Financial markets in the Visegrad countries have undergone several changes in lending business over the past decade. This study evaluates the effi ciency of the largest commercial banks by focusing on their lending decisions using Data Envelopment Analysis. First, we defi ne the concept of effi ciency, then we analyse loan effi ciency between 2007 and 2013. The results indicate that average effi ciency declined. When we studied the loan effi ciency in each country separately, we found that Hungarian banks had the lowest effi ciency while the highest effi ciency was achieved mainly by Czech banks. The results of the study also suggest that effi ciency is positively related to profi tability and capital adequacy, and negatively related to the share of non-performing loans, which confi rms the bad management hypothesis.
INTRODUCTIONOver the past decade, financial markets in the Visegrad countries (V4) have undergone several changes that have significantly affected the performance of their banks. One of the consequences of the global financial crisis was the growth of non-performing loans (NPL) and the growth of their share on total gross loans. For example, the average share of NPL in banks, covered by this paper, rose from 5 to 10% between 2007 and 2013. The subject of NPLs has attracted more attention in recent years. Several studies examined bank failures and found that assets quality was an indicator of insolvency (Demirgüç-Kunt 1989; Barr -Siems 1994) since banks had a high level of NPLs before bankruptcy. These authors found that when the volume of bad loans increased, the banks' ability to increase their performance declined. Besides NPLs, one important aspect in the measurement of bank performance is efficiency. This affects the stability of the banking industry and thus the efficiency of the entire financial system. Banking sectors are still the primary form of financial intermediation in the V4 1 countries, being the major channel for the mobilisation of domestic savings and their transformation into a major source of external capital to firms. Banks are key players in the payment systems; therefore, the development of the banking sector's efficiency is crucial for the growth of economies in the V4 countries.According to Resti (1996), at the macroeconomic level, bank efficiency represents a socially optimal objective. It reduces the costs of financial intermediation, the transfer of funds from savers to producers. Consequently, central banks are seriously interested in the accomplishment of operating practices and market equilibrium that grant the maximum productive efficiency, provided that this does not result in a monopoly, which would expropriate consumers from the advantages due to the reduction in average costs. Of course, given some crisis situations, it may be optimal to postpone the search for efficiency, concentrating on the defence of the system stability and preventing dangerous "domino effects" that can arise, when the less productive institutions are forced to quit the market in a traumatic...
