This study scrutinises the role of institutional quality in the linkage of financial development and economic growth in 21 Middle East and North African (MENA) countries. Using the common correlated effect mean pooled approach and annual data for the period 1980–2012, we find that not all measures of financial development promote economic growth in the absence of institutional quality, but they all augment growth in the presence of institutional quality. Furthermore, we find that foreign direct investment enhances the growth of MENA countries by the development of financial markets.
