Needs and Targeting
研究在资源有限时，如何在不同群体间分配扶贫资金以最小化贫困指数，发现最优分配可能与需求成反比，并讨论了两种扶贫策略下的条件。
This paper shows that when--in the manner of the recent targeting literature--the resources available for poverty relief are allocated across heterogeneous groups so as to minimize a well-behaved index of aggregate poverty, the optimal response to an increase in the needs of some group may be to reduce the resources allocated to it. Necessary and sufficient conditions for optimally-targeted benefits to be inversely related to needs are established under two polar forms of poverty alleviation strategy (pure contingency and strict means-testing) and the wider methodological implications of this possibility discussed.
