Notes
The main problem in treating economies of scope revolves around access to data in which some firms (or plants) produce all the products of interest while other produce only subsets. See pp.263–269 in R. Färe, S. Grosskopf and C.A.K. Lovell (1994), Production Frontiers, (Cambridge, Cambridge University Press) and the references cited therein.

Semple (1996) “Sensitivity and Stability of Efficiency Classifications in DEA,” Journal of Productivity Analysis 7, pp.5–18.
The shape of this “ball” will depend on the norm that is used. For a discussion of these and other metric concepts and their associated geometric portrayals see A. Charnes and W.W. Cooper (1961), Management Models and Industrial Applications of Linear Programming (New York: John Wiley & Sons.)
This omission of DMU0 is also used in P. Andersen and N.C. Petersen (1993) “A Procedure for Ranking Efficient Units in DEA,” Management Science 39, pp.1261–1264. Their use is more closely associated with stability when a DMU is omitted, however, so we do not cover it here. See also R.M. Thrall (1996) “Duality Classification and Slacks in DEA,” Annals of Operations Research 66, pp.104–138.

In fact, Seiford and Zhu propose an iterative approach to assemble an exact stability region in L. Seiford and J. Zhu, “Stability Regions for Maintaining Efficiency in Data Envelopment Analysis,” European Journal of Operational Research 108, 1998, pp.127–139.

An alternate approach to simultaneous variations in all data has recently become available which is effected by the envelopment model. See L.M. Seiford and J. Zhu (1998) “Sensitivity Analysis of DEA Models for Simultaneous Changes in All Data,” Journal of the Operational Research Society 49, pp.1060–1071.
This status is easily recognized because θ * 1 =θ * 2 =θ * 3 =1 are all associated with uniquely obtained solutions with zero slacks. See A. Charnes, W.W. Cooper and R.M. Thrall (1991) “A Structure for Classifying and Characterizing Efficiency in Data Envelopment Analysis,” Journal of Productivity Analysis 2, pp.197–237.
