Working Papers
"Redistribution Through Market Segmentation" (with D. Barreto and V. Augias), May 26, Submitted
Extended Abstract in Proceedings of EC'24
We study how to segment monopolistic markets with a redistributive objective. These segmentations induce the seller to price progressively and may not maximise consumer surplus.
"Robust Regulation of Labour Contracts" (with Théo Durandard), Sept 25
R&R at the American Economic Review
Extended Abstract in Proceedings of EC'25
[PDF] [Supplemental Appendices] [arXiv]
Which contracts should a regulator authorise in moral hazard problems to minimise their worst-case regret? Simply impose a minimum piece-rate compensation.
"Imperfect Recall and AI Delegation" (with Eric Olav Chen and Sami Petersen), Nov 24
[PDF] [arXiv]
Simulating real tasks in testing and deleting AI's memory allows an evaluator to both screen misaligned AIs during testing and discipline their behaviour in deployment.
"Note on the Indeterminacy of Deliberate Preference Changes" (with N. Boissonnet), Nov 22

[PDF] [arXiv] [Journal version]
The forbidden fruit effect is when restrictions steer people’s desire toward the forbidden options. We axiomatise a choice model that rationalises it.

[PDF] [Journal version] [Older version with additional results]
Agents' preferences stem from their 'values', which they can change when becoming aware of new ones. We axiomatise deliberate preference changes rationalised by a metapreference.
Conference proceedings (peer-review)
"AI Testing Should Account for Sophisticated Strategic Behaviour" (with Vojtěch Kovařík, Eric Olav Chen, Sami Petersen, Vincent Conitzer), 2025
Forthcoming in Proceedings of the 39th Conference on Neural Information Processing Systems (NeurIPS-25)
This position paper argues that AI testing needs to account for AIs' strategic reactions and that game theory should thus inform testing design.
