We assess and apply the term-structure model introduced by Nelson and Siegel (1987) and re-interpreted by Diebold and Li (2003) as a modern three-factor model of level, slope and curvature. First, we ask whether the model is a member of the affine class, and we find that it is not. Hence the...

There is much confusion in the economics literature on wage determination and the employment–inflation trade-off. Few model builders pay as much careful attention to the definition and meaning of long-run concepts as did Albert Ando. Expanding on years of painstaking work by Ando, the...

The popular Nelson-Siegel (1987) yield curve is routinely fit to cross sections of intra-country bond yields, and Diebold and Li (2006) have recently proposed a dynamized version. In this paper we extend Diebold-Li to a global context, modeling a potentially large set of country yield curves in...
