Transmission of Volatility between Stock Markets
This article investigates why, in October 1987, almost all stock markets fell together despite widely differing economic circumstances. The authors construct a model in which "contagion" between markets occurs as a result of attempts by rational agents to infer information from price changes in other markets. This provides a channel through which a "mistake" in one market can be transmitted to other markets. The authors offer supporting evidence for contagion effects using two different sources of data. Article published by Oxford University Press on behalf of the Society for Financial Studies in its journal, The Review of Financial Studies.
