Autrice: Yanna Krupnikov American Journal of Political Science, Volume 55, Number 4, 1 October 2011 , pp. 797-813(17) Abstract Do negative campaign advertisements affect voter turnout? Existing literature on this topic has produced conflicting empirical results. Some scholars show that negativity is demobilizing. Others show that negativity is mobilizing. Still others show that negativity has no effect on turnout. Relying on the psychology of decision making, this research argues and shows that this empirical stalemate is due to the fact that existing work ignores a crucial...

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...

Two new studies challenge the prevailing consensus that proportional representation (PR) systems produce greater ideological congruence between governments and their citizens than majoritarian ones. This has led to what has become known as the ‘ideological congruence controversy’. G. Bingham Powell claims to resolve this controversy in favour of PR systems. Specifically, he argues that the results from the two new studies are based on an anomalous decade and that PR systems generally do produce greater government congruence. In addition, he also asserts that PR systems exhibit less variability in government congruence. In this article, the empirical evidence for these two claims is re-evaluated using exactly the same data as employed by Powell. The analysis indicates that although PR systems produce better and more consistent representation in the legislature, they do not hold an advantage when it comes to representation at the governmental level.
