To predict our future, we must look to the extremes. So argues the economist Richard Davies, who takes readers to the margins of the modern economy and beyond. These extreme economies illustrate the forces that test human resilience, drive societies to failure, and promise to shape our collective future. Reviving a foundational idea from the medical sciences, Extreme Economies turns the logic of modern economics on its head by arguing that these outlier societies can teach us more about our own than we might imagine. By adapting to circumstances unimaginable to most of us, the people in these societies are pioneering the economic infrastructure of the future.
