Wpływ wielkości banku na jego efektywność: badania dla krajów Europy Środkowo-Wschodniej

Abstrakt

Although there is a growing body of literature on the impact of bank size on itsstrategy, efficiency, profitability and stability, the results are still inconclusive. Themain advantages of large banks are their capability for product and geographicaldiversification, ability to bear the cost of technological changes and easier accessto financial resources. On the other hand, small banks have a good understandingof local markets, use soft information on their clients more effectively, are basedon relationship banking model, and have much simpler organizational structure.The aim of this paper is to analyze the impact of bank size on its efficiency in Centraland East European countries. For that purpose, all commercial banks fromCEE countries were divided into four groups, depending on their size (expressedin absolute and relative terms). Technical and scale efficiency scores for the period2004–2013 were calculated using Data Envelopment Analysis. The main conclusionis that in CEE countries bank size affects the efficiency, particularly if thesize is expressed in absolute terms. There is a positive relationship between banksize and its technical efficiency (especially above a certain limit). The relationshipbetween bank size and scale efficiency is nonlinear: the smallest and the largestbanks have higher scale inefficiency.
