China’s current economic situation versus the former. If China sneezes who will survive? Using a balanced data set of 78 European commercial banks over the period 2006-2016, this study examines the existence of non-linear relationships between market concentrations and banks’ risk appetite. Developed by Hansen (1999). Select bad debt ratio, credit risk tolerance ratio, and cat non-fat to proxy liquidity risk. There are two main findings. The results of our analysis indicate that the threshold effect is indeed present. Furthermore, our results suggest a significant positive relationship between market concentration and bank credit risk. This positive effect diminishes when the market concentration exceeds a certain threshold. Overall, the study found evidence that banks’ risk behavior differs according to market concentration. The results are robust under additional testing. These findings have strong implications for regulators.
