The publication of Daniel Kahneman's book, Thinking, Fast and Slow, is a major intellectual event. The book summarizes, but also integrates, the research that Kahneman has done over the past forty years, beginning with his path-breaking work with the late Amos Tversky. The broad theme of this research is that human beings are intuitive thinkers and that human intuition is imperfect, with the result that judgments and choices often deviate substantially from the predictions of normative statistical and economic models. In this review, I discuss some broad ideas and themes of the book, describe some economic applications, and suggest future directions for research that the book points to, especially in decision theory.

Between 1980 and 2005, as the world embraced free market policies, living standards rose sharply, while life expectancy, educational attainment, and democracy improved and absolute poverty declined. Is this a coincidence? A collection of essays edited by Balcerowicz and Fischer argues that indeed reliance on free market forces is key to economic growth. A book by Stiglitz and others disagrees. I review and compare the two arguments.

Explanations of unethical behavior often neglect the role of competition, as opposed to greed, in assuring its spread. Using the examples of child labor, corruption, "excessive" executive pay, corporate earnings manipulation, and commercial activities by universities, this paper clarifies the role of competition in promoting censured conduct. When unethical behavior cuts costs, competition drives down prices and entrepreneurs' incomes, and thereby reduces their willingness to pay for ethical conduct. Nonetheless, I suggest that competition might be good for ethical behavior in the long run, because it promotes growth and raises incomes. Higher incomes raise the willingness to pay for ethical behavior, but may also change what people believe to be ethical for the better.

Economic theory and evidence from a variety of debt markets shed light on current reform proposals concerning emerging market debt. Debt markets, including the U.S. municipal bond market, generally function best when the rights of creditors are protected most effectively.
