Credit Rationing in the U.S. Mortgage Market: Evidence from Variation in FHA Market Shares
This paper examines the nature of mortgage credit rationing across geographic markets and time. Particular attention is paid to the response of conventional mortgage supply to higher risk conditions associated with regional recessions. We develop a series of four indirect tests based on the spatial variation of the FHA share of mortgages, both endorsements and applications, as well as FHA and conventional rejection rates. Results of these four tests indicate that conventional mortgage underwriting criteria do not become more flexible and may even become more demanding when local economic conditions deteriorate. This result indicates the use of non-price credit rationing in the mortgage market and suggests a special role for FHA-insured mortgages as a mechanism for maintaining mortgage credit supply in declining housing markets

Human activity was a major driver of the mid-Holocene vegetation change in southern Cumbria: Implications for the elm decline in the British Isles
This is the author accepted manuscript. The final version is available from Wiley via the DOI in this record.The dramatic decline in elm (Ulmus) across a large swathe of north-west Europe in the mid-Holocene has been ascribed to a number of possible factors, including climate change, human activity and/or pathogens. A major limitation for identifying the underlying cause(s) has been the limited number of high-resolution records with robust geochronological frameworks. Here, we report a multiproxy study of an upland (Blea Tarn) and lowland (Urswick Tarn) landscape in southern Cumbria (British Isles) to reconstruct vegetation change across the elm decline in an area with a rich and well-dated archaeological record to disentangle different possible controls. Here we find a two-stage decline in Ulmus taking place between 6350–6150 and 6050–5850 cal a BP, with the second phase coinciding with an intensification of human activity. The scale of the decline and associated human impact is more abrupt in the upland landscape. We consider it likely that a combination of human impact and disease drove the Ulmus decline within southern Cumbria.This work was funded by a studentship for MJG from the University of Exeter and Sir John Fisher Foundation.

State and Local Anti-Predatory Lending Laws: The Effect of Legal Enforcement Mechanisms
Subprime mortgage lending has grown rapidly in recent years and with it, so have concerns about predatory lending. In response to evidence of predatory lending, most states have enacted new laws or expanded existing laws to address abuses in the subprime home loan market. The effect of these statutes is a matter of debate. This paper seeks to improve the understanding of this increasingly important issue and pays particular attention to the role that legal enforcement mechanisms play in this context. The results of the analysis are consistent with the view that anti-predatory lending laws influence subprime lending markets and that disaggregating the details of the overall legal framework into its component parts is essential for understanding subprime market dynamics. The restrictions, coverage, and enforcement components all have significant relationships with subprime market outcomes, with the coverage relationship found to be broadly consistent with the reverse lemons hypothesis put forward by Ho and Pennington-Cross (2007). The results also suggest that the newer mini-HOEPA laws have had an impact on the subprime market above and beyond the older preexisting laws, particularly for subprime originations. Broader coverage through these new laws is associated with higher origination likelihoods, while increased restrictions through the mini-HOEPA laws are associated with lower origination propensities
The Impact of State Anti-Predatory Lending Laws: Policy Implications and Insights
The subprime mortgage market, which consists of high-cost loans designed for borrowers with weak credit, has grown tremendously over the past ten years. Between 1993 and 2005, the subprime market experienced an average annual growth rate of 26 percent. As this market emerged, so did allegations that subprime loans contained predatory features or were the result of predatory sales practices.3 In the worst cases, brokers deceived borrowers about the meaning of loan terms or falsely promised to assist them in obtaining future refinance loans with better terms. In other situations, borrowers entered into loans with low teaser rates, not aware how high their monthly payments could go when their interest rates reset
Location, correlation, radiation: where is the , what is its structure and what is its coupling to photons?
Scalar mesons are a key expression of the infrared regime of QCD. The
lightest of these is the . Now that its pole in the complex energy
plane has been precisely located, we can ask whether this state is transiently
or or a multi-meson molecule or largely glue? The
two photon decay of the can, in principle, discriminate between these
possibilities. We review here how the ,
cross-sections can be accurately computed. The result not only agrees with
experiment, but definitively fixes the radiative coupling of the . This
equates to a two photon width of keV, which accords with the
simple non-relativistic quark model expectation for a
scalar. Nevertheless, robust predictions from relativistic strong coupling QCD
are required for each of the possible compositions before we can be sure which
one really delivers the determined coupling.Comment: 18 pages, 11 figures. To be published in Modern Physics Letters A A

The dispersive contribution of decays and X(1576)
We study whether the broad enhancement X(1576) arises from the final state
interaction (FSI) of decays. We
consider both the absorptive and dispersive contribution of the above
amplitudes since the intermediate states are very close to .
The same mechanism leads to a similar enhancement around 1580 MeV in the
spectrum in the channel, which
can be used to test whether X(1576) can be ascribed to the FSI effect of
