We extended the Cole and Kehoe model (1996) by adding trade and debt denominated in national currency. We then evaluated some external debt defaults and steep national currency devaluations occurred during last decades. Although default is unlikely, steep devaluation has been repeatedly...

Research has shown that seeking to benefit the own group can under certain conditions achieve the opposite result when the beneficiary inter-group cooperation opportunity is undermined with a prisoners' dilemma type tribal interest conflict. In this paper, I reconsider this problem using...

This paper studies the impact of income inequality on sovereign spreads under elastic labor and endogenous taxation. We first document that high pre-tax income inequality is associated with high spreads both across countries and across U.S. states. We then develop a sovereign default model with...

Policy prescriptions for managing natural resource windfalls are based on the permanent income hypothesis: none of the windfall is invested at home and saving in an intergenerational SWF is dictated by smoothing consumption across different generations. Furthermore, with Dutch disease effects...

We examine the spillover effects between sovereigns and banks in a model with a heterogeneous banking system. An increase in sovereign's default risk affects financial intermediaries through two channels in this model. First, banks' funding costs might increase, inducing higher interest rates on...

While the Court of Justice of the European Union has approved the European financial assistance schemes, the haircut of public creditors appears as a possible next step of escalation in the euro debt crisis. This article explores the legal boundaries set by the EU Treaty on such debt...

I show that reputation alone can sustain nominal sovereign debt, which is subject to both the risks of default and opportunistic devaluations. Nominal debt combined with a countercyclical exchange rate policy allows more hedging against shocks than real savings if markets are incomplete. Thus,...

The aim is to show how and when government insolvency implies a fixed exchange rate regime crisis. To model these issues I try to unify a stylized macroeconomic model with a standard micro agent behavior toward asset pricing. The equilibrium condition between demand and supply of public debt,...

A commitment to an ex-post inefficient bailout can be ex-ante optimal because it can mitigate rollover problems without an actual bailout. Reinforcement between illiquidity and insolvency create beneficial multiplier effects that overwhelm the adverse effect of moral hazard. Committing to bail...

This paper studies the interaction between fiscal commitment and sovereign default risk in a model with optimal taxation and government spending. A time-inconsistency problem arises in our framework as the government cannot credibly commit to its future tax policies. As a result, it chooses...
