Easing renegotiation rules in public procurement: Evidence from a policy reform
利用捷克共和国实施欧盟政策带来的自然实验，研究了放宽重新谈判规则对公共采购结果的影响，发现政策降低了中标价但未改变最终价格，且项目质量未下降。
Public procurement contracts require frequent renegotiation. Exploiting a natural experiment induced by the implementation of an EU policy in the Czech Republic, we examine the effect of easing renegotiation rules on the outcomes of public procurement. We document that the policy decreased winning bids but did not change the final price, as post-award renegotiations offset the initial bid reductions. We find no evidence of a decline in the quality of the delivered procurement projects. We rationalize our findings using a stylized theoretical model.
