Abstract
This study empirically examines cost reductions in the Japanese sewerage industry through mergers by modeling the costs of sewage disposal. The cost model is speci ed in a translog form, and treats capital as aquasi- xed input. Employing the parameters estimated by the model, the long-run cost function is derived, which indicates that most sewerage operators should be merged to attain scale advantages. Furthermore, while the cost reductions through actual sewerage mergers are estimated to be 37.9 billion yen, a counterfactual simulation shows that a more far-reaching consolidation could achieve cost savings through scale advantages amounting to 190 billion yen.
