The Coase theorem: coherent, logical, and not disproved

Abstract

Abstract:There exists a long line of challengers to the ‘Coase Theorem’. All of these rest on fundamental misconceptions of property rights, transaction costs, and their interaction. Here I examine two attacks that have gone unchallenged: one by Halpin, the other by Usher. I argue that both, in failing to either use or understand an adequate definition of transaction costs, fail to deliver a fatal blow to Coase's famous idea.
