Neoclassical economics has so deeply entrenched the notion that markets are better than all other ways of organising life, that decisions escape rational scrutiny. All models use a few simplifying assumptions, but those underpinning mainstream economics more often distort and detach from reality. That’s why new groups are emerging to promote heterodox economics, which draws on the insights of the study of complexity, neuro and behavioural science, ecology, feminism and the core economy of family, mutualism and community.
