In the past 10 years, increasingly sophisticated statistical techniques have been applied to the estimation of increasingly complex models of the term structure of interest rates. In reviewing this literature, we highlight the facts that have been established and the key unresolved issues. The...

Virtually all existing continuous-time, single-factor term structure models are based on a short rate process that has a linear drift function. However, there is no strong a priori argument in favor of linearity, and Stanton (1997) and Ait-Sahalia (1996), employing nonparametric estimation...

The dynamics of the unobservable quot;shortquot; or quot;instantaneousquot; rate of interest are frequently estimated using a proxy. We show how the biases resulting from this practice (the quot;proxy problemquot;) are related to the derivatives of the proxy with respect to the short rate and...

The dynamics of the unobservable short rate are frequently estimated directly using a proxy. We examine the biases resulting from this practice (the quot;proxy problemquot;). Analytic results show that the proxy problem is not economically significant for single-factor affine models. In the...
