According to static game model, it re-vealed that the reason for low compliance rate of ＂company ＋ farmer＂ model was the existence of market risk, namely, the fluctuation of market price, and the stable market price in contracts was actualy a kind of interval, instead of a specific value. Furthermore, the effect of default penalty, market transaction cost and time prefer-ence cost on the stability of contract was studied. The results showed that default penalty, market transaction cost and time preference cost had positive influence on the price interval range of a contract.展开更多

Firstly, the paper describes the problem of moral hazard in dynamic alliance and introduces the Tirole Model of moral hazard prevention. Then, by introducing a third-party system into dynamic alliance, a model of incomplete information dynamic game theory is formulated in the principal-agent framework. The model shows the dynamic consistency between a member＇s income and the dynamic alliance＇s profit, and that moral hazard can be prevented by an allocation policy With both characteristics of incentive measures and supervision, which is designed by a third-party system. Finally, the composition of the third-party system is discussed.展开更多

But as the existence of information asymmetry between buyer and seller, the moral hazard problem is the key obstacle that impedes the benefits of related shareholders and reduces the efficiency of total market. It is crucial to design a control mechanism to avoid the negative impact of moral hazard. This paper studies the principal and agent relationship between buyer and seller in C2C e-market;because of the influence of information asymmetry, many customers suffered from being cheated by sellers with defective products in practice. These frequent cases will deteriorate long term relationship between sellers and buyers. Here we focus on the analysis of the causes of moral risks and the effect of reputation on oral risk with repeated game theory. The purpose of this paper is to help both firms and customers effectively avoid morality risk and realize a win-win situation.展开更多

We set up the supplier and buyer＇s expected profits function model, in which the supplier makes production process investment-level decision and decides on the product quality prevention level, whereas the buyer makes quality evaluation decision and decides on the product quality inspection level. The supplier with a moral hazard of reducing investment level may lack investment in the production process; thus, the buyer will pay the information rent to incentivize the supplier to improve the investment level. The buyer creates the moral hazard of exaggerating the product quality defective rate, who may overinvest in the inspection process. We use the optimal condition to solve supplier＇s first-best investment level, product quality prevention level, and buyer＇s first-best quality inspection level, internal penalty, and apportionment ratio of external failure cost. We also conduct a simulation test that shows the following： When the supplier improves its investment level, its product quality prevention level will increase, and the buyer＇s quality inspection level will decrease. With the improvement in the buyer＇s product quality inspection level, its internal penalty will increase, and the supplier＇s external failure cost will also increase while its expected profits will decrease. Hence, the buyer will design an incentive contract, the expected profits of which will increase, and the whole supply chain＇s joint expected profits function may become an inverse U shape. Finally, we develop a simulation example and propose suggestions for quality control strategy and contract design in the supply chain under the conditions of asymmetric information.展开更多

The two parties, the principal and the agent, generally have different levels of production efficiency, relative importance factor and are risk-averse or risk-neutral. Using this model, we formally prove that the optimal contract maximizes the output net of the disutility of both the parties and carry out some simulations exercise under two special cases which help explain the double-sided moral hazard issues. By focusing on production efficiency, relative importance factor and risk attitude respectively, this paper analyzes the properties of optimal contracts under three cases.展开更多
