We employ empirical pricing models for mortgage-backed security (MBS) yields and for mortgage rates to measure deviations from normal market functioning in order to assess how the Federal Reserve MBS purchase program -- a 16 month program announced on November 25, 2008 and completed on March 31,...

Mortgage securitization has been tried several times in the United States and each time it has failed amid a credit bust. In what is now a familiar recurring history, during the credit boom, underwriting standards are violated and guarantees are inadequately funded; subsequently, defaults increase...

The bank lending channel of monetary policy suggests that banks play a special role in the transmission of monetary policy. We look for this special role by examining the business strategies of banks as it relates to mortgage funding and mortgage lending. "Traditional banks" have a large supply...

We provide an empirical analysis of the effects of the Federal Reserve's asset holdings on MBS yields and mortgage rates. We argue that understanding the particulars of the U.S. mortgage markets, particularly the linkages between the secondary and primary mortgage markets, is important. We find...

We conduct an empirical analysis of the Federal Reserve's large-scale asset purchases (LSAPs) on MBS yields and mortgage rates. The Federal Reserve's accumulation of MBS and Treasury securities lowered MBS yields and mortgage rates by more than what would have been suggested by changes in market...

We construct a model of a bank's optimal funding choice, where the bank negotiates with both safety-driven short-term bondholders and (mostly) risk-taking long-term bondholders. We establish that investor demands for safety create a negative relationship between the bank's capital choices and...

The 30-year fixed-rate fully amortizing mortgage (or "traditional fixed-rate mortgage") was a substantial innovation when first developed during the Great Depression. However, it has three major flaws. First, because homeowner equity accumulates slowly during the first decade, homeowners are...

Fannie Mae and Freddie Mac are government-sponsored enterprises (GSEs) that purchase mortgages and issue mortgage-backed securities (MBS). In addition, the GSEs are active participants in the primary and secondary mortgage markets on behalf of their own portfolios of MBS. Because these...

The 30-year fixed-rate fully amortizing mortgage (or "traditional fixed-rate mortgage") was a substantial innovation when first developed during the Great Depression. However, it has three major flaws. First, because homeowner equity accumulates slowly during the first decade, homeowners are...

We provide evidence that a bank's subordinated debt yield spread is not, by itself, a sufficient measure of default risk. We use a model in which subordinated debt is held by investors with superior knowledge (informed investor hypothesis). First, we show that in theory the yield spread on...
