This paper proposes a tractable framework to analyze fiscal space and the dynamics of government debt, with a possibly binding zero lower bound (ZLB) constraint. Without the ZLB, a greater primary deficit unambiguously raises debt. However, debt need not explode: When R G - φ, where φ is the...

Optimal debt management can be thought of in three stages. First, if taxes are lump sum and the other conditions for Ricardian equivalence hold, then the division of government financing between debt and taxes is irrelevant, and the whole level of public debt is indeterminate from an optimal-tax...

Persistent budget deficits have increased economists' interest in theories and evidence about fiscal policy. This paper develops the Ricardian approach and contrasts it with standard models. The discussion considers from major theoretical objections to Ricardian equivalence-finite lifetimes,...

We study the interactions between sovereign debt default and maturity choice in a setting with limited commitment for repayment as well as future debt issuances. Our main finding is that under a wide range of conditions the sovereign should, as long as default is not preferable, remain passive...

We address the question of whether and how a sovereign should reduce its external indebtedness when default is a significant possibility, with a particular focus on whether a sovereign should buy back or dilute existing long-term sovereign bonds. Our main finding is that when reduction of debt...

In this chapter, we use a benchmark limited-commitment model to explore key issues in the economics of sovereign debt. After highlighting conceptual issues that distinguish sovereign debt as well as reviewing a number of empirical facts, we use the model to discuss debt overhang, risk sharing,...
