Knowledge that Transforms

Happiness is generally considered to be an ultimate goal in life; virtually everybody wants to be happy. The United States Declaration of Independence of 1776 takes it as a self-evident truth that the “pursuit of happiness” is an “unalienable right”, comparable to life and liberty. It follows that economics is – or should be – about individual happiness. In particular, the question is how do economic growth, unemployment and inflation, as well as institutional factors such as good governance, affect individual well-being? In addition to this intrinsic interest, there are three major reasons for economists to consider happiness. The first is economic policy. At the micro-level, it is often impossible to make a Pareto-optimal proposal, because a social action entails costs for some individuals. Hence an evaluation of the net effects, in terms of individual utilities, is needed. On an aggregate level, economic policy must deal with trade-offs, especially those between unemployment and inflation. Using happiness data for twelve European countries and the period 1975 to 1991, it has (cautiously) been calculated that a one percentage point increase in the unemployment rate is marginally compensated for by a 1.7 percentage point decrease in inflation (Rafael Di Tella, Robert MacCulloch, and Andrew Oswald 2001). This result significantly deviates from the “misery index ” which, for lack of information, has simply been defined as the sum of the percent unemployment rate and the percent annual inflation rate. Another trade-off that can be

This excellent book provides the reader with a broad introduction to, and a powerful advocacy of, behavioral finance. In the tradition of the best of the Clarendon Lecture Series, Andrei Shleifer provides a clear context and motivation for a collection of his influential ideas in this field, emphasizing central themes that link together the wide scope of this work. Topics include: investor sentiment, the limits of arbitrage, the closed-end fund puzzle, positive feedback investment, and both market overreaction and underreaction to news, as well as general discussions on the motivation for this research and promising future directions.

In Special Interest Politics Gene Grossman and Elhanan Helpman examine how special-interest groups influence political outcomes for the benefit of their members. The authors take interest groups seriously by considering a range of theories and supporting evidence on interest group activity. Their book provides perspectives on how to study interest group politics and a set of methods for that study. Although the authors present a number of standard models, the book contains much that is new. The reader takes away a multitude of results, tools, models, and new research ideas. The result is an outstanding book full of insight, useful methods, and perspective.

In this review, I summarize and offer thoughts about two arguments key to Glenn Loury's analysis of the anatomy of racial inequality. The first concerns the idea that many negative stereotypes held about blacks in the United States are self-fulfilling, despite little evidence of inherent differences between the races in human potential. The second argument concerns the proposition that the racial stigmatization of blacks is deeply embedded in the public consciousness and that such stigma racially biases socially cognitive processes to the severe detriment of African-Americans.
