بهره وری هزینه در میان بانک های کارت اعتباری

Credit card banks produce a single, relatively homogeneous output, permitting exceptionally clean empirical tests of cost efficiency. The high net interest margins and fees on credit card loans also suggests a large potential for managerial slack or expense preference behavior, possibly fostering a wider range of cost efficiency than observed for general-purpose banks. This paper presents estimates of cost efficiency for a sample of monoline credit card banks over the period 1984–1993; the findings are similar to those previously reported for general-purpose banks. We also explore empirical correlates of the estimated cost efficiency.
