Recent studies based on 20th century US data conclude that abortion access raises children's average socioeconomic outcomes. We generalize a model of fertility, highlighting assumptions under which these abortion predictions can be reversed. Using 19th century abortion restrictions, we...

We study differences in economic outcomes by perceived skin tone among African Americans using full-count U.S. decennial census data from the late-19th and early-20th centuries. Comparing children coded as "Black" or "Mulatto" by census enumerators and linking these children across population...

Digital technologies are bringing vast improvements to modern society but also carry the risk of perpetuating disparities if adopted at lower rates by underserved communities. We investigate the efficiency and equity aspects of technological advancement in digital health by studying an...

Two centuries ago, in most countries around the world, women were unable to vote, had no say over their own children or property, and could not obtain a divorce. Women have gradually gained rights in many areas of life, and this legal expansion has been closely intertwined with economic...

We study the climate as a determinant of religious belief. People believe in the divine when religious authorities (the "church") can credibly intervene in nature on their behalf. We present a model in which nature sets the pattern of rainfall over time and the church chooses when optimally to...

Interpreting individual heterogeneity in terms of probability theory has proved powerful in connecting behaviour at the individual and aggregate levels. Returning to Ricardo's focus on comparative efficiency as a basis for international trade, much recent quantitative equilibrium modeling of the...

Among countries colonized by European powers during the past 500 years those that were relatively rich in 1500 are now relatively poor. We document this reversal using data on urbanization patterns and population density, which, we argue, proxy for economic prosperity. This reversal is...

How do communication costs affect the production of new ideas and inventions? To answer this question, we study the introduction of the Uniform Penny Post in Great Britain in 1840. This reform replaced the previous system of expensive distance-based postage fees with a uniform low rate of one...

This paper examines the profound challenges that transformative advances in AI towards Artificial General Intelligence (AGI) will pose for economists and economic policymakers. I examine how the Age of AI will revolutionize the basic structure of our economies by diminishing the role of labor,...
