We develop a general equilibrium stochastic OLG model with heterogenous households. Households differ with respect to their productivity. Productivity depends stochastically on parents' unobservable investment in their child's human capital and an aggregate productivity shock. We introduce a...

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...

The rational prodigality argument, which often serves to justify social security, is considered in a second-best tax framework with endogenous labor supply. Rational prodigality renders the familiar policies time inconsistent. We analyze time consistent policies and show that a wage tax suffices...

The book compares funded and unfunded pension schemes. This is done within a simple overlapping generations framework.

The authors outline a public pension reform where contribution rates are reduced to zero over a very long horizon and in a Pareto-improving fashion.

We propose an extended PAYG social security system that conditions pension benefits on the aggregate wage sum and on the wage of one’s children. The latter increases parents’ incentives to provide their children with good within-family education. However, since wages depend stochastically on...
