In this article, we consider an ordered Stackelberg framework. In such a context, leadership is the preferred position. We show, using a linear model, with constant average costs, that the larger the number of a firm's followers is, the larger its profit. However, as the number of firms...

We show in this article the existence of endogenous rationing in a leader-follower duopoly with differentiated products. The duopolists compete in both prices and quantities and each may choose a price-quantity pair within the residual demand it faces in equilibrium. Therefore they are involved...

[fre] Avec la croissance apparaissent de nouveaux besoins de protection de l'environnement. Nous étudions les règles d'investissement optimales lorsque les décisions sont irréversibles et les dépenses indivisibles. Une attitude myope consistant à ne prendre en compte que les données...

[eng] Spatial competition and distortuns of localization. Under incomplete information. . We study a model of spatial duopoly competition with sequential entry on a segment in the choice of locations (stage 1 of the game) and then simultaneous competition in delivery prices (stage 2). The second...

We model capacity-building investments in a homogeneous product duopoly facing uncertain demand growth. Capacity building is achieved through the addition of production units that are durable and lumpy and whose cost is irreversible. While building their capacity over time, firms compete à la...

We model investments in capacity in a homogeneous product duopoly facing uncertain demand growth. Capacity building is achieved through adding production units that are durable and lumpy and whose cost is irreversible. There is no exogenous order of moves, no first-mover or second-mover...
