We study the differential impact of exchange rate volatility on cost efficiency and market structure when banks have non-trivial exposures to foreign currency operations. First, we document that cost efficiency estimates are both severely downward biased by 30% on average and generally not rank...

This paper investigates the cost efficiency of Russian banks with regard to their heterogeneity in terms of ownership form, capitalization and asset structure. Using bank-level quarterly data over the period 2005–2013, we perform stochastic frontier analysis (SFA) and compute cost efficiency...
