This paper deals with public debt in open economies, extending Diamond's overlapping generations model to deal with a small openeconor as well as an international eciuilibrium of two large economies. It focuses on the intergenerational welfare redistributions caused by an increase in the public...

This paper studies the political-economic equilibrium of a two-period model with overlapping generations. In each period the policy is chosen under majority rule by the generations currently alive. The paper identifies a "sustainable set" of values for public debt. Any amount of debt within this...

The Traditional View (TV) of large deficits and debt is they have large economic costs, save in a recession and early recovery, because they crowd out investment and lower future income, and taken to extremes, can cause inflation and even a financial crisis. The TV has been challenged, most...

Recent developments in public finance in the analysis of dynamic government debt policies have emphasized effects on the distribution of real resources across generations. At the same time, macroeconomists have emphasized the importance of the length of the time horizon over which agents...

Many issues in macroeconomics, such as the level of the steady state interest rate, or the dynamic effects of government deficit finance, depend crucially on the horizon of economic agents. This paper develops a simple analytical model in which such issues can be examined and in which the...

We introduce a solution technique for the study of discrete time stochastic models populated by long-lived agents. We introduce aggregate uncertainty and complete markets into a 'perpetual-youth' model of a kind first studied by Olivier Blanchard and we show that the pure-trade version of the...

This paper develops a tractable overlapping generations model that is useful for analyzing both the short and long run impact of fiscal policy and social security. It modifies the Blanchard (1985)/Weil (1987) framework to allow for life/cycle behavior. This is accomplished by introducing random...

We investigate how the ability of the government to depart from budget balance and issue debt expands the set of equilibria that can be supported using lump-sum tax-transfer instruments. We show how this depends on the restrictions that exist on the capacity to tax and make transfer payments,...

Can governments roll their debt over forever in dynamically efficient economies, and thus avoid the need to raise taxes? While the answer is a clear no under certainty, it depends, under uncertainty, on whether public debt provides intergenerational insurance. When it does not, rollover is not...

We propose a clientele-based model of the yield curve and optimal maturity structure of government debt. Clienteles are generations of agents at different lifecycle stages in an overlapping-generations economy. An optimal maturity structure exists in the absence of distortionary taxes and...
