The Internationalization Of Equity Markets

This timely volume addresses three important recent trends in the internationalization of United States equity markets: extensive market integration through foreign investment and links among stock prices around the world; increasing securitization as countries such as Japan come to rely more than ever before on markets in equities and bonds at the expense of banks; and the opening of national financial systems of newly industrializing countries to international financial flows and institutions, as governments remove capital controls and other barriers. Eight essays examine such issues as the current extent of international market integration, gains to U.S. investors through international diversification, home-country bias in investing, the role of time and location around the world in stock trading, and the behavior of country funds. Other, long-standing questions about equity markets are also addressed, including market efficiency and the accuracy of models of expected returns, with a particular focus on variances, covariances, and the price of risk according to the Capital Asset Pricing Model.

This introduction to a forthcoming NBER volume on 'The Internationalization of Equity Markets' argues that the existing finance literature has in some respects not kept pace with world trends. Most empirical studies fail to take due account of the diversity of assets offered by countries around the world, the diversity of locales in which investors live, and the diversity of institutional peculiarities that characterize the markets in which assets and investors are brought together. Four of the papers in the volume are econometric studies of asset pricing and home-country bias in internationally integrated equity markets. The other four examine such issues as emerging markets, country funds, trading volume, location, taxes, controls, and other imperfections in international markets.

China’s equity markets internationalization process started in the early 2000s but accelerated after 2012, when Chinese firms’ shares listed in Shanghai and Shenzhen gradually became available to international investors. This paper studies the effects of the post-2012 internationalization events by comparing the evolution of equity financing and investment activities for: (i) domestic listed firms relative to firms that already had access to international investors and (ii) domestic listed firms that were directly connected to international markets relative to those that were not. The paper finds large increases in financial and investment activities for domestic listed and for connected firms, with significant aggregate effects. The evidence also suggests the rise in firms’ equity issuances was primarily and initially financed by domestic investors. International investors’ portfolio holdings in Chinese equity markets and ownership in firms increased markedly only once Chinese firms’ locally issued shares became part of the MSCI Emerging Markets Index.

The authors study international financial integration analyzing firms from various countries raising capital, trading equity, and cross-listing in major world stock markets. Using a large sample of 39,517 firms from 111 countries covering the period 1989-2000, they find that, although international financial integration increases substantially over this period, only relatively few countries and firms actively participate in international markets. Firms more likely to internationalize are from larger and more open economies, with higher income, better macroeconomic policies, and worse institutional environments. These firms tend to be larger, grow faster, and have higher returns and more foreign sales. While changes occur with internationalization, these firm attributes are present before internationalization takes place. The results suggest that international financial integration will likely remain constrained by country and firm characteristics.
