W. Letterie, BETTER MONETARY CONTROL MAY DECREASE THE DISTORTION OF STABILIZATION POLICY - A COMMENT, The Scandinavian journal of economics, 99(3), 1997, pp. 463-470
Higher uncertainty about the effects of policy instruments reduces a p
olicymaker's inclination to actively engage in shaping economic policy
. If a credibility problem exists, then this is beneficial. However, i
n the case where the policymaker has private information about an econ
omic shock, higher uncertainty is costly. Hence, the policymaker faces
a trade-off when he decides on the degree of control of monetary inst
ruments. It is shown that the optimal degree of uncertainty about the
effects of policy depends on the economic preferences of the policymak
er and the magnitude of the variance of the shock which is private inf
ormation.
