Advances in Field Experiments, RIDGE, IIPF, Journees LAGV, and NOVAFRICA. This project was reviewed and approved in advance by the Institutional Review Board at The University of Texas at Dallas. The field experiment was pre-registered in the AEA RCT Registry (#0007483). To prevent contamination of the subject pool (e.g., that subjects could read about the hypotheses being tested), we posted the RCT pre-registration immediately after the deadline to file a protest had passed, but before conducting any analysis of the data. After the study is accepted for publication, we will share all the code and data through a public repository. Xinmei Yang and Miriam Malament provided superb research assistance.
