英文摘要：
Many real-life settings of consumer-choice involve social interactions, causing targeted policies to have spillover-effects. This paper develops novel empirical tools for analyzing demand and welfare-effects of policy-interventions in binary choice settings with social interactions. Examples include subsidies for health-product adoption and vouchers for attending a high-achieving school. We establish the connection between econometrics of large games and Brock-Durlauf-type interaction models, under both I.I.D. and spatially correlated unobservables. We develop new convergence results for associated beliefs and estimates of preference-parameters under increasing-domain spatial asymptotics. Next, we show that even with fully parametric specifications and unique equilibrium, choice data, that are sufficient for counterfactual demand-prediction under interactions, are insufficient for welfare-calculations. This is because distinct underlying mechanisms producing the same interaction coefficient can imply different welfare-effects and deadweight-loss from a policy-intervention. Standard index-restrictions imply distribution-free bounds on welfare. We illustrate our results using experimental data on mosquito-net adoption in rural Kenya.

中文摘要：
许多消费者选择的现实生活环境涉及社会互动，导致有针对性的政策产生溢出效应。本文开发了新的实证工具，用于分析具有社会互动的二元选择环境中政策干预的需求和福利效应。这方面的例子包括采用保健产品的补贴和上一所成绩优异的学校的优惠券。在I.I.D.和空间相关的不可观测项下，我们建立了大型博弈的计量经济学与Brock-Durlauf型相互作用模型之间的联系。在增加的域空间渐近条件下，我们给出了相关信念和偏好参数估计的新的收敛结果。接下来，我们表明，即使有全参数规范和唯一均衡，足以预测交互作用下反事实需求的选择数据也不足以计算福利。这是因为产生相同交互系数的不同潜在机制可能意味着政策干预的不同福利效应和无谓损失。标准指数限制意味着对福利的无分配限制。我们使用肯尼亚农村蚊帐使用的实验数据来说明我们的结果。
