Knowledge that Transforms

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.”

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.

Scoring systems can help to identify patients at risk for a CMV infection and minimize resource consumption and delay in treatment. Due to low incidence, a 2-step-algorithm, consisting of the Münster Score followed by a CMV-PCR if the score indicates a CMV infection, is preferable.

Why is modern society capable of cumulative innovation? In A Culture of Growth: The Origins of the Modern Economy, Joel Mokyr persuasively argues that sustained technological progress stemmed from a change in cultural beliefs. The change occurred gradually during the seventeenth and eighteenth centuries and was fostered by an intellectual elite that formed a transnational community and adopted new attitudes toward the creation and diffusion of knowledge, setting the foundation for the ethos of modern science. The book is a significant contribution to the growing literature that links culture and economics. This review discusses Mokyr’s historical analysis in relation to the following questions: What is culture and how should we use it in economics? How can culture explain modern economic growth? Will the culture of growth that caused modern prosperity persist in the future?

Ran Abramitzky's book, The Mystery of the Kibbutz: Egalitarian Principles in a Capitalist World, tries to answer the questions of why the communal kibbutz worked so well in Israel's formative years and what limits its current success in modern Israel. Initial ideological commitment and the special circumstances of Israel's founding led to unusual success when combined with well-thought-out rules on behavior and entry. Over time, the commitment to socialistic income sharing has not worked so well, given modern technology and global commerce. The author links up these ideas to the broader issue of organizational structure but misses out on some opportunities to test the ideas further.

In their recent book, Where Economics Went Wrong, David Colander and Craig Freedman (2019) argue that economics went wrong when it abandoned the Classical liberal firewall that demanded separation of scientific theory from the art of policy making. Colander has long advanced the idea that applied economics should be classified neither as positive nor as normative economics. Instead, it should be placed in a third category, “the art of economics”; art requires vision and acumen in addition to knowledge and technique, and is thus more akin to engineering than the natural sciences. The primary contribution of Where Economics Went Wrong is thus to advance Colander’s general argument through the specific story of Chicago economics. This essay make two interconnected claims. First, while I agree with Colander and Freedman that applied economics would benefit from more art and less calculation, the Chicago school is not the best vehicle by which to tell a convincing story. Second, a thicker history of the Chicago school reminds us of the importance of institutions and rules, not only for understanding the economy but also for thinking about how economists have constructed our discipline and how internal institutions and incentives affect our behavioral choices.

Designing marketplaces in complex settings requires both novel economic theory and real-world engineering, often drawing upon ideas from fields such as computer science and operations research. In Discovering Prices: Auction Design in Markets with Complex Constraints, Milgrom (2017) explains the theory and design of the United States’ “incentive auction” that reallocated wireless spectrum licenses from television broadcasters to telecoms. Milgrom’s account teaches us how economic designers can grapple with complexity both in theory and in practice. Along the way, we come to understand several different types of complexity that can arise in marketplace design.

In this essay, I reflect on textbook writing after three decades of participating in the activity. I address the following questions: What perspective should textbooks take? What is the best approach to teaching microeconomics? What is the best approach to teaching macroeconomics? How does the content of the introductory course evolve? How much material should textbooks include? Are textbooks too expensive? How is digital technology changing the market for textbooks? Who should become a textbook author?

This paper revisits Friedrich Hayek’s book, The Road to Serfdom, on the seventy-fifth anniversary of its publication. Though the book is well-known, its arguments are often mischaracterized. The paper traces the origins of the book, noting the various people and arguments that Hayek was responding to, and places it in the context of its times. The structure of the book is explored and some common criticisms addressed. Finally, it is shown how, after its publication, the book took on a life of its own.

The Coase theorem is one of the most influential and controversial ideas to emerge from post–World War II economics. This article examines the theorem’s origins, diffusion, and the wide variety of uses to which it has been put by economists and others over the sixty years since Coase published “The Problem of Social Cost.” Along the way, we explore the ambiguity and controversy surrounding the theorem, develop a Coase theorem that is valid as a proposition in economic logic, and probe the implications of all of this for the use of the Coase theorem going forward.
