Thesmar holds a BA in physics and economics from École Polytechnique, and a PhD from the Paris School of Economics.

Current Research Focus: Thesmar's research is in corporate finance. One first area is valuation, with an emphasis on forecasting rules and valuation methods. This line of research employs survey data as well as laboratory experiments in order to shed light on the efficiency of the capital budgeting process. Another related area is corporate governance: He shows that ESG investment does not contradict value creation. A third line of research argues that finance benefits the economy by allocating capital to the right projects: He finds that this contribution is very large.
