A model developed by Hamilton and Susmel (1994), the switching autoregressive conditional heteroskedastic (SWARCH) model, which is a more general specification than the...

We use high-frequency interest-rate data for a group of Latin American and Asian countries to analyze the behavior of volatility through time. We focus on volatility comovements across countries. Our analysis relies on univariate and bivariate switching volatility models. We compare the results...

In this paper we use weekly stock market data for a group of Latin American countries to analyze the behavior of volatility through time. We are particularly interested in understanding whether periods of high volatility are correlated across countries. The analysis uses both on univariate and...
