We study a trading process for a pure exchange economy with overlapping generations. This process is based on the maximization, at each stage, of a collective benefit (or surplus). We show that this process converges to a Pareto-optimal allocation. This extends the second fundamental convergence...

Available characterizations of the various notions of stochastic dominance concern continuous random variables. Yet, discrete random variables are often used either in pedagogical presentations of stochastic dominance or in experimental tests of this notion. This note provides complete...

This paper presents another definition of substitutes and complements. It follows a dual approach using the Luenberger's benefit function. The benefit function measures the amount of a reference bundle that an individual would be willing to give up to move from a given utility level to any...
