Market Concentration in Europe: Evidence from Antitrust Markets

An increasing body of empirical evidence is documenting trends toward rising concentration, profits, and markups in many industries around the world since the 1980s. Two major criticisms of these studies is that concentration and market shares are poorly measured at the national industry level while firm level revenues are a poor indicator of product sales. We use a novel database that identifies over ...

Rent Price Control – Yet Another Great Equalizer of Economic Inequalities? Evidence from a Century of Historical Data

The long-run U-shaped patterns of economic inequality are standardly explained by basic economic trends (Piketty’s r>g), taxation policies, or “great levelers,” like catastrophes.

We hypothesize that rent control could decrease overall housing wealth, lower incomes ...

Quantifying the Externalities of Renewable Energy Plants Using Wellbeing Data: The Case of Biogas

Although there is strong support for renewable energy plants, they are often met with local resistance. We quantify the externalities of renewable energy plants using well-being data. We focus on the example of biogas, one of the most frequently deployed technologies besides wind and solar. To this end, we combine longitudinal household data with novel panel data on more than 13, 000 installations ...
