Abstract: | The behavior of privately owned and publicly owned water utilities is examined by calculating the percentage difference between the observed cost and the optimum cost consistent with the Weak Axiom of Cost Minimization for each individual water utility. It allows for a comprehensive analysis of nearly optimizing behavior of economic units as opposed to the conventional analysis of exact optimizing behavior. The empirical results provide evidence that private water utilities are more efficient than public water utilities. |
