摘要：The current paper provides new insights on competition degree among 2,024
commercial, cooperative and savings banks from the 28 European Union states during 2005-
2015. Bank-level Lerner index, its e¢ ciency-adjusted form and Boone indicator are the
computed indices, with total output consisting in loans, customer deposits and securities.
The estimates of marginal costs result from solving a Fourier áexible form of translog cost
function. The banks included in the sample remain very competitive over time with the
commercial and cooperative ones displaying the highest competitiveness. Non-OECD, uppermiddle
income and Eurozone states have a more competitive banking sector comparing to
their counterparts.
