For a general class of pure exchange OLG economies under uncertainty, we provide a complete characterization of the efficency properties of competitive equilibria when markets are only sequentially complete and the criterion of efficency is conditional Pareto optimality. We also consider a...

In this paper we propose a new tâtonnement process of short-period equilibria with rational expectations: current period prices move proportionally to current period excess demand while future prices are formed according to the perfect foresight hypothesis. It is shown that this process is...
