Vitaliano on Estimation of the Return on Capital in Municipal Water Systems

Donald F. Vitaliano (Rensselaer Polytechnic Institute, Department of Economics) has published Estimation of the Return on Capital in Municipal Water Systems, 58 Nat'l Tax J. 685 (Dec. 2005).  Here is the abstract:

Seventy–five small, municipal water systems are analyzed to determine if they employ the least–cost long–run capital stock, and if they minimize cost given the observed level of capital. The social cost of capital exceeds the estimated return on investment by more than four times, and actual production costs are 36 percent above minimum costs. Median capital stock inefficiency, due to overinvestment, is $70,500 per system, and median cost inefficiency is $24,300. Extrapolated to the seven thousand similar systems nationwide, the combined cost of these two types of inefficiency is $663.6 million per year.
