This paper presents a present-biased general equilibrium model that explains many features of bond behavior. Present-biased investors increase (decrease) short-term (long-term) hedge demands compared to standard preferences. Hence, present bias drives up (down) short-term bond prices (yields)...

We propose a new time-varying Generalized Dynamic Factor Model for high-dimensional, locally stationary time series. Estimation is based on dynamic principal component analysis jointly with singular VAR estimation, and extends to the locally stationary case the one-sided estimation method...
