Abstract
This article examines the conditions under which the European Parliament (EP) effectively exercises its informal agenda setting powers to directly influence the content of the European Union’s policy agenda through the use of ‘own initiative reports’ or EPOIR. We test three models of EPOIR influence (salience, linkage and ideology) utilizing a newly created dataset of all substantive references to EPOIR within Commission pre‐legislative communications and legislative proposals produced between 2000 and 2017. These references serve as the dependent variable in our analysis, which seeks to identify the traits of EPOIR that increase their likelihood of exerting agenda influence. Our findings suggest not only that EPOIR can and do help to shape the EU policy agenda, but that salience and inter‐institutional linkage are the most effective attributes in explaining when this type of EP agenda setting effort via EPOIR is most likely to be successful.
