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...

We study consumer surplus in a single market when a) there is a lower bound in the consumption of the outside good and b) the weights in the social welfare function given to consumers and firms are different. We assume quasilinear utility. When the lower bound constraint on the consumption of...

We consider a model in which agents choose a single niche to act. These niches could be different markets around the world or different contests. We look for the existence of a free entry equilibrium in which no agent wishes to switch to a different niche. When agents form a continuum,...

. This paper explores the effect of a tax reform which shifts from specific to value added taxation in a general equilibrium model with imperfect competition (both Cournot and Free Entry Oligopoly). Such tax reform is characterized through a rate of substitution between taxes. This...

La participación de las rentas del trabajo en los ingresos fiscales en España es superior a la participación de las rentas laborales en la renta nacional. Dado que la participación de las rentas laborales en la renta nacional es constante, la única manera de aproximar estas participaciones...

In 1946, Coase rejected Hotelling-Lerner's solution for financing a nationalized monopoly on the grounds that any tax structure could distort relative prices. In monopoly where two-part tariffs are infeasible, Coase suggested average cost pricing as a noninfenor solution to the above policy....
