In this essay, I review Sylvia Nasar's long awaited new history of economics, Grand Pursuit: The Story of Economic Genius. I describe how the book is an economic history of the period 1850–1950, with distinguished economists' stories inserted in appropriate places. Nasar's goal is to show how economists work, but also to show that they are people too—with more than enough warts and foibles to show they are human! I contrast the general view of the role of economics in Grand Pursuit with Robert Heilbroner's remarkably different conception in The Worldly Philosophers: The Lives, Times, and Ideas of the Great Economic Thinkers. I also discuss more generally the question of why economists might be interested in their history at all.

Contingent charges for financial services, such as fees for unauthorized overdrafts, are often controversial. We study the economics of contingent charges in a stylized setting with naive and sophisticated consumers. We contrast situations where the naive benefit from the presence of sophisticated consumers with situations where competition works to subsidize the sophisticated at the expense of the naive, arguably unfairly. The case for regulatory intervention in these situations depends in good part, but not only, on the weight placed on distributional concerns. The economic and legal issues at stake are well illustrated by a case on bank charges recently decided by the U.K. Supreme Court.

In Reinhart and Rogoff's economic history This Time is Different, the authors provide a panoramic view of crises from the Middle Ages to the modern era. Published just as the current global financial storm arrived, the book quickly showed how history could provide not just useful perspective but also, as we can now see, very prescient guidance in the aftermath. In the longer run, the book serves to inspire ongoing work in long-run macro-financial history.

The British Industrial Revolution is the key break in world history. Yet the timing, location, and cause of this Revolution are unsolved puzzles. Joel Mokyr's book is one of a number of recent attempted solutions. He explains the Industrial Revolution through the arrival of a particular ideology in Britain, associated with the earlier European intellectual movement of the Enlightenment. This review considers how Mokyr's “idealist” approach fares as an account of the Industrial Revolution, compared to the spate of recent proposed “materialist” explanations.

The Mirrlees Review of taxation in the United Kingdom is a landmark in the analysis of U.K. fiscal policy, and of wide interest to public finance economists around the world. This review concentrates on what we can learn from the Review about the current state of public economics and directions for future research.

In Poor Economics, Abhijit Banerjee and Esther Duflo eschew grand theorizing about poverty reduction in favor of an approach in which intelligently designed and tested small interventions, based on a scientific understanding of the lives of the poor, marginally improve their welfare. In so doing, they describe the findings from the recent large literature describing the behavior and institutions of the poor and the consequences of policy and experimental interventions targeted to poverty populations. In this review, I assess whether “thinking small” with its associated policy regime of transfers, subsidies, and nudges, is both a practical and effective policy prescription for “fighting” poverty and whether the set of studies that have focused on populations that have not escaped poverty has improved our fundamental understanding of both the consequences and causes of poverty.

The Mirrlees Review is an ambitious and comprehensive analysis of the British tax system with detailed recommendations for reform. This review essay focuses on those issues that are also likely to be of interest to an American reader. The Review has the technical sophistication that readers would expect from a team of ten economists, chaired by James Mirrlees, the distinguished theorist who received the Nobel Prize for his contributions to the theory of optimal taxation. But it is written for a broader audience, explaining concepts like deadweight loss and the elasticity of tax revenue with respect to tax rates and doing so without any mathematics.
