Segnalazione bibliografica. British Journal of Political Science (2011), 41: 341-361 Autore: Jay K. Dow   Abstract This study evaluates the extent of party-system extremism in thirty-one electoral democracies as a function of electoral-system proportionality. It uses data from the Comparative Studies of Electoral Systems project to estimate the extent of party-system compactness or dispersion across polities and to determine whether more proportional systems foster greater ideological divergence among parties. Electoral system characteristics most associated with party-system compactness in the ideological space are investigated. The empirics show that more proportional systems support greater ideological dispersion, while less proportional systems encourage parties to cluster nearer the centre of the electoral space. This...

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. European Journal of Political Research (May 2011), 50: 365–394 Autori: Mark Andreas Kayser, Christopher Wlezien Abstract Numerous studies have demonstrated a weakening identification of voters with political parties in Western Europe over the last three decades. It is argued here that the growing proportion of voters with weak or no party affinities has strong implications for economic voting. (mgtrailer.com) When the proportion of voters with partisan affinities is low, the effect of economic performance on election outcomes is strong; when partisans proliferate, economic conditions matter less. Employing Eurobarometer data for eight European countries from 1976 to 1992, this inverse association between...

Segnalazione bibliografica. American Political Science Review 01 August 2011 105: 631-641 Autore: Andrew Rehfeld Abstract In this reply to Jane Mansbridge's “Clarifying the Concept of Representation” in this issue (American Political Science Review 2011). I argue that our main disagreements are conceptual, and are traceable to the attempt to treat the concept of representation as a “single highly complex concept” as Hanna Pitkin once put it. Instead, I argue, it would be more useful to develop the various concepts that emphasize the underlying forms of representation. Against the view that empirical regularity should guide concept formation, I suggest that the failure to find...

Segnalazione bibliografica. West European Politics, Volume 34, Number 5, 1 September 2011 , pp. 1070-1091(22) Autore: Pontus Odmalm Abstract Why is `the immigration issue' rarely polemical for the Swedish mainstream when it divides parties across Europe? Several factors suggest fertile ground for conflict, yet parties hesitate to capitalise on anti-immigration cues. Based on interviews with Swedish MPs, the article discusses two interlinked issues. First, immigration crystallises conflicting ideological streams: market liberalism vs. value conservatism (for the centre-right) and international solidarity vs. welfare...
