We show that, with a binary Imbens\u2013Angrist instrumental variable model and the monotone treatment response assumption, it is possible to identify the joint distribution of potential outcomes among compliers. This is necessary to identify the percentage of mobilized voters and their statistical characteristic defined by the moments of the joint distribution of treatment and covariates. Specifically, we develop a method that enables researchers to identify the statistical characteristic of persuasion types: always-voters, never-voters, and mobilized voters among compliers. These findings extend Abadie\u2019s kappa theorem. We also provide a sharp test for the two sets of identification assumptions. The test boils down to testing whether there exists a non-negative solution to a possibly underdetermined system of linear equations\u00a0with known coefficients. We apply these results to a voter mobilization experiment.<\/jats:p>","DOI":"10.1093\/ectj\/utaf003","type":"journal-article","created":{"date-parts":[[2025,1,10]],"date-time":"2025-01-10T22:27:01Z","timestamp":1736548021000},"page":"462-481","source":"Crossref","is-referenced-by-count":1,"title":["A binary IV model for persuasion: profiling persuasion types among compliers"],"prefix":"10.1093","volume":"28","author":[{"given":"Zeyang","family":"Yu","sequence":"first","affiliation":[{"name":"Princeton University Department of Politics, , Princeton, NJ 08544 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,1,10]]},"reference":[{"issue":"2","key":"2025092213285731100_bib1","doi-asserted-by":"crossref","first-page":"231","DOI":"10.1016\/S0304-4076(02)00201-4","article-title":"Semiparametric instrumental variable estimation of treatment response models","volume":"113","author":"Abadie","year":"2003","journal-title":"Journal of Econometrics"},{"issue":"2","key":"2025092213285731100_bib2","doi-asserted-by":"crossref","first-page":"412","DOI":"10.1017\/S0022381611000028","article-title":"Election timing and the electoral influence of interest groups","volume":"73","author":"Anzia","year":"2011","journal-title":"Journal of Politics"},{"key":"2025092213285731100_bib3","article-title":"On testing systems of linear inequalities with known coefficients","author":"Bai","year":"2022"},{"issue":"439","key":"2025092213285731100_bib4","doi-asserted-by":"crossref","first-page":"1171","DOI":"10.1080\/01621459.1997.10474074","article-title":"Bounds on treatment effects from studies with imperfect compliance","volume":"92","author":"Balke","year":"1997","journal-title":"Journal of the American Statistical Association"},{"issue":"1","key":"2025092213285731100_bib5","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1017\/S0003055415000520","article-title":"Can employment reduce lawlessness and rebellion?
