In writing this paper I benefited greatly from information provided by visiting scholars (at Berkeley) from the Soviet Union, Hungary, Czechoslovakia, Poland, and Yugoslavia. To them, and to the following friends and colleagues, I am deeply indebted not only for stimulating discussions and research cooperation but also for observations based on personal experience-particularly on issues of fundamental disagreement: Carlo M. Cipolla, Gerard Debreu, Howard S. Ellis, Oldrich Kyn, Abba P. Lerner, Mark Perlman, Richard Roehl, and Benjamin Ward.

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.

M. Lee Pelton of The Boston Foundation reviews “What Universities Owe Democracy” by By Ronald J. Daniels. The Econlit abstract of this book begins: “Promotes the argument that colleges and universities are essential to the flourishing of liberal democracy, suggesting that these institutions have a responsibility to act in defense of the liberal democratic experiment.”

Eric M. Leeper of Department of Economics, University of Virginia reviews “A Monetary and Fiscal History of the United States, 1961-2021” by Alan S. Blinder. The Econlit abstract of this book begins: “Examines monetary and fiscal policy in the United States since the 1960s, chronicling how stabilization policy struggled to fight recessions, unemployment, and inflation.”

IN THE FALL OF 1942, as the Allied and Axis nations marshalled their forces for decisive battles at Guadalcanal, El Alamein, and Stalingrad, Joseph A. Schumpeter's Capitalism, Socialism, and Democracy (CSD) was published. Perceived by Schumpeter at the time as a little book of essays somewhat in the nature of a potboiler,' it distilled for the intelligent lay reader almost forty years' thought, observation, and research (1942, p. ix) by the Austrian economist-statesman-banker turned Harvard don. Fifty years later, it remains relevant. In particular, it brought into the main stream of economic discourse the question of what market structures were most favorable to technological change and hence economic growth. Both in the United States and abroad, policy debates over that issue persist. Schumpeter's conjectures on market structure, the work by economists to extend them, and the continuing policy puzzles are the main focus of this anniversay essay. II. The Challenge

This paper reviews the economic literature on welfare reform over the 1990s. A brief summary of the policy changes is followed by a discussion of the methodological techniques that analyze the effects of these changes on outcomes. The paper then critically reviews the econometric and experimental literature on caseload changes, labor force changes, poverty and income changes, and family formation changes. A growing body of evidence suggests that recent policy changes have influenced economic behavior and well-being. One particular set of "new-style" welfare programs seems to show especially promising results, with significantly increased work and earnings and reduced poverty.

The paper then critically reviews the econometric and experimental literature on caseload changes, labor force changes, poverty and income changes, and family formation changes. A growing body of evidence suggests that the recent policy changes have influenced economic behavior and well-being in a variety of ways. One particular set of "new-style" welfare programs seems to show especially promising results, with significantly increased work and earnings and reduced poverty.

E BEGAN to conceptualize average total cost functions during the early decades of the twentieth century. But a century before, a German music publishing firm calculated and used in its internal decision making output-dependent average cost estimates for two methods of printing sheet music. This note describes that early experience and juxtaposes against it the relatively late emergence of the ATC curve in the formal literature of economics.
