MORALES MOSQUERA, Miguel Ángel  e  ZAMUDIO GOMEZ, Nancy Eugenia. Is there a relationship between bank concentration and financial stability?. Ens. polit. econ. [online]. 2013, vol.31, n.71, pp.36-53. ISSN 0120-4483.

This article examines the relationship between financial stability and bank concentration in the Colombian economy for the period 1994-2009. To evaluate this relationship, a dynamic unbalanced panel was constructed in which the financial stability and concentration indicators controlled by macroeconomic factors are related, as well as the variables that reflect the characteristics of the banks and that are associated with the risk variable. The results show that there were improvements in terms of financial stability as the banking system consolidated over the past twenty years. However, this relationship is not linear, and it is possible to find an optimal level of consolidation.
