International transmission of stock market movements: a wavelet analysis

This study investigates the international transmission mechanism of stock market movements via wavelet analysis. While GARCH-type models have mainly been used in most recent research in this area, the discrete wavelet decomposition is used in this study to propose a new methodology for investigating the dynamics and the potential interaction in international stock markets. Using the data on daily stock indices from the USA and Korea, strong evidence is found for price as well as volatility spillover effects from the developed stock market to the emerging market, but not vice versa.
