Since 2004, 15 local governments have contracted this service to Korean Water Resources Corporation (K-Water). This paper examines the effects of the two different institutional arrangements— direct public delivery versus contracting out to K-Water—on cost saving and productivity. To do so, it employs a hybrid cost function approach and uses panel data covering the nine years from 2000 to 2008 in local governments. Empirical findings show mixed evidence on the effects of the two institutional arrangements on cost savings and productivity gains. Water supply costs are significantly lower under contracting out than under direct public delivery. But local water supply systems achieve productivity gains in both institutions, and there are no significant differences in productivity gains between them. Local water supply systems need to further reduce average water supply costs through increasing their size and magnitude. Keywords: water supply services; contracting out; total factor productivity (TFP); economies of scale; factor substitutability.

Introduction Local service delivery mode and its efficiency have gained continuing attention among scholars and practitioners over several decades.
