William’s research focuses on situations with a poor contractual environment due to asymmetric information or lack of formal enforcement. He studies how repeated interactions or policies can be used to partially overcome the underlying frictions. His work, which has been published in some of the most important journals, is mostly theoretical and carried out at a relatively high level of abstraction, but the insights gathered can be widely applied from the design of transnational institutions, to the design of contracts within an organization, and the regulation of diverse markets by governments.
