Foreign Speculators and Emerging Equity Markets

We propose a cross-sectional time-series model to assess the impact of market lib- eralizations in emerging equity markets on the cost of capital, volatility, beta, and correlation with world market returns. Liberalizations are defined by regulatory changes, the introduction of depositary receipts and country funds, and structural breaks in equity capital flows to the emerging markets. We control for other eco- nomic events that might confound the impact of foreign speculators on local equity markets. Across a range of specifications, the cost of capital always decreases after a capital market liberalization with the effect varying between 5 and 75 basis points. THROUGHOUT HISTORY AND IN MANY MARKET ECONOMIES, the speculator has been characterized as both a villain and a savior. Indeed, the reputation of the speculator generally depends on the country where he does business. In well- functioning advanced capital markets, such as the United States, the specu- lator is viewed as an integral part of the free-market system. In developing capital markets, the speculator, and in particular the international specula- tor, is looked upon with many reservations. Recently, many so-called "emerging" markets have opened up their capital markets to foreign investors, creating an ideal laboratory for examining the impact of increased foreign portfolio investment in developing equity mar- kets. Our main focus is the impact on expected equity returns-the cost of equity capital. However, we also examine the effects of increased foreign
