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
This article examines what happens to those who live in and around monuments as a result of World Heritage designation. Using the examples of Borobudur and Prambanan in Indonesia as study sites, it is argued that the values that local people attach to heritage are often different from, although not necessarily less important than, the values ascribed by international agencies, government officials, tourism developers and others. However, their perspectives are often not adequately represented or respected by other participants in the planning and management of sites, to the detriment of both the plans and the people. The tendency to adopt top-down, rational comprehensive planning procedures has resulted in the disenfranchisement of local people, giving greater prominence to expressions of national, 'official' culture and nationalism at the expense of local culture. It has tended to freeze sites and displace human activities, effectively excluding local people from their own heritage. 相似文献
