The legacy of R. Coase (1910–2013): toward a theory of institutional 'moving equilibrium'?

Over almost a century, Ronald Coase’s works have largely differed in their contents. Under the general umbrella of the “law and economics” field, Coase’s scientific production has indeed covered a large variety of topics and policy issues. However, Coase’s analyses reveal a common framework, if not a structured methodology. We highlight five key ingredients of the “Coasean methodology” and apply them to revisit Coase’s main contributions. The resulting picture reveals a comprehensive theory of institutional “moving equilibrium”, where the institutional design of socioeconomic transactions is affected by the dimension of transaction costs.
