Talia Gillis studies the law and economics of consumer markets. She is interested in household financial behavior and how consumer welfare is shaped by technological and legal changes. In her research she has studied the impact of regulatory tools such as financial disclosures and fiduciary duties on consumer welfare. She also empirically studies the way households manage their financial ebbs and flows and engage in mental accounting. Some of her recent work considers how artificial intelligence, and consumer fintech more broadly, is affecting consumers and raises distributional concerns. Her paper “The Input Fallacy” was the winner of the 2022 AALS Scholarly Papers Competition. She is a recipient of the 2022 Junior Faculty Grant and the Richard Paul Richman Center for Business, Law and Public Policy Grant.

Gillis joined the Columbia Law faculty in 2020 after completing a S.J.D. degree at Harvard and pursuing a Ph.D. in economics. At Harvard, she was a John M. Olin Fellow in Empirical Law and Finance, a Terence M. Considine Fellow in Law and Economics, and a Program on Negotiations Fellow. She clerked for Deputy Chief Justice Hanan Melcer of the Supreme Court of Israel.
