Illuminating the Development of Precontractual Liability: A Comparative Law and Economics Analysis

By using the tools of comparative law & economics, this article aims to shed a light on the development of precontractual liability. Precontractual liability sensu stricto is about the question to what extent one can be held liable for cost incurred by the other party preliminary to, or during precontractual negotiations, when negotiations fail. Comparative legal analysis has observed that the requirements for establishing a successful claim for precontractual liability are very similar at common law and at civil law despite the very different starting positions from which each legal system’s rules have developed. By finding correspondence between what comparative law has found and what is expected under an efficient legal system, this study provides empirical evidence for the efficiency hypothesis of law.
