Trust is a central concept in the regulation of public services. Two different models of trust can be distinguished, involving the creation of either substantive credible commitments or institutions to promote more collaborative relations. In this article, the differing implications of these two models are assessed through an examination of failed United Kingdom examples of the use of contracts for the provision of public services: the procurement of passenger rail services by means of franchises and the contracting out of a major part of the probation services. It is suggested that their problems can largely be explained through a failure to recognize the second model of trust in contractual provision, and possible institutional alternatives that might do so more fully are explored.

公共服务、承诺和信任的合同提供

信任是公共服务监管的核心概念。可以区分两种不同的信任模式，包括创建实质性的可信承诺或机构以促进更多的合作关系。在本文中，通过审查英国使用合同提供公共服务的失败例子来评估这两种模式的不同含义：通过特许经营方式采购客运铁路服务和将主要缓刑服务的一部分。有人认为，他们的问题在很大程度上可以通过未能认识到合同条款中的第二种信任模型来解释，并且探索了可能更充分地这样做的制度替代方案。
