We revisit the issue of fiscal procyclicality in commodity-rich nations -commodity republics in the nomenclature of this paper. Since commodity prices are plausibly a main driver of fiscal policy outcomes in these countries, we focus on the behavior of fiscal variables across the commodity...

This paper develops a model of optimal government debt maturity in which the government cannot issue state-contingent bonds and cannot commit to fiscal policy. If the government can perfectly commit, it fully insulates the economy against government spending shocks by purchasing short-term...

Recent academic papers have shown that the Japanese sovereign debt situation is not sustainable. The puzzle is that the bond rate has remained low and stable. Some suggest that the low yield can be explained by domestic residents' willingness to hold Japanese government bonds (JGBs) despite its...

We study optimal fiscal policy in a small open economy (SOE) with sovereign and private default risk. The SOE's government uses linear taxation to fund exogenous expenditures and uses public debt to inter-temporally allocate tax distortions. We characterize a class of environments in which the...

What determines the sustainability of sovereign debt? We develop a model where myopic governments seek popularity but can nevertheless commit credibly to service external debt. They do not default when debt is low because they would lose access to debt markets and be forced to reduce spending;...

This paper explores the interaction between fiscal policy and unemployment. It develops a dynamic economic model in which unemployment can arise but can be mitigated by tax cuts and public spending increases. Such policies are fiscally costly, but can be financed by issuing government debt. In...

We construct quarterly series of the revenues, expenditures, and debt outstanding for Japan from 1980 to 2010, and analyze the sustainability of the fiscal policy. We pursue three approaches to examine the sustainability. First, we calculate the minimum tax rate that stabilizes the debt to GDP...

We identify the major public debt overhang episodes in the advanced economies since the early 1800s, characterized by public debt to GDP levels exceeding 90% for at least five years. Consistent with Reinhart and Rogoff (2010) and other more recent research, we find that public debt overhang...

We model and calibrate the arguments in favor and against short-term and long-term debt. These arguments broadly include: maturity premium, sustainability, and service smoothing. We use a dynamic equilibrium model with tax distortions and government outlays uncertainty, and model maturity as the...

Governments in emerging markets often behave like a "tormented insurer," trying to use non-state-contingent debt instruments to avoid cuts in payments to private agents despite large fluctuations in public revenues. In the data, average public debt-GDP ratios decline as the variability of...
