Mortgage Default Rates and Borrower Race
We estimate a mortgage default model with national data on conventional mortgages that were current from 1986 to 1992. Our analysis confirms the results of previous analyses of Federal Housing Authority mortgages: Black households have higher marginal default rates, controlling for differences in borrower and property characteristics. Further, we do not find that Black borrowers have significantly more home equity. These results do not provide evidence of racial discrimination in mortgage lending and suggest that differences in default costs or transaction costs may explain differences in default rates.
The topology of deformation spaces of Kleinian groups
Let M be a compact, hyperbolizable 3-manifold with nonempty incompressible
boundary and let AH(\pi_1(M)) denote the space of (conjugacy classes of)
discrete faithful representations of \pi_1(M) into PSL 2 (C). The components of
the interior MP(\pi_1(M)) of AH(\pi_1(M)) (as a subset of the appropriate
representation variety) are enumerated by the space A(M) of marked
homeomorphism types of oriented, compact, irreducible 3-manifolds homotopy
equivalent to M. In this paper, we give a topological enumeration of the
components of the closure of MP(\pi_1(M)) and hence a conjectural topological
enumeration of the components of AH(\pi_1(M)). We do so by characterizing
exactly which changes of marked homeomorphism type can occur in the algebraic
limit of a sequence of isomorphic freely indecomposable Kleinian groups. We use
this enumeration to exhibit manifolds M for which AH(\pi_1(M)) has infinitely
many components.Comment: 49 pages, published versio
Improving the chances for developing coastal country success in adapting to climate change
There is an unequivocal scientific consensus that increases in greenhouse gases in the atmosphere drive warming
temperatures of air and sea, and acidification of the worldâs oceans from carbon dioxide absorbed by the oceans.
These changes in turn can induce shifts in precipitation patterns, sea level rise, and more frequent and severe
extreme weather events (e.g. storms and sea surge). All of these impacts are already being witnessed in the worldâs
coastal regions and are projected to intensify in years to come. Taken together, these impacts are likely to result in
significant alteration of natural habitats and coastal ecosystems, and increased coastal hazards in low-lying areas. They can affect fishers, coastal communities and resource users, recreation and tourism, and coastal infrastructure. Approaches to planned adaptation to these impacts can be drawn from the lessons and good practices from global experience in Integrated Coastal Management (ICM). The recently published USAID Guidebook on Adapting to
Coastal Climate Change (USAID 2009) is directed at practitioners, development planners, and coastal management
professionals in developing countries. It offers approaches for assessing vulnerability to climate change and climate
variability in communities and outlines how to develop and implement adaptation measures at the local and national
levels. Six best practices for coastal adaptation are featured in the USAID Guidebook on Adapting to Coastal
Climate Change and summarized in the following sections. (PDF contains 3 pages
Convicts and coolies : rethinking indentured labour in the nineteenth century
This article seeks to shift the frame of analysis within which discussions of Indian indentured migration take place. It argues that colonial discourses and practices of indenture are best understood not with regard to the common historiographical framework of whether it was 'a new system of slavery', but in the context of colonial innovations in incarceration and confinement. The article shows how Indian experiences of and knowledge about transportation overseas to penal settlements informed in important ways both their own understandings and representations of migration and the colonial practices associated with the recruitment of indentured labour. In detailing the connections between two supposedly different labour regimes, it thus brings a further layer of complexity to debates around their supposed distinctions
