We employ the Luenberger productivity indicator to estimate productivity growth and its decomposition into technical change and efficiency change components for savings banks sectors in 10 EU countries between 1996 and 2003. The Luenberger indicator requires less restrictive assumptions than...

We apply specifications of the random parameters stochastic frontier cost function model to estimate bank efficiency. This class of model appears to resolve the long standing problem of confounding inefficiency and heterogeneity. Mean cost efficiencies from random models are higher by as much as...

The Luenberger productivity indicator is employed to estimate and decompose productivity change in a sample of cooperative banks operating in 10 EU member states. An average annualised productivity growth of 2.59% is reported between 1996 and 2003, though there is heterogeneity in growth rates...
