Before Sherman and Ladino (see the readings) did their full analysis of their banking system, they might have analyzed a smaller data set to determine what sort of conclusions they might have drawn. Suppose banks B11, B12, B13, B14, and B15 were all located nearby so became the DMU for this smaller data set. In addition, a choice has to be made on the inputs and outputs. Suppose the inputs chosen where tellers and expenses and the outputs were deposits, and loans. This gives the following data:
How do your results match up with the full study? Are your conclusions radically different?
