David Friedman has never taken an economics class in his life. Sure, he's taught economics at UCLA. Chicago, Tulane, Cornell, and Santa Clara, but don't hold that against him. After all, everyone's an economist. We all make daily decisions that rely, consciously or not, on an acute understanding of economic theory--from picking the fastest checkout tine at the supermarket to voting or not voting, from negotiating the best job offer to finding the right person to marry. Hidden Order is an essential guide to rational living, revealing all you need to know to get through each day without being eaten alive. Friedman's wise and immensely accessible book is perfect for amateur economists, struggling economics students, young parents and professionals--just about anyone who wants a clear-cut approach to why we make the choices we do and a sensible strategy for how to make the right ones.
