We characterize optimal taxation of foreign capital and optimal sovereign debt policy in a small open economy where the government cannot commit to policy and seeks to insure a risk averse domestic constituency. The expected tax on capital is shown to vary with the state of the economy,...

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...

We investigate the macroeconomic effects of fiscal consolidations based upon government spending cuts, transfers cuts and tax hikes. We extend a narrative dataset of fiscal consolidations, with details on over 3500 measures for 16 OECD countries. We show that government spending cuts and cuts in...

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...

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...

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...

A shift in taxes or in government spending (a "fiscal shock") at some point in time puts a constraint on the path of taxes and spending in the future, since the government intertemporal budget constraint will eventually have to be met. This simple fact is surprisingly overlooked in analyses of...

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.);...

This chapter is on quantitative models of sovereign debt crises in emerging economies. We interpret debt crises broadly to cover all of the major problems a country can experience while trying to issue new debt, including default, sharp increases in the spread and failed auctions. We examine the...

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...
