The aging of the population shakes the confidence in the economic viability of pay-as-you-go social security systems. We demonstrate how in a political-economy framework the shaken cofidence leads to the downsizing of the social security-system, and to the emergence of supplemental individual...

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...

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 demonstrates how time consistency of the Ramsey policy - the optimal fiscal and monetary policy under commitment - can be achieved. Each government should leave its successor with a unique maturity structure for the nominal and indexed debt, such that the marginal benefit of a...

We develop a model that captures important features of debt crises of the Brazilian type. Its applicability to Brazil lies in the fact that (1) macro fundamentals were sound in the wake of the crisis (e .g., a non-negligible primary surplus, a relatively low debt/GDP ratio, low inflation, etc.);...

We develop a model that captures important features of debt crises of the Brazilian type. Its applicability to Brazil lies in the fact that (1) in Brazil the macro fundamentals were sound (e.g., a primary surplus, a relatively low debt/GDP ratio, etc.); and (2) in the Brazilian case the trigger...

We develop a stylised model of multiple equilibria, with country risk spreads at the focus of the analysis. Fears that the country default on its debt triggers a reversal in the direction of inflows of international financial capital raise interest-rate spreads and thus the cost of servicing the...

This paper surveys the recent literature on the theory of macroeconomic policy. We study the effect of various incentive constraints on the policy making process, such as lack of credibility, political opportunism, political ideology, and divided government. The survey is organized in three...

Bequest constraints have played a major role in discussions of debt neutrality but their welfare implications were not sufficiently dealt with in the literature. In this paper we focus on the welfare implications of bequest constraints. We found that when institutional constraints to the...

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...
