Capital, risk and efficiency tradeoffs in Cameroonian banking
This paper analyzes the relationship between capital, risk and efficiency for a sample of 10 Cameroonian banks between 2014 and 2020. To reach the authors’ target, they specify a system of equations and estimate it using the two stage least squares panel data estimator technique. The empirical analysis shows that increases of bank capital do not reduce risk taking in Cameroonian commercial banks. Moreover, cost...
