How did we evolve from ancient hunter-gatherers to modern consumer-traders? Why are people so irrational when it comes to money and business? Bestselling author Dr. Michael Shermer argues that evolution provides an answer to both of these questions through the new science of evolutionary economics. Drawing on research from neuroeconomics, Shermer explores what brain scans reveal about bargaining, snap purchases, and how trust is established in business. Utilizing experiments in behavioral economics, Shermer shows why people hang on to losing stocks and failing companies, why business negotiations often disintegrate into emotional tit-for-tat disputes, and why money does not make us happy. Employing research from complexity theory, Shermer shows how evolution and economics are both examples of a larger phenomenon of complex adaptive systems. Along the way, Shermer answers such provocative questions as: Do our tribal roots mean that we will always be a sucker for brands? How is the biochemical joy of sex similar to the rewards of business cooperation? How can nations increase trust within and between their borders? Finally, Shermer considers the consequences of globalization and what will happen if nations allow free trade across their borders.
