Property taxation as incentive for cost control: Empirical evidence for utility services in Norway

Recent theoretical research suggests that property taxation has incentive effects that can help control cost problems in the public sector. The institutional setting in Norway allows this first empirical investigation of the incentive effect of property taxation, since we can separate between local governments with and without property tax. The raw data of the variation in the unit cost level for utilities show that local governments with property tax have 20% lower unit cost. Using both linear regression and propensity score matching, we are not able to wash out the difference in unit costs. Our interpretation is that having a visible and controversial local tax related to property stimulates voter interest in local government activities and thereby may help cost control.
