First paragraph:

Causal inference on political competition requires systematic knowledge of the positions that political parties take in a political space. Much scholarly effort has been dedicated to the measurement of party positions by means of manifestos, roll-call data, voter placements and expert judgments. Expert surveys have some notable advantages. They allow researchers to obtain positions for a large number of parties irrespective of their size, parliamentary status, whether they have a manifesto or not, and independent from the electoral cycle (Benoit and Laver, 2006Hooghe et al., 2010Rohrschneider and Whitefield, 2009).

Last Paragraph:

This research note presents information about trends in party positioning and assesses the validity and reliability of the longest running data collection project compiling expert party placements in the European context. As more researchers use CHES data to examine party competition and political representation (e.g. Adams et al., 2012Bakker et al., 2012Jolly, 2007Karreth et al., 2013van de Wardt, 2012), establishing the validity and reliability of expert placements is of key importance. Our results suggest that CHES data display quite high levels of inter-expert reliability and considerable common structure with different measures. This is good news for scholars aiming to examine the positions of parties on a variety of ideological and policy dimensions in a longitudinal and cross-national perspective.
