We extend and refine Aguiar and Amador (2019)'s contraction approach to Eaton and Gersovitz (1981)'s sovereign debt model. In particular, we encompass time-varying interest rates and growth. We show that, when long-term interest rates exceed growth, equilibrium is unique and can be computed via...

Fluctuations in sovereign bond yields display a large global component which is associated with a rise in uncertainty. We build a model of sovereign default in which shocks to the level and to the volatility of the world interest rate help to account for this phenomenon. We calibrate the model...

International data suggests that fluctuations in the level and volatility of the world interest rate (as measured by the US treasury bill rate) are positively correlated with both the level and volatility of sovereign spreads in emerging economies. We incorporate an estimated time-varying...

Empirical studies suggest that fluctuations in the level and volatility of the world interest rate (as measured by the US treasury bill rate) affect sovereign spreads in emerging economies. We incorporate an estimated time-varying process for the world interest rate (with both level and...
