The underlying causes of ethnic mobilisation have been addressed by theories of cultural pluralism, ethnic competition, differential economic incorporation and modernisation. Up to now, no quantitative cross‐national study has tested all these perspectives simultaneously. The results of this study provide support for some aspects of the different theories, with the exception of the theory of differential economic incorporation. The results of the synthetic model stress the importance of examining multiple perspectives in order to avoid only partially correct representations of the historical reasons behind ethnic conflict in black Africa. 相似文献

This paper develops the key finding of Ozanne, Hogan and Colman (2001) that risk aversion among farmers ameliorates the moral hazard problem in relation to agrienvironmental policy compliance. It is shown that risk averse farmers who face uncertainty in their production income are more likely to comply with such a policy as a means of risk management. In addition, it is shown that a principal who has control over both the level of monitoring and the size of penalty, if detected, can reduce non‐compliance by adjustments to these instruments which increase the variance of farmers' income but leave the expected penalty unchanged. It is concluded that risk management by both principals and agents has the potential to diminish the moral hazard problem, especially given proposed developments in agri‐environmental policy in the European Union. 相似文献

It seems that everybody wants to know which companies are the most successful. To help throw light on the issue, and to do so more reliably than the plethora of league tables and charts produced by most business magazines, the London Business School have teamed up with The Economist to compile an assessment of the top performers of the 1980's. 相似文献

This article investigates the impact of a protein premiums and discounts system on the income stream from growing wheat. Based on a biological relationship between protein and yield in uncertain seasonal conditions, it shows that such a system reduces the expected level and variability of wheat income. It is subsequently argued, using a numerical analysis, that protein payments affect both the attraction to wheat growers of forward contracts and the value of land used for wheat. The nature of both of these impacts is related to the level of seasonal variability affecting the land. Consequently, wheat growers in the more unreliable regions of the wheatbelt may have been particularly disadvantaged by the system. 相似文献

We investigate bank stocks'sensitivity to changes in interest rates and the factors affecting this sensitivity. We focus on whether the exposure of commercial banks to interest rate risk is conditioned on certain balance sheet and income statement ratios. We find a significantly negative relation between bank stock returns and changes in interest rates over the period 1991–1996. We also find that bank characteristics measured from basic financial statement information explain bank stocks'sensitivity to interest rate changes. These results suggest that bank managers, analysts, and regulators can use this information to assess the relative risk exposure of banks. 相似文献

Embedded within firms are unique stores of intangible human assets that likely influence the way firms compete. We argue that the human and social capital of a firm, particularly at the upper echelon and board of director (BOD) levels, contribute to the firm's awareness of the competitive environment and its motivation and ability to undertake numerous, complex, and forceful competitive actions. We also suggest that the firm's executive compensation systems moderate the effects of these intangible human assets on firm competitive behavior. By examining how human capital, intra-firm social capital, and executive compensation influence firm competitive behavior, we advance a strategic HRM perspective of firm competitive behavior and outline several implications for future research. 相似文献

After a long period of awarding spectrum licenses inefficiently, changes in the budget and budgetary process coupled with increases in the value of the spectrum for non-broadcast use led Congress to allow the Federal Communications Commission to award licenses through competitive bidding. Contrary to the perceived view of government bureaucracies as excessively cautious, the FCC used the newfound authority to adopt a novel approach to auction design—simultaneous multiple round auctions. The innovative auction design would not have been adopted without the successful collaboration between government economists and academic economists, who helped to formulate and refine the design so that decision makers at the FCC could be convinced that the novel technique was both superior and practical. The FCCs implementation of competitive bidding was not only rapid as mandated by Congress, but also much less costly than outside alternatives and allowed the integration of spectrum policy decisions and auction design. Experience from several auctions has led to a number of open questions and refinements. The FCC is trying to replicate the success with the original auction design by facilitating dialog between the agency and outside auction experts in order to address these issues. 相似文献

This research examines the high level of change in supply organizations of large North American companies using data collected from 51 large North American supply organizations in 1987, 1995 and 2003. Analysis is supplemented by an additional 55 companies for which data were collected in 1995 and 2003. The availability of longitudinal data from individual companies over a 16-year period provided a unique opportunity to trace changes made to each company's supply organizational structure and their roles and responsibilities. Findings suggest that the respondents made major changes in supply organizational structure, supply chain responsibilities, use of purchasing teams, supply involvement in major corporate activities (MCA) and CPO reporting line, title and background. 相似文献

This note corrects a slip in Fraser's (J. Econ. Theory 90 (2000) 204-221) treatment of the necessary condition for partial separation of efficiency from distribution in providing a club good. His corrected Theorem 1 shows that many families of utility function can generate partial (and total) separation, thereby considerably extending the scope of his analysis. 相似文献
