Coase and transaction costs reconsidered

What is Coase’s understanding of transaction costs in economic theory and history? Our argument in this paper is twofold, one theoretical and the other empirical. First, Coase regarded positive transaction costs as the beginning, not the end, of any analysis of market processes. From a Coasean perspective, positive transaction costs represent a profit opportunity for entrepreneurs to erode such transaction costs, namely by creating gains from trade through institutional innovation. We demonstrate the practical relevance of entrepreneurship for reducing transaction costs by revisiting the case of the lightship at the Nore, an entrepreneurial venture which had arisen to erode the transaction costs associated with regulation by Trinity House, the main lighthouse authority of England and Wales. By intervening into the entrepreneurial market process, Trinity House would pave the way for the nationalization of the entire English and Welsh lighthouse system. By connecting our theoretical contribution with an empirical application, we wish to illustrate that Coase’s theoretical understanding of transaction costs is inherently linked to an empirical analysis of market processes.
