We study sequential parimutuel betting markets with asymmetrically informed bettors, usingan experimental approach. In one treatment, groups of eight participants play twenty repetitionsof a sequential betting game. The second treatment is identical, except that bettors are observedby other...

We adopt an evolutionary approach to investigate whether and when condi-tional cooperation can explain the voluntary contribution phenomenon oftenobserved in public goods experiments and in real life. Formally, conditionalcooperation is captured by a regret parameter describing how much an...

We study the role of whistleblowing in the following inspectiongame. Two agents who compete for a prize can either behave legallyor illegally. After the competition, a controller investigates the agents’behavior. This inspection game has a unique Bayesian equilibriumin mixed strategies. We...

We develop a theory of tax reforms for a setting with multi-dimensional heterogeneity amongst taxpayers and multiple economic decisions that are all subject to fixed and variable costs. The theorems in this paper provide a complete characterization of the conditions under which Pareto- or...

This paper deals with the introduction of stock options in an (dy-namically) incomplete securities market.

This paper begins with a survey of the literature on the political economy approaches to labor income taxation. We focus on recent progress made by examining in detail the specific properties of non-linear taxes derived in the context of voting. Next, we present new results on the existence of...

This paper studies frequent monitoring in a simple infinitely repeated game with imperfect public information and discounting, where players observe the state of a continuous time Brownian process at moments in time of length Δ. It shows that efficient strongly symmetric perfect public...

This paper studies repeated games where the time of repetitions of the stage game is not known or controlled by the players. Many economic situations of interest where players repeatedly interact share this feature, players do not know exactly when is the next time they will be called to play...

I develop a model of contracting under reciprocal altruism accounting for some evidence which is paradoxical from the point of view of neoclassical models with selfish actors. My model predicts the crowding-out effect observed in the Trust Game with the possibility of a fine; for the Control Game...
