Measuring and Comparing Party Ideology and Heterogeneity

Estimates of party ideological positions in Western Democracies yield useful party-level information, but lack the ability to provide insight into intraparty politics. In this paper, we generate comparable measures of latent individual policy positions from elite survey data which enable analysis of elite-level party ideology and heterogeneity. This approach has advantages over both expert surveys and approaches based on behavioral data, such as roll call voting and is directly relevant to the study of party cohesion. We generate a measure of elite positions for several European countries using a common space scaling approach and demonstrate its validity as a measure of party ideology. We then apply these data to determine the sources of party heterogeneity, focusing on the role of intraparty competition in electoral systems, nomination rules, and party goals. We find that policy-seeking parties and centralized party nomination rules reduce party heterogeneity. While intraparty competition has no effect, the presence of these electoral rules conditions the effect of district magnitude

Public Preferences for Parliamentary Representation in the UK: An Overlooked Link?

Representation, both as a normative concept and a political process, has generated a rich literature across several national contexts. To develop our understanding of representational systems, scholars tend to assess the degree of policy congruence between parliamentarians and constituents as well as the role orientations adopted by elected parliamentarians and legislators. This paper contends that in order to have a complete understanding of representational systems, we must consider not only the representational roles adopted by parliamentarians, but also the publics' preferences regarding parliamentary representation. Specifically, I posit that individuals have attitudes about the type and degree of relationship that they believe should exist between elected parliamentarians, parties and constituents. Using data from a 2003 survey of the British public, I test the related hypotheses that individuals have meaningful and predictable preferences for the representational relationship they share with their members of parliament (MPs) and that these representational preferences in turn influence how individuals evaluate MPs. Finding support for both hypotheses, I argue that developing an understanding of normative public preferences for political representation is an important and overlooked component in advancing models of public support of both elected officials and governing institutions

Bills from the floor: why governing party groups initiate their own legislation

In parliamentary systems, why do party groups of the government camp initiate their own bills instead of going through the cabinet? This article suggests that such governing party group bills occur for three reasons: (a) cabinets hand out bills to the parties on the floor; (b) party groups or MPs want to signal to constituencies; or (c) parties on the floor are dissatisfied with cabinet policy making. Arguing that the absolute and relative importance of these explanations varies with institutional context, country-specific hypotheses with regard to the number of governing party group bills in Germany are tested. As expected, mechanisms (a) and (c) are especially important in explaining the occurrence of governing party group legislation in Germany
