Party system change in east Germany

This article is part of the special cluster titled Parties and Democratic Linkage in Post-Communist Europe, guest edited by Lori Thorlakson, and will be published in the August 2018 issue of EEPS This article introduces a special section on parties and democratic linkage in post-communist Europe. It sets out the main objectives and research questions that guide the four articles in this special section, presenting these in the context of the comparative politics literature on party and party system change and democratic development. It introduces the key arguments of the articles in the section, arguing that the contributions identify regionally distinctive patterns of party and party system behaviour in Central and Eastern Europe. These patterns have fuelled a quest for more suitable conceptual and measurement tools and call for diversity in comparative analysis, combining intra and inter regional comparison.

This is the third of three chapters on political party systems and structures of competition, and presents an overall review. In the first section, Approaches to the Classification of Party Systems: A Review it looks at the principal existing approaches to the classification of party systems, pointing to both their limits and possibilities when applied within comparative analysis. It then goes on in the second section, Party Systems and the Competition for Government, to underline the importance of understanding the structure of competition in any given party system, since in many ways the whole notion of a party system is centred on the assumption that there exists a stable structure of competition. Structures of competition can be seen to be either closed (and predictable) or open (and unpredictable), depending on the patterns of alternation in government, the degree of innovation or persistence in processes of government formation, and the range of parties gaining access to government. The emphasis in the third section, Party Systems and Electoral Outcomes, is on the need to distinguish between processes of electoral change on the one hand, and changes in party systems and the structures of competition on the other, a distinction which also allows the possibility of situations in which electoral change is the consequence rather than the cause of party system change.

Party systems represent parts of political systems which arise as a result of interactions between political parties. Party relations produce characteristics which place a particular party system within the typology of party systems. A number of factors can be considered in explaining the nature of party competition, most often placed within the categories of institutional and sociostructural factors. This paper analyses the impact of full and partial social cleavages on party systems. Given that the theory of social cleavages has proved insufficient in explaining party differences and the dynamics of party systems, especially in new democracies, we will improve the analysis by including the concept of partial social cleavages. This research shows the unequivocal influence of dominant social cleavages on the situation and changes in party systems. Although in some cases no changes in the type of party system have occurred, it can be concluded that exactly in those cases there exist permanent and ingrained social cleavages, but also partial cleavages which affect the relations in the party system at the given time. Identity issues stand out as the dominant topic in political competition, especially in the countries where ethnic relations have not been resolved.

Party systems, that is, the number and the size of all the parties within a country, can vary greatly across countries. I conduct a principal component analysis on a party seat share dataset of 17 advanced democracies from 1970 to 2013 to reduce the dimensionality of the data. I find that the most important dimensions that differentiate party systems are: “the size of the biggest two parties” and the level of “competition between the two biggest parties.” I use the results to compare the changes in electoral and legislative party systems. I also juxtapose the results to previous party system typologies and party system size measures. I find that typologies sort countries into categories based on variation along both dimensions. On the other hand, most of the current political science literature use measures (e.g., the effective number of parties) that are correlated with the first dimension. I suggest that instead of these, indices that measure the opposition structure and competition could be used to explore problems pertaining to the competitiveness of the party systems.

This article sets out to examine the extent of party system change in Scandinavia since the ‘earthquake elections’ in the early 1970s witnessed the parliamentary breakthrough of new parties and, in particular, the rise of a populist radical right. It deploys an analytical framework derived from Berglund and Lindström's five‐party Scandinavian model and an identification of the ‘core structures’ of the frozen party system in the region. In assessing party system change the significance of changes in the patterns of interaction between parties at the elite level, that is in the governmental and parliamentary arenas, is emphasised over and above electoral change. It is argued that the core features of the Scandinavian party systems have changed much less since 1970 than the structure of party competition and that the single most important development in the party politics of the region has been that the historic non‐socialist groupings have acquired increased ‘relevance’ as coalition parties both severally and collectively. The article concludes by asking: ‘so what?’ Can an indication of the extent of party system change be of assistance in understanding the wider workings of the political system and the operation of the legislative process?

In this article, I explore the nature of party systems that have emerged in Africa in the wake of the adoption of democratic political systems after 1990. Although political parties help shape core democratic processes and institutions, parties and party systems have received relatively scant attention in the scholarly literature on democratization in Africa. I argue that party systems in most African countries are built on quite a different foundation from the one that undergirds both advanced industrial democracies and the theories about party systems generated by their experiences. I assess the strengths and limitations of the comparative literature on party system development in the light of African experiences, and argue for a more critical examination of concepts from that literature that have been widely used to assess the prospects and progress of party system institutionalization, including pluralism, system fragmentation and volatility.

