Abstract The comparative study of intraparty divisions and their determinants has been a long-debated matter, but some issues remain unresolved. First, the problem of the empirical identification of intraparty groups. Second, the lack of comparative perspective and large-N cross-country and cross-time analyses, given intraparty divisions...

  Introduction The Netherlands and the United Kingdom were the first member states to hold European elections on Thursday 23 May 2019 ahead of other European Union (EU) member states which followed on 24 May or later. One may have expected that the Netherlands and the UK would set a ‘Eurosceptic’ cast over the EP elections to be held in the remaining 26 EU member states but this was not the case for the Netherlands. Actually, quite the opposite happened. The big winner was the pro-EU Labour Party (PvdA) which won the largest vote share of 18.9 per cent, up 9.5...

On April 21st, at LUISS Guido Carli, the CISE convened a panel of international scholars to attend a one-day brainstorming workshop on the feasibility of a research agenda dedicated to the increasing political instability across Western countries, and its relationship with economic change in recent decades. The program featured, among scholars from top international institutions (see below), the presence of Nobel laureate Michael Spence.

(traduzione a cura di Elisabetta Mannoni) Notwithstanding Macron’s victory, the result of the French Presidential election is the prove that an earthquake hit the political setting in France with the exclusion – for the very first time since 1958 – of both pillars of Fifth Republic, the socialist and the Gaullist parties. The second round between Emmanuel Macron and Marine Le Pen perfectly represents the increased relevance of a new dimension of competition, different from the left-right one that had prevailed so far. A dimension which is orthogonal with respect to the left-right axis, and for which the scientific research has...

Nicola Maggini, Lorenzo De Sio and Mathilde van Ditmars Following on the tools provided by issue yield theory (De Sio and Weber 2014), this analysis provides a specific perspective on the data we at CISE collected through a CAWI survey few weeks before the Dutch election. We rely here on an innovative measurement of positional issues, which allows to derive a common issue yield index for this kind of issues. Positional issues are, in general, defined by reference to two rival goals (e.g. progressive vs. traditional morality): the issue yield measure permits us to assess the presence of strategic issue opportunities for a...
