The geographical network of bank organizations: issues and evidence for Italy

The evolution of the banking industry has always been affected by recurrent waves of technological, regulatory and organizational changes. All such changes have significant effects on the spatial organization of banks, the interconnectedness of geographical credit markets and the core-periphery structure of banking industry. In this chapter, we review the literature on the effects of geographical distances between the key actors of the credit market (the borrowing firm, the lending branch, the lending bank, and rival banks) on lending relationships and interbank competition. Using the metrics and graph techniques for network analysis we then provide evidence concerning the evolving geographical network of bank organizations in Italy.
