RBC Methodology and the Development of Aggregate Economic Theory
This essay reviews the development of neoclassical growth theory, a unified theory of aggregate economic phenomena that was first used to study business cycles and aggregate labor supply. Subsequently, the theory has been used to understand asset pricing, growth miracles and disasters, monetary economics, capital accounts, aggregate public finance, economic development, and foreign direct investment. {{p}} The focus of this essay is on real business cycle (RBC) methodology. Those who employ the discipline behind the methodology to address various quantitative questions come up with ...

The Slaughter of the Bison and Reversal of Fortunes on the Great Plains
In the late 19th century, the North American bison was brought to the brink of extinction in just over a decade. We show that the bison?s slaughter led to a reversal of fortunes for the Native Americans who relied on them. Once the tallest people in the world, the generations of bison-reliant people born after the slaughter were among the shortest. Today, formerly bison-reliant societies have between 20-40% less income per capita than the average Native American nation. We argue that federal Indian policy that limited out-migration from reservations and restricted employment opportunities to ...

Institutions Do Not Rule: Reassessing the Driving Forces of Economic Development
The pursuit to uncover the driving forces behind cross-country income gaps has divided economists into two major camps: One emphasizes institutions, while the other stresses non-institutional forces such as geography. Each school of thought has its own theoretical foundation and empirical support, but they share an implicit hypothesis?the forces driving economic development remain the same regardless of a country?s stage of development. Such hypothesis implies a theory that the process of development in human history is a continuous improvement in income levels, driven by the same forces, and ...

The Effect of Fertility on Mothers’ Labor Supply over the Last Two Centuries
This paper documents the evolving impact of childbearing on the work activity of mothers. Based on a compiled dataset of 441 censuses and surveys between 1787 and 2015, representing 103 countries and 48.4 million mothers, we document three main findings: (1) the effect of fertility on labor supply is small and typically indistinguishable from zero at low levels of development and economically large and negative at higher levels of development; (2) this negative gradient is remarkably consistent across histories of currently developed countries and contemporary cross-sections of countries; and ...

Structural Change in Labor Supply and Cross-Country Differences in Hours Worked
This paper studies how structural change in labor supply along the development spectrum shapes cross-country differences in hours worked. We emphasize two main forces: sectoralreallocation from self-employment to wage work, and declining fixed costs of wage work. We show that these forces are crucial for understanding how the extensive margin (the employment rate) and intensive margin (hours per worker) of aggregate hours worked vary with income per capita. To do so we build and estimate a quantitative model of labor supply featuring a traditional self-employment sector and a modern ...

Cross-border Patenting, Globalization, and Development
We build a stylized model that captures the relationships between cross-border patenting, globalization, and development. Our theory delivers a gravity equation for cross-border patents. To test the model’s predictions, we compile a new dataset that tracks patents within and between countries and industries, for 1980-2019. The econometric analysis reveals a strong, positive impact of policy and globalization on cross-border patent flows, especially from North to South. A counterfactual welfare analysis suggests that the increase in patent flows from North to South has benefited both ...

Mapping Our Community: Residential Segregation in Mt. Airy and in Philadelphia
The West Mt. Airy neighborhood of Philadelphia has been nationally recognized for its efforts to intentionally promote racial integration and neighborhood stability since the 1950s.1 In the more than 50 years since then, residents understand the challenges to integration through a new lens and remain passionate about creating a neighborhood of diversity and inclusion. A contemporary challenge to racial integration in Mt. Airy focuses on the concern that rising housing costs will lead to the displacement of current residents and will inhibit lower-income residents from moving into the ...
