Abstract We show that equity market liberalizations, on average, lead to a 1% increase in annual real economic growth. The effect is robust to alternative definitions of liberalization and does not reflect variation in the world business cycle. The effect also remains intact when an exogenous measure of growth opportunities is included in the regression. We find that capital account liberalization also plays a role in future economic growth, but, importantly, it does not subsume the contribution of equity market liberalizations. Other simultaneous reforms only partially account for the equity market liberalization effect. Finally, the largest growth response occurs in countries with high-quality institutions.
