Loss aversion is one of the most widely used concepts in behavioral economics. We conduct a large-scale, interdisciplinary meta-analysis to systematically accumulate knowledge from numerous empirical estimates of the loss aversion coefficient reported from 1992 to 2017. We examine 607 empirical estimates of loss aversion from 150 articles in economics, psychology, neuroscience, and several other disciplines. Our analysis indicates that the mean loss aversion coefficient is 1.955 with a 95 percent probability that the true value falls in the interval [1.820, 2.102]. We record several observable characteristics of the study designs. Few characteristics are substantially correlated with differences in the mean estimates.

Social learning is the updating of beliefs based on observation of others. Such observation can lead to efficient aggregation of information, but also to inaccurate decisions, fragility of mass behaviors, and, in the case of information cascades, to complete blockage of learning. We review the theory of information cascades and social learning and discuss important themes, insights, and applications of this literature as it has developed over the last 30 years. We also highlight open questions and promising directions for further theoretical and empirical exploration.

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.

Charles Betsey of Howard University reviews “Hope and Healing: Black Colleges and the Future of American Democracy” by John Silvanus Wilson Jr. The EconLit abstract of this book begins: “Discusses historically Black colleges and universities (HBCUs) in the context of the larger history of American higher education, highlighting what HBCUs have done and what non-HBCUs have failed to do to actualize democracy.”

Jason Furman of Harvard University reviews “The Resilient Society” by Markus K. Brunnermeier. The Econlit abstract of this book begins: “Promotes the view that rather than attempting to avoid risks, societies that are resilient to adverse shocks should be proactively developed, addressing how a resilient social contract can be implemented either by governments or via social norms.”

Ruixue Jia of University of California, San Diego reviews “Precarious Ties: Business and the State in Authoritarian Asia” by Meg Rithmire.