The article examines the peculiarities of the formation and development of multiparty system in the regions at the present stage of Russia’s political development. The article analyzes the processes of transformation of the Russian party system in the context of systematic changes in the mechanisms of legislative regulation of their party and political activities. The aim of the study is to determine the degree of influence of the regional party system on the exercise of political power in Russian regions. This is necessary to determine the main directions for improving the system of party legislation in the process of establishing a new political system. Conclusions. As a result of the conducted research, a number of unresolved contradictions in the formation and development of the modern Russian regional party system have been identified. These contradictions do not allow this type of party system to achieve the level of influence that would give them the opportunity to really and effectively participate in the current political process. It can be argued that the party systems that have developed today in the regions are lagging behind in their development in comparison with the all-Russian party system. The author concludes that in order to change the current situation, it is necessary to improve the quality of representation from political parties in regional and municipal authorities. In order for political parties in the regions to articulate the interests and needs of various social groups, they must have the necessary power resources in making decisions on the leadership and management of the region. One of such ways to increase the level of influence of the regional party system is, in the author’s opinion, the reform of party legislation in the direction of creating broader opportunities, both for creating parties of different political spectrum and for increasing their power capabilities.

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.

The article draws upon the formal coalition literature to demonstrate that party system change over the last thirty years means that the Volksparteien enjoy more coalition options and greater ideological leverage within coalitions that form than was the case in the past. The Free Democrats have lost their kingmaker status and the distribution of party weights over recent elections allows no other small party to act in this manner. By contrast, the numerical and ideological resources possessed by the two Volksparteien means that they remain the only parties within the German party system that can act as formateur in the coalition game and are less vulnerable to threats of a decisive defection by small parties to alternative coalitions than they were in the past.

The main goal of this article is to analyse the role of social, political and ideological factors in explaining party system change in Portugal during the democratic period (April 1974June 2005). We begin with the evolving trends in the party system format, and their main effects on the patterns of parties' interactions as well as on the functioning of the political system. This first approach will enable us to divide the democratic period into two distinct phases and an interlude. Following this, we will analyse the dimensions and strength of policy competition between the parties before, finally, analysing the impact of social, political and ideological factors on party system change in Portugal.

For a given electoral system, what average number and size distribution of parties can we expect? This book makes specific predictions that agree with world averages. The basic factors are assembly size and district magnitude (the number of seats allocated in the district). While previous models tell us only the direction in which to change the electoral system, the present ones also tell us by how much they must be changed so as to obtain the desired change in party system and cabinet duration. These are quantitatively predictive logical models. Combined with known particularities of a country, these models can be used for informed institutional design. Allocation of seats among countries in the European Parliament is also put on a logical basis.

Since 2020, the world has been officially battling a COVID-19 pandemic. Even countries with established crisis management plans and years of experience in handling political and economic crises, have been shaken. In the midst of the pandemic’s rampant effects, how politicians handle the crisis is of crucial importance to the preservation, development, and protection of nations in the future. Who is in power determines not only the stability, but the political course of countries. Hence, what happens to the party system as a result of an exogenous shock is a question we need to answer. Importantly, we have little evidence on how the handling of the COVID-19 pandemic affected party competition. Building on the party systems literature, we examine the effect of the pandemic on electoral volatility, party system size, and the number of new party contestants. We hypothesise that, in countries where the incumbent government handles the crisis less effectively, electoral volatility tends to be higher, party system size tends to be larger, and more new parties tend to enter the electoral race. Drawing on evidence from national parliamentary elections held by electoral democracies from March 2020 to April 2022, the empirical results support our hypothesis.

Issue Evolution in Political Science

This article considers party system effects and change in government-opposition dynamics in EU referendums. Relying on the analysis of party stances, party-voter alignments and campaign dynamics in 12 EU referendums in France, Ireland, Great-Britain and Spain, it shows that EU referendums tend to interfere with traditional party system dynamics in majoritarian democracies. By clearly manifesting a pro-European convergence between incumbent and mainstream opposition parties, they constitute a fertile ground to awake the ‘sleeping giant’ under certain conditions. EU referendums favor the temporary displacement of the partisan cleavage, create recurrent tensions for mainstream opposition parties and consistently reinforce the role played by protest parties. The recurrent intra-party factionalism or the limited mobilizations of pro-European opposition parties in referendum campaigns are thus not so linked with their ideologies or with endogenous factors, but are rather largely induced by their specific party system ‘situations’.

Considerable evidence suggests that social diversity increases the number of political parties. While a vast literature examines this relationship by measuring social diversity as ethnic fragmentation, the convenience of capturing the level of social heterogeneity by using alternative indicators has been traditionally overlooked. In this article, I offer new evidence that documents the impact of social diversity on party system size by proxying the former as the number of social classes. Using both objective class positions and subjective class identifications and employing two different datasets that cover democratic legislative elections around the world between 1981 and 2015, I find that the effective number of social classes has a positive effect on party system fragmentation when the average district magnitude in a democracy is high. Given the difficulty to test these effects in a cross-country environment net of unobserved heterogeneity, I examine the robustness of the findings in Spain between 2000 and 2016, an ideal case due to large differences in district magnitude and a changing party system. Overall, the results suggest that high levels of social diversity are likely to increase party system fragmentation when the electoral system is permissive enough.
