Segnalazione bibliografica. European Journal of Political Research, online version Autore: Markus Wagner Abstract Parties have an incentive to take up extreme positions in order to achieve policy differentiation and issue ownership, and it would make sense for a party to stress these positions as well. These incentives are not the same for all issues and all parties but may be modified by other strategic conditions: party size, party system size, positional distinctiveness and systemic salience. Using manifesto-based measures of salience and expert assessments of party positions, the findings in this article are that parties emphasise extreme positions if, first, they are relatively small...

Segnalazione bibliografica. American Political Science Review (2010), vol.104, n.4: 625-643 Autore: David Stasavage Abstract Scholars investigating European state development have long placed a heavy emphasis on the role played by representative institutions. The presence of an active representative assembly, it is argued, allowed citizens and rulers to contract over raising revenue and accessing credit. It may also have had implications for economic growth. These arguments have in turn been used to draw broad implications about the causal effect of analogous institutions in other places and during other time periods. But if assemblies had such clear efficiency benefits, why did they not become a universal phenomenon in Europe prior...

Segnalazione bibliografica. National Bureau of Economic Research (2009), working paper n. 15365 Autori: Alan S. Gerber, Gregory A. Huber, Ebonya Washington Abstract Political partisanship is strongly correlated with attitudes and behavior, but it is unclear from this pattern whether partisan identity has a causal effect on political behavior and attitudes. We report the results of a field experiment designed to investigate the causal effect of party identification. Prior to the February 2008 Connecticut presidential primary, researchers sent a mailing to a random sample of unaffiliated registered voters informing them of the need to register in order to participate in the upcoming primary. Comparing post-treatment survey...

Segnalazione bibliografica. British Journal of Political Science (2011), 41: 259-285 Autori: John Bartle, Sebastian Dellepiane-Avellaneda, James Stimson Abstract The political ‘centre’ is often discussed in debates about public policy and analyses of party strategies and election outcomes. Yet, to date, there has been little effort to estimate the political centre outside the United States. This article outlines a method of estimating the political centre using public opinion data collected for the period between 1950 and 2005. It is demonstrated that it is possible to measure the centre in Britain, that it moves over time, that it shifts in response to government activity...

Segnalazione bibliografica. British Journal of Political Science (2011), 41: 287-314 Autori: David Sanders, Harold D. Clarke, Marianne C. Stewart, Paul Whiteley Abstract A six-wave 2005–09 national panel survey conducted in conjunction with the British Election Study provided data for an investigation of sources of stability and change in voters’ party preferences. The authors test competing spatial and valence theories of party choice and investigate the hypothesis that spatial calculations provide cues for making valence judgements. Analyses reveal that valence mechanisms – heuristics based on party leader images, party performance evaluations and mutable partisan attachments – outperform a spatial model in terms of strength of direct effects on party choice....
