How financial markets affect long run growth : a cross country study

Empirical studies on new growth theory have tended to ignore financial policy's role in development. The author provides evidence that the initial level of financial development is positively associated with a country's later GDP growth rate, after controlling for the effect of the starting value of human capital and the investment rate. A country that starts with a more developed financial system tends to grow faster because it can make more efficient use of resources. It can do so through several channels, including better evaluation and monitoring of firms, lower transaction costs for financial intermediation, and externalities generated from information collected and processed in financial markets. Policy reform that fosters financial development also has a significant positive effect on the growth rate of real GDP. The empirical evidence presented for 50 developing countries tends to reinforce a classical theme of development economics: the importance of human capital and financial markets.
