### Summary
- Author: Tamon Asonuma
- Publication date: March 16, 2016
- Core finding: Emerging countries that have defaulted in the past are more likely to default again in the future than non-defaulters with the same external debt-to-GDP ratio.
- Scope: Explains repeated defaults and restructurings occurring in short periods using a dynamic stochastic general equilibrium framework with explicit modeling of renegotiations between a defaulting country and its creditors.
- Quantitative headline: The equilibrium probability of default for a given debt-to-GDP level is weakly increasing with the number of past defaults.
- Additional quantitative association: Lower recovery rates (high NPV haircuts) are associated with increases in spreads at renegotiation.

### Stylized facts documented
- Repeated defaults and restructurings occur in short periods for some emerging countries.
- Past default history increases future default likelihood even controlling for the same external debt-to-GDP ratio.
- Recovery rates and haircut magnitude are linked to market spreads at renegotiation.

### Model and quantitative analysis
- Framework: Dynamic stochastic general equilibrium model that explicitly models renegotiations between a defaulting country and its creditors.
- Main model implication:
  - The equilibrium probability of default for a given debt-to-GDP level is weakly increasing with the number of past defaults.
- Renegotiation implication:
  - Lower recovery rates (high NPV haircuts) correspond to increases in spreads at renegotiation.
