Segnalazione bibliografica. European Journal of Political Research, 20/07/2011 Autore: Joaquìn Artés Abstract The extent of strategic voting in the Spanish general elections of 2000, 2004 and 2008 is estimated using a new measure of strategic incentives suitable for proportional representation systems that avoids some of the problems associated with lagged variables. Strategic behaviour increased from 12 to 33 per cent of the electoral base of the United Left Party, the major victim of strategic defection. This estimate is a conservative one as elite mobilisation is controlled for in the constituencies, which is unusual in the literature on strategic voting that uses regression-based methods. Full...

Segnalazione bibliografica. Autori: Paolo Bellucci, Oliver Heath British Journal of Political Science January 2012 42 : pp 107-135 Abstract No consensus exists on the causal mechanisms underpinning declining voting based on social cleavages – religion and class – in Europe. Previous research has emphasized two main factors: social change within the electorate (bottom-up) and parties’ policy polarization (top-down). This article presents a third level of analysis that links parties and cleavage-related social organizations, producing a factor capable of reinforcing group identity and interest representation. This hypothesis was tested for Italy in 1968–2008, where changes in the party system provided a natural experiment to...

Segnalazione bibliografica. Autori: Richard S. Katz, Peter Mair Party Politics January 2012 vol. 18 no. 1 107-111 Abstract A recurring problem in comparative politics is determining the extent to which models derived in one setting can be transferred directly to other settings. The original cartel party thesis was meant to account for developments that were beginning to be observed in the established democracies of western Europe in the 1990s. Many of the contemporary conditions that appeared to be driving those developments are to be found in other places, but of course preceded by quite different historical trajectories. The articles on parties and interest...

A wide range of studies find that democracies experience more terrorism than non-democracies. However, surprisingly little terrorism research takes into account the variation among democracies in terms of their electoral institutions. Furthermore, despite much discussion of the differences in terrorist groups’ goals in the literature, little quantitative work distinguishes among groups with different goals, and none explores whether and how the influence of electoral institutions varies among groups with different goals. The argument in this article posits that electoral institutions influence the emergence of within-system groups, which seek policy changes, but do not influence the emergence of anti-system groups, which seek a complete overthrow of the existing regime and government. The study finds that within-system groups are significantly less likely to emerge in democracies that have a proportional representation system and higher levels of district magnitude, while neither of these factors affects the emergence of anti-system groups.
