Dans cet article nous effectuons une analyse econometrique du secteur d'activite "distribution du courrier" de la Poste. Le but est d'obtenir une information quantitative concernant les characteristiques technologiques de ce secteur. Plus particulierement, nous examinons les elasticites des...

This paper presents a patent choice model allowing strategic decisions in a sequential game with two agents: a patentholder, who perfectly knows thecharasteristics of the market, and a potential entrant who has no information about the value of demand. We study several Perfect Bayesian...

It is shown that a fixed cost of nominal price changes enhances the ability of firms to collude in an ologopolistic market for a homogeneous good. Nevertheless, harsh price competition with firms making no profit remains a possible outcome. The analysis focuses on stable symmetric steady states...

This paper extends the theory of irreversible investment under uncertainty to incorporate capacity constraints and uncertainty on the input price. In addition, no restriction on the demand elasticity value is imposed. Assuming input price follows a geometric Brownian motion, the optimal...

Organizations require discretionary decision making to be delegated and to be under only partial scrutiny from supervisors. This introduces the possibility for agents to use their discretionary power to their own advantage and in detriment to the organization. We model this situation by...

Consider a general equilibrium framework where the marginal cost of extraction from several deposits of an exhaustible resource is constant in terms of an inexhaustible perfect substitiute and differs between deposits. The instantaneous rate of productionfrom the inexhaustible resourcce is...

This paper presents a simple model of local telecommunications market when two access technologies, landline and wireless, are available. The two technologies differ in their cost structures and in the services they provide to consumers; specifically, the wireless technology allows its...
