| This paper illustrates the effects of deposit-insurance on assets equilibrium returns steadily in which intermediaries posses more significant status than the other forms of venture investment about the yields on a set of assets. Thence, macroeconomic policy ultimately underwrites the security of banking by deposit-insurance, especially for the fragile banking along with severe hidden hazard in China. The paper develops practical lessons from all this work and distills the evidence into a set of principles of good design, meanwhile, cross-country empirical research and individual-country experience confirm that, for at least being, the financial market principles are more considerable for the effectiveness on a deposit-insurance system.The role of imperfect information in principal-agent model subject to moral hazard is consided. A necessary and sufficient condition for imperfect information obtained by deposit-insurance system to improve on contracts between the bank and depositors based on the payoff alone is derived, and a characterization of the optimal use of such information is given. In addition, the dynamics for investment and consumption under regulatory forbearance leads to need of prudential regulation by deposit- insurance of government. Furthermore, the principles of good design mainly depend on insurance-fund and insurance-premium a dedicated fund of reserves against loss exposures maintains deposit-insurance obligations and efforts to tie premiums to individual-bank risk exposures in a premiums-disintermediation model influence the level of public'welfare.Unlike banking systems in the developed, we could not find effective market disciplines being plenty favorable for deposit-insurance in China, therefore, a set of disciplines of good design as well as the practical targets at present stage become most eventful in the deposit protection scheme. |
