This paper considers empirically whether preference-based (empirical) power indices differ significantly from their preference-free (theoretical) counterparts. Drawing on the to date most comprehensive sample of EU Council votes (1993-2011), we use item-response models to estimate the EU27...

In the present study I use spatial voting model to assess the importance of the left-right and immigration issue dimensions on electoral behavior in Denmark, Norway, and Sweden. My findings indicate that distances between parties and voters on both left-right and immigration dimensions do...

When aggregating individual preferences through the majority rule in an n-dimensional spatial voting model, the ‘worst-case’ scenario is a social choice configuration where no political equilibrium exists unless a super-majority rate as high as 1 — 1/(n+1) is adopted. In this...

This paper investigates whether preference-based (empirical) power indices differ significantly from their preference-free (theoretical) counterparts. Drawing on the most comprehensive sample of EU Council votes to date (1993–2011), we use item-response models to estimate the EU27 member...

This Paper analyses bargaining between the European Parliament (EP) and the Council of Ministers (CM) in the Conciliation Committee with the aim of evaluating both institutions' power in the European Union's codecision procedure. In contrast to other studies, which use power indices or simple...

This paper proposes a unified framework that integrates the traditional index-based approach and the competing non-cooperative approach to power analysis. It rests on a quantifiable notion of ex post power as the (counter-factual) sensitivity of the expected or observed outcome to individual...

We introduce endogenous political parties into the Hotelling-Downs voting framework to model the selection of candidates. First, activists choose which party to join, if at all. Second, party members select a champion for the general election. Third, the electorate median voter determines the...
