Despite the fact that the catch-all thesis has profoundly affected scholarship on political parties, operationalizing the thesis and applying it to evaluate empirical cases has proved challenging for scholars. The thesis has been criticized for lacking a theoretical framework of analysis and clear causal logic. Therefore, while it is often cited it is rarely tested. In this article I develop a …
With a focus on the Portuguese case, this article shows how MPs express disagreement with their parties in a highly cohesive and party-dominated parliament. We review the features that explain why the Portuguese institutional framework reinforces party control over the parliamentary mandate and discuss the different ways Portuguese MPs express party dissent. In the last section of the article, …
This article investigates the nature of party behaviour in the legislative arena in a developing democracy by undertaking a spatial analysis of voting in the Korean National Assembly. We discover the main dimensions of politics in the Korean parliament and look at how KNA members’ ideological preferences, regional interests and the shift from divided to unified government shapes relations betwe…
In this article, we compare the experiences of male and female party leaders at the provincial and federal levels in Canada between 1980 and 2005 and test several hypotheses regarding gender and party leadership. The Canadian case provides an excellent case study given the relatively large number of women (21 in total) who held the position of party leader during the time period in question. Th…
This article proposes a new model of government formation: the Dual Power Base Model. The starting point is the median voter theorem, but an institutional limitation suggested by Laver and Shepsle (2000) is added. The claim is that it takes a certain number of MPs to cope with the practical tasks of running a government — that is, to have ‘Office Capacity’. If the median party has Office Capaci…
In this article, we analyze the policy and office motivations of parties in coalition-formation processes at the German federal-state level. We utilize a model developed by Sened that considers both motivations simultaneously and introduces a method by which to estimate its key parameters using data of German state-level coalition-formations.
The purpose of this article is to further our understanding of the directional nature of left—right scores. I suggest that a party’s ability to modify its perceived position is conditional on whether parties adopt their manifestos to alter their perceived position and on whether voters are persuaded by parties’ attempts to relocate in political space. As voters’ knowledge of political parties i…
Katz and Mair’s provocative Cartel Party argument continues to create fertile ground for debate. This article contributes to under-explored areas of this debate by enhancing the theoretical and empirical understanding of the change in the relationship between parties and voters resulting from the introduction of the cartelizing condition of public funding. To this end, the article examines vote…
In this article, we investigate the effect of political parties on legislative behaviour. We compile and analyse a unique dataset of all roll-call votes for all the sessions of the Irish Free State Seanad (the Upper Chamber in the legislature, 1922—36). The development of legislative parties inside the Irish Seanad led to the formation of cohesive voting blocs after 1928. This caused dramatic s…
Do parties adjust their economic policy positions in response to the international economy? I explore how international economic conditions affect Western Europe’s welfare states by quantitatively analysing parties’ ideological dynamics over time. Considering the convergence—divergence argument of the globalization literature, I evaluate the hypothesis that economic openness motivates parties t…
An influential political science literature argues that integration of radical political parties within the political system leads to their moderation. These parties trade off their ideological platforms for electoral viability and political legality. Radicals become moderates through strategic interests. In this article, I revisit this thesis and apply it to the Islamic political actors in Ira…
The growing literature on personal vote assumes that candidates with strong local ties should be more successful electorally and more likely to break party unity in parliament. Using unique data from Estonia on candidates’ personal vote-earning attributes, such as local birthplace and local-level political experience, this research note offers the first direct test of both of these assumptions.…
Studies of the emergence and electoral success of new parties frequently suffer from conceptual and methodological flaws: effects of electoral institutions that primarily operate at the level of the constituencies are specified at the national level; central explanatory variables such as electoral demands and competitors’ responses are measured with crude proxies; the interplay of formation and…
The Laakso—Taagepera index of the effective number of parties, while satisfying most of the requirements of this aggregate quantity, tends to produce unrealistically high scores for party constellations in which the shares of the largest parties exceed 50 percent, and can produce misleading results in several other situations. After reviewing the structural properties of the Laakso—Taagepera in…
This article focuses on the participation of party members in intra-party elections and on explanations for this behaviour. The number of intra-party elections is increasing, but their study remains an under-researched phenomenon in contemporary party politics. I test whether participation theories applicable to participation in society also obtain in intra-party elections. The theories tested …
This study joins two existing logical models and tests the resulting predictions of mean cabinet duration (C). One of these models predicts C based on effective number of parties (N): C = k/N2, where k is found to be around 42 years. The other predicts N on the basis of number of seats in the assembly (S) and district magnitude (M). The new combined model leads to a prediction for the mean cab…
In the digital age it is claimed that political parties do not have the capacity to deliver the advanced technical services that modern campaigning demands, and that much of the campaign work is better handled by political consultants. Based on the ‘hybridization’ view of campaign change, the article explores to what extent ICTs increase the need for campaign professionals, and what type of pro…
In this article, I examine the roll-call voting behaviour of U.S. Senate Majority Leaders, finding that Leaders generally locate around the ideological mean and median of their party at selection and at the beginning of their tenure but move toward the partisan extreme as their leadership progresses. Statistical analysis links this movement to size of majority; that is, as their partisan majori…
Expert surveys have become increasingly popular among political scientists. One of the problems of using surveys (of any sort) to estimate party positions is that respondents can be influenced by their subjective political views. As a consequence, experts may give biased responses, and such (ideological) bias may affect certain parties more than others. In this paper, we use the latest expert s…
The literature on Western European parliaments has long pointed to an increase in non-legislative activities, including questions to the minister and interpellations; however, it has struggled to explain this development. This paper argues that the explanation ought to be sought in the increased importance of issue competition among political parties in Western Europe. Political parties are inc…
