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...

Is there a role for debt beyond curing overaccumulation of capital? Does dynamic efficiency and the infeasibility of debt Ponzi schemes eliminate any Pareto-improving role for a government in a competitive economy with complete markets? Is there an optimal maturity structure of public debt?...

We analyse debt policy in a two-period, two-sector overlapping generations model with Leontief technologies. We find that debt, issued to transfer resources to the initially old, could be welfare improving in the new steady state for an economy which satisfies the usual conditions for dynamic...

In this paper debt policy in a two-period, two-sector overlapping generations model with Leontief technologies has been analysed. It has been found that debt, issued to transfer resources to the initially old, could be welfare improving in the new steady state for an economy which satisfies the...

We show that (i) dynamic inefficiency may be empirically relevant in a modified Diamond model with imperfect competition, (ii) if fiscal policy is used to avoid inefficiency and maintain an optimal capital intensity, the required debt ratio will be inversely related to the growth rate, and (iii)...

In recent contributions, Weizsäcker (2014) and Summers (2014) maintain that mature economies accumulate too much capital. They suggest large and lasting public deficits as a remedy. This paper argues that overaccumulation cannot occur in an economy with land. It presents novel data of aggregate...
