The Census Tree is the largest-ever database of record links among the historical U.S. censuses, with over 700 million links for people living in the United States between 1850 and 1940. These high-quality links allow researchers in the social sciences and other disciplines to construct a...

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...

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...

The pandemic catalyzed an enduring shift to remote work. To measure and characterize this shift, we examine more than 250 million job vacancy postings across five English-speaking countries. Our measurements rely on a state-of-the-art language-processing framework that we fit, test, and refine...

An important gap in most empirical studies of establishment-level productivity is the limited information about workers' characteristics and their tasks. Skill-adjusted labor input measures have been shown to be important for aggregate productivity measurement. Moreover, the theoretical...

This study examines the impact of access to confidential administrative data on the rate, direction, and policy relevance of economics research. To study this question, we exploit the progressive geographic expansion of the U.S. Census Bureau's Federal Statistical Research Data Centers (FSRDCs)....

We create a firm-level ChatGPT investment score, based on conference calls, that measures managers' anticipated changes in capital expenditures. We validate the score with interpretable textual content and its strong correlation with CFO survey responses. The investment score predicts future...

In applied historical research, geographic units often differ in level of aggregation across datasets. One solution is to use crosswalks that associate factors located within one geographic unit to another, based on their relative areas. We develop an alternative approach based on relative...

The New Institutional Economics (NIE) has its early roots in Cliometrics. Cliometrics began with a focus on using neoclassical theory to develop and test hypotheses in economic history. But empirical consideration of economic and political development within and across countries is limited,...

Culture - the set of socially transmitted values and beliefs held by individuals - has important implications for a wide variety of economic outcomes. Both the causes and consequences of culture have been the subject of work in Historical Political Economy. I first outline several theories on...
