I am an Associate Professor (with tenure) at MINES Paris, PSL University.

Research Field & Methodology

• My field is the analysis of firm size, market power, competition, and public policies at different levels of supply chains. 

• To that end, I use so called "Structural Models of Empirical IO": which allow causal inference using economic theory, statistics, and big data.

Research Questions

• How do firm size and illegal cartels affect prices and variety (at different levels of the supply chain)?

• How much of the cost increases (e.g., energy prices or minimum wages) do retailers pass-on to consumers in form of prices and variety? 

• Which public policy is most effective to  compensate consumers for a loss in their purchasing power?

• Do firms exploit brand loyalty as a source of market power? What is the effect of brand loyalty in cases of mergers, taxation, and subsidies?
