Knowledge that Transforms

Editor's Note Our policy is to annotate all English-language books on economics and related subjects that are sent to us. A very small number of foreign-language books are called to our attention and annotated by our consulting editors or others. Our staff does not monitor and order books published; therefore, if an annotation of a book does not appear six months after the publication date, please write to us or the publisher concerning the book.

The list below specifies doctoral degrees conferred by U.S. and Canadian universities during academic year July 2017 to June 2018. Lists of degree recipients and subject classifications are provided by the university. Note: Dissertations without classifications may be found under “Y Miscellaneous Categories.”

In The Color Factor: The Economics of African-American Well-Being in the Nineteenth-Century South, Howard Bodenhorn investigates the origins, health, and socioeconomic performance of mixed-race people in the antebellum Southern United States. The central conclusion of the book is that mixed-race people fared better than darker-skinned blacks on nearly every dimension; however, they were still disadvantaged relative to whites. This review essay discusses the book's valuable data contributions and relates Bodenhorn's conclusions to the broader literature on colorism. I close with implications for future research on the economics of skin color. (JEL I12, I31, J15, J31, J71, N31)

The categories listed below are used to classify books, book reviews, journal articles, and dissertations indexed in JEL, JEL on CD, and EconLit. New changes to the classification system appear as soon as possible on www.econlit.org . The JEL classification system may be used freely for scholarly purposes. We suggest the following format: “JEL: A10, B10, etc.”

The book Moral Tribes: Emotion, Reason, and the Gap between Us and Them, by Joshua Greene, invites the reader to give a new look at the foundation of ethics and, by implication, to policy. Its specific strength is the systematic integration of new methods from neuroscience into a very old debate. Having something new and substantial to add in an investigation that has been at the center of the philosophical debate in Western civilization for twenty-five centuries is remarkable. While I invite everyone to read and enjoy this wonderful book, I take here the opportunity to invite economists to take the challenge. We are particularly interested in the question, “Is there a specific contribution that economics can give to this debate?” I believe there is and this insight is now in danger of being lost. This is my attempt to indicate where the research should look now. Maybe it is not too late. (JEL D12, D63, D87, Z13)

In The Curse of Cash, Rogoff (2016) makes two arguments. (i) Large denominations of currency are primarily used for illegal activity. Therefore, eliminating them would have benefits that far outweigh the costs in terms of lost seigniorage. (ii) The zero lower bound (ZLB) on the interest rate implied by the possibility of holding large amounts of currency is a costly constraint on central-bank policy. The best way to eliminate the ZLB is to eliminate all but small denominations of currency, ten dollars and lower, and to have those be in the form of coins. The style of the book, no models and no symbols, works fairly well for (i), but not so well for (ii). For (ii), the author is unclear about a crucial matter: what fiscal policy accompanies alternative interest-rate settings chosen by the central bank? ( JEL E26, E42, E43, E52, E58, E62)

I review The End of Alchemy by Mervyn King, published by W. W. Norton and Company in 2016. I discuss King’s proposed regulatory reform, the “pawnbroker for all seasons” (PFAS), and I compare it to an alternative solution developed in my own work. I argue that unregulated trade in the financial markets will not, in general, lead to Pareto-optimal allocations. As a consequence, solutions like the PFAS that correct problems with existing institutions are likely to be circumvented by the development of new ones. (JEL D81, D82, E44, G01, G18, G28, L51)
