We test whether capital account liberalization led to higher economic growth using de jure measures of capital account and financial current account openness for 94 nations, from 1950 (or independence) onward. We argue that measurement error, differing time periods used, and collinearity among independent variables account for conflicting results in prior scholarship. We use pooled time-series, cross-sectional OLS and system GMM estimators to examine economic growth rates, 1955–2004. Capital account liberalization had a positive association with growth in both developed and emerging market nations. We confirm that equity market liberalization has an independent effect on economic growth.

In this paper, we use a unique long-run dataset of regulatory constraints on capital account openness to explain stock market correlations. Since stock returns themselves are highly volatile, any examination of what drives correlations needs to focus on long runs of data. This is particularly true since some of the short-term changes in co-movements appear to reverse themselves (Delroy Hunter 2005). We argue that changes in the co-movement of indices have not been random. Rather, they are mainly driven by greater freedom to move funds from one country to another. In related work, Geert Bekaert and Campbell Harvey (2000) show that equity correlations increase after liberalization of capital markets, using a number of case studies from emerging countries. We examine this pattern systematically for the last century, and find it to be most pronounced in the recent past. We compare the importance of capital account openness with one main alternative explanation, the growing synchronization of economic fundamentals. We conclude that greater openness has been the single most important cause of growing correlations during the last quarter of a century, though increasingly correlated economic fundamentals also matter. In the conclusion, we offer some thoughts on why the effects of greater openness appear to be so much stronger today than they were during the last era of globalization before 1914.(This abstract was borrowed from another version of this item.)
