There currently exists in the literature several continuous-time one-factor models for short-term interest rates. This paper considers a wide range of these models that are nested into one general model. These models are approximated using both a discrete-time model and a model that accounts for aggregation effects over time, and are estimated by both the […]
This paper analyses how Canadian financial firms manage short-term interest rate risk through the use of BAX futures contracts. The results show that the most effective hedging strategy is, on average, a static strategy based on linear regression that assumes constant variances, even though dynamic models allowing for time-varying variances are found to have superior explanatory power.
