A number of studies have estimated reaction functions focusing solely
on economic state variables such as inflation and unemployment. Other
reaction function studies have focused on political measures as regres
sors. In this study we include both sets of variables to see if politi
cal measures are significant when we control for economic state variab
les. Reaction functions are estimated for the 1959-91 period and for s
ubperiods corresponding to the tenures of different Federal Reserve Bo
ard chairmen. We find significant effects for a measure of political i
nfluence on the Federal Reserve for the whole period and some subperio
ds.
