The Luenberger productivity indicator is employed to estimate and decompose productivity change in a sample of co-operative banks operating in ten EU member states. An average annualised productivity growth of 2.59 percent is reported between 1996 and 2003, though there is heterogeneity in growth rates across countries. Generally speaking, productivity growth is driven by technological change. However, co-operative banks in southern European banking markets benefit as much from efficiency growth or catching-up with industry best practice. The results suggest that technology sharing arrangements and greater competition arising from deregulation are positive contributors towards productivity change.
