The paper develops a framework for analyzing distribution methods of Chinese listed companies with dual-class stocks, compares the influences of different distribution methods upon the value of tradable shares and non-tradable shares, and studies the equity cost effect of repurchases.

To support the reform of state-owned enterprises (SOEs), asset management companies (AMCs) have implemented debt-equity swaps in some SOEs and signed repurchase agreements with them.

But this way of "buy-back write-off " is restricted by fund situation and has loopholes in system,and it is also likely for the company to influence its share price by using inside information.

it designs a simple and practical buy-back contract to coordinate hybrid distribution supply chain system with short life-cycle products.

In this paper, we studied the pay-off relations of bond exchanging market, bond repo market and other risky markets, under some conditions, we obtained optimal model for bond exchanging market, bond repo market and other risky markets.

In contrast with repo, the interbank funding still performed inactively.

Supplier′s optimal buy back decision under asymmetric information in a two-stage supply chain;

The buy back policy aiming at solving the inefficient problems aroused by asymmetric information and incompatible incentives in the supply chain has been applied abroad in practice.

Based on the issue of newsvendor problem,this paper discusses the buyback incentive of the surplus value of overstock in the end of sale season when the information is asymmetry,proposes the conditions of the incentive contract menu to screen the information,and proves the effectiveness of information screening strategy which is based on buyback contract.

A mathematical model is developed to analyze buyback incentive policy with car update time,maintaining level,investment cost,and secondhand market effect considered.

Supply chain coordination using buy back policies;
