This article explores the relationships between post-Keynesian economics and feminist economics. It distinguishes three key concepts in each tradition that recommend serious attention in the other tradition: gender, the household and unpaid work and caring as key concepts in feminist economics; uncertainty, market power and endogenous dynamics as core concepts in post-Keynesian economics. This article will show, with reference to the literature in which such cross-fertilisation has been explored already, how both traditions can be enriched from a stronger mutual engagement.
