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...

Aldo Paparo, Lorenzo De Sio, Mathilde van Ditmars As seen in the analysis by Emanuele, De Sio and van Ditmars, the survey data we collected on Dutch public opinion includes data on agreement and priority of a series of important policy goals. By looking at those we were able to map the general state of Dutch public opinion and the structure of opportunity on various issue dimensions. However, the data we collected also include information concerning the credibility of each of the different parties. Basically, respondents were asked to indicate all parties that they considered credible to achieve a particular...

Vincenzo Emanuele, Lorenzo De Sio and Mathilde van Ditmars Falling in a Western European context of increasing electoral unpredictability and party system change (Chiaramonte and Emanuele 2015), the upcoming elections in The Netherlands are receiving a lot of media attention in the international press, as it is the first of a range of upcoming European elections (before France and Germany) that are expected to mark the future of European politics. Consistently with an international context where right-wing populism is on the rise, with the election of Donald Trump and the candidature of Marine le Pen, in the Netherlands, Geert Wilders’ party...

Aldo Paparo & Lorenzo De Sio (2017) PTV gap as a new measure of partisanship: a panel-data, multi-measure validation showing surprising partisanship stability, Contemporary Italian Politics, 9:1, 60-83, DOI: 10.1080/23248823.2017.1289733 Abstract Comparative studies of partisanship lack a comparable transatlantic measure. In the U.S. the traditional ANES measure is used, while in European multi-party systems a party-closeness measure is mostly used. A recent contribution proposed PTV (propensity-to-vote) gap as a potential solution to this issue, showing that the gap in PTV scores between the best- and the second best-placed party has desirable properties in the American case. In this article we test the...

Lorenzo De Sio, Mark N. Franklin, Till Weber, The risks and opportunities of Europe: How issue yield explains (non-)reactions to the financial crisis, Electoral Studies, Volume 44, December 2016, Pages 483-491, ISSN 0261-3794, http://dx.doi.org/10.1016/j.electstud.2016.06.006. Abstract The financial crisis subjected the EU to its first truly serious stress test. A majority of citizens is now opposed to further integration. But party systems have barely adjusted, instead perpetuating traditional patterns of an evasive mainstream with Euroskeptic fringes. To explain this unexpected outcome we draw on issue yield (De Sio and Weber, 2014), a general model of political competition that unites public opinion, party...
