Transaction cost

In economics and related disciplines, a transaction cost is a cost in making any economic trade when participating in a market.^[1] The idea that transactions form the basis of economic thinking was introduced by the institutional economist John R. Commons in 1931, and Oliver E. Williamson's Transaction Cost Economics article, published in 2008,^[2] popularized the concept of transaction costs.^[3] Douglass C. North argues that institutions, understood as the set of rules in a society, are key in the determination of transaction costs. In this sense, institutions that facilitate low transaction costs, boost economic growth.^[4]
