This paper estimates an affine term structure model (ATSM) and a shadow rate model (SRM) using Japanese, US, and UK data until March 2013. These models produce very different results, which are attributable to the ATSM's neglect of the zero lower bound (ZLB). The 10-year term premium estimated by the ATSM occasionally deviates from that estimated by the SRM by around 2 percentage points, and the deviation has recently widened in the US and the UK. The ATSM consistently overestimates the long-run level of the short rate, which appears to contribute to the tendency to underestimate the term premium.
