Bank Mergers in Spatially Differentiated Markets

Abstract

[Abstract] This paper studies the incentives of banks to merge when competing in differentiated markets. Localized competition effects and spatial competition variables can play a key role in defining the patterns of consolidation in this sector. We consider a model where banks compete in distinct spaces of depositor's characteristics. Regional merger is the outcome of the merger game if the spatial scope of demand is low and/or accessibility of services is not costly outside the home region. Otherwise, cross-regional merger is the outcome of the game. The results are consistent with the recent evolution of banking systems in many developed countries.
