Democracies around the world are making promises to the old at the expense of future generations. I interpret this as reflecting low altruism - a discount rate on children's utility greater than the world interest rate - and I examine the implications in a small open economy with overlapping...

Policy prescriptions for managing natural resource windfalls are based on the permanent income hypothesis: none of the windfall is invested at home and saving in an intergenerational SWF is dictated by smoothing consumption across different generations. Furthermore, with Dutch disease effects...

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?...

Aging societies will have to rely increasingly on private savings to finance retirement. The natural savings vehicles, stocks and bonds, are unfortunately lacking key risk-sharing features that are built into public retirement. Innovative government debt management can address this problem. The...

This paper analyzes the optimal level of public debt when taxes are used not only for funding public expenditures but also for correcting externalities from climate change. Taking into account externalities implies that the optimal policy deviates from tax smoothing. Provided cumulative marginal...

A rise in the ageing population is the current demographic challenge which is capable of pressuring the government to borrow more external funds in order to support domestic needs. This study aims to investigate the effects of the external debt of 36 upper-middle-income economies from 2000 to...

The paper analyzes the sustainability of governmental debt and its welfare properties in an overlapping generations economy with stochastic production and capital accumulation. In the absence of taxation, equilibria with positive debt generically converge to debtless eauilibria are typically...

The paper studies the dynamic allocation effects of tax policy in the context of an overlapping generations model of the Blanchard-Yaari type. The model is extended to allow for endogenous labor supply and three tax instruments: a capital income tax, labor income tax, and consumption tax....
