We document two stylised facts of US short- and long-term interest rate data incompatible with the pure expectations hypothesis: Relatively slow adjustment to long-run relations and low contemporaneous correlation. We construct a small structural model which features three types of randomness:...

The expectations hypothesis of the term structure (EHT) implies cointegration between interest rates of different maturities and predicts certain values for adjustment speed. We estimate reduced-form vector error correction models of the US term structure. These are derived from a structural...
