This seminar series is about economics aspects of rivalry between religious organizations and how they interact with other dimensions of religious rivalry – theological, scientific, political. The first two seminars will be online and will propose a framework for thinking about the question. The remaining six seminars, most of which will be hybrid, will be organized as structured dialogues. I will talk to leading researchers whose knowledge of particular historical, political, anthropological and geographical contexts of religious rivalry can help us to assess the value of such an approach. All members of the University are welcome to attend. No prior knowledge will be presumed (and in particular, no familiarity with economics).
