This paper investigates the effect of bank competition and financial stability on economic growth by examining panel-data
from 38 European countries over 2001 to 2017. Bank competition is measured with the Boone indicator, and bank stability with Z-scores and non-performing
loan ratios, all at the country level. This study employs a fixed-effect estimator, as well as a system generalized method of moment (GMM) estimator
to control unobserved heterogeneity, endogeneity, the dynamic effect of economic growth, and reverse causality in its estimation. Results show that
bank stability significantly contributes to economic growth in Europe. Economic growth falls during crisis periods (both the global financial crisis
and the local banking crisis), highlighting the importance of a resilient banking system during crisis periods. Moreover, empirical outcomes show that
lower banking competition supports economic growth and increases financial stability. This study provides a framework for banks and regulators to boost
economic growth through the channel of banking stability.
