The equilibrium levels of self-protection and insurance coverage under the non- cooperative condition are compared with socially optimal solutions, and the associated coordination mechanisms are proposed. The results show that self-protection investment increases in response to an increase in potential loss when the interdependent risk is small; the interdependent risk of security investments often induce firms to underinvest in security relative to the socially efficient level by ignoring marginal external costs or benefits conferred on others. A subsidy on self-protection investment from the government can help coordinate a firm＇s risk management decision and, thereby, improve individual security level and overall social welfare.展开更多

Background: Stigma and discrimination continue to complicate effective World AIDS Day activities in China. Including foreign students in World AIDS Day campaigns broadens the potential Chinese audience as well as making the government's AIDS policiesmore transparent. Methods: In order to broaden the potential audience, relevant media (television, radio, newspaper) were notified of the 2003 Nanjing World AIDS Day Exhibition. The exhibition represented a unique collaboration between Nanjing University and the Chinese National Center for STD and Leprosy Control, depending on foreign and Chinese students at several levels. In addition, close contacts at the Jiangsu Provincial Health Bureau helped to coordinate local experts and distribution of condoms. Results: This multi-disciplinary cooperative exhibition was successfully completed. Several major media sources covered the event. Conclusions: The success of this campaign suggests that other urban cities with significant foreign student populations could benefit from including foreign and Chinese students in future World AIDS Day campaign activities.展开更多
