Notes:               A measure of degree of competition based on profit-efficiency in the
                     banking market. It is calculated as the elasticity of profits to
                     marginal costs. An increase in the Boone indicator implies a
                     deterioration of the competitive conduct of financial intermediaries.
                     
                     A measure of degree of competition, calculated as the elasticity of
                     profits to marginal costs. To obtain the elasticity, the log of
                     profits (measured by return on assets) is regressed on the log of
                     marginal costs. The estimated coefficient (computed from the first
                     derivative of a trans-log cost function) is the elasticity. The
                     rationale behind the indicator is that higher profits are achieved by
                     more-efficient banks. Hence, the more negative the Boone indicator,
                     the higher the degree of competition is because the effect of
                     reallocation is stronger. Estimations of the Boone indicator in this
                     database follow the methodology used by Schaeck and Cihák 2010 with a
                     modification to use marginal costs instead of average costs. Regional
                     estimates of the Boone indicator pool the bank data by regions (for
                     more information, see Hay and Liu 1997; Boone 2001; Boone, Griffith,
                     and Harrison 2005). (Calculated from underlying bank-by-bank data from
                     Bankscope)
