Williams Fuchs is a professor of finance in the McCombs School of Business at The University of Texas at Austin. He directs the finance Ph.D. program. He was previously an assistant professor at the University of Chicago and at the University of California, Berkeley.

His 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.

Fuchs' research has been supported by some of the most prestigious grants, including two National Science Foundation grants and a Consolidator Grant from the European Research Council.

He received his Ph.D. from the Economics Analysis and Policy Group at the Stanford Graduate School of Business in 2005.
