Tiivistelmä:The cost frontier function is estimated on a bank sample from new European Union (EU) members from Central and Eastern Europe (CEE) and the Baltics (CEEB) for the 1998-2007 period. The paper explores the significance of the heterogeneity problem in banking efficiency research by using stochastic frontier techniques. The results imply that environmental variables can only partly control for the presence of heterogeneity in the sample. By using the 'true' random-effects model by Greene (2005), there are found to result in considerably smaller differences in average country efficiency levels, which implies that CEEB countries represent a relatively homogeneous group in terms of bank performance.
