In this paper, we investigate the optimal form of reinsurance from the perspective of an insurer when he decides to cede part of the loss to two reinsurers, where the first reinsurer calculates the premium by expected value principle while the premium principle adopted by the second reinsurer satisfies three axioms: distribution invariance, risk loading, and preserving stop-loss order. In order to exclude the moral hazard, a typical reinsurance treaty assumes that both the insurer and reinsurers are obligated to pay more for the larger loss. Under the criterion of minimizing value at risk (VaR) or conditional value at risk (CVaR) of the insurer's total risk exposure, we show that an optimal reinsurance policy is to cede two adjacent layers, where the upper layer is distributed to the first reinsurer. To further illustrate the applicability of our results, we derive explicitly the optimal layer reinsurance by assuming a generalized Wang's premium principle to the second reinsurer. 相似文献

本文从逻辑和历史相结合的角度,论述了农业科技发展作为一个过程所具有的三个方面的规律性,即：①生活资料需求、生产资料需求、生态环境需求和社会文化需求等多样化的社会需求是推动农业科技发展的主要动力;②清除或缓解生产要素配置中的“瓶颈”制约,是农业科技发展的突破口;③提高由社会生产力和自然生产力构成的农业生产力的整体水平,是它业科技发展的落脚点。 相似文献

This paper examines the impact of insider trading on completed and canceled private equity offerings. We find that insider trading has no impact on firms’ decisions to complete or cancel offerings, but it has a positive impact on the long‐run stock performance of the issuing firms. Firms complete the undervalued offerings and cancel the offerings when they no longer perceive their shares are undervalued. Firms with weaker operating performance are more likely to complete private placements because they regard private offering as the last resort for raising equity capital. Firms that complete private placements have significantly better long‐term stock performance than firms that cancel private placements. 相似文献

In this paper, the Japanese methods of regional developments with media contents are being analyzed. Taking Hokkaido or Sakaimitato as examples, the effects on the tourism with media contents will be explained in detail. Then, as a new idea, the concept of local consumed intellectual property will be proposed. Finally, the measures of solution of copyright which is difficult to deal with when using media contents would be discussed by including legislations. 相似文献

This paper develops a model for assessing options in joint ventures. The model is used specifically to examine the option to acquire or divest a joint venture, both in the case where the acquisition/divestiture price is specified ex ante in the initial contract and in the case where the price is to be negotiated ex post. The results derived from the model show how the value of the option and each partner's pay‐off from the venture vary with the structure of the option and how the presence of the option may affect the structuring of the joint venture. The main theoretical insights are stated in 12 potentially testable propositions, and possible ways to operationalize some of the propositions for empirical testing are also explored.

We studied the allocative efficiency of a social security system with earning tests focusing on the leisure–work choices of older men. Given empirical findings that health status and social security benefits are the most important determinants of such choices, we incorporated risks with respect to health status into an overlapping–generations model, and analysed how allocative efficiency was changed by the introduction of social security systems. It was found that the effects of a social security system can be broken down into particular categories and that a social security system improves efficiency when the pension system is small.

En 2010, tras la huelga en Honda, hubo protestas laborales en toda China. Los gobiernos de Shenzhen y Guangdong reaccionaron desempolvando los proyectos de Decreto sobre consulta colectiva y de Normativa sobre gestión democrática de las empresas, retirados con anterioridad. Pero tras la oposición frontal de cámaras de comercio y organismos gubernamentales extranjeros, hongkoneses y taiwaneses, volvieron a retirarse. Mediante entrevistas, los autores revelan los medios de influencia en la legislación laboral china de estos actores, cuyas actitudes dependen de la posición de las empresas representadas en las cadenas mundiales de producción y del modelo de relaciones laborales de su país o territorio de origen. 相似文献
