This study examines the efficiency performance of the minority-owned banks (MOBS) as multiproduct firms relative to that of the nonminority banks (NMOBs) using a highly flexible nonparametric approach. Since MOBS and NMOBs employ distinct technologies the efficiency indices for the two groups...

Two alternative approaches of efficiency measurement, nonparametric and statistical, are employed to calculate three types of efficiency indexes for the U.S. beer industry over the period 1950-1986. The results indicate that the beer industry was operating at a high level of pure technical...

This paper derives the scale and scope economy measures for the U.S. cooperative banks for the years 1989, 1990 and 1991 using the translog cost function. The results suggest that cooperative banks can save costs through increasing their size and diversifying their outputs
