Professor of Business Organization at Pompeu Fabra University, Barcelona, and past President of the International Society for New Institutional Economics. My research lies in the conjunction of organization, law and economics. Many of my works focus on the organizational conditions that facilitate impersonal exchange, covering from property titling or business regulation to moral systems. They have been published in, among others, Economic Journal, Harvard Business Review; Journal of Law & Economics; Journal of Law, Economics & Organization; Journal of Economic Behavior & Organization; and Journal of Comparative Economics. My last major work is Institutional Foundations of Impersonal Exchange: Theory and Policy of Contractual Registries, a book published by University of Chicago Press (Amazon site: http://ow.ly/cBMU5), which expands our understanding of how institutions can encourage economic growth by facilitating impersonal exchange. I have also been retained as an expert by international firms and organizations, several national governments and major law firms and consultancies in projects closely related to his research interests. These relate to specific problems of competition policy and business regulation and contracting, as well as broader aspects of titling systems and reform of the business environment.
