Most integrated models of the Covid pandemic have been developed under the assumption that the policy-sensitive reproduction number is certain. The decision to exit from the lockdown has been made in most countries without knowing the reproduction number that would prevail after the deconfinement....

Across societies, humans punish norm violations. To date, research on the antecedents and consequences of punishment has largely relied upon agent-based modeling and laboratory experiments. Here, we report a longitudinal study documenting punishment responses to norm violations in daily life (k = ...

We consider 2-player zero-sum stochastic games where each player controls his own state variable living in a compact metric space. The terminology comes from gambling problems where the state of a player represents its wealth in a casino. Under standard assumptions (e.g. continuous running payoff...

We study an auction that maximizes the expected social surplus under an upper-bound constraint on the seller’s expected revenue, which we call a revenue cap. Such a constrained-efficient auction may arise, for example, when (i) the auction designer is “pro-buyer”, that is, he maximizes the weighted...

We study how a decision maker uses his reputation to simultaneously influence the actions of multiple receivers with heterogenous biases. The reputational payoff is single-peaked around a bliss reputation at which the incentives of the average receiver are perfectly aligned. We evidence two...

I examine how incentives for refutation affect publication quality. I build a sequential model of public experimentation with two scientists, a researcher and a refuter. The researcher chooses when to publish a result confirming a hypothesis, with a probability that the result has type I error. The...

This paper proposes an analysis of strategic communication on platforms by candidates during an electoral campaign. A candidate's platform in a (possibly) multidimensional policy space is fixed, but is imperfectly known by voters. A candidate strategically decides the emphasis he puts on the...

A simple equilibrium model is presented which permits the joint study of optimal Central Bank prudential, monetary and balance sheet policies in the pre and post 2008 Crisis periods. It explains the new policies—the purchase of risky securities (QE), payment of interest on reserves (IR) and use of...

Inference by exclusion, or the ability to select a correct course of action by systematically excluding other potential alternatives, is a form of logical inference that allows individuals to solve problems without complete information. Current comparative research shows that several bird, mammal...
