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,...

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...

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...

This paper considers a population divided into two significantly-sized groups regarding the preferences its members have about a single public good. The public good equilibrium amount is that of the majority group in such a way that it is far from the Pareto-efficient one. This allows us to...

The dominance of income over commodity taxation for the single consumer case, implies that if the consumer is asked about what tax she would pay to bear a given tax burden, she would choose income taxation. This paper provides a version of this preference for income taxation for the case of...

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...
