The literature examining the number of parties cross-nationally has focused extensively on the impact of electoral systems; the study of social cleavages is, by comparison, less well developed. While a sizeable body of research has examined the effects of ethnic and other measures of diversity, other cleavages have received less attention. This article focuses on the impact of socioeconomic development-reflecting class and urban-rural cleavages-on party system fragmentation. Examining a large cross-national dataset, the analysis shows that, in line with the expectations of social cleavage theory and independently of other social cleavage variables, socioeconomic development is associated with higher levels of party system fragmentation.

“…Natural experimental solutions have thus been proposed. Studies of this sort offer an exploration of plausibly exogenous variation in electoral rules and thereby seek to enhance the validity of causal claims relating to electoral systems effects (see Blais et al, 2011; Pellicer and Wegner, 2014; Singer, 2015). Our study aims to contribute to this stream of research.…”

We exploit a rare natural experiment, a recent reform of local elections in Poland, to study an extension of Duverger’s laws. We analyse party system fragmentation under single-member plurality rule vis-à-vis a proportional representation formula accompanied by a legal threshold. We demonstrate that the presence of a threshold alters Duverger’s ‘psychological’ effect. Proportional representation with a threshold tends to be on a par with single-member plurality as regards restricting the effective number of electoral parties, largely due to the absence of smaller groupings with spatially concentrated support. At the same time, Duverger’s ‘mechanical’ effect takes a rather standard form, single-member plurality being relatively powerful at constraining the effective number of legislative parties.

“…Fujiwara (2011) étudie les élections municipales au Brésil. À l'instar des élections locales marocaines étudiées par Pellicer et Wegner (2014), les élections municipales au Brésil ont des caractéristiques quasi expérimentales puisque les municipalités sous un certain seuil de population ont un mode de scrutin pluralitaire à un tour tandis que celles au-delà du seuil ont un scrutin à deux tours. L'auteur détermine qu'avec un système pluralitaire les électeurs votent davantage pour les deux principaux concurrents et moins pour le troisième candidat, ceci étant d'autant plus le cas lorsque les courses sont serrées.…”

“…Le problème d'endogénéité est quelque peu atténué par le fait que le système électoral est rarement changé et que les raisons pour lesquelles un quelconque système a été choisi il y a 100 ans pourraient avoir bien peu en commun avec la politique contemporaine. Pellicer et Wegner (2014) étudient les élections locales au Maroc en 2003 et 2009. Dans ces élections, les municipalités sous un certain seuil de population ont un système majoritaire alors que celles au-delà de ce seuil ont un scrutin proportionnel.…”
