In this paper we provide necessary and sufficient conditions for the existence of a Cournot equilibrium when demand is rho-linear and firms are identical and produce under constant returns to scale. We focus on inelastic and convex demand which yields non concave profit functions.We show that...

In the traditional Cournot model producers influence each other’s decisions through revenue earned in the product market. Rosen (1965) introduced the notion of a coupled constraints equilibrium which allowed players to affect their rivals’ strategy space as well. Krawczyk (2005) applied this...

We show that Miller and Pazgal.s (2001) model of strategic delegation, in which managerial incentives are based upon relative performance, is affected by a non-existence problem which has impact on the price equilibrium. The undercutting incentives generating this result are indeed similar to...
