Resource Sharing in DEA

SB18.1 Equitable Allocation of Shared Costs in DEA Wade D. Cook, Moshe Kress --- York Univ., Schulich Sch. of Bus., 4700 Keele St., North York, Ontario, M3J 1P3 , Canada (wcook@bus.yorku.ca)

In many applications of DEA there is a common cost or resource¨ shared by all DMUs. The advertising expense for a product sold by¨ all branches would be an example. We present a DEA-based approach¨ for allocating that resource across the DMUs in an equitable way.

SB18.2 Separating Sales & Service Efficiencies in Bank Branches Moez Hababou --- York Univ., Schulich Sch. of Bus., 4700 Keele St., North York, Ontario, M3J 1P3 , Canada

Bank branch personnel perform a variety of transactions, some of¨ which are service related, while others pertain to sales. The¨ apportionment of their time between these 2 functions, however, is¨ not readily available as data at the branch level. We look at¨ methods for extracting efficiency measures for each function.

SB18.3 Efficiency vs. Effectiveness in Organizational Performance Hans Tuenter --- York Univ., Schulich Sch. of Bus., 4700 Keele St., North York, Ontario, M3J 1P3 , Canada (htuenter@bus.yorku.ca)

DEA has been used in many studies to evaluate bank branch¨ performance. We look at efficiency (at the DMU level) vs.¨ effectiveness (at a higher level in the hierarchy) in the¨ transformation of resources into outputs at the branch level.
