Replication Data for: Field Evidence of the Effects of Pro-sociality and Transparency on COVID-19 App Attractiveness

These data and associated R analysis file are associated with the paper: \"Field Evidence of the Effects of Pro-sociality and Transparency on COVID-19 App Attractiveness\" We ran 14 separate Google display ad campaigns from February 1 to 26. These were the only Google Display ads run for CovidDefense. Each campaign was targeted at people who reside in Louisiana via IP address. All campaigns used the same settings, ad destination, and ad image from the state of Louisiana's CovidDefense marketing materials. The 14 ads varied only in their text data in alignment with the 14 conditions summarized in this file (ads.csv). There are two primary datasets: one (data_demo.csv) which has all 7,010,271 impressions and demographic data, and another (data_geo.csv) with just the impressions that have associated geographic information. The former includes columns for Google-estimated demographics like Age and Gender, with many impressions having values of ``Unknown''. These two data tables for demographic and geographic impressions were represented by a row for each impression with columns for whether that impression resulted in a click; the age and gender or geography of the impression; as well as indicator variables for the presence or absence of ad information (appeals, privacy transparency -- broad privacy reassurance, non-technical control, and technical control -- and data transparency). An associated R file is included which includes functions to reproduce each model and associated statistics.

本数据集及配套R分析文件与论文《亲社会性与透明度对新冠疫情应用吸引力的现场实证》（Field Evidence of the Effects of Pro-sociality and Transparency on COVID-19 App Attractiveness）相关。
研究团队于2月1日至26日期间开展了14组独立的谷歌展示广告（Google Display Ads）投放活动，该系列广告是CovidDefense项目唯一投放的谷歌展示广告。所有广告均通过IP地址定向至路易斯安那州常住居民，且采用统一的投放设置、广告落地页及广告图像，相关素材源自路易斯安那州官方CovidDefense营销物料。
14组广告仅在文本内容上存在差异，与本文件（ads.csv）中总结的14种实验条件完全匹配。
本数据集包含两类核心文件：其一为data_demo.csv，涵盖全部7,010,271次广告展示量（impressions）及人口统计学数据；其二为data_geo.csv，仅收录带有配套地理信息的广告展示量数据。
前者包含谷歌（Google）估算的年龄、性别等人口统计学特征字段，其中大量广告展示的对应字段取值为“未知（Unknown）”。
两类数据表（人口统计学展示量数据表与地理信息展示量数据表）均以单次广告展示为一行，列项包括该展示是否产生点击、该展示对应的年龄与性别信息或地理信息，以及用于标识各类广告信息是否存在的指示变量：包括诉求类信息、隐私透明度（宽泛隐私安抚、非技术管控、技术管控）及数据透明度。
配套的R分析文件包含可复现所有模型及对应统计量的函数代码。
