摘要翻译：
我开发工具来了解提供一份参与项目的报价的平均效果，给定的数据来自一个随机报价的实验。我考虑到这样一种复杂情况，即个体可能不遵守他们被分配的状态，即那些没有得到一个提议的人可能从实验之外得到一个提议，而且数据可能只提供关于个体之间收到一个提议的部分信息。为此，我提出了一个新的非参数选择模型，它提供了一个概念框架来定义一系列评估要约效果的参数，利用在要约接收上可用的部分信息，并考虑了一系列识别假设。我说明了如何使用一个计算程序来清楚地了解各种假设下的参数。利用这些工具，我分析了一个政策的影响，提供了一个政策，以参与学前教育项目的头部启动影响研究的数据。我发现这样的政策影响了大量接受录取的孩子，他们随后对考试成绩产生了积极的影响。这些影响主要来自那些没有任何学前班作为外部选择的儿童。进行成本效益分析，我发现与考试成绩相关的收益可以超过与接受报价相关的净成本。

英文摘要：
I develop tools to learn about the average effects of providing an offer to participate in a program given data from an experiment that randomizes offers. I allow for the complication that individuals may not comply with their assigned status in the sense that those who are not provided an offer may receive one from outside the experiment, and that the data may provide only partial information on the receipt of an offer across individuals. To do so, I propose a new nonparametric selection model with unobserved choice sets that provides a conceptual framework to define a range of parameters evaluating the effects of an offer, exploit the partial information available on offer receipt, and also consider an array of identifying assumptions. I illustrate how a computational procedure can be used to sharply learn about the parameters under the various assumptions. Using these tools, I analyze the effects of a policy that provides an offer to participate in the Head Start preschool program given data from the Head Start Impact Study. I find that such a policy affects a large number of children who take up the offer, and that they subsequently have positive effects on test scores. These effects primarily arise from children who do not have any preschool as an outside option. Performing a cost-benefit analysis, I find that the earning benefits associated with the test score gains can outweigh the net costs associated with the take up of the offer.
