The mortgage rate conundrum
We document the emergence of a disconnect between mortgage and Treasury interest rates in the summer of 2003. Following the end of the Federal Reserve?s expansionary cycle in June 2003, mortgage rates failed to rise according to their historical relationship with Treasury yields, leading to significantly and persistently easier mortgage credit conditions. We uncover this phenomenon by analyzing a large data set with millions of loan-level observations, which allows us to control for the impact of varying loan, borrower, and geographic characteristics. These detailed data also reveal that ...

Villains or Scapegoats? The Role of Subprime Borrowers in Driving the U.S. Housing Boom
An expansion in mortgage credit to subprime borrowers is widely believed to have been a principal driver of the 2002?06 U.S. house price boom. Contrary to this belief, we show that the house price and subprime booms occurred in different places. Counties with the largest home price appreciation between 2002 and 2006 had the largest declines in the share of purchase mortgages to subprime borrowers. We also document that the expansion in speculative mortgage products and underwriting fraud was not concentrated among subprime borrowers.

Second Home Buyers and the Housing Boom and Bust
Record-high second home buying (homeowners acquiring nonprimary residences) was a central feature of the 2000s boom, but the macroeconomic effects remain an open question partly because reliable geographic data is currently unavailable. This paper constructs local data on second home buying by merging credit bureau data with mortgage servicing records. The identification strategy exploits the fact that the vacation share of housing from the 2000 Census is predictive of second home origination shares during the boom years, while also uncorrelated with other boom-bust drivers including proxies ...
