4. Empirical resultsWe design our empirical analyses as follows. First, we perform multivariate regression analyses by regressing the financial stabilityvariables on the diversification measures, the interaction terms between the diversification measures and the financial crisis perioddummies, and the control variables. We include the square of the diversification measure (Lag SQ non-interest income/TOR) in theregression equations to capture the possible non-linear relationship between bank diversification and financial stability. Second, tomitigate possible endogeneity problems, we also use 2SLS method. Additionally, we perform other robustness tests to confirm ourprimary results.
