Abstract: | The banking/investment sector must deal with a new variable, Operational Risk, for explaining various recent crises and bankruptcies. Operational Risk, which can be defined briefly as the risk generated by possible failures of a entity's Information Systems (IS), must be measured, covered, mitigated and managed by applying a series of methodologies, each of which assumes that the IS of the bank operates at a certain Stage of Sophistication. The present study proposes a scheme of evolution that details the stages of enhancement in the sophistication of their IS that banking entities may implement, so as to be capable of capturing, mitigating and managing Operational Risk. Using econometric methods, we create a proxy variable to capture the IS Sophistication of each entity. Then, the factor of entity size has been analyzed, and the country effect is explored. Additionally, the importance of intangible assets is weighted, among others entity aspects. The entity size has been revealed as the variable with most influence on the plans formulated in this respect by European entities, against other variables also considered in the present study, such as the country effect or the importance of intangible assets. The work shows how IS decisions referring to Operational Risk management are very influenced by size. It could introduce competition differences in the European banking system. |
