This paper is concerned with the incentive properties of the Matthew Effect by which since Merton [1968] one is usually describing the various cumulative advantages that obviously affect academic competition. We introduce a model of sequential contests in which the agents that have initially...

We study the development of a duopoly industry -evolution of firm capacities and competitive behavior- in a continuous-time real-options model of capacity investment. Our methodology allows the evaluation of investment options and exercise rules in a strategic setup. In the initial industry...

We study a simple duopoly model of preemption with multiple investments and instantaneous Bertrand competition in a stochastically growing market. Different patterns of equilibria may arise, depending on the importance of the real option effect. If the average growth rate of the market is close...

In the 1970s, Thomas C. Schelling proposed a model which claimed to show that a high degree of spatial segregation can result from individual preferences which do not in themselves aim to achieve such a degree of collective segregation. A perverse effect seems therefore to occur. However, the...

We consider a dynamic version of sender-receiver games, where the sequence of states follows an irreducible Markov chain observed by the sender. Under mild assumptions, we provide a simple characterization of the limit set of equilibrium payoffs, as players become very patient. Under these...

We develop a three stage game model composed of a regulator and two firms. These firms compete on the same market where they offer the same homogeneous good, and can invest in R&D to lower their emission/output ratio. By means of a tax per-unit of pollution and a subsidy per-unit of R&D level,...

Nous étudions expérimentalement le comportement de sujets confrontés, dans une population, à une multiplicité de jeux du dilemme du prisonnier, suivant que les interactions sont bilatérales ou multilatérales. Nous observons, (i), une coopération significativement supérieure en cas de...
