This article proposes an identity regarding economic outcomes when producers maximize profits, with free entry and exit of firms. The identity links consumer and producer theory and leads to several results that contribute to understand what should - and should not - be expected under the...

Using a homogeneous and continuous utility function that represents a household's preferences, this paper proves explicit identities between most of the different objects that arise from the utility maximization and the expenditure minimization problems. The paper also outlines the homogeneity...

We propose a dynamic model with N-agents in an infinite time frame which allow us to adequately analyze conflicts. The dynamic...

By means of a suitable Bayesian game we study spot electricity markets from a structural point of view. We address the problem of individual and aggregate eficciency and we show how to value water from market observables. We compare the former to engineering methods and apply our methodology to...

Altruism, understood as the individual disposition to sacrifice personal income to improve someone else’s income can be a rational choice strategy which responds to different motivations, incentives and institutions, in a consistent way with the donor’s optimization logic. In this article we...
