Latest Working Papers

Simon Hix, Rafael Hortala-Vallve and Guillem Raimbau, The Effects of District Magnitude on Voting Behaviour (8 September 2014).  Is there more sincere voting in multi-member districts than in single-member districts? We seek to answer this question using a lab experiment, where we vary district magnitude while keeping voters' preferences and parties' positions constant.  We find that voting for the preferred party (sincere voting) increases with district magnitude. We also find, though, a high incidence of voting for the "frontrunner" in all of our elections, even when there are no incentives for doing so.   

Simon Hix, Abdul Noury and Gerard Roland, Is there a Strategic Selection Bias in Roll Call Votes in the European Parliament (version 22 July 2014).  This paper looks at the magnitude and significance of "selection bias" in roll call votes . Prior to 2009, all roll call votes (RCVs) in the European Parliament had to be requested by political groups. Since 2009, an RCV has been required in all final legislative votes. We exploit this rule change and compare differences between final legislative votes and other votes before and after the change, using a difference-in-differences approach. Using data from the first 18 months of EP6 (2004-09) and EP7 (2009-14), we failed to find ANY significant difference in the level of voting cohesion for the main political groups. These results suggest selection biases in RCVs due to strategic choices are at best negligible.

Bjørn Høyland, Sara Hobolt and Simon Hix, Career Ambitions and Legislative Participation: The Moderating Effect of Electoral Institutions (7 May 2014).  This paper looks at how electoral rules shape the career ambitions and paths of Members of the European Parliament (MEPs).  We analyze a unique dataset of both ‘stated’ and ‘realized’ career ambitions of MEPs, and find that MEPs who seek to move from the European to the national level participate less in legislative activities in the European Parliament than MEPs who plan to stay at the European level.  Also, legislators who want to continue in the EP participate more if they originate from party-centered (closed-list) than candidate-centered (open-list) electoral systems.  And, for MEPs who aim to move to the national level, participation in the EP is substantively lower amongst legislators from candidate-centered systems.  These results suggest that the responsiveness associated with open-lists comes at the expense of legislative activity.
