法律和信用的博弈分析

Law and Credit: Game Theory Approach

解决信用缺失问题,法律是不可或缺的。然而,单单依赖加大对失信者的法律惩罚并不是抑制失信行为的最佳方法。要建构有效的法律制度以抑制失信行为必须首先从动态、博弈的角度来分析法律的作用机理和效力机制。这就要比较法律规则制定前后经济人(包括执法者)行为的变化(差异)程度,进而分析这些行为变化对交易绩效的影响程度。只有这样,我们才能有效地建构法律制度,从而很好地重建社会信用。

Law is necessarily needed to solve the credit problem. Credit problem, however, can hardly be solved by harder punishment. To solve the credit problem, we should construct the valid law system. And to do this, we should analyze the internal mechanisms of law in game theory approach first of all. That is to say, we should compare the action change (or difference) of economic man before the law system is constructed and after that. What's more, we should analyze the influence of that to the transaction performance. Only in this way, can we construct the valid law framework and thus reconstruct the credit system. 
