Aim of the study is to test the influence of Russian banks’ ownership  structure over their frontier efficiency through Banzhaf power index.

Description:

In this study we analyzed the relationship between ownership structure and efficiency of commercial banks. Ownership structure was included into the model with Banzhaf power index. Efficiency was measured with the cost frontier efficiency curve. The efficiency model was tested using the sample of 100 largest Russian commercial banks.

Results:

We concluded that the high level of ownership concentration leads to the high cost frontier efficiency of large Russian banks.
