We revisit a classical theme of general equilibrium theory, namely the continuity of the Walras correspondence. Using a remarkable theorem due to Fort (1951) which has widely been used in recent literature on game theory, we are able to prove the generic continuity of the price equilibrium-set...

This paper investigates fair (i.e., envy free and efficient) allocations in an overlapping generations economy without production and with two - period lived agents. We show that there exists a conflict between no-envy and efficiency when all generations have identical preferences. This conflict...

This paper examines the representation and explicit description of social welfare orders on infinite utility streams. It is assumed that the social welfare orders under investigation satisfy upper asymptotic Pareto and anonymity axioms. We prove that there exists no real-valued representation of...

We consider a standard one-agent decision-making problem under risk and we address the following question: under what conditions is utility maximization equivalent to 'risk' minimization, where the measure of risk used by the decision-maker is a conservative coherent risk measure?

We study the nature (i.e., constructive as opposed to non-constructive) of social welfare orders on infinite utility streams, and their representability by means of real-valued functions. We assume finite anonymity and introduce a new efficiency concept we refer to as asymptotic density-one...
