Abstract. Notwithstanding the improvement in gender equality in political power and resources in European democracies, this study shows that, on average, declared interest in politics is 16 per cent lower for women than for men in Europe. This gap remains even after controlling for differences in men's and women's educational attainment, material and cognitive resources.

Abstract. This article analyzes the extent to which the format and the “Do not know” (DK) protocol of political knowledge questions influence the size of the gender gap. By using a set of experiments that manipulated the DK protocol and the format (open vs. closed ended) of political knowledge questions in a face-to-face representative survey of the Spanish population, we show that the format of the questions (open vs. closed ended) is not relevant in explaining the gender gap.

Abstract: We explore how microwork platforms manage difficult tasks in paid crowdsourcing environments. We argue that as human computation becomes more prevalent, notably in the context of big data ecosystems, microwork platforms might have to evolve and to take a more managerial stance in order to provide the right incentives to online workers to handle difficult tasks.

Abstract. We analyze the impact of failed land reform on peasant conflict in Spain before the Civil War using a municipal data set with monthly observations of peasant conflict in Andalusia from April 1931 to July 1936. We find temporary occupations of land were rare and not correlated with either organized reaction to land reform or the existence of a large pool of beneficiaries.

Abstract. Conflicting theories and mixed empirical results exist on the relationship between ethnic diversity and trust. This article argues that these mixed empirical results might be driven by contextual conditions. We conjecture that political competition could strengthen ethnic saliency and, in turn, salient ethnic identities can activate or intensify in-group trust and depress trust in members of other ethnic groups. We test this conjecture using the move toward secession in Catalonia, Spain.
