About

Steve Tadelis is a Professor of Economics and Sarin Chair in Leadership and Strategy at Berkeley Haas. His research primarily revolves around e-commerce and the economics of the internet.

During the 2016-2017 academic year he was on leave at Amazon, where he applied economic research tools to a variety of product and business applications and worked with technologists, computer and ML scientists, and business leaders. During the 2011-2013 academic years he was on leave at eBay research labs, where he hired and led a team of research economists who focused on the economics of e-commerce, with particular attention to creating better matches of buyers and sellers; reducing market frictions by increasing trust and safety in eBay’s marketplace; understanding the underlying value of different advertising and marketing strategies; and exploring the market benefits of different pricing structures.

Aside from the economics of e-commerce, his main fields of interest are the economics of incentives and organizations, industrial organization, and microeconomics. Tadelis explored firm reputation as a valuable, tradable asset; the effects of contract design and organizational form on firm behavior with applications to outsourcing and privatization; public and private sector procurement and award mechanisms; and the determinants of trust.
