Abstract:
Using the conditional Capital Asset Pricing Model (CAPM), this paper tests for the existence and pattern of contagion and capital market integration in global equity markets. Contagion is defined as significant excess conditional correlation among different countries' asset returns above what could be explained by economic fundamentals (systematic risks). Capital market integration is defined as the situation in which only systematic risks are priced. The paper uses a panel of sixteen countries, divided into three blocs: Asia, Latin America, and Germany-U.K.-U.S., for the period from 1990 through 1999. The results show evidence of contagion and capital market integration. In addition, contagion is found to be a regional phenomenon.

2. Transmission of Information Across International Equity Markets

Abstract:
This paper provides evidence of transmission of information from the U.S. and Japan to Korean and Thai equity markets during the period from 1995 through 2000. Information is defined as important macroeconomic announcements in the U.S., Japan, Korea, and Thailand. Using high-frequency intraday data, I focus the study on return volatility and trading volume because the implications of new information are much clearer than for returns. I find a large and significant association between emerging-economy equity volatility and trading volume and developed-economy macroeconomic announcements at short-time horizons. This is the first strong evidence of this sort of international information transmission. Previous studies' findings of at most weak evidence may be due to their use of lower frequency data and their focus on developed-economy financial market innovations as the measure of information.
