Empirical Analyses of Committee VotingResearchers: Matias Iaryczower (Princeton), Matthew Shum (Caltech)Some of the most important decisions in societies are made in committees voting bodies with a small number of members). In the US, the Supreme Court, the House of Representatives, and municipal school boards are examples of committees who make decisions with far-reaching consequences for the public. The overarching goal of this proposal is to develop an empirical framework for understanding how committees "work": how the disparate preferences and know-how of its members are aggregated into a collective outcome in different institutional environments.To do this, we develop a new statistical and econometric model for analyzing decision-making in committees, in which members' actions depend not only on their preferences, but also on their information. This model is based on the theoretical literature of strategic voting with incomplete information, which has become the preferred approach to modeling committee voting in frontier research in political economy. Using data on the voting records of committee members in real-world committees, we estimate the model parameters, which correspond to the preferences (biases) as well as information of each committee member. Disentangling bias and quality of information in turn allows us to measure the value of information in the committee, to measure the effectiveness of committee decision-making, and to compute counterfactual simulations to assess how differently committee decisions would have been under alternative voting rules or committee compositions.This proposal contains four projects which illustrate the power of our analytical framework in several important real-world institutions. The first project focuses on decisions in the United States Supreme Court. In this context, we consider whether case-specific information have enough power to overturn the prior biases and ideological considerations of the justices. The second and third projects focus on decision-making in state supreme courts, and address questions regarding differences in bias and quality of information of appointed and elected justices (bureaucrats and politicians), and also the effects of campaign financing on elected judges' voting behavior. In the fourth project, we analyze voting in theUS congress during the founding fathers period (Congresses 1 to 17).Our work has important implications for the analysis of policy and effective design of voting institutions. Our empirical framework allows us to quantify (with minimal data requirements) the effectiveness of committee decision-making in different institutional settings. This in turn allows both an evaluation of real-world committees and, via counterfactual simulations, to assess whether alternative institutional arrangements (such as majority vs. unanimity rules, or limits on campaign contributions) could lead to better decisions. The computer code and data files generated by our research can be applied readily by other researchers to analyze committee voting in myriads of other settings.

委员会投票的经验分析研究人员：Matias Iaryczower(普林斯顿大学)，Matthew Shum(加州理工学院)社会中一些最重要的决定是由成员人数较少的委员会投票机构做出的)。在美国，最高法院、众议院和市政学校董事会是做出对公众产生深远影响的决定的委员会的例子。这项建议的总体目标是建立一个经验框架，以了解委员会如何“运作”：其成员的不同偏好和专门知识如何在不同的制度环境中聚合为集体结果。为此，我们开发了一个新的统计和计量经济学模型来分析委员会的决策，其中成员的行动不仅取决于他们的偏好，还取决于他们的信息。该模型以不完全信息下的战略投票理论文献为基础，已成为政治经济学前沿研究中模拟委员会投票的首选方法。利用真实委员会中委员会成员的投票记录数据，我们估计了与每个委员会成员的偏好(偏向)以及信息相对应的模型参数。分离偏见和信息质量反过来允许我们衡量委员会中信息的价值，衡量委员会决策的有效性，并计算反事实模拟，以评估委员会决策在替代投票规则或委员会组成下会有多大不同。本提案包含四个项目，这些项目说明了我们的分析框架在几个重要的现实世界机构中的力量。第一个项目侧重于美国最高法院的裁决。在这方面，我们考虑具体案件的信息是否有足够的力量推翻法官先前的偏见和意识形态考虑。第二个和第三个项目侧重于州最高法院的决策，并解决有关任命和当选法官(官僚和政客)在偏见和信息质量方面的差异，以及竞选资金对当选法官投票行为的影响的问题。在第四个项目中，我们分析了美国国会在开国元勋时期(国会1至17)的投票情况，我们的工作对政策分析和投票机构的有效设计具有重要的意义。我们的经验框架使我们能够量化(以最低限度的数据要求)委员会决策在不同机构设置中的有效性。这反过来又允许对现实世界的委员会进行评估，并通过反事实模拟来评估替代制度安排(如多数与一致规则，或对竞选捐款的限制)是否可以带来更好的决定。我们的研究产生的计算机代码和数据文件可以很容易地被其他研究人员应用于分析各种其他环境下的委员会投票。
