New Economics Foundation Executive Director Stewart Wallis speaks with Edie Lush at Hub Davos. New Economics Foundation is involved both research and action. The 'four horsemen of economics' - that the economy is unstable, unsustainable, unfair and makes us unhappy drives what the NEF does. The NEF is working in communities across the UK to start local businesses, from local banks to new pizza delivery companies to putting local currencies like the Brixton Pound online.
