The Effectiveness of a Water Right Retirement Program at Conserving Water
采用双重差分法评估堪萨斯州水权退出计划2008-2012年试点阶段对减少地下水或地表水使用的效果，发现该计划在重点区域显著减少了地下水使用，但对地表水无影响。
This study employs a difference-in-differences framework to assess the effectiveness of the 2008–2012 pilot phase of the Kansas Water Right Transition Assistance Program at reducing either groundwater or surface water use. We distinguish between two program components: creek subbasins and designated High Priority Areas. Results demonstrate that water right retirement in the High Priority Areas substantially reduced groundwater use. Regardless of the program component, we find no effect on surface water use. Our conclusions are robust to various specifications. This study is the first to directly estimate the effect of water right retirement or any form of restriction on irrigation-related water rights. <i></i>
