Recent literature suggests that stock market liberalisation has positive effects on macroeconomic growth and private investment. However, econometric relations are largely dependent on the inclusion of higher income countries in such samples, which quite conceivably limits the relevance for lower income nations. Indeed, some evidence in this study indicates that stock market development has a more positive impact on growth for greater levels of per capita GDP. Similarly, lagged equity price appreciation seems to boost private investment growth, but only in rich countries. Curiously, neither financial nor legal development variables, which are more serviceably relevant than initial income, seem to be mitigating factors, but these data imply subdued enthusiasm regarding emerging equity market development.
