Knowledge that Transforms

This essay reviews new histories of the role of game theory and rational decision making in shaping the social sciences, economics among them, in the postwar period. The recent books The World the Game Theorists Made by Paul Erickson and How Reason Almost Lost Its Mind: The Strange Career of Cold War Rationality by Paul Erickson, Judy Klein, Lorraine Daston, Rebecca Lemov, Thomas Sturm, and Michael Gordin raise a number of complex historical questions about the interconnections among game theory, utility theory, decision theory, optimization theory, information theory, and theories of rational choice. Moreover, the contingencies of time, place, and person call into question the usefulness of economists' linear narratives about the autonomous and progressive development of modern economics. The essay finally reflects on the challenges that these issues present for historians of recent economics.

Powerful currents have reshaped the structure of families over the last century. There has been (1) a dramatic drop in fertility and greater parental investment in children; (2) a rise in married female labor-force participation; (3) a significant decline in marriage; (4) a higher degree of positive assortative mating; (5) more children living with a single mother; and (6) shifts in social norms governing premarital sex and married women’s roles in the workplace. Macroeconomic models explaining these aggregate trends are surveyed. The relentless flow of technological progress and its role in shaping family life are stressed.

In his Bottlenecks: A New Theory of Equal Opportunity, Joseph Fishkin claims he presents an entirely new way of thinking about equality of opportunity. The core of the new theory is the call for opportunity pluralism, which consists in enlarging the range of opportunities available to people at every stage in life. In this essay, we discuss how successful Fishkin is at shaking the way economists think about equality of opportunity. We identify two aspects of Fishkin's theory that deeply conflict with economic theories of equality of opportunity. Those aspects have to do with the way economists interpret the ethical values of respect for preferences and responsibility. We also argue that the way Fishkin suggests to look at opportunities can help economists fill gaps in the way they define well-being and social justice.

Climbing Mount Laurel, authored by a group of sociologists led by Douglas S. Massey, is about the efforts by Mount Laurel Township, NJ, residents to have affordable housing built in their community. From when it was first proposed in 1969 and until the first units were completed in 2000, the project faced extraordinary political opposition, caused a number of landmark court decisions, and motivated affordable-housing legislation by other US states. This review evaluates, from an economics perspective, the lessons learned, as argued by Massey et al., about the impact of affordable housing within the host community and on surrounding communities.

Capitalism and law go together in Geoffrey M. Hodgson's comprehensive analysis of the intellectual history and practical development of the capitalist system in Western Europe and North America. Given the breadth and depth of Professor Hodgson's reading in political economy and his reflections on its implications for the present and future of global capitalism, his book deserves to be widely read. Labeling his approach legal institutionalism, he argues that a legal system that supports capitalism and the market is necessary but not sufficient to sustain a fair and efficient economic system. The state makes efficient markets possible, but it must also deal with the inevitable tensions and the fundamental asymmetry between labor and capital. Tensions arise because labor cannot be used as collateral for the loans that are needed for large-scale capitalist enterprise. Hodgson has not developed the political implications of his conclusions in any detail, but his work ought to inspire research that explores the implications of his arguments for ongoing projects of nation building.

The two books being reviewed are concerned with the importance of slavery in the antebellum US South for the economic development of the Northern states. One (Schermerhorn) deals primarily with Southern financial arrangements facilitating the sales of slaves and cotton. The other (Baptist) presents a broader picture of masters' treatment of slaves, as well as how the incomes of slaveowners spurred the demand for Northern industrial production. The review argues that both books overstate the importance of slavery and cotton production for US economic growth.

Understanding the nature of capitalism has been a central theme of economics. The collapse of the Eastern Bloc and the global financial crisis spurred the reemergence of the political economy as a new frontier and the revival of interest in the nature of capitalism. János Kornai's book Dynamism, Rivalry, and the Surplus Economy: Two Essays on the Nature of Capitalism fills an important intellectual gap in understanding the dynamic nature of capitalism by comparing it with its mirror image, socialism. To further develop the themes contained in the book, serious challenges are posed theoretically and empirically, as well as in subjects, such as hybrid capitalism.

This essay reviews Dani Rodrik's superb book Economics Rules and argues that it can serve as an ideal platform for discussing what economists can and should accomplish. The essay comments on some of the major issues in contemporary economics examined in the book: whether economics is a science, the meaning of economic models, the nature of “facts” in economics, and others. It also touches on issues that the book overlooks, such as the sociology of the profession, the teaching curriculum in economics, and the dismal situation of publishing in economics.

In this article, we review the book Economic Interdependence and War by Dale C. Copeland, and take this opportunity to describe and discuss the current debate on the topic from an interdisciplinary perspective. We also provide novel insights on the measurability of dependence expectations' effects on conflict, using the interaction with geography and endowment asymmetries.

I review the economic characteristics of the climate problem, focusing on the choice of discount rates in the presence of a stock externality, risk and uncertainty/ambiguity, and the role of integrated assessment models (IAMs) in analyzing policy choices. I suggest that IAMs can play a role in providing qualitative understanding of how complex systems behave, but are not accurate enough to provide quantitative insights. Arguments in favor of action on climate issues have to be based on aversion to risk and ambiguity and the need to avoid a small but positive risk of a disastrous outcome.
