Dual anchors in the shadow of the future: how renewal expectations and relational history govern behavior in public contracts

Deanna Malatesta, Faisal Saeed Cheema

Abstract

Abstract This study extends relational contract theory by showing how behavioral reference points can be established through policy. We theorize that contracts are governed by dual anchors: backward-looking relational history and forward-looking renewal expectations. Analyzing 430 public legal service contracts using Heckman selection models, we find relational history increases prices in amendments, revealing its “dark side.” A nonbinding renewal clause, however, significantly attenuates this effect, reducing price increase probability by up to 37 percentage points. These findings resolve the puzzle that renewal clauses, though present in fewer than half of contracts, disproportionately appear in amended agreements. The clause does not guarantee renewal but alters behavioral logic, transforming the supplier’s reference point from backward-looking entitlement to forward-looking relationship preservation. Our findings provide microfoundations for how institutions structure relational dynamics and demonstrate how procurement design can shape expectations to improve outcomes.

未来之影中的双重锚点:续约预期与关系历史如何治理公共合同中的行为

Deanna Malatesta, Faisal Saeed Cheema

摘要

摘要:本研究拓展了关系合同理论,表明行为参照点可以通过政策得以确立。我们提出,合同受双重锚点治理:向后看的关系历史与向前看的续约预期。我们使用Heckman选择模型分析430份公共法律服务合同,发现关系历史会提高合同修订中的价格,揭示其“阴暗面”。然而,一项不具约束力的续约条款显著削弱了这一效应,使价格上涨概率最多降低37个百分点。这些发现解开了如下谜题:续约条款尽管出现在不到一半的合同中,却不成比例地出现在经修订的协议中。该条款并不保证续约,但改变了行为逻辑,将供应商的参照点从向后看的应得权利转变为向前看的关系维护。我们的发现为制度如何塑造关系动态提供了微观基础,并表明采购设计可以塑造预期以改善结果。
