This paper studies the trading behavior of an irrational insider and its influence on the market equilibrium in the presence of market *** find that the market with only one insider with private information is almost close to a strong efficient market,under the condition of market *** the equilibrium,the probability of the insider being caught trading with private information is zero,which shows that the reasonable behavior of the regulator is to essentially give up *** the market efficiency and the irrational trader’s trading intensity all greatly improve because of the existence of the market regulation.

This paper is concerned with a linear-quadratic stochastic Stackelberg differential game, where players have asymmetric roles, with one leader and one follower in the context of two-person game. It is required that the information available to the follower is a sub-σ-algebra of the one of the leader. By maximum principle and optimal filtering, a feedback Stackelberg equilibrium of the game is given. A special example is used to elaborate the result.

In this paper, the issue of quality evaluation level decision problem in outsourcing is studied under different information backgrounds. Based on the quality contracting optimization models of Stanley and others, a principal agent model concerned with quality prevention level and evaluation level is set up with regards to buyer as principal and supplier as agent. In the models, quality prevention level is a variable decided by the supplier, quality evaluation level and transfer payment are variables decided by the buyer. We focus on the study of quality evaluation level and transfer payment decision in outsourcing under asymmetric information. Maximal principle is used to get the solution to quality evaluation level when supplier quality prevention level information is hidden. At last simulation calculation is performed concerned with tractor production outsourcing business of an agricultural machine company. Simulation results under different information backgrounds are analyzed and compared.

The quantity discount contracts are investigated for a one-supplier-one-retailer supply chain with asymmetric information when the retailer's cost is disrupted. While the retailer's cost structure is asymmetric information, two all-unit quantity discount contract models, fixed expected-profit percentage discount(FEPD) and fixed wholesale-pricing percentage discount(FWPD) under asymmetric information are proposed in a regular scenario. When the retailer's cost distribution fluctuates due to disruptions, the optimal emergency strategies of supply chains are obtained under asymmetric information. Using numerical methods, the impact of cost disruptions on decisions about the regular wholesale price, discount wholesale price, order quantity and expected profits of the retailer, the supplier as well as the total system are analyzed. It is found that the FEPD policy is more robust and adaptable than the FWPD policy in disruption circumstances.

The challenge for supply chain management is to create appropriate supply chain contracts so as to optimize the system performance. To examine the role of asymmetric information in a two-echelon supply chain system and derive supply chain contracts to deal with existing asymmetric information, a two level supply chain model including one Supplier and one retailer under the demand of price elasticity is developed. By using the principalagent principle and the optimal control theory, three types of supply chain contract, i. e. , a wholesale pricing contract, a two-parameter linear and a two-parameter nonlinear contracts are obtained. In these contracts, the Supplier has asymmetric information about the retailer cost structure. Simulation results show that the two-parameter contracts are more effective strategies to achieve supply chain coordination.

In contemporary society, the problem of information asymmetry in talent markets has been becoming more prominent. On one hand, the company and candidates fight against each other based on the information available, so both of them could make fraud that will make the market level lower and lower. On the other hand, former scholars have studied from enterprises＇ perspective and put forward methods to solve it based on the aspect of improving the technology and standard mechanism, which could not solve the problem of information asymmetry thoroughly. Consequently, this research put up with the idea that the market can reduce information asymmetry through the establishing personnel information database and related platforms, which has a great practical significance on realizing the optimal allocation of the market and saving cost. At the same time, this study discussed the problems of information asymmetry fundamentally, which was of great importance to enrich the related theory research. Specific models were constructed through two perspectives from the enterprise and the candidates. And then two models would be eventually integrated into a large system. Finally, this research put all related information into a system, which was beneficial to the optimal allocation of human resources with constraints of the market environment.
