Notes:               A measure of market power in the banking market. It compares output
                     pricing and marginal costs (that is, markup). An increase in the
                     Lerner index indicates a deterioration of the competitive conduct of
                     financial intermediaries.
                     
                     A measure of market power in the banking market. It is defined as the
                     difference between output prices and marginal costs (relative to
                     prices). Prices are calculated as total bank revenue over assets,
                     whereas marginal costs are obtained from an estimated translog cost
                     function with respect to output. Higher values of the Lerner index
                     indicate less bank competition. Lerner Index estimations follow the
                     methodology described in Demirgüç-Kunt and Martínez Pería (2010).
