Drawing on identity and social comparison theories, we propose and test a model of motivation to lead based on two types of self-to-role comparisons (i.e., self-comparisons with specific leaders and with more abstract representations of the leadership role). We propose that these comparisons...

Social Darwinism suggests that in crisis situations leaders have to be replaced by better fitting leaders. An opposing school argues that leaders, based on their personality, are successful in all situations and therefore can master all situations including a crisis. A third view concludes that...

The analysis of a quarterly panel of ten countries covering 75 percent of the worldwide opera performances through the years 2014 to 2018 showed that the number of performances depend positively on growth and strongly negatively on unexpected inflation. Furthermore, highly significant country...

At its core, the discussion on the micro-macro link in heterodox economics is concerned with the correct treatment of aggregates and aggregation in social theory. In this chapter we survey heterodox approaches to the micro-macro link with a focus on shared understandings and convictions that...

This paper investigates the emergence of polarisation patterns in the EU during the last 60 years from a structuralist and complexity economics perspective. Based on the results, feasible opportunities for EU policy-making, which aim to counteract a tendency of polarization, are delineated. The...

We investigate the computational complexity of several decision problems in hedonic coalition formation games and demonstrate that attaining stability in such games remains NP-hard even when they are additive. Precisely, we prove that when either core stability or strict core stability is under...

The existing literature identifies patent thickets indirectly. In this paper we propose a novel measure based on patent citations which allows us to measure the density of patent thickets directly. We discuss the algorithm which generates the measure and present descriptive results validating...
