Introduction to session 3: Estimating the costs: Perspectives on preservation of the nation's lower‐income housing stock

Abstract

This article uses survey data from the Moving to Opportunity demonstration program in Chicago to explore changes for households moving from public housing. The focus is on two key areas: housing and neighborhood conditions, and labor force participation and employment of householders. The experimental design of the program allows the differences between comparison households, which moved with a regular Section 8 voucher, and experimental households, which moved to low‐poverty neighborhoods with housing counseling assistance, to be examined.

The findings, based on interviews an average of 18 months after families moved, reveal dramatic improvements in neighborhood and housing conditions for all participating families; experimental families experienced even greater gains in terms of housing and especially neighborhood conditions. Labor force participation and employment increased for householders in both groups, likely fueled by the robust economy throughout much of the country and supporting similar findings for program participants in New York and Boston.     

Social capital and the revitalization of New York City's distressed inner‐city housing

Abstract

This article presents evidence that social capital can be an effective component of locally sponsored low‐income housing programs. It provides a model for measuring social capital at the building level, where it may be most effective in improving housing quality and security. The study compares five programs in New York City that house the city's poorest, mostly minority residents. The surveys from 487 buildings in Brooklyn, NY, were analyzed to compare the success of programs in maintaining and revitalizing landlord‐abandoned buildings taken by the city in lieu of taxes.

Results of the analysis demonstrate that the positive effects of tenant ownership were largely mediated by the higher levels of social capital found in these buildings. These levels have implications for the survival and economic advancement of poor households and civic participation in poor communities. The study suggests the value of alternative homeownership programs.     

Networks and nonprofits: Opportunities and challenges in an era of federal devolution

Abstract

Community development corporations and other nonprofit organizations are increasingly responsible for producing and managing low‐income housing in urban America. This article examines the network of governmental, philanthropic, educational, and other institutions that channel financial, technical, and political support to nonprofit housing sponsors. We analyze the relationships among these institutions and propose an explanation for their success. We then consider challenges the network must confront if the reinvention of federal housing policy is to succeed.

Block grants and rental vouchers, the dominant emphases of federal policy, present opportunities and constraints for nonprofit housing groups and their institutional networks. While states and municipalities are likely to continue to use block grants for nonprofit housing, the viability of this housing will be severely tested as project‐based operating subsidies are replaced by tenant‐based vouchers. We recommend ways that the federal, state, and local governments should help the institutional support network respond to this challenge.     

The cost‐effectiveness of the low‐income housing tax credit relative to vouchers: Evidence from six metropolitan areas

Abstract

How expensive is the Low‐Income Housing Tax Credit (LIHTC) program relative to vouchers? Are there any market conditions under which the supply‐based LIHTC could be more cost‐effective than demand‐based vouchers? This article examines these questions in six metropolitan areas—Boston, New York, San Jose (CA), Atlanta, Cleveland, and Miami. Controlling for family income and unit size, I compare the development subsidies of new‐construction LIHTC projects with the alternative 20‐year voucher cost in each area.

In general, the LIHTC is found to be more expensive than vouchers. The premium, however, varies significantly by voucher payment standard and local housing market. Assuming a payment standard of 100 percent of fair market rent, the LIHTC is only 2 percent more expensive than vouchers in San Jose, but more than twice as expensive as vouchers in Atlanta. Many factors account for these regional variations. This study emphasizes two: local market conditions and program administration.     

Racial/ethnic differences in housing outcomes for first‐time,low‐income home buyers: Findings from a National homeownership education program

Abstract

Federal housing policies aimed at making homeownership more accessible through education and affordable lending have been successful in raising the homeownership rate among minorities. By marketing homeownership to underserved populations and helping them overcome financial and informational obstacles, such programs might be expected to promote equality in housing outcomes, including housing quality, neighborhood composition, and neighborhood conditions, for minority homeowners.

This article examines the experience of participants in a national home‐ownership education program. While the transition to homeownership has been associated with modest progress, it does not overcome persistent disparities in housing quality. Homeownership appears to lead to poorer neighborhood conditions for all lower‐income buyers—not just minorities—and may be exacerbating social and spatial isolation rather than helping to overcome it. Differences in neighborhood outcomes, however, may be due to locational preference rather than discrimination in housing and mortgage markets.     

Direct comparison of post-28-cycle PCR purification and modified capillary electrophoresis methods with the 34-cycle “low copy number” (LCN) method for analysis of trace forensic DNA samples

The investigation of samples with low amounts of template DNA remains at the forefront of forensic DNA research and technology as it becomes increasingly important to gain DNA profile information from exceedingly trace levels of DNA. Previous studies have demonstrated that it is possible to obtain short tandem repeat (STR) profiles from <100 pg of template DNA by increasing the number of amplification cycles from 28 to 34, a modification often referred to as “low copy number” or LCN analysis. In this study, we have optimised post-PCR purification techniques applied after only 28 cycles of PCR, as well as using modified capillary electrophoresis injection conditions and have investigated the progressive application of these enhanced approaches. This paper reviews the characteristics of the profiles obtained by these methods compared with those obtained on the same samples after 34-cycle PCR. We observed comparable sensitivity to 34-cycle PCR in terms of the number of profiles with evidence of DNA and the number of allelic peaks per profile and we noted improved peak height and area magnitude with some sample types. Certain parameters reported to be adversely affected in 34-cycle LCN investigations, such as non-donor allele peaks and increased stutter peak ratio, were reduced by this approach. There are a number of advantages for trace samples in progressing from the standard 28-cycle process to the post-PCR processing method as compared to 34-cycle PCR method, including reduced sample consumption, reduced number of PCR amplifications required, and a staged approach to sample processing and profile interpretation.

Housing needs and effective policies in high‐tech metropolitan economies

Abstract

What are the most effective ways to provide low‐income housing to those left behind in new economy housing markets? Do winners and losers in high‐tech competition require federal housing strategies geared to metropolitan differences? This article examines 45 large metropolitan areas grouped along a high‐tech spectrum to see who is dis‐advantaged and to deduce effective local low‐income housing strategies from market characteristics.

Finding affordable housing was, on average, more difficult for low‐income renters and owners in high‐tech economies in the 1990s. Nonetheless, high‐tech metropolitan economies, like other local/regional markets, vary greatly. Sharp differences among and within metropolitan markets make it essential that federal strategies allow local policies to respond to local conditions. To most effectively provide low‐income housing to those left behind in all markets, federal policy should target sufficient resources to severe housing needs through many more vouchers and programs that permit and encourage effective local choices.     

2011年新加坡大选中工人党的竞选策略探析

在2011年国会大选中,新加坡工人党在保住后港单选区的基础上,在阿裕尼集选区击败外交部长杨荣文率领的人民行动党团队,共取得了6个议席。这是自新加坡1988年集选区制度实行以来,反对党第一次战胜人民行动党拿下集选区,也是1966年以来反对党取得议席最多的一次大选。这届大选被认为是新加坡的政治分水岭。工人党之所以能取得如此战绩,是由于它采取了正确的竞选策略：工人党整合人才资源,物色到了可媲美人民行动党的候选人;抓住转战时机,刘程强适时走出后港;提出了“第一世界国会”“副司机”等全国性课题;不为反对而反对,打造理智的建设性反对党形象;挟上届大选余威,综合考量历史、地理因素;准确把握竞选过程中的细节。
