Guillaume Saint-Jacques is a Ph.D Candidate at MIT Sloan, advised by Prof. Erik Brynjolfsson.
Guillaume's research interests broadly involve the economics of information technologies and digitization, and understanding how these change markets, organizations, and competition. In particular, he focuses on understanding the link between information technologies and the distribution of productivity and income, both across individuals and across businesses. Guillaume is especially interested in the analytics of large-scale datasets, such as government data, call details record data, and blockchains generated by cryptocurrency transactions in order to measure technological progress and its effects.
Prior to joining MIT, Guillaume studied economics at the École Normale Supérieure of Paris, and completed a Master's degree in economics at the Paris School of Economics. Under the supervision of Prof. Thomas Piketty, he wrote his Master's thesis on distortionary effects of the tax system on women’s labor supply and developed the first on-line tax reform simulator for the general public and lawmakers. He received his business education from the entrepreneurship action learning Master’s program at HEC Paris, and was involved in the early stages of a data analytics startup and a medical device start-up. For a year, he also taught as a French lecturer at the University of California, Los Angeles.
