Density selection and combination under model ambiguity: an application to stock returns
This paper proposes a method for predicting the probability density of a variable of interest in the presence of model ambiguity. In the first step, each candidate parametric model is estimated minimizing the Kullback-Leibler 'distance' (KLD) from a reference nonparametric density estimate. Given that the KLD represents a measure of uncertainty about the true structure, in the second step, its information content is used to rank and combine the estimated models. The paper shows that the KLD between the nonparametric and the parametric density estimates is asymptotically normally distributed. ...

The scarcity value of Treasury collateral: Repo market effects of security-specific supply and demand factors
In the special collateral repo market, forward agreements are security-specific, which may magnify demand and supply effects. We quantify the scarcity value of Treasury collateral by estimating the impact of security-specific demand and supply factors on the repo rates of all outstanding U.S. Treasury securities. We find an economically and statistically significant scarcity premium. This scarcity effect is quite persistent, passes through to Treasury market prices, and explains a significant portion of the flow-effects of LSAP programs, providing additional evidence for the scarcity channel ...

Duration risk versus local supply channel in Treasury yields: evidence from the Federal Reserve's asset purchase announcements
The FOMC's announcements of Treasury purchase programs and the subsequent or contemporaneous statements by the New York Fed about the programs' operational details provide a sequence of natural experiments with the potential to shed light on the relative importance of the duration risk channel versus the local supply channel for the transmission of supply effects to the term structure of interest rates. Using intraday security-level data on Treasury securities, we conduct five event studies to document the presence of local supply effects and duration risk effects. Further, using our new ...

Tips from TIPS: the informational content of Treasury Inflation-Protected Security prices
Treasury Inflation-Protected Securities (TIPS) are frequently thought of as risk-free real bonds. Using no-arbitrage term structure models, we show that TIPS yields exceeded risk-free real yields by as much as 100 basis points when TIPS were first issued and up to 300 basis points during the recent financial crisis. This spread reflects predominantly the poorer liquidity of TIPS relative to nominal Treasury securities. Other factors, including the indexation lag and the embedded deflation protection in TIPS, play a much smaller role. Ignoring this spread also significantly distorts the ...

Flow and stock effects of large-scale asset purchases: evidence on the importance of local supply
The Federal Reserve's 2009 program to purchase $300 billion of U.S. Treasury securities represented an unprecedented intervention in the Treasury market and provides a natural experiment with the potential to shed light on the price elasticities of Treasuries and theories of supply effects in the term structure. Using security-level data on Treasury prices and quantities during the course of this program, we document a `local supply' effect in the yield curve?yields within a particular maturity sector responded more to changes in the amounts outstanding in that sector than to similar changes ...

The Federal Reserve's large-scale asset purchase programs: rationale and effects
We provide empirical estimates of the effect of large-scale asset purchase (LSAP)-style operations on longer-term U.S. Treasury yields within a framework that nests the alternative theoretical perspectives on LSAPs. As the principal channels through which LSAPs might matter for longer-term interest rates, we concentrate on (i) the scarcity (available local supply) channel associated with the traditional preferred habitat literature, and (ii) the duration channel associated with the general notion of interest rate risk. We also clarify LSAPs' role in the broader context of monetary policy ...

Flow and stock effects of large-scale Treasury purchases
Using a panel of daily CUSIP-level data, we study the effects of the Federal Reserve's program to purchase $300 billion of U.S. Treasury coupon securities announced and implemented during 2009. This program represented an unprecedented intervention in the Treasury market and thus allows us to shed light on the price elasticities and substitutability of Treasuries, preferred-habitat theories of the term structure, and the ability of large-scale asset purchases to reduce overall yields and improve market functioning. We find that each purchase operation, on average, caused a decline in yields ...

Tips from TIPS: the informational content of Treasury Inflation-Protected Security prices
We examine the informational content of TIPS yields from the viewpoint of a general 3-factor no-arbitrage term structure model of inflation and interest rates. Our empirical results indicate that TIPS yields contained a "liquidity premium" that was until recently quite large (~ 1%). Key features of this premium are difficult to account for in a rational pricing framework, suggesting that TIPS may not have been priced efficiently in its early years. Besides the liquidity premium, a time-varying inflation risk premium complicates the interpretation of the TIPS breakeven inflation rate (the ...

Uncertainty and disagreement in economic forecasting
Using the probabilistic responses from the Survey of Professional Forecasters, we study the evolution of uncertainty and disagreement associated with inflation forecasts in the United States since 1968. We compare and contrast alternative measures summarizing the distributions of mean forecasts and forecast uncertainty across individuals at an approximate one-year-ahead horizon. In light of the heterogeneity in individual uncertainty reflected in the survey responses, we provide quarterly estimates for both average uncertainty and disagreement regarding uncertainty. We propose direct ...

Tips from TIPS: the informational content of Treasury Inflation-Protected Security prices
TIPS breakeven inflation rate, defined as the difference between nominal and TIPS yields of comparable maturities, is potentially useful as a real-time measure of market inflation expectations. In this paper, we provide evidence that a fairly large TIPS liquidity premium existed until recently, using a multifactor no-arbitrage term structure model estimated with nominal and TIPS yields, inflation and survey forecasts of interest rates. Ignoring the TIPS liquidity premiums leads to counterintuitive implications for inflation expectations and inflation risk premium, and produces large pricing ...
