This paper empirically analyses the impact of government ownership on competition in monopoly and duopoly markets. We use the European Airline Industry as a laboratory. In our empirical strategy we exploit two sources of exogenous variations that allow us to cleanly filter out the effect of government ownership on the likelihood of exit. First, we study government ownership that was triggered by a...

I exploit a recent legal reform in Germany which specifically aimed to increase price competition among real estate agents by raising the cost salience of sellers. I find that the reform backfired and real estate agents exploited the transition to increase their total commission rate by 0.3...
The European Emissions Trading System (EU-ETS) is the key policy tool of the EU to reduce GHG emissions. To prevent carbon leakage, most of the emission permits have been allocated for free in the industrial sector.

We show that pass-through increases with competition, going from 50% in monopoly to around 80%...
