• The Credibility of Party Policy Rhetoric. Survey-experimental Evidence. Journal of Politics. Forthcoming. [pdf]

This paper analyzes how a party’s policy statements affect voters’ perceptions of where the party stands on a given issue. I argue that voters do not take a party’s statements at face value because these messages can be a strategic tool to win elections. I have tested this argument with a survey experiment fielded in the United Kingdom that exposes respondents to Conservative and Labour Party statements on immigration and the National Health Service. I report evidence that popular statements tend to have a weaker effect on voter perceptions than unpopular ones. This finding suggests a paradox: the more a party needs to change its reputation in order to gain votes, the stronger the voters’ skepticism.

  • Voter Discounting of Party Campaign Manifestos. An Analysis of Mainstream and Niche Parties in Western Europe, 1971-2011. Party Politics. Forthcoming. [accepted version]

This paper analyzes the conditions in which voters believe party platforms. I argue that voters find platforms that can help the party obtain more votes to be less informative about the party’s ideology. This hypothesis is tested with both mainstream and niche parties in Western Europe. I show that for mainstream parties, which have vote-seeking incentives to appear ideologically moderate, voters discount centrist manifestos. With respect to niche parties, which tend to lose support if they moderate, voters discount extreme platforms. These findings have implications for democratic representation, party competition and electoral volatility.

  • The Information Consequences of Party Leader Changes for Voter Perceptions of Party Positions. British Journal of Political Science. Forthcoming. Co-authored with Zeynep Somer-Topcu. [ pdf ] [replication materials]

This paper claims that leader changes open a window of opportunity for parties to shape their policy reputation. We argue that the appointment of a new leader increases the credibility of party policy messages. As a result, voters are more willing to listen to party rhetoric and therefore develop perceptions about the party’s ideological position that are more in line with the party’s discourse. We provide empirical evidence based on mainstream parties in Western Europe between 1979 and 2012. 

  • Rooting Out Corruption or Rooting for Corruption? The Heterogeneous Electoral Consequences of ScandalsPolitical Science Research and Methods 4 (2): 379-397. 2016. With Pablo Barberá and Gonzalo Rivero. [journal pdf] [pre-print accepted version]

This paper addresses the question of why, even in consolidated democracies, corrupt incumbents are frequently re-elected by their constituents. While the literature tends to attribute tolerance for corruption to a lack of credible information about incumbent wrongdoing or to generalized voter cynicism, we highlight how voter responses depend on the economic externalities of corruption.

  • And Yet It Moves: The Effect of Election Manifestos on Party Policy ImagesComparative Political Studies 47 (14): 1919-1944. 2014. [pdf] [Online Appendix]

Election campaigns are normatively expected to provide political parties with the opportunity to publicize their views on policy issues. This article analyzes whether the content of parties’ campaign manifestos actually influences voter perceptions of where parties stand ideologically. Focusing on Western European parties between 1971 and 2010, I show that the content of parties’ policy rhetoric does affect voter expectations. This paper thus offers a more reassuring conclusion about mass-elite linkages than previous studies.

  • Projection Bias in the Survey Placement of Spanish Political Parties: Differences between National and Regional Parties. Special issue in South European Society and Politics 17 (3):519-531. 2012. With Elias Dinas. [pdf]. Reprinted in Sanchez-Cuenca and Dinas (eds). 2013. Voters and Parties in the Spanish Political Space. Routledge.[link]

This paper examines ex-post rationalization in how survey respondents place political parties on issue scales. Comparing Spanish national and regional parties, we uncover how differences in the structure of political competition across party system shapes the intensity of rationalization in survey-based measures of party positions.
