Applicants are ranked randomly, and treatment offers are made following that ranking until all seats are filled. To estimate causal effects, researchers often compare applicants getting and not getting an offer. We show that those two groups are not statistically comparable. Therefore, the estimator arising from that comparison is inconsistent when the number of waitlists goes to infinity. We propose a new estimator, and show that it is consistent, provided the waitlists have at least two seats. Finally, we revisit an application, and we show that using our estimator can lead to a statistically significant difference with respect to the results obtained using the commonly used estimator.<\/jats:p>","DOI":"10.3982\/ecta16032","type":"journal-article","created":{"date-parts":[[2020,7,21]],"date-time":"2020-07-21T08:43:25Z","timestamp":1595321005000},"page":"1453-1477","source":"Crossref","is-referenced-by-count":28,"title":["Estimating the Effect of Treatments Allocated by Randomized Waiting Lists"],"prefix":"10.3982","volume":"88","author":[{"given":"Cl\u00e9ment","family":"Chaisemartin","sequence":"first","affiliation":[{"name":"Economics Department, University of California at Santa Barbara"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luc","family":"Behaghel","sequence":"additional","affiliation":[{"name":"Paris School of Economics, INRAE"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2359","published-online":{"date-parts":[[2020]]},"reference":[{"issue":"1","key":"ecta200164-bib-0001","doi-asserted-by":"crossref","first-page":"91","DOI":"10.1111\/1468-0262.00270","volume":"70","author":"Abadie","year":"2002","journal-title":"Econometrica"},{"key":"ecta200164-bib-0002","doi-asserted-by":"crossref","DOI":"10.2307\/j.ctvcm4j72","volume-title":"Mostly Harmless Econometrics: An Empiricist's Companion","author":"Angrist","year":"2008"},{"issue":"434","key":"ecta200164-bib-0003","doi-asserted-by":"crossref","first-page":"444","DOI":"10.1080\/01621459.1996.10476902","volume":"91","author":"Angrist","year":"1996","journal-title":"Journal of the American Statistical Association"},{"issue":"1","key":"ecta200164-bib-0004","first-page":"140","volume":"9","author":"Behaghel","year":"2017","journal-title":"American Economic Journal: Applied Economics"},{"key":"ecta200164-bib-0005","volume-title":"Probability and Measure","author":"Billingsley","year":"1986","edition":"Second"},{"issue":"1","key":"ecta200164-bib-0006","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1017\/S0003055415000520","volume":"110","author":"Blattman","year":"2016","journal-title":"American Political Science Review"},{"issue":"1","key":"ecta200164-bib-0007","first-page":"123","volume":"7","author":"Cr\u00e9pon","year":"2015","journal-title":"American Economic Journal: Applied Economics"},{"key":"ecta200164-bib-0008","doi-asserted-by":"crossref","unstructured":"de Chaisemartin, C., and L.
