Shifting Patterns of Social Interaction: Exploring the Social Life of Urban Spaces Through A.I.
Abstract We analyze changes in pedestrian behavior over a 30-year period in four urban public spaces located in New York, Boston, and Philadelphia. Building on William Whyte’s observational work from 1980, where he manually recorded pedestrian behaviors, we employ computer vision and deep learning techniques to examine video footage from 1979-80 and 2008-10. Our analysis…

Why Has Construction Productivity Stagnated? The Role of Land-Use Regulation
Abstract We document a Kuznets curve for construction productivity in 20th-century America. Homes built per construction worker remained stagnant between 1900 and 1940, boomed after World War II, and then plummeted after 1970. The productivity boom from 1940 to 1970 shows that nothing makes technological progress inherently impossible in construction. What stopped it? We present…

Low-Rise Multifamily and Housing Supply: A Case Study of Seattle
Abstract We provide an in-depth case study of land use reforms in Seattle to highlight how redevelopment of aging single-family housing to townhomes can lead to a significant increase in market-rate housing that promotes affordability. The key is to allow market forces to use by-right zoning to drive small-scale development, when also supported by clear…

Introducing the “More Accurate Consumer Price Index”

However, in recent years, somehave sent mixed signals to researchers about the relative merits of different measures. As aresult, academic and policy researchers routinely use theoretically and empirically inferior priceindexes…

Poverty, Hardship, and Government Transfers
Abstract We examine how the well-being of those with few resources changed, amidst economic disruption and large, transitory government transfers. We find that in the years leading up to the pandemic and in 2020, the patterns for income and consumption poverty were very similar. In 2021 and 2022, however, changes in income and consumption poverty…

The Distribution of Social Capital across Individuals and its Relationship to Income
Abstract There have been several attempts to measure social capital—the value inhering in relationships—at an aggregate level, but researchers lack comprehensive individual-level social capital measures. Using a combination of direct linkage and imputation across several nationally representative datasets, we produce a comprehensive measure of social capital at the individual level. We validate our measure by…

Race, Ethnicity, and Measurement Error
Abstract Large literatures have analyzed racial and ethnic disparities in economic outcomes and access to the safety net. For such analyses that rely on survey data, it is crucial that survey accuracy does not vary by race and ethnicity. Otherwise, the observed disparities may be confounded by differences in survey error. In this paper, we…

Employment and Labor Supply Responses to the Child Tax Credit Expansion: Theory and Evidence
AbstractThe 2021 Child Tax Credit (CTC) expansion increased government benefits to families, andespecially to families with the lowest incomes. Economic theory predicts that this policyintervention would have led to a reduction in labor supply among adults in those families. Ourreview of available research suggests that employment within broadly defined demographicgroups was not reduced by the…

Critiquing Bastian (2022, 2023, 2024, and forthcoming):On Child Tax Credit Reform and the Sensitivity of Single Mothers to Work Incentives
Abstract In 2021, Congress passed and President Biden signed a major, but temporary, reform to the Child Tax Credit (CTC). Among other reforms to the credit, the American Rescue Plan Act (ARPA) made it available to non-workers on the same basis as workers. Attempts to make this reform permanent foundered, in part, due to opposition…

Human Capital Spillovers and Health: Does Living Around College Graduates Lengthen Life?
Abstract Equally educated people are healthier if they live in more educated places. Every 10 percent point increase in an area’s share of adults with a college degree is associated with a decline in all-cause mortality by 7%, controlling for individual education, demographics, and area characteristics. Area human capital is also associated with lower disease…
