This paper investigates product-specific scale economies of banks with respect to off-balance sheet operations. The cost benefits from the non-separability of outputs available to banks that imply the role of OBS activities on bank scale economies are also examined. We further test whether the...

We use a stochastic frontier production model to estimate the technical efficiency of the 21 more industrialized countries in the world for the wide period from 1966 to 2007. A Cobb-Douglas function with labour and capital as inputs, GDP as output and an efficiency term with exponential...
