Knowledge that Transforms

We investigate the role of gender norms in shaping parental childcare following changes in the relative take-home pay of mothers and fathers. Exploiting variation from Swedish tax reforms, we estimate the elasticity of substitution in parental childcare for native and immigrant couples from a variety of countries characterized by varying gender norms. Couples originating from countries with relatively conservative norms are more likely to reallocate childcare to mothers following a reduction in the father’s tax rate and less likely to reallocate childcare to fathers following a reduction in the mother’s tax rate, thereby reinforcing a traditional allocation of childcare across parents.

We study the consequences of job markets' heavy reliance on referrals. Referrals lead to more opportunities for workers to be hired, which lead to better matches and increased productivity but also disadvantage job seekers with few or no connections to employed workers, increasing inequality. Coupled with homophily, referrals also lead to immobility. We identify conditions under which distributing referrals more evenly reduces inequality and improves future productivity and mobility. We use the model to examine the short- and long-run welfare impacts of policies such as affirmative action and algorithmic fairness.

This paper examines the multigenerational impact of children and whether the public provision of formal childcare lessens the earnings and employment impacts of children. We find that the arrival of a firstborn reduces employment and earnings of mothers and employment of grandmothers. Studying a universal childcare program in Quebec, we find that formal childcare increases the employment rates of mothers as well as that of grandmothers to a lesser extent. Examining heterogeneity of the program’s impact across census divisions, we find a negative correlation between the positive effects on mothers’ employment and the prepolicy supply of informal childcare by grandmothers.

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.

This multi-book review argues that identity-driven polarization interacts with institutional design to erode democratic guardrails. Reading Heather Cox Richardson’s Democracy Awakening, Tom Schaller, and Paul Waldman’s White Rural Rage, and Ezra Klein’s Why We’re Polarized through an economist’s lens, I emphasize two claims. First, when institutions fail to deliver broadly shared security and dignity, anti-pluralist projects gain legitimacy and room to maneuver. Second, questions of belonging, citizenship, and the obligations of government to the people are informed by culture and institutional trust. The culture of the United States is not one that lends itself readily to ethno-nationalism, but these books make a case for an America that is, and perhaps has always, been divided by notions of who “we” are. I situate the books within the economics literature on populism, polarization, and institutions, and examine what we can learn about rebuilding both prosperity and democratic resilience in the United States.

David Autor of Massachusetts Institute of Technology and NBER reviews “The Means of Prediction: How AI Really Works (and Who Benefits)” by Maximilian Kasy. The Econlit abstract of this book begins: “Presents a framework for understanding how artificial intelligence (AI) will proceed in a society that is shaped by power and inequality, focusing on the limits of AI and how it can be made to work for all people.”
