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

Theprogram, which Zhejiang Province initiated in the world, has great significance. Through deep investigation in ten cities, the thesis has normatively evaluated current situations, characteristics, advantages and disadvantages of basic life security program for land-expropriated farmers in Zhejiang. Furthermore, it put forward some academic suggestions to further perfect and improve the system.展开更多
