Using illustrations from research on inequality, this paper offers evidence the strengths of ‘behavioural synthesis’, i.e. reconciliation between neoclassical and behavioural economics. We compare how theoretical models absolute relative inequality have evolved assumptions income maximization to status-seeking competition, altruism. emphasize relevance experiments in testing competing theories ...

In this exploratory paper we propose ‘worldmaking’ as a framework for pluralistic, imaginative scenario development. Our points of departure are the need in scenario practice to embrace uncertainty, discomfort and knowledge gaps, and the connected need to capture and make productive fundamental plurality among understandings of the future. To help respond to these needs, we introduce what Nelso...
