Book excerpt: Volatility spillover among major equity markets has long fascinated academicians and researchers alike. This paper presents an elaborate survey and analysis of the literature on the subject. Review of extant studies on various basis such as markets studied, methodology employed, among others has important implications for various stakeholders. We report that there has been wide variation in results because different studies have examined different markets using wide range of financial econometric methodologies. Some have considered only volatility or both volatility and spillover. Still others have incorporated the impact of global financial crisis on volatility spillover. Future researchers should examine if there is any volatility spillovers between various sectors of an economy, between different financial markets of the same economy, amongst same sectors of different markets, probe whether size effect is relevant, identify the transmission channels of volatility spillover, enumerate reasons behind volatility spillover, examine asymmetric volatility responses among stock markets and can use more advanced econometric techniques.
