Historical estimates of the informational content in the yield curve may no
t be relevant after a change in monetary policy. This study uses a small dy
namic rational expectations model with staggered price setting to study how
monetary policy affects the relation between nominal interest rates, infla
tion expectations, and real interest rates. The benchmark parameters, inclu
ding the Fed's loss function parameters, are estimated by maximum likelihoo
d on quarterly US data. The policy experiments include stronger inflation t
argeting and more active monetary policy. (C) 2001 Society for Policy Model
