An internal solution to an optimal control problem involving conjunctive use of surface and groundwater may be inapplicable if water is not sufficiently fungible across space and time. We provide a more general solution and apply it to the problem of allocating a limited amount of water from the...

Privatizing water and wastewater systems is fundamentally different to services such as electricity due to the prevalence of externalities. This paper discusses possible methods of improving incentives without full privatization. The discussion provides a crude framework containing the...
