Correlations in Price Changes and Volatility across International Stock Markets
研究东京、伦敦和纽约三大股市每日开盘收盘价，用ARCH模型发现纽约到东京、伦敦到东京、纽约到伦敦的波动溢出效应，但1987年10月前无反向溢出。
The short-run interdependence of prices and price volatility across three major international stock markets is studied. Daily opening and closing prices of major stock indexes for the Tokyo, London, and New York stock markets are examined. The analysis utilizes the autoregressive conditionally heteroskedastic (ARCH) family of statistical models to explore these pricing relationships. Evidence of price volatility spillovers from New York to Tokyo, London to Tokyo, and New York to London is observed, but no price volatility spillover effects in other directions are found for the pre-October 1987 period.
