Party system volatility, regeneration and de-institutionalization in Western Europe (1945–2015)

Despite a great flourishing of studies about Latin America and Central and Eastern Europe, the issue of party system institutionalization has been widely neglected in Western Europe, where the presence of stable and predictable patterns of interactions among political actors has been generally taken for granted for a long time. Nevertheless, party system institutionalization is not something that can be gained once and for all. This article proposes a theoretical reconceptualization and a new empirical operationalization of party system (de-)institutionalization. Furthermore, it tests the presence of patterns of de-institutionalization in Western Europe from 1945 to (March) 2015 (336 elections in 19 countries) by using an original database of electoral volatility and of its internal components (regeneration and alteration). Data analysis shows that Western Europe is facing great electoral instability and party system regeneration and that many countries have experienced sequences of party system de-institutionalization, especially in the last two decades.

A growing impact of new parties: myth or reality? Party system innovation in Western Europe after 1945

Despite the large body of literature on the emergence and success of new political parties in Western Europe, few, if any, attention has been paid to investigate new parties from a systemic perspective, therefore exploring their potential effects on party systems. This article focuses on party system innovation (PSInn), defined as the aggregate level of ‘newness’ recorded in a party system at a given election. After having reviewed the extant literature on the topic, the article discusses what a new party is and provides a new index to measure PSInn. The article analyses the evolution of PSInn across 324 elections held in 19 West European countries from 1945 to 2015 and its cumulative effects over time. Although in most countries the party landscape today is still very similar to the one appearing after World War II, data offer clear evidence of a sharp increase of innovation in the last few years.

Vote (de-)nationalisation and party system change in Italy (1948–2013)

The nationalisation of politics is a major political phenomenon deriving from the historical trend towards the formation of national electorates and party systems brought about by the progressive reduction in the significance of territorial cleavages. During the last 50 years, though the issue of vote nationalisation has been addressed by a large volume of literature, serious analysis of the Italian case has never made much progress, having been limited to the reflections of a few isolated authors. Over the past 20 years, a period marking the passage from the long period of polarised pluralism to the so-called ‘Second Republic’, the Italian party system has undergone profound changes, with the continuing emergence and growth of new political parties and a sharp increase in the levels of party fragmentation and volatility. How has nationalisation of the vote evolved in this changing framework? This article analyses the process of (de)-nationalisation of the vote in Italy and explains its evolution between the first (1948–1992) and the second (1994–2013) phases of the republican era, assessing the impact of various possible determinants. The empirical analysis shows that vote nationalisation in Italy is strongly associated with competition factors and with the level of institutionalisation of the party system.

Populist Success in a Hung Parliament: The 2018 General Election in Italy

ABSTRACT The 2018 Italian general elections were a crucial test to assess the resilience of mainstream parties vis-à-vis the challenge provided by populist forces and the stabilisation of the tripolar party system emerged in 2013. The article analyses the outcome of the election, whose most remarkable result was the unprecedented success of two populist parties, the M5S and the Lega, by focusing on key aspects such as the new electoral system, the coalition-building process, the electoral campaign, the evolution of the Italian party system, and the analysis of vote shifts between parties.
