Impacts of Housing Interventions on Neighborhoods in Durham County

by Cassandra Turk

Housing intervention models intended to revitalize neighborhoods and empower homeowners are frequently observed in cities across the United States. To determine the efficacy of these programs, this study analyzes the effects of a housing intervention on the price of the home and the changes in neighborhood characteristics that may lead to neighborhood stability or instability in the long run, including the home prices, the racial makeup, the median income, and crime rates of the neighborhood. To study these characteristics and how they interact with interventions, I implement a propensity score matching model to reduce variation in unobservable characteristics and to isolate the effect of interventions on the block group characteristics of interest. In addition, I implement a non-parametric kernel regression to allow for the possibility of a non-linear relationship between home prices and home interventions. The results show significant evidence that interventions increase neighborhood home values at the bottom 10th percentile and at the median of each block group, suggesting that housing interventions do serve to increase the quality of the neighborhood. However, there is evidence that these effects taper off after a certain percent of the households in the neighborhood have been intervened upon, reducing the marginal benefit of completing a new housing intervention.

Is Inclusionary Zoning a Proper Remedy for the Affordable Housing Crisis? —A Case Study of IZ Programs in New Jersey and North Carolina

By Xinchen Li

The recent decade witnessed a worsening of the affordable housing crisis across the
country. Inclusionary zoning (IZ) has been a popular municipal remedy for the crisis.
However, it is unclear whether IZ actually adds to the affordable housing stock, and
whether it achieves its goal at the expense of average homeowners. Through a case
study of New Jersey and North Carolina, this paper aims to address these two questions.The results suggest that there is no statistically significant positive relationship between the presence of IZ and the housing price in the two states, but its beneficiary effects are also debatable.
