We present a new aggregation method - called SVM algorithm - and use this technique to produce novel measures of democracy (186 countries, 1960-2014). The method takes its name from a machine learning technique for pattern recognition and has three notable features: it makes functional...

We present a novel approach for measuring democracy based on Support Vector Machines, a mathematical algorithm for pattern recognition. The Support Vector Machines Democracy Index (SVMDI) is continuously on the 0-1-interval and enables a very detailed measurement of democracy for 188 countries...

We show that culture and diversity strongly influence welfare systems around the globe. To disentangle culture from institutions, we employ regional instruments as well as data on the prevalence of the pathogen Toxoplasma Gondii, linguistic differences, and the frequency of blood types. The...

Many experts claim that the incidence of suicide attacks is driven by religious cleavages. To test this hypothesis, we investigate whether the total number of suicide attacks per violent conflict or the annual number of suicide attacks per country is associated with simmering religious...

Social justice is a topic of importance to social scientists and also political decision makers. We examine the relationship between globalization and social justice as measured by a new indicator for 31 OECD countries. The results show that countries that experienced rapid globalization enjoy...

Group-based identity undermines democracy by impeding democratic change of government. A substantial literature has therefore studied how to make democracy consistent with group identity. We contribute to this literature by introducing the role of group decisiveness into voting incentives and...

The United Nations Goldstone Report criminalized self-defense against state-sponsored or state-perpetrated terror. We use voting on the two UN General Assembly resolutions relating to the Goldstone Report to study whether support for the Goldstone principle of criminalization of self-defense...

We investigate a case of political favoritism. Some members of the Bavarian parliament hired relatives as office employees who were paid using taxpayers’ money. We examine whether being involved in the scandal influenced re-election prospects and voter turnout. The results do not show that...

Is human capital a robust predictor of good institutions? Using a new institutional quality measure, the International Property Rights Index (IPRI), we find that cognitive skill measures are significant, robust, and large in magnitude. We use two databases of cognitive skills: estimates of...

We examine moonlighting by politicians in Germany. In July 2007, the German Supreme Court adjudicated that members of parliament (MPs) have to publish details of their outside earnings. Using panel data models, we investigate how outside earnings are correlated with absence and parliamentary...
