INSTITUTIONS,BANKING DEVELOPMENT,AND ECONOMIC GROWTH

Does the institutional environment affect the causal relationship between banking development and economic growth? In the theoretical section of this paper, we develop an endogenous growth model where the institutional environment is captured through two indicators: judicial system efficiency and easiness of informal trade. We show that an improvement in the institutional environment has two effects. First, it intensifies the causality direction from banking to economic growth through a reduction in defaulting loans. Second, it reduces the interest rate spread. In the empirical section of the paper, we find bidirectional causality when analyzing 22 Middle Eastern and North African countries over the period 1984–2004. The first causality, which runs from banking development to economic growth, is more intense in countries with more developed institutional environment. The second causality runs from economic growth to banking and indicates that a more developed economy has a more developed banking system.
