“…Many studies have been conducted on yield curve models and on the subclass of affine term structure models. Among them, the following works are most relevant to this paper: Ang and Piazzesi (2003), Ang, Dong, and Piazzesi (2007), Bikbov and Chernov (2006), , Dewacher, Lyrio, and Maes (2006), Duffee (2006Duffee ( , 2007, Vestin (2006, 2007), and Wu (2004, 2007) all of which include macro factors as well as latent factors in their "macro-finance" affine term structure models. Kim (2007), meanwhile, discusses various challenges in the specification and implementation of "macro-finance" models.…”
