Abstract: | This paper offers a preliminary evaluation of ECB conduct ofmonetary policy by estimating a fairly general reaction functionfor the euro area. The specification of the policy rule embodiesa number of nonlinearities which are shown to stem from asymmetricpreferences and a convex aggregate supply curve. Asymmetricpreferences allow, but do not require, policy-makers to weightdifferently positive and negative deviations of inflation andoutput from the reference values, and translate into an asymmetricreaction function. The empirical analysis on monthly euro-areaaggregated data over the last 5 years reveals that ECB monetarypolicy is effectively described by a nonlinear policy rule accordingto which output contractions have required a larger policy responsethan output expansions. Moreover, actual movements in the eurointerest rate closely resemble the simulated path that a Bundesbank-typeof behaviour would have implied. |
