The Model
To address efficiency measurement in the presence of by-products, we introduce the following “splitting” variables: ik : the proportion of input i x consumed by subunit k q i4 : the proportion of input i x consumed by sub-bundle q in subunit 4 q 4 : the proportion of product 4 y made using process q, where q=1,2,3 q 4 : the proportion of by-product 4 z made under process q, where q=1,2 We assume that these proportions are known only within limits: aik1 ik aik2 , k 1,2,3 ai41 i4 ai42 (3.2) q q q b41 4 b42 q q q g41 4 g42 The basic principle to be used here is to view the DMU as consisting of a set of separate business units, with the overall efficiency of the DMU being a convex combination of the efficiencies of those business units. We proceed in three steps: Step 1: Derive a split of inputs and outputs across the respective subunits and subbundles; Step 2: Using the resulting inputs and outputs arising from step 1, derive efficiency scores for the subunits and sub-bundles; Step 3: Combine, by way of a convex combination, the subunit and sub-bundle efficiency scores to arrive at the aggregate efficiency of the DMU. 11 Step 1: Splitting Inputs and Outputs across Subunits and Sub-bundles As described above, the intention is to view the aggregate efficiency of the DMU as a convex combination of the efficiency scores of the subunits and sub-bundles. That being the case, we begin by looking at the efficiency ratio for a subunit. Given the definition of the input to output bundles ( , ) k Rk I for the subunits (see (2.1)), we would define the ratio for ( , ) k Rk I as k i I k k kj i ik ij e u y v x 0 0 / (3.3) In the specific case under investigation, we note that there is only one product k y in each of the output bundles Rk ; the more general case of multiple products is not included here, but is straightforward.
