Economic growth and financial depth: the role of institutional quality
摘要
We explore the potential nonlinear impact of economic growth on financial depth, an important topic that is still largely absent from the existing literature. Using a panel dataset of 122 countries, we apply a dynamic panel threshold regression model with endogeneity to examine this nonlinearity. Our findings reveal evidence of nonlinearity driven by a threshold effect related to institutional quality. Specifically, we demonstrate that the impact of economic growth on financial depth becomes positive and significant once countries surpass a certain level of institutional quality. These results underscore the importance of enhancing institutional quality to effectively leverage economic growth as a catalyst for financial market development.
