Bond positions, expectations, and the yield curve
This paper implements a structural model of the yield curve with data on nominal positions and survey forecasts. Bond prices are characterized in terms of investors' current portfolio holdings as well as their subjective beliefs about future bond payoffs. Risk premia measured by an econometrician vary because of changes in investors' subjective risk premia that are identified from portfolios and subjective beliefs but also because subjective beliefs differ from those of the econometrician. The main result is that investors' systematic forecast errors are an important source of business cycle ...

How "unconventional" are large-scale asset purchases? The impact of monetary policy on asset prices
This paper examines the impact of large-scale asset purchases (LSAP) on U.S. asset prices (nominal and inflation-indexed bonds, stocks, and U.S. dollar spot exchange rates) using an event study with intraday data. The surprise component of LSAP announcements is identified from Financial Times articles. Estimation results show that the LSAP news has economically large and highly significant effects on asset prices, even after controlling for the surprise component of the Fed's conventional target rate decision and communication about its future path of policy. This study documents that the ...

Arbitrage-free bond pricing with dynamic macroeconomic models
The authors examine the relationship between changes in short-term interest rates induced by monetary policy and the yields on long-maturity default-free bonds. The volatility of the long end of the term structure and its relationship with monetary policy are puzzling from the perspective of simple structural macroeconomic models. The authors explore whether richer models of risk premiums, specifically stochastic volatility models combined with Epstein-Zin recursive utility, can account for such patterns. They study the properties of the yield curve when inflation is an exogenous process and ...

Restrictions on Risk Prices in Dynamic Term Structure Models
Restrictions on the risk-pricing in dynamic term structure models (DTSMs) tighten the link between cross-sectional and time-series variation of interest rates, and make absence of arbitrage useful for inference about expectations. This paper presents a new econometric framework for estimation of affine Gaussian DTSMs under restrictions on risk prices, which addresses the issues of a large model space and of model uncertainty using a Bayesian approach. A simulation study demonstrates the good performance of the proposed method. Data for U.S. Treasury yields calls for tight restrictions on risk ...

Modeling credit contagion via the updating of fragile beliefs
We propose a tractable equilibrium model for pricing defaultable bonds that are subject to contagion risk. Contagion arises because agents with ?fragile beliefs? are uncertain about both the underlying state of the economy and the posterior probabilities associated with these states. As such, agents adopt a robust decision rule for updating that leads them to over-weight the posterior probabilities of ?bad? states. We estimate the model using panel data on sovereign Euro-zone CDS spreads during the recent crisis, and find that it captures levels and dynamics of spreads better than traditional ...

Jump-diffusion processes and affine term structure models: additional closed-form approximate solutions, distributional assumptions for jumps, and parameter estimates
Affine term structure models in which the short rate follows a jump-diffusion process are difficult to solve, and the parameters of such models are hard to estimate. Without analytical answers to the partial difference differential equation (PDDE) for bond prices implied by jump-diffusion processes, one must find a numerical solution to the PDDE or exactly solve an approximate PDDE. Although the literature focuses on a single linearization technique to estimate the PDDE, this paper outlines alternative methods that seem to improve accuracy. Also, closed-form solutions, numerical estimates, ...
