A compact but complete handbook of zoning covering the story of the spread of this movement, the reasons for zoning, the experiences of various zoned cities, the correct principles and best practice, the legal pitfalls and a selected list of reference.
EDWARD M. BASSETT was chairman of the Zoning Committee of New York.
The California Dream Act and CADAA opened access to state Cal Grants for undocumented students who cannot receive federal aid. Using the universe of CADAA applications, this study employs a regression discontinuity design around annual Cal Grant offer cutoffs to estimate intention-to-treat effects of scoring above the threshold on educational outcomes. A fuzzy RDD uses score-relative-to-cutoff as an instrument for actual grant receipt to estimate local average treatment effects.
Truth in Sentencing (TIS) reforms eliminated parole, standardized release dates, and generally lengthened sentences in many states around 1999–2000. This study uses Wisconsin’s TIS implementation (effective December 1999) and a sharp regression discontinuity design around the policy cutoff to estimate causal effects on sentencing length, recidivism, and labor-market reentry for formerly incarcerated people.
Dual Language Immersion (DLI) programs aim to promote bilingualism and boost academic and long-run economic outcomes for English learners (ELs) and non-ELs. This project uses longitudinal student-level data from Texas and the staggered rollout of DLI programs across cohorts to estimate causal impacts on short- and long-run outcomes: test scores, high-school graduation, college enrollment and completion, and adult wages.
The H-1B visa cap has been fixed at 85,000 since 2004 while demand for skilled clinicians has risen, potentially affecting where immigrant clinicians work and patient access to care. This project leverages the cap-exempt status of research-affiliated nonprofit hospitals—institutions that can hire without lottery exposure—to create quasi-experimental variation when the cap binds.
To identify causal effects of women’s entry into paid professional work, this project exploits historical teacher certification exams as a quasi-random barrier into one of the early white-collar occupations available to women. By linking teacher-exam records to census data and applying a regression discontinuity design around passing thresholds, the study estimates how access to the teaching profession affected women’s labor-market outcomes, marriage, and fertility.
Many Earned Income Tax Credit (EITC) claimants pay for tax preparation services they could obtain free and more accurately through VITA (Volunteer Income Tax Assistance). In Michigan, only 1.4% of EITC returns use VITA while 49% use paid preparers, who often face no competency standards. This study uses a field experiment to understand why low-income households choose paid preparers despite higher costs and error rates, and to test whether targeted information about VITA’s availability, quality, and convenience shifts behavior.
This paper investigates how the early-20th-century expansion of mail-order kit housing—factory-produced home kits sold and shipped by rail—changed towns’ access to homeownership and long-term intergenerational outcomes. Using newly digitized data on kit-housing firm mill locations, firm sales records, and full-count census data, the study exploits spatial variation in transportation costs to identify exogenous differences in access to kit housing across towns.
School hours often misalign with parents’ workdays, leaving gaps in childcare for school-age children. This study focuses on how increased afterschool care availability affects mothers’ employment, earnings, and full-time work. It leverages variation from competitive 21st Century Community Learning Center Grants—federal funds awarded to expand afterschool programs—and links grant data to restricted administrative records.
Early jobs shape immigrants’ long-term economic trajectories. U.S. refugee policy emphasizes rapid employment, but many newcomers enter sectors with limited mobility. This project studies whether early access to warehouse employment—an expanding, immigrant-heavy employer—promotes upward mobility or entrenches low-wage attachment. Exploiting the staggered openings of large warehouse facilities across U.S. cities (2005–2025), the study uses a staggered difference-in-differences design to estimate impacts of early warehouse exposure on employment, earnings, and career mobility.
