The Undercover Economist - famed for his explanations - now offers solutions. Tim Harford introduces a new way of thinking about how to solve the world's most urgent problems, from climate change to terrorism, African poverty to global finance - even the problems we encounter in our own daily lives. When faced with such challenges, we instinctively look to leaders, experts, and gurus to provide us with pre-chewed solutions. Harford argues that the world has become too unpredictable and complex for that. Instead, we must adapt - improvise rather than plan, work from the bottom up, take baby steps. Adapt draws on exciting new work by passionate young economists and on innovative ideas from across the sciences. It looks at how and why innovation really comes about, extolling the value of trial and error and arguing that we should learn to embrace failure. Above all, Adapt applies hard-won lessons learned in the field, from a spaceport in the Mojave Desert to the street of Iraq, from a blazing offshore drilling rig to the frozen tundra of Siberia. The book shows that it's up to individuals - us - to change the world.
