We propose a new model for the variance between multiple time series, the Regime Switching Dynamic Correlation. We decompose the covariances into correlations and standard deviations and the correlation matrix follow a regime switching model; it is constant within a regime but different across...

We examine the equity market price interdependence between Australia, on one hand, and Japan, US, UK, Hong Kong, Singapore, Taiwan and Korea, on the other hand, based on Hacker and Hatemi-J (2003) bootstrap causality tests with leveraged adjustments. We cover the period January 1, 1993 to...

In this paper we check the relationschip between the yields of the Colombian bonds traded in the (secondary) internal market and the yields of the sovereign global securities for the sample period 1999-2001. The hypothesis we maintain is that, under the assumption of capital mobility, it should...
