Abstract

This article evaluates the relative performance of housing programs in terms of neighborhood quality. We profile neighborhood characteristics surrounding assisted housing units and assess the direction of assisted housing policy in light of this information. The analysis relies on a housing census database we developed that identifies the type and census tract location of assisted housing units—that is, public housing, developments assisted under the Department of Housing and Urban Development, the Section 515 Rural Rental Housing Direct Loan Program, the low‐income housing tax credit, certificates and vouchers, and state rental assistance programs.

We conclude that project‐based assistance programs do little to improve the quality of recipients’ neighborhoods relative to those of welfare households and, in the case of public housing, appear to make things significantly worse. The certificate and voucher programs, however, appear to reduce the probability that families will live in the most economically and socially distressed areas.  相似文献

Abstract

The Low‐Income Housing Tax Credit program has been operating for over 10 years and has helped finance thousands of developments with units set aside for low‐ or moderate‐income households. However, the program has been criticized for requiring additional layers of subsidy to leverage investment and for providing benefits to developers in excess of the amount necessary to induce them to invest.

An analysis of a sample of developments from Missouri finds that the tax credits are syndicated, with virtually all of the syndication proceeds (about 33 percent of the financing) used to pay for development costs. Conventional lending provides another 44 percent of the financing. Unfortunately, because these sources do not cover all of the costs, developers enter into a complex, costly process of layering additional subsidies, one on top of another, to fully finance the development.  相似文献

Abstract

The common wisdom is that assisted housing developments have both a direct and an indirect impact on concentrated poverty. The indirect effects are based on the notion that the negative stereotypes associated with such developments spill over into the surrounding neighborhoods, causing people who can leave to do so or avoid the neighborhood and leaving behind only the more disadvantaged segments of society. An increase in concentrated poverty in the neighborhood surrounding the development results. Prior studies, relying on aggregated data, are consistent with this thesis. The overwhelming majority of the statistical models in my study, however, found these relationships to be spurious. Once individual and macrolevel characteristics were controlled for, the relationships disappeared.

These findings imply that assisted housing developments will not typically contribute to concentration of poverty in surrounding neighborhoods and suggest that much of the negative reaction to assisted housing developments is unwarranted.  相似文献

Abstract

The article by Stegman, Davis, and Quercia is a careful, comprehensive analysis of the current impact of the Earned Income Tax Credit (EITC) on the housing cost burdens of working families. Its major proposal, a graduated supplement to the EITC to reflect housing costs, is compared with my broader concept of addressing severe cost burdens through supplements to major income support programs. Criticisms of my concept, chiefly administrative difficulties and incompatibility with the EITC benefit structure, are discussed.

My primary concerns are that Stegman, Davis, and Quercia's proposal does not sufficiently target families with severe housing costs and that the formula for calculating the additional benefit does not reflect diverse housing costs throughout the country and provides the smallest increases to the recipients with the lowest incomes. However, it is more important to generate discussion of the reality that “income policy IS housing policy” than to argue about details.  相似文献

车辆上脱落细胞STR检验   总被引:2,自引:1,他引:1

目的对汽车方向盘及变速杆把手上的皮肤脱落细胞进行STR检验研究。方法用EZ-tape采集车辆方向盘及变速杆上的脱落细胞,Chelex-100法与磁珠法结合提取DNA,延长保温时间。定量后调整PCR反应体系,适当增加PCR循环数,增加PCR产物量及延长进样时间进行电泳检测,使用GeneMapperIDV3.2软件进行STR分型。同时,对比使用多重置换扩增技术对提取的DNA进行全基因组扩增。结果对33份车辆方向盘和变速杆上脱落细胞的检测,其中19份检出全部基因座的基因分型结果,9份检出部分基因型,5份未检出DNA分型结果。而利用多重置换扩增技术未获得满意图谱。结论本研究建立的脱落细胞收集、DNA提取、PCR扩增及检测方法适合于车辆上脱落细胞的检验,其结果优于使用多重置换扩增技术获得的分型。  相似文献

刚刚通过的《中华人民共和国刑法修正案(七)》对于绑架罪进行了部分修正,增设了"情节较轻"的减轻构成规定,这虽然具有重要的意义,但是这一减轻构成的评价、理解与适用本身仍是问题。在对绑架罪的减轻构成从规定方式到下限选择作了评述之后,文章继而讨论了对于"情节较轻"的具体理解问题,特别指出在规定了绑架罪"情节较轻"的构成之后要避免的几种错误倾向。同时,修正案对于绑架罪的加重构成未作任何修改,这十分令人遗憾,而本着严格限制死刑适用的初衷,必须对于现有的加重构成进行严格的限制解释。总体而言,修正案对于绑架罪的修改虽有进步但不彻底,可谓是"半截子的革命"。  相似文献

Abstract

The Low‐Income Housing Tax Credit (housing credit) that Cummings and Di‐Pasquale portray is effective, efficient, and healthy. However, rapid changes in the industry have turned some of their data stale, and the absence of suitable context and information invalidate some key analyses and findings. Moreover, the researchers sometimes seem to see the glass as 10 percent empty instead of 90 percent full. A practitioners’ perspective is more positive.

The housing credit generates an array of public benefits while harnessing private investors’ business discipline. Genuinely low‐income tenants occupy the housing. The housing revitalizes low‐income communities. Properties are in good financial and physical condition. The housing credit is also cost effective. The economic fundamentals of producing low‐income rental housing, not the housing credit, necessitate substantial subsidies. A remarkably high proportion of the federal tax‐credit subsidy goes into the housing, and investor returns are modest. Nonprofit‐sponsored production appears to cost more because nonprofits are prominent in high‐cost locations and for other similar reasons, not because nonprofit developers are inefficient.  相似文献

Abstract

This article briefly reviews the origins of New Urbanism and its manifesto as emerging from the social change movements of the 1960s, which evolved out of ideas of a previous generation of American and European designers living through the rise of modern industrialization. Arising from the same turmoil of the 1960s, and parallel to the New Urbanists, evolved a more loosely affiliated network of progressive academic and practicing planners and architects who have aligned themselves with disenfranchised underclasses not benefiting from the wealth of the postwar era and who take direction not from a manifesto but from a body of thinking linked to a broader intellectual and political agenda. This group works primarily with grassroots organizations in lower‐income communities and intentionally stays out of the limelight to better serve its constituents. The article concludes with ideas for possible collaboration between these professional groups serving different ends of the socioeconomic spectrum.  相似文献
