Stochastic OLG Models, Market Structure, and Optimality
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 particular case in which markets fail to be even sequentially complete and provide a characterization when the criterion of efficency is weakened to ex post Pareto optimality.
