window analysis

Measuring the efficiency of banking systems: A relational two-stage window DEA approach. MPRA Paper 55671, University Library of Munich, Germany.

This study examines the efficiency of banking systems in seventeen OECD countries over the period 1999-2009. For the purpose of our analysis we introduce a window-based version of two relational two-stage DEA models. Furthermore, we apply different versions of the additive and the multiplicative decomposition approaches in order to capture the trends of the efficiencies over the examined period.
