Common Volatility in International Equity Markets

Journal of Business & Economic Statistics, 1993, vol. 11, issue 2, 167-76
In this article, the authors take advantage of the time-varying structure of stock-returns variances to investigate whether two international stock markets share the same volatility process. They use a test recently developed by R. F. Engle and S. Kozicki (1990). This test is also used to assess the validity of a one-factor autoregress ive conditional heteroskedasticity model. The authors find that some international stock markets have the same time-varying volatility.
