During the last half-century transaction cost became a prominent consideration in discussions about externalities and ownership arrangements. The author of this essay contributed to this development in the earlier part of this half-century but has since come to doubt the importance of transaction cost and even the roles it is thought to play in these two areas of economic thought.
