We analyze strategic experimentation in which information arrives through fully revealing, publicly observable “breakdowns.” When actions are hidden, there exists a unique symmetric equilibrium that involves randomization over stopping times. With two players, this is the unique equilibrium....

We prove that if $f$ is a positive $C^2$ function on a convex compact set $X$ then it becomes strongly convex when multiplied by $(1+|x|^2)^N$ with $N$ large enough. For $f$ polynomial we give an explicit estimate for $N$, which depends on the size of the coefficients of $f$ and on the lower bound...

Dans cet exposé je discuterai les conditions nécessaires d’optimalité (principe de maximum et les relations de sensibilité) pour les problèmes de contrôle à l’horizon infini impliquant un coût avec ou sans le facteur d’actualisation. Dans ce cadre les difficultés majeures sont liées au choix des...

We measure the persuasive effects of slanted news and tastes for like-minded news, exploiting cable channel positions as exogenous shifters of cable news viewership. Channel positions do not correlate with demographics that predict viewership and voting, nor with local satellite viewership. We...

This paper analyzes the effect of the tick size on market quality variables with a view of making specific predictions of what to expect from the SEC pilot program on tick size. We make three analyses with two different datasets. One dataset is a cross-section of over 2000 assets selected from the...

We develop a theory of constrained communication about corporate social behavior between a NGO and an imperfectly informed stakeholder. We seek to understand when and why the NGO reveals socially-beneficial activities (good news) or socially detrimental ones (bad news). The model provides two main...

We present a descriptive model of choice that incorporates neurobiological constraints, representational structures and costs into a traditional economic framework. An individual's behavior is fully described by two, in principle observable, primitives: an individual's neural/mental capacity and an...

Has rising trade integration between the U.S. and China contributed to the polarizationof U.S. politics? Analyzing outcomes from the 2002 and 2010 congressional elections, we detect an ideological realignment that is centered in trade-exposed local labor markets and that commences prior to the...

Gaussian process regression consists in predicting a continuous realization of a Gaussian process, given a finite number of observations of it. When the covariance function of the Gaussian process is known, or when the statistician selects and fix a given covariance function, this prediction is...
