We empirically examine the role of appraisal in the residential mortgage lending process—in particular, the incidence, consequences, and determinants of appraisal below contract purchase price. Using the Boston Federal Reserve Study data set, we find that, as expected, low appraised value significantly increases the probability of mortgage loan application rejection. We find no evidence that low appraised value is related to census tract racial composition, an important finding given the history of the appraisal industry; however, low appraised value is related to proxies for neighborhood quality. Moreover, properties securing adjustable rate mortgages, condominiums, and properties purchased by African American buyers show an increased probability of low appraisal, though the race effect result is highly sensitive to model specification.  相似文献

A gigantic urban revolution is under way today: in 40 years, the equivalent of 1000 cities, each of three million inhabitants, will have to be built. In 2005, half of the world's population will live in cities. This growth will be concentrated in major cities, most of them in the South. This article reviews some fundamental trends, challenges and possible solutions in environment-related fields such as water, transports, energy. It argues for the emergence of a new urban culture based on the adoption of sustainable urban consumption patterns, new urban partnerships and the strengthening of urban solidarities. It gives examples of practical solutions within our reach for humanizing cities in the 21st century.  相似文献

The “Great Recession” in the United States exposed contradictions between the economic well‐being of families and capital that developed in the decades prior to this latest downturn. Using social structure of accumulation theory, a qualitative institutional analysis, and quantitative time‐series models, this article investigates historically contingent relations between the nature of public assistance, family economic deterioration, and capital accumulation. To sustain the circuit of capital, I argue that the family propped up economic growth first through public cash assistance and then through private expenditures, the latter of which lead to the economic deterioration of families dependent on unprecedented levels of debt.  相似文献

The study presents a framework for the analysis of advertising in digital games. It reviews literature on in-game advertising, advergames and advertising in social network games. The framework distinguishes between stimulus characteristics of the game as well as of the advertising that lead to psychological responses toward the game and the brand and to actual behavior toward the game and the brand. It takes into consideration individual factors of the player and social factors surrounding the player. In addition, theoretical models of advertising perception in digital games and issues regarding regulation are addressed. Directions for future research in the area of advertising in digital games are provided.  相似文献

Explicitly incorporating current distributional concerns into the safe minimum standard (SMS) approach is the objective of this study. The SMS approach is a collective choice process that prescribes protecting a minimum level of a renewable natural resource unless the social costs of doing so are somehow excessive or intolerably high. More complete implementation of an SMS approach, if it is to be a pragmatic policy tool, requires that distributional considerations be included in determining whether the economic consequences of preservation actions are intolerable. Two case studies involving the US Endangered Species Act are used to illustrate how distributional concerns might be incorporated into the SMS approach.  相似文献

Drawing on extensive academic research concerning clusters and networks, this paper seeks to create a framework capable of reviewing and monitoring different aspects of clusters and networks on an ongoing basis. The nine-element framework allows evaluation of the structures and processes for the eight basic cluster types identified from the literature. The use of this framework as a complimentary tool to the Multi-sectoral Qualitative Analysis (MSQA) methodology is then demonstrated using three examples (the construction, hardwood timber and higher education sectors). The data was gathered from three sets of key stakeholders (government, institutions and industry) provided from a recent study funded by the Welsh Assembly Government's Small Grants Research Programme. These cases illustrate the use of the framework in helping to generate the initial information necessary for subsequent cluster development policy (within overall regional economic development) by government to occur. The framework provides tools for reviewing and monitoring individual sectors. Information captured within the framework can also help in ameliorating problems in sectors likely to decline further. The need for further development research is also identified. Specifically at the level of the firm and network, there is a need to generate a more detailed framework of analysis of factors that contribute to successful processes of network management, learning and innovation, from which more detailed policy could be enacted in future.  相似文献
