I am a fifth-year Ph.D. student in Economics at Universitat Pompeu Fabra (UPF) , under the supervision of Prof Antonio Penta. My research interests span behavioral economics, microeconomic theory and experimental economics, with a focus on model misspecification, cooperation, and repeated games.

The Importance of Being Even: Restitution and Cooperation [Draft] (with Maria Bigoni, Marco Casari, Andrzej Skrzypacz, Giancarlo Spagnolo)
We study, empirically and theoretically, how restitution helps restore cooperation after a breach or an exploratory defection. Restitution strategies propose a return to cooperation by cooperating against defection, and condition actions on the balance between cooperation given and received. We reanalyze experimental data from repeated Prisoner's Dilemma games and find empirical support for restitution strategies in general, and for a strategy we name Payback, in particular. Besides explaining how subjects deal with conflicts, accounting for restitution strategies helps reconcile discrepancies between theory and experiments—such as the widespread use of non-equilibrium strategies like Tit-for-Tat and the limited predictive power of risk dominance under imperfect monitoring.
Choice by Contextual Associations [Draft coming soon] (with Jose Apesteguia)
It has been amply shown that choice behavior is context-dependent. Evidence from the cognitive sciences suggests that this dependency may be driven by implicit associations. In this paper, we propose and study a choice-based model of contextual associations. We start by formalizing contexts by the set of concepts it contains. We then introduce associations by way of the implicit relationship between alternatives and concepts, which directly impacts the utility evaluation of alternatives. We study the empirical content of the model, establish conditions for identification, characterize its comparative statics, and propose several extensions. We provide an application to probabilistic voting, showing that our model rationalizes how political competition contributes to the polarization of parties’ values, as emphasized in the empirical literature.
The trade-off between strategic risk and value of cooperation [Draft available upon request]
In this paper, I explore the trade-off between efficiency and strategic risk in the context of a repeated prisoner’s dilemma with imperfect public monitoring. Since with imperfect monitoring deviations can happen on the equilibrium path, to keep the value of cooperation high, players have to adopt more ``lenient” and ``forgiving” strategies, being more exposed to opportunistic behavior. For a broad class of one-dimensional public signals, I show that the maximal payoff achievable under a (symmetric) cooperative risk-dominant equilibrium is strictly lower than the maximal symmetric equilibrium payoff. Contrary to the perfect monitoring case, this holds even when the discount factor converges to 1.
