Standard approaches to building and estimating dynamic term structure models rely on the assumption that yields can serve as the factors. However, the assumption is neither theoretically necessary nor empirically supported. This paper documents that almost half of the variation in bond risk...

No-arbitrage term structure models impose cross-sectional restrictions among yields and can be used to impose dynamic restrictions on risk compensation. This paper evaluates the importance of these restrictions when using the term structure to forecast future bond yields. It concludes that no...

Conditional maximum Sharpe ratios implied by fully flexible four-factor and five-factor Gaussian term structure models are astronomically high. Estimation of term structure models subject to a constraint on their Sharpe ratios uncovers properties that hold for a wide range of Sharpe ratios....
