We identify the indirect effect, which operates through a mediator (i.e. intermediate variable) that is situated on the causal path between the treatment and the outcome, as well as the unmediated direct effect of the treatment by using distinct instruments for the endogenous treatment and the endogenous mediator. We examine various settings to obtain non-parametric identification of (natural) direct and indirect as well as controlled direct effects for continuous and discrete mediators and continuous and discrete instruments. We also provide a simulation study and two empirical illustrations.<\/jats:p>","DOI":"10.1111\/rssb.12232","type":"journal-article","created":{"date-parts":[[2017,5,4]],"date-time":"2017-05-04T08:56:46Z","timestamp":1493888206000},"page":"1645-1666","source":"Crossref","is-referenced-by-count":87,"title":["Direct and Indirect Treatment Effects\u2013Causal Chains and Mediation Analysis with Instrumental Variables"],"prefix":"10.1093","volume":"79","author":[{"given":"Markus","family":"Fr\u00f6lich","sequence":"first","affiliation":[{"name":"Center for Evaluation and Development , Mannheim"},{"name":"University of Mannheim , Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Huber","sequence":"additional","affiliation":[{"name":"University of Fribourg , Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2017,5,4]]},"reference":[{"key":"2023022002195293100_rssb12232-cit-0001","doi-asserted-by":"crossref","first-page":"1282","DOI":"10.1002\/sim.3016","article-title":"Mediation analysis via potential outcomes models","volume":"27","author":"Albert","year":"2008","journal-title":"Statist.
