Level, slope, curvature of the sovereign yield curve, and fiscal behaviour
Afonso, António; Martins, Manuel Mota Freitas - 2010
We study fiscal behaviour and the sovereign yield curve in the U.S. and Germany in the period 1981:I-2009:IV. The latent factors, level, slope and curvature, obtained with the Kalman filter, are used in a VAR with macro and fiscal variables, controlling for financial stress conditions. In the...
