The High Cost of Segregation: The Relationship Between Racial Segregation and Subprime Lending

This study examines whether the likelihood that borrowers of different races received a subprime loan varied depending on the level of racial segregation where they live. It looks both at the role of racial segregation in metropolitan areas across the country and at the role that neighborhood demographics within communities in New York City played.

There is a lack of consensus as to whether the relationship between the built environment and travel is causal and, if it is, the extent of this causality. This problem is largely caused by inappropriate research designs adopted in many studies. This paper proposes a new method (based on path choice) to investigate the causal effect of the pedestrian environment on the utility of walking. Specifically, the paper examines how the pedestrian environment affects subway commuters' egress path choice from a station to their workplaces in downtown Boston. The path-based measure is sensitive enough to capture minor differences in the environment experienced by pedestrians. More importantly, path
choice is less likely to correlate with job and housing location choices, and therefore largely avoids the self-selection problem. The results suggest that the pedestrian environment can significantly affect a person's walking experience and the utility of walking along a path.

Medicaid Patients at High Risk for Frequent Hospital Admission: Real-time Identification and Remedial Risks

Patients with frequent hospitalizations generate a disproportionate share of hospital visits and costs. Accurate determination of patients who might benefit from interventions is challenging: most patients with frequent admissions in 1 year would not continue to have them in the next. Our objective was to employ a validated regression algorithm to case-find Medicaid patients at high-risk for hospitalization in the next 12 months and identify intervention-amenable characteristics to reduce hospitalization risk. We obtained encounter data for 36,457 Medicaid patients with any visit to an urban public hospital from 2001 to 2006 and generated an algorithm-based score for hospitalization risk in the subsequent 12 months for each patient (0 = lowest, 100 = highest). To determine medical and social contributors to the current admission, we conducted in-depth interviews with high-risk hospitalized patients (scores >50) and analyzed associated Medicaid claims data. An algorithm-based risk score >50 was attained in 2,618 (7.2%) patients. The algorithm’s positive predictive value was equal to 0.67. During the study period, 139 high-risk patients were admitted: 60 met inclusion criteria and 50 were interviewed. Fifty-six percent cited the Emergency Department as their usual source of care or had none. Sixty-eight percent had >1 chronic medical conditions, and 42% were admitted for conditions related to substance use. Sixty percent were homeless or precariously housed. Mean Medicaid expenditures for the interviewed patients were $39,188 and $84,040 per patient for the years immediately prior to and following study participation, respectively. Findings including high rates of substance use, homelessness, social isolation, and lack of a medical home will inform the design of interventions to improve community-based care and reduce hospitalizations and associated costs.

 In March 2009, The Network in collaboration with the New York Women's Foundation will release a new report on women living in poverty in New York City.  The dynamic study will include qualitative data as well as narratives from women about the impact of poverty on communities and families.  The report will help inform funding priorities for the Foundation.

The timing of this volume could not be more opportune. It is based on a 2007 conference to honor the work of Karl "Chip" Case, who is renowned for his scientific contributions to the economics of housing and public policy. The chapters analyze risk in the housing market, the regulation of housing markets by government, and other issues in U.S. housing policy. Chapters investigate derivative markets; the role that home equity insurance can play in reducing risk; the role that the regulation of government-sponsored enterprises has played in extending credit to home purchasers in low-income neighborhoods; and the growth in the market for subprime mortgages. The impact of local zoning regulations on housing prices and new construction is also considered. This is a must read during a time of restructuring our nation’s system of housing finance.

Spending, Size, and Grade Span in K-8 Schools

Spending, Size, and Grade Span in K-8 Schools

Reorganizing primary school grade spans is a tractable and relatively inexpensive school reform. However, assessing the effects of reorganization requires also examining other organizational changes that may accompany grade span reforms. Using data on New York City public schools from 1996 to 2002 and exploiting within-school variations, we examine relationships among grade span, spending, and size. We find that school grade span is associated with differences in school size, class size, and grade size, though generally not with spending and other resources. In addition, we find class size and grade size differences in the same grade level at schools with different configurations, suggesting that school grade span affects not only school size but also class size and grade size. We find few relationships, though, between grade span and school-level performance, pointing to the need to augment these analyses with pupil-level data. We conclude with implications for research and practice.

The Neighborhood Effects of Concentrated Foreclosures

The Neighborhood Effects of Concentrated Foreclosures

As the national mortgage crisis has worsened, an increasing number of communities are facing declining housing prices and high rates of foreclosure. Central to the call for government intervention in this crisis is the claim that foreclosures not only hurt those who are losing their homes to foreclosure, but also harm neighbors by reducing the value of nearby properties and in turn, reducing local governments’ tax bases. The extent to which foreclosures do in fact drive down neighboring property values has become a crucial question for policy-makers. In this paper, we use a unique dataset on property sales and foreclosure filings in New York City from 2000 to 2005 to identify the effects of foreclosure starts on housing prices in the surrounding neighborhood. Regression results suggest that above some threshold, proximity to properties in foreclosure is associated with lower sales prices. The magnitude of the price discount increases with the number of properties in foreclosure, but not in a linear relationship.

Immigration and Urban Schools: The Dynamics of Demographic Change in the Nation's Largest School District

Immigration and Urban Schools: The Dynamics of Demographic Change in the Nation's Largest School District

The authors use a rich data set on New York City public elementary schools to explore how changes in immigrant representation have played out at the school level, providing a set of stylistic facts about the magnitude and nature of demographic changes in urban schools. They find that while the city experienced an overall increase in its immigrant representation over the 5 years studied, its elementary schools did not. Although the average school experienced little change during this period, a significant minority of schools saw sizable shifts. The change does not mirror the White flight and 'tipping' associated with desegregation but rather suggests a tendency to stabilize, with declines in immigrant enrollments concentrated in schools with larger immigrant populations at the outset. The authors also find that changes in the immigrant shares influence the composition of the school's students, and that overall school demographic changes do not mirror grade-level changes within schools.
