The principal findings of experimental economics are that impersonal exchange in markets converges in repeated interaction to the equilibrium states implied by economic theory, under information conditions far weaker than specified in the theory. In personal, social, and economic exchange, as studied in two-person games, cooperation exceeds the prediction of traditional game theory. This book relates these two findings to field studies and applications and integrates them with the main themes of the Scottish Enlightenment and with the thoughts of F. A. Hayek.

Summary: Unique insights plus an enjoyable read
Rating: 5

I read a lot of books about economics. Until reading Rationality in Economics, I had not read an economics book that gave me precisely what I want: (1) genuine insights on a wide range of important issues, (2) a feel for the key contributions in the academic literature with a minimum of technical detail, and (3) a writing style that explains so much in straightforward language that reading the book becomes a uniquely enjoyable learning experience. So, if you want to share that experience, read Rationality in Economics by the Nobel prize winning economist Vernon Smith. A major theme is the interplay between constructivist rationality (logical thinking) and ecological rationality (selection over time of what works best that results in our cultural and biological heritage). Gaining an appreciation for these two types of rationality illuminates the work of Adam Smith and Friedrich Hayek and also provides a healthy skepticism of "fix the economy" proposals from Washington. Wealth creation through specialization, innovation, and trade that meet existing needs and create new needs is facilitated by markets. Important to understand how markets work, right? Vernon's Nobel prize was awarded for his pioneering contribution to experimental economics that uses laboratory experiments to test hypotheses about how markets function --- the behavior of participants and the institutional rules of the game. This book is a beautiful summary of experimental economics. Along the way, we learn about smart ways to deregulate markets guided by laboratory experiments (what California politicians failed to do when they deregulated a portion of that state's electricity market). We learn how to think about market efficiency and the apparent conflicting view of behavioral anomalies. We learn about how decision making relates to the way in which our brains have evolved (neuroeconomics). Perhaps you have felt uneasy about the widely-touted superiority of Bayesian decision making and related handling of probabilites. The Psychology and Markets chapter contains an elegant explanation of why you should be critical (hint: surprises are important). The Rationality in Science chapter addresses the age-old dilemma of how we know what we think we know. Vernon's answer is an absolute treasure that everyone should read and ponder. These brief highlights give some indication of why Rationality in Economics is the most useful economics book that I have read.
