This paper examines the impact of renegotiations on contract renewals. Using an original dataset of procurement contracts in the French car park sector, we show that there exists an optimal level of renegotiations that positively affects the probability of renewing a contract with the same partner. This result holds only when public authorities have discretionary power during the awarding procedure. Such findings suggest that what is usually interpreted as a sign of weakness – frequent renegotiations – might well be good news that indicates that the contracting parties can make contracts adaptable over time.

公共合同的重新谈判和更新

本文考察了重新谈判对合同续签的影响。使用法国停车场行业采购合同的原始数据集，我们表明存在最佳重新谈判水平，这对与同一合作伙伴续签合同的可能性产生积极影响。只有当公共当局在授予程序中拥有自由裁量权时，这一结果才成立。这些调查结果表明，通常被解释为软弱的迹象——频繁的重新谈判——很可能是个好消息，表明缔约方可以使合同随着时间的推移而具有适应性。
