Do parties with different ideological origins adjust their policies in response to the binding commitments that derive from the European integration process? This paper examines whether party platforms have adapted to the ideological content of EU treaty provisions – based on ‘neoliberalism’ and ‘regulated capitalism’ – across a range of policy areas The analysis builds on existing research which has examined how party families respond to the challenges and opportunities of the integration process. This is the first study that focuses on long-term party policy adjustment across different policy areas by examining whether there has been a shift away from core ideological goals towards the direction of EU policy. The main finding is that there has generally been a shift towards the direction of EU policy across all party families in both member and non-member states. The findings have implications for the quality of representation and functioning of democracy in the member states since the deepening of the European integration process reduces ideologically distinct policy alternatives across party families and can hinder policy innovation

This study addresses the dynamics of the issue space in multiparty systems by examining to what extent, and under what conditions, parties respond to the issue ownership of other parties on the green issue. To understand why some issues become part and parcel of the political agenda in multiparty systems, it is crucial not only to examine the strategies of issue entrepreneurs, but also the responses of other parties. It is argued that the extent to which other parties respond to, rather than ignore, the issue mobilisation of green parties depends on two factors: how much of an electoral threat the green party poses to a specific party; and the extent to which the political and economic context makes the green issue a potential vote winner. To analyse the evolution of the green issue, a time-series cross-section analysis is conducted using data from the Comparative Manifestos Project for 19 West European countries from 1980–2010. The findings have important implications for understanding issue evolution in multiparty systems and how and why the dynamics of party competition on the green issue vary across time and space.

Segnalazione bibliografica. Acta Politica - Issue, 13/07/11 Autore: Daniel Bochsler Abstract Electoral rules have long been held as important for the success of new political parties, but research has neglected the dimension of territory in this equation. This article argues that the territorial structure of social groups, in interaction with the electoral system, makes a crucial difference for the ability of new parties to enter parliament. In district-based electoral systems, social groups that are highly concentrated face much lower hurdles with an own party than groups that are spread throughout the country. The argument is tested on a novel database on ethnic minority...

What sustains stability in legislative party systems between elections? This question commands attention given the potential for change highlighted in recent work on legislative party switching. In addressing the question, this article echoes a prominent theme in research on legislatures, parties, and party systems: the importance of the party label. The novelty here is the treatment of the individual legislator’s need for manifest loyalty to the status quo party label as the chief constraint that deters incumbents from switching and underpins stability in legislative party systems. Our theory focuses on the value of stable party affiliations to voters and thus to incumbents as well. We extract testable implications and assess hypotheses against an original cross-national dataset of over 4,300 monthly observations of MP behavior in 116 legislative terms. We find that the temporal proximity to elections deters MPs’ moves. This electoral deterrent acquires particular force under candidate-centered electoral systems

Multidimensional scaling (or MDS) is a methodology for producing geometric models of proximities data. Multidimensional scaling has a long history in political science research. However, most applications of MDS are purely descriptive, with no attempt to assess stability or sampling variability in the scaling solution. In this article, we develop a bootstrap resampling strategy for constructing confidence regions in multidimensional scaling solutions. The methodology is illustrated by performing an inferential multidimensional scaling analysis on data from the 2004 American National Election Study (ANES). The bootstrap procedure is very simple, and it is adaptable to a wide variety of MDS models. Our approach enhances the utility of multidimensional scaling as a tool for testing substantive theories while still retaining the flexibility in assumptions, model details, and estimation procedures that make MDS so useful for exploring structure in data.
