I work on microeconomic theory and behavioural economics, with a special focus on information economics.
I concluded my Ph.D. in economics at Columbia University in 2021.

I co-organise the UCL Centre for Theoretical and Behavioural Economics and its seminar series.
I am also the director of the UCL Experimental Laboratory for Finance and Economics.

Working Papers

Speed, Accuracy, and Complexity
1st draft Feb 2024; updated June 2024; revise and resubmit at Econometrica
| Working Paper

To infer problem complexity, look not at time, but rather at how choices are affected when incentives change.

Sequential Sampling Equilibrium
1st draft Sept 2020; updated Nov 2023; revise and resubmit at American Economic Review
| Working Paper

A new equilibrium solution concept where players sequentially sample to resolve strategic uncertainty over their opponents' distribution of actions delivers predictions on the joint distribution of actions, beliefs, and decision times.

Incentives and Strategic Behaviour
with Teresa Esteban-Casanelles; 1st draft Feb 2020; updated Jan 2025; revise and resubmit at Experimental Economics
| Working Paper

The incentive level in games affects choices and beliefs about the opponent by inducing greater cognitive effort. (An earlier version circulated with the title "The Effect of Incentives on Choices and Beliefs in Games: An Experiment")

The Informational Role of Online Recommendations: Evidence from a Field Experiment on MovieLens
with Guy Aridor, Ruoyan Kong, Daniel Kluver, Joseph Konstan; 1st draft Nov 2022; revise and resubmit at Marketing Science
| Working Paper | Extended Abstract (EC 2023)

A longitudinal randomised controlled trial on a movie recommendation platform identifies an informational channel of recommendations on consumption by examining how recommendations affect consumers' beliefs and how these determine consumption choices. (An earlier version circulated with the title "The Economics of Recommender Systems: Evidence from a Field Experiment on MovieLens")

Statistical Mechanism Design: Robust Pricing, Estimation, and Inference
with Bruno A. Furtado; 1st draft Mar 2020; updated May 2024; revising for submission
| Working Paper

A mechanism designer with a sample of consumers' types can conduct valid inference on profit and regret and use our toolkit to compare mechanisms.

Revealing Complexity
with Salvatore Nunnari and Julen Zarate-Pina
| Extended Abstract (Draft coming soon)

We leverage the fact that minor changes to relative incentives exert a disproportionately larger impact on choices in complex problems than in simpler ones to investigate how different features of the decision-making environment contribute to the complexity of choice across various domains of interest.


Publications

Retractions: Updating from Complex Information
with Jonathan Libgober and Jack Willis; Review of Economic Studies
| Working Paper | Published Version

Retractions — provision of indirect information — are treated as more complex than equivalent direct information and subjects infer less from them. (An earlier version circulated as a NBER working paper with the title "Learning versus Unlearning: An Experiment on Retractions")

Quantal Response Equilibrium with a Continuum of Types: Characterization and Nonparametric Identification
with Evan Friedman; Games and Economic Behavior
| Working Paper | Published Version

We provide a complete characterisation of the set of QRE in a class of binary-action games with a continuum of types, including global games, which we leverage to develop nonparametric tests.

The Dynamics of Instability
with César Barilla; Theoretical Economics
| Working Paper | Published Version

Even in absence of short-term gains, players with diametrically opposed interests want to generate instability to advance their interests.

Recommenders’ Originals: The Welfare Effects of the Dual Role of Platforms as Producers and Recommender Systems
with Guy Aridor; International Journal of Industrial Organization
| Working Paper | Published Version

The ability of platforms to bias their recommendations can lead to vertical foreclosure, but separating recommendation and production is not always welfare improving.
