Banking efficiency in the Visegrad Group according to Data Envelopment Analysis

The situation in the banking industry is very difficult all around the world. The Central Europe and especially countries of the Visegrad Group have to keep up with a lot of changes - historical development, new rules of the European Commission or the 2008 crisis. There are many studies which evaluate banking efficiency in the Visegrad Group. Almost all of these studies evaluate the efficiency under certainty and just for small sample. The problem of the studies are missing data so they chose just some banks. This may cause imprecise results. The aim of this paper is to determine the efficiency of the banking industry in Visegrad Group for a big group of banks (57 banks). The technical efficiency of banks in the Visegrad Group is estimated for years from 2009 to 2013. The special DEA models for calculations with the missing data are used. The development of calculated technical efficiency is analysed in the cross section between the units and in the time. Also the influence of the risk variable is measured as well.
