September 2016Self-Fulfilling Debt Crises: A Quantitative Analysis
with Luigi Bocola: w22694
This paper uses the information contained in the joint dynamics of government’s debt maturity choices and interest rate spreads to quantify the importance of self-fulfilling expectations in sovereign bond markets. We consider a model of sovereign borrowing featuring endogenous debt maturity, risk averse lenders and self-fulfilling rollover crises á la Cole and Kehoe (2000). In this environment, interest rate spreads are driven by economic fundamentals and by expectations of future self-fulfilling defaults. These two sources of default risk have contrasting implications for the debt maturity choices of the government. Therefore, they can be indirectly inferred by tracking the evolution of the maturity structure of debt during a crisis. We fit the model to the Italian debt crisis of 2008-20...
January 2016Political Economy of Sovereign Debt: A Theory of Cycles of Populism and Austerity
with Mikhail Golosov, Ali Shourideh: w21948
We study optimal fiscal and redistributive policies in an open economy without commitment. Due to its redistributive motives, the government’s incentive to default on its external debt is affected by inequality. We show that in equilibrium the economy endogenously fluctuates between two regimes. In the first regime, the government borrows from abroad, spends generously on transfers and keeps the inequality low. In the second regime, it implements austerity-like policies by cutting transfers, reducing foreign debt and increasing the inequality. The equilibrium dynamics resembles the populist cycles documented in many developing countries.
