Transaction cost economics began to take shape around 1970 and has since been established as an essential tool used to illuminate a wide range of problems in economics and other social sciences.

An improvement in the definition of transaction costs to include both the information role and efficiency role requires an integration of the approaches of positive economics and normative economics.
