I am an Assistant Professor of Economics at the University of St. Gallen.

My main interests are in industrial organization, particularly contracts, auctions, and contests.

I also study incentives in blockchain markets and in cryptographic protocols.

I am affiliated with the Zurich Center for Market Design.

 

Publications

[8] Working for References (with Curtis Taylor).
American Economic Journal: Microeconomics, 15(3), 2023, 33-77.

IdeaJob references incentivize worker effort under moral hazard, but are underprovided because firms do not internalize their incentive benefits.

Quantitative Economics, 14(2), 2023, 419-470. [Replication Files].

Economic Theory, 74, 2022, 1103–1140. (Online first: 2019.)

Games, Volume 7(3), 2016, p. 25.

Working Papers

Mechanism Design with Information Leakage (with Marek Pycia and Haoyuan Zeng)
First Version: October 2025.

IdeaOptimal mechanisms must be redesigned when information about the history of play can leak across agents or stages.

Price Gouging and the Monopoly Option (with Curtis Taylor)
First Version: October 2024. Latest Version: October 2025.

First Version: January 2025. Latest Version: August 2025.

IdeaStudies candle auctions experimentally and in the field, comparing bidding behavior and efficiency under classic incentive structures versus modern auction formats.

Front-Running and Candle Auctions (with Alistair Stewart)
