A Portfolio-Balance Approach to the Nominal Term Structure
Explanations of why changes in the relative quantities of safe debt seem to affect asset prices often appeal informally to a ?portfolio balance? mechanism. I show how this type of effect can be incorporated in a general class of structural, arbitrage-free asset-pricing models using a numerical solution method that allows for a wide range of nonlinearities. I consider some applications in which the Treasury market is isolated, investors have mean-variance preferences, and the short-rate process is truncated at zero. Despite its simplicity, a version of this model incorporating inflation can ...
How the Federal Reserve's Large-Scale Asset Purchases (LSAPs) Influence Mortgage-Backed Securities (MBS) Yields and U.S. Mortgage Rates
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 expectations alone, suggesting that portfolio rebalancing effects of LSAPs are an important consideration for monetary policy transmission. Our estimates also suggest that the Federal Reserve must hold a substantial market share of agency MBS or of Treasury securities to significantly lower MBS yields ...
An agency problem in the MBS market and the solicited refinancing channel of large-scale asset purchases
In this paper, we document that mortgage-backed securities (MBS) held by the Federal Reserve exhibit faster principal prepayment rates than MBS held by the rest of the market. Next, we show that this stylized fact persists even when controlling for factors that affect prepayment behavior, and thus determine the MBS that are delivered to the Federal Reserve. After ruling out several potential explanations for this result, we provide evidence that points to an agency problem in the secondary market for MBS, which has not previously been documented, as the most likely explanation for the ...
