Supplementary Material for “Estimating Party Positions” on OSF/SocArXiv

I have just made available the supplementary material for Ruedin, Didier, and Laura Morales. 2017. “Estimating Party Positions on Immigration: Assessing the Reliability and Validity of Different Methods.” Party Politics available on OSF/SocArXiv. The supplement is also available at the publisher’s website, together with the article. In the paper, we systematically assess various methods to identify the position political parties take on immigration. In another paper about to be published by Party Politics, Christoffer Green-Pedersen and Simon Otjes demonstrate that immigration really has become more salient over time. All the more important it is to place parties on this issue, and our extensive evaluation finds high consistency between expert surveys, manual sentence-by-sentence coding and manual ‘checklist’ coding. On the other hand, there are inconsistent results with the CMP/MARPOR, Wordscores, Wordfish, and a dictionary approach using keywords.
