To understand how humans react and adapt to economic change we need to study people who live in harsh environments. From death-row prisoners trading in institutions where money is banned to flourishing entrepreneurs in the world's largest refugee camp, from the unrealised potential of cities like Kinshasa to the hyper-modern economy of Estonia, every life in this book has been hit by a seismic shock, violently broken or changed in some way. People living in these odd and marginal places are ignored by number crunching economists and political pollsters alike. Science suggests this is a mistake. This book tells the personal stories of humans living in extreme situations, and of the financial infrastructure they create. Here, economies are not concerned with the familiar stock market crashes, housing crises, or banking scandals of the financial pages. In his quest for a purer view of how economies succeed and fail, Richard Davies takes the reader off the beaten path to places where part of the economy has been repressed, removed, destroyed or turbocharged. By travelling to each of them and discovering what life is really like, Extreme Economies tells small stories that shed light on today's biggest economic questions.
