摘要翻译：
提供补贴商品的政策的成本效益往往因所提供商品的有限使用而受到损害。通过一项随机试验，我们测试了两种提高中国农村近视儿童免费眼镜项目成本效益的方法。要求接受者经受一场磨难，更好地针对使用眼镜的人，而不减少相对于免费送货的使用量。当免费提供眼镜但不受折磨时，信息运动增加了眼镜的使用。免费送货加信息被确定为最具社会成本效益的方法，并获得了最高的眼镜使用率。

英文摘要：
The cost-effectiveness of policies providing subsidized goods is often compromised by limited use of the goods provided. Through a randomized trial, we test two approaches to improve the cost-effectiveness of a program distributing free eyeglasses to myopic children in rural China. Requiring recipients to undergo an ordeal better targeted eyeglasses to those who used them without reducing usage relative to free delivery. An information campaign increased use when eyeglasses were freely delivered but not under an ordeal. Free delivery plus information was determined to be the most socially cost-effective approach and obtained the highest rate of eyeglass use.
