Voting patterns and alliance formation in the European Parliament.

Cohesion and Coalition Formation in the European Parliament: Roll-Call Votes and Twitter Activities

We study the cohesion within and the coalitions between political groups in the Eighth European Parliament (2014-2019) by analyzing two entirely different aspects of the behavior of the Members of the European Parliament (MEPs) in the policy-making processes. On one hand, we analyze their co-voting patterns and, on the other, their retweeting behavior. We make use of two diverse datasets in the...

Community detection in the European Parliament: A network approach

In this dissertation, we study networks of legislators, based on their voting behaviour. We describe different network-construction methods and we review the state of the art of how scholars transform voting data into networks describing the voting similarity of legislators. We describe how one can detect dense sets of nodes called “communities” and we discuss previous analyses of voting behavi...

Strategic Non-Voting in European Parliament Elections

Neural Network Analysis of Russian Parliament Voting Patterns

The recurrent neural network capable to provide the Boolean factor analysis of the binary data sets of high dimension and complexity is applied to discovery of voting patterns in the Russian parliament. The new method of sequential factor extraction based on the Lyapunov function is discussed in deep. Efficiency of the new method is shown on simulated data and on real data from Russian parliame...

Voting Weights and Formateur Advantages in the Formation of Coalition Governments

We examine the relationship between parliamentary seats and cabinet posts in European governments between 1946 and 2001. Our speci ̄cation improves on past studies in two respects. First, it derives and uses the voting weights of the underlying coalition formation games. This reduces the measurement error introduced when seat shares are used to proxy for voting weights. Second, the statistical m...
