Time-varying beta and the Asian financial crisis: Evidence from the Asian industrial sectors

This paper empirically investigates the effects of the Asian financial crisis of 1997-98, and the period immediately afterwards, on the time-varying beta of four industrial sectors (chemical, finance, retail and industry) of Indonesia, Singapore, South Korea, and Taiwan. We apply daily data from 1992 to 2002 and the bivariate MA-GARCH model (BEKK) to create the time-varying industrial betas. Results provide evidence of the influence of the Asian financial crisis, and the period after, on the time-varying industrial betas of these countries. These results may have implications for investors who are interested in portfolio risk management.
