As Generation X’s (born in the 1960s and 1970s) child bearing years draw to a close, its parenting practices are due for assessment, the topic of the book under review. The book organizes its discussion around Diana Baumrind’s three parenting styles: authoritarian, permissive, and authoritative. It chronicles the drift toward the two latter and argues that income inequality determines which one of the two will be popular. When inequality is low, less is at stake and the parenting style can be more relaxed. By contrast, high inequality pushes parents toward the achievement- oriented authoritative style. More generally, the book argues, cultural differences in parenting styles can be understood as the outcome of altruistic parents’ efforts to prepare their children for adulthood, a useful perspective when parental rights are limited, long the case in the West.

Taylor (2019) details heterogeneity in the effects of the National Industrial Recovery Act (NIRA) across industries and across time. Through first the President’s Reemployment Act (PRA) and then industry-specific “codes of fair competition,” the NIRA raised wages and restricted working hours. In some—but far from all—cases industries also used a NIRA code to collude, raising prices and restricting output. The effect of the NIRA peaked in fall 1933 and winter 1934; thereafter, compliance declined. I review the intellectual history of the NIRA, the implementation of the PRA and the NIRA codes, and Taylor’s econometric evidence on their effects. I end with a discussion of the implications of Taylor’s book for understanding the effect of the NIRA on US recovery from the Great Depression.

In an interconnected world, economic and political interests inevitably reach beyond national borders. Since policy choices generate external economic and political costs, foreign state and non-state actors have an interest in influencing policy actions in other sovereign countries to their advantage. Foreign influence is a strategic choice aimed at internalizing these externalities and takes three principal forms: (i) voluntary agreements, (ii) policy interventions based on rewarding or sanctioning the target country to obtain a specific change in policy, and (iii) institution interventions aimed at influencing the political institutions in the target country. We propose a unifying theoretical framework to study when foreign influence is chosen and in which form, and use it to organize and evaluate the new political economics literature on foreign influence along with work in cognate disciplines

This essay reviews Escape from Rome: The Failure of Empire and the Road to Prosperity by Walter Scheidel. It examines the argument that Europe’s persistent fragmentation following the collapse of the Roman Empire is responsible for the origins of the modern world. First, I consider Scheidel’s argument that the rise of Rome at the end of the first millennium BCE was relatively overdetermined, but that once Rome fell, it was highly unlikely for any subsequent empire to dominate Europe. Second, I examine the institutional consequences of this divergence in state building. Finally, I reflect on the role of counterfactuals in history.

This essay reviews Jonathan Baker’s important book, The Antitrust Paradigm: Restoring a Competitive Economy, to frame the debate over appropriate antitrust policy and enforcement. Baker argues that competition is inadequate in many US markets and that antitrust could and should be strengthened to restore competition and benefit consumers. Baker presents an unrelenting critique of what he believes is the University of Chicago’s harmful influence on what was once an effective antitrust policy. I compress Baker’s book into four issues that economists can debate and I offer an alternative view that is more supportive of the current state of industry competition, the efficacy of market forces, and the case for limited antitrust intervention.

Harry J. Holzer and Sandy Baum’s recent book, Making College Work: Pathways to Success for Disadvantaged Students, provides an excellent up-to-date review of higher education. My review first summarizes its key themes: (i) who gains from college and why, (ii) mismatch and the need for more structure, (iii) problems with remediation, (iv) financial barriers, and (v) the promise of comprehensive support. I then critique the book’s proposed solutions using some of my own qualitative and quantitative data. Some recommendations are worth considering, while others are too expensive or unlikely to make a meaningful difference without addressing the underlying lack of preparedness and motivation of college students. I argue that making mandatory some existing services, such as application assistance and advice, proactive tutoring and advising, and greater career transition support, has the most immediate potential.

Archeologists are actively working to quantitatively measure income and wealth inequality in ancient history based on available data, some of them being quite sophisticated. Timothy A. Kohler and Michael E. Smith’s Ten Thousand Years of Inequality: The Archaeology of Wealth Differences presents existing measurement efforts and insightful discussions of the challenges faced, on all continents except Oceania. These first exercises should help us over time understand better the evolution of inequality in ancient history and its determinants. Understanding better the effects of differences in institutions in the ancient past should be a crucial next step.
