par une stratégic efficace à long terme de croissance économique rapide et à base étendue; 2) ceux qui exigent une politique active de developpement de la population et des ressources humaines; 3) ceux qui ont besoin de programmes spéciaux pour extirper la pauvreté. 相似文献

Genuine Wealth Per Capita as a Measure of Sustainability and the Negative Impact of Corruption on Sustainable Growth in Sub‐Sahara Africa 下载免费PDF全文

In this paper, we argue that the answer to the question of whether the impact of corruption on development is homogenous, is no. Our optimism rest on how development may be conceptualised. When equated to a narrow measure in economic‐wise which fundamentally ignores critical issues, then there is a possibility the outlook could be positive. But when conceptualised using a broad‐based approach such as sustainable development, then the outlook could be negative. We assess a panel of 22 economies in Sub‐Sahara Africa with the most recent dataset (1996–2013) from the World Bank and other reputable agencies. Our finding is quite robust. It holds in pooled OLS, Fixed effects and GMM within IV settings; and it also holds for different measures of institutions and different measures of development using growth per capita GDP and genuine wealth per capita, respectively. Taking stock of major policy blue‐prints of selected countries in the region on the fight against corruption, we are able to point out that institutions play important role in insulating citizens against the devastation caused by corruption. Overall, through this comparison, we are able to signal that both incidental and systematic corruption poses a long‐term threat to sustainable development. 相似文献

The Capital Asset Pricing Model (CAPM), and the Fama-French and Carhart models have been widely applied in the developed and most emerging markets; however, there is scant evidence of the viability of the models on the African Frontier Stock Markets (AFSMs). This study examines the viability of the models for a sample that pools securities across nine AFSMs, and whether or not the risk factors of these models command risk premium on the AFSMs. The paper provides evidence of the existence of the size, value and momentum effects on the AFSMs. In addition, the models only partly capture the returns to size and book-to-market sorted portfolios on the AFSMs. Also, the risk factors of these models generally, command marginally significant premium on the AFSMs. Caution should in general be exercised when applying these models on the AFSMs. 相似文献
