We conduct a series of Cournot duopoly market experiments with a high number of repetitions and fixed matching. Our treatments include markets with (a) complete cost symmetry and complete information, (b) slight cost asymmetry and complete information, and (c) varying cost asymmetries and...

This paper experimentally studies two simple interventions aimed at increasing public goods provision in settings in which accurate feedback about contributions is not available. The first intervention aims to exploit lying aversion by requiring subjects to send a non-verifiable ex post...

I develop a general framework for markup and markdown estimation that allows for profit sharing along value chains without making assumptions on conduct between vertically related firms. I derive the conditions under which the markup and markdown estimates relate to the firms' equilibrium...

Do self-formed teams perform better than other team structures? Using unique data from Virgo, a Nobel-prize-winning scientific organization with self-formed teams, first, I uncover new evidence on team formation and performance. Then, I develop a structural model to i) estimate which teams...

We analyze platform competition where user data is collected to improve adtargeting. Considering that users incur privacy costs, we show that the equilibrium level of data provision is distorted and can be inefficiently high or low: if overall competition is weak or if targeting benefits are...

Platforms often display their products ahead of third-party products in search. Is this due to consumers preferring platform-owned products or platforms engaging in self-preferencing by biasing search towards their own products? What are the welfare implications? I develop a structural model of...
