Using an overlapping generations model, this paper describes interactions between nai͏̈ve and sophisticated hyperbolic discounters in general equilibrium. The nai͏̈fes, who overestimate their future propensity to save and hence over-forecast the future equilibrium asset prices, are exploited...

We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium...
