Working papers:
with Konrad Adler
Tacit collusion among firms is not necessarily easier when firms are owned by the same investor. Going from separate to common ownership actually sometimes has a pro-competitive effect.
with Alkis Georgiadis-Harris and Maxi Guennewig
Since Diamond and Dybvig (1983), banks have been viewed as inherently fragile. We challenge this view in a general mechanism design framework with limited commitment.
Oprimal Financial Intermediation
with Maxi Guennewig
We revisit the Diamond-Rajan model of financial intermediation and demonstrate that a bank with an optimal financing structure is immune to runs.

A reduction of borrowers' exposure to aggregate risk, through economic or policy changes, can paradoxically increase banks' systematic risk.
