Efficient Spatial Allocation of Irrigation Water
研究存在输水损失时，灌溉用水量随距离水源远近的变化规律，发现边际成本定价会导致中下游农民付更多钱却得到更少水，并用实证需求函数比较了不同融资方案。
Abstract In the presence of conveyance losses, the efficient quantity of water applied falls with distance from the water source, but the amount of water “sent” (including conveyance losses) actually increases with distance from the source, except toward the tail end of the irrigation system. This implies that if marginal cost pricing were implemented, farmers at the middle and lower reaches of the system would have to pay more money for less water received. The model is illustrated and alternative financing schemes compared for an empirically derived demand function for irrigation water.
