We study infinitely repeated anonymous random matching games played by communities of players, who only observe the outcomes of their own matches. It is well known that cooperation can be sustained in equilibrium for the prisoner's dilemma, but little is known beyond this game. We study a new...

I propose a model of international trade with liquidity constraints. If firms must pay a fixed entry cost in order to access foreign markets, and if they face liquidity constraints to finance these costs, only those firms that have sufficient liquidity are able to export. A set of firms could...

This paper uses a model of international trade under duopoly to investigate under which conditions a large country’s entrance on world markets can lead to lower and less quality diversity available to consumers rather than more. In our partial model, autarky quality is proportional to the...

In this paper, we consider a symmetric contest game in which agents compete to increase their share of a risky rent. We show that a symmetric equilibrium always exists, and that it is unique under constant or decreasing absolute risk aversion. We then exhibit interpretable conditions so that...

CTL (Cytotoxic T. Lymphocytes) destroy virally infected cells and tumor cells via the secretion of lytic molecules stored in intracellular granules. They are key components of the anti-cancer immune response and it is therefore crucial to study in depth, and possibly enhance, their biological...

This paper deals with a natural stochastic optimization procedure derived from the so-called Heavy-ball method differential equation, which was introduced by Polyak in the 1960s with his seminal contribution [Pol64]. The Heavy-ball method is a second-order dynamics that was investigated to minimize...

Recent advances in economic theory, largely motivated by experimental findings, have led to the adoption of models of human behavior where a decision-maker not only takes into consideration her own payoff but also others’ payoffs and any potential consequences of these payoffs. Investigations of...
