The Effects of Inclusionary Zoning on Local Housing Markets
This study evaluates the impact of Inclusionary Zoning policies on housing markets in the San Francisco, Washington D.C. and suburban Boston areas. The analysis provides local decision-makers with valuable evidence on the impacts of IZ—a popular but often-controversial affordable housing policy. The policy brief includes an update from February 2010, summarizing additional research that has been completed since the original publication in March, 2008.

How Integrated Did We Become During the 1990s?
Although levels of residential segregation remain undeniably high, this emphasis on segregation can obscure the fact that integrated communities do exist and, as one of the key findings here demonstrate, are becoming more, not less, common.

Disentangling the Racial Test Score Gap: Probing the Evidence in a Large Urban School District
We examine the size and distribution of the gap in test scores across races within New York City public schools and the factors that explain these gaps. While gaps are partially explained by differences in student characteristics, such as poverty, differences in schools attended are also important. At the same time, substantial within-school gaps remain and are only partly explained by differences in academic preparation across students from different race groups. Controlling for differences in classrooms attended explains little of the remaining gap, suggesting little role for within-school inequities in resources. There is some evidence that school characteristics matter. Race gaps are negatively correlated with school size—implying small schools may be helpful. In addition, the trade-off between the size and experience of the teaching staff in urban schools may carry unintended consequences for within-school race gaps.

The Effects of Inclusionary Zoning on Local Housing Markets
Many local governments in metropolitan areas with high housing costs are adopting inclusionary zoning (IZ) as a means of producing housing that is affordable to low- and moderate-income households without direct public subsidies. Critics charge that IZ ordinances impose additional costs on new development and may lead to reductions in supply and increases in the price of market rate housing. Advocates of IZ argue that any negative effects IZ might have on production can be mitigated through density bonuses or other cost offsets. Rigorous empirical study of the effects of inclusionary zoning ordinances has been hampered by the lack of accurate, timely data describing IZ and the land use regulatory schemes in which IZ programs fit. In this paper, we use panel data on the adoption and characteristics of IZ in the San Francisco and Washington DC metropolitan areas and the Boston-area suburbs to analyze which jurisdictions adopt IZ, how much affordable housing the programs produce and the effects of IZ on the prices and production of market-rate housing. The IZ programs among our sample jurisdictions are complex policies and exhibit considerable variation in their design, particularly across the three regions. We find that larger, more highly educated jurisdictions and those surrounded by more neighbors with IZ are more likely to adopt IZ. Whether and how many affordable units are produced under IZ depends primarily on the length of time IZ has been in place. The results from Boston-area suburbs provide some evidence that IZ has contributed to increased housing prices and lower rates of housing production. There is no evidence that IZ has constrained supply or increased prices among Bay Area jurisdictions. Limitations on the availability and quality of our data suggest that our results should be interpreted cautiously, but also suggest that IZ programs should be designed cautiously to mitigate possible negative impacts on housing supply.

Government Policies and Household Size: Evidence from New York
What determines how many adults live in a house? How do people divide themselves up among households? Average household sizes vary substantially, both over time and in the cross-section. In this paper, we describe how a variety of government policies affect living arrangements, intentionally or not. Using data from a survey of households in New York City, we find that these incentives appear to have an impact. Specifically, households receiving these housing and income subsidies are smaller on average (measured by number of adults). The impacts appear to be considerably larger than those that would occur if the programs were lump-sum transfers. Small average household size can be extremely expensive in terms of physical and environmental resources, higher rents, and possibly homelessness. Thus, we encourage policymakers to pay greater heed to the provisions built into various social policies that favor smaller households.

The Benefits of Business Improvement Districts: Evidence from New York City
This study is the first large-scale study of the impact of Business Improvement Districts on commercial property values. The report explores what these findings mean and how they can be used to better understand the role these organizations play in local economic development.

The Condominium v. Cooperative Puzzle: An Empirical Analysis of Housing in New York City
One of the enduring puzzles of New York City’s housing market is the persistence of the housing cooperative, despite the prevailing wisdom that condominiums are more valuable than cooperatives. In this article, we examine the theoretical advantages and disadvantages of cooperatives and condominiums, and apply these theoretical insights to empirically test whether there is a price premium attributable to condominium housing. We then use our findings to speculate as to why the cooperative form remains dominant in New York City and whether its dominance is likely to continue in the future. The empirical analysis is based on hedonic models of house values and uses rich data on apartments sold in New York City between 1984 and 2002.

What do Business Improvement Districts do for Property Owners?
The article explores on the impact of business improvement districts (BIDS) to property owners in New York City. The scheme is essential to private local governments through the businesses' pay fees to supplement the package of public services in their local area. By using difference-in-difference (DD) hedonic modeling approach, one can estimate changes in property values in BID areas compared to those non-BID areas.

The Effect of Community Gardens on Neighboring Property Values
Cities across the United States that have considerable vacant land are debating whether to foster community gardens on that land, while cities with land shortages are debating when to replace gardens with other uses. Meanwhile, many cities are looking for new ways to finance green spaces. Little empirical evidence about the neighborhood impacts of community gardens is available, however, to inform the debate or to help cities design financing schemes. This paper estimates the impact of community gardens on neighborhood property values, using rich data for New York City and a difference-in-difference specification of a hedonic regression model. We find that gardens have significant positive effects, especially in the poorest neighborhoods. Higher quality gardens have the greatest positive impact.

The Impact of Low Income Housing Tax Credit Housing on Surrounding Neighborhoods: Evidence from NYC
In this report, we examine the neighborhood impact of low income housing tax credit developments in New York City, where 42,077 units of LIHTC housing were newly constructed or rehabilitated between 1987 and 2003.
