免费提供预防性保健产品可以大大增加低收入国家的获得机会。免费提供的成本问题是，一些接受者可能不会使用该产品，浪费资源（过度包容）。然而，收取一定的费用来筛选非用户可能会筛选出穷人谁需要和将使用该产品（过度排斥）。我们报告一个随机对照试验的筛选机制，结合了免费提供的氯溶液的水处理与一个小的非货币成本（家庭券，需要按月赎回，以便）。相对于非凭证免费分配计划，这一机制将氯的采购量减少了60个百分点，但将储存水检测为氯残留阳性的家庭比例仅减少了1个百分点，大大改善了过度包容和过度排斥之间的权衡。
Free provision of preventive health products can dramatically increase access in low income countries. A cost concern about free provision is that some recipients may not use the product, wasting resources (over-inclusion). Yet charging a price to screen out non-users may screen out poor people who need and would use the product (over-exclusion). We report on a randomized controlled trial of a screening mechanism that combines the free provision of chlorine solution for water treatment with a small non-monetary cost (household vouchers that need to be redeemed monthly in order). Relative to a non-voucher free distribution program, this mechanism reduces the quantity of chlorine procured by 60 percentage points, but reduces the share of households whose stored water tests positive for chlorine residual by only one percentage point, dramatically improving the tradeoff between over-inclusion and over-exclusion.
