Discrete network design problem with budget constraint;

In order to show that the decision-making characteristics of loss constraint models are different from the ones of budget constraint models, the solutions between those two .

Then,the mode of local government with independent e-conomic benefit is discussed,with hard budget constraint and inter-region competition added to highlight the ef-fect on the economic efficiency.

When lacking in relative information, enterprises are unable to enforce hard budget constraints and, under the soft budget constraints, the administrative personnel have faint motivation to set up and carry out regulations, which in turn results in some decision-makers resisting and even destroying the regulations with the desire of the rent seek of power.

In a sequential English auction,a seller with two objects faces a group of bidders who are subject to different budget constraints.

In this paper, we analyze the reasons of credit risk by the theory of Soft Budget Constraints.

It can be helpful for the local government to curb their predatory hand on market,and harden the traditional soft budget constraints.

Using a dynamic game model of incomplete information,this paper discusses the relations among financial crisis,regulator s soft budget constraints and banker s moral hazard.
