### Summary
- Strong evidence that interest rates and bond yield movements exhibit both stochastic volatility and unanticipated jumps.
- Frequent jumps raise the question whether a premium for jump risk is embedded in observed bond yields.
- The paper identifies a class of jump-diffusion models that successfully approximate the term structure of interest rates of emerging markets.
- Parameters of the term structure are reconciled with associated bond yields by estimating volatility and jump risk premia in highly volatile markets.

### Methods and Model Evaluation
- Estimation approach: simulated method of moments (SMM).
- Model class: jump-diffusion models with stochastic volatility and unanticipated jumps.
- Finding on model adequacy: all variants of models that do not incorporate stochastic volatility and unanticipated jumps cannot generate the non-normalities consistent with observed interest rates.

### Key Quantitative Results
- Jumps occur (8,10) times a year in Argentina and Brazil, respectively.
- The size and variance of these jumps is reported as statistically significant.
