An n-variable structural vector auto-regression (SVAR) can be identified (up to shock order) from the evolution of the residual covariance across time if the structural shocks exhibit heteroskedasticity (Rigobon (2003), Sentana and Fiorentini (2001)). However, the path of residual covariances is...

In this paper new results are documented regarding the short term evolution of global short term interest rates. Much work has been carried out concerning the evolution of interest rates over long time scales, on the order on one month or greater. However high frequency data has only been...
