We investigate whether religion acts as a deterrent to the types of mortgage misrepresentation that played a significant role in the recent housing boom and bust. Using a large sample of mortgages originated from 2000 to 2007, we provide evidence that local religious adherence is associated with a lower likelihood of home appraisal overstatement and owner occupancy misreporting. The evidence on borrower income misrepresentation is mixed. Religiosity does not appear to reduce the incidence of income misrepresentation; however, it seems to (...) restrain the degree to which income is misrepresented. Our results are generally consistent with the hypothesis that religion, as a set of social norms, fosters ethical behavior, and possibly risk aversion, in the mortgage market. (shrink)
