Recurrent crises in emerging markets and in advanced economies in the last decades cast doubt about the ability of financial liberalization to meet the aims of sustainable economic growth and development. The increasing importance of financial markets and financial efficiency criterion over economic decisions and policies since the 1980s laid down the conditions of the development process of emerging market economies. Numerous crises experienced thereafter gave rise to flourishing work on the links between financialization and economic development. Several decades of observations and lessons can now be integrated into economic and econometric models to give more sophisticated and multivariable approaches to financial development with respect to growth and development issues. In the markets-based and private-enterprise dominated world economy, two conditions for a successful growth-enhancing financial evolution can at least be brought fore: macroeconomic stability and consistent supervision.
