In a nutshell (You can download my full research profile here and here) 

Protecting consumers from high prices and low variety (of unsustainable / unhealthy food) when producers and retailers are powerful

Research Field & Methodology (You can download my full research profile here)

• 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 the causal analysis using economic theory, statistics, and big data sets.

Research Questions

• Do minimum wages increase real income of households? 

• Do retail mergers decrease or increase prices?

• What are the sources of cost savings from retail mergers: buyer power or efficiency gains (warehouses + transport costs)?

• How much of the cost increases do retailers pass-on to consumers in form of prices and variety? 

• Do multi-product firms exploit switching costs from brand loyalty? 

• What role do switching costs from brand loyalty play in cases of mergers and taxation? 

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