Monetary Policy in the Presence of Asymmetric Wage Indexation

We study optimal monetary policy in the presence of asymmetric wage indexation. We findthatthe monetary authorities do not react to small output shocks, and that their reaction to large shocks is asymmetric, insofar as they absorb positive shocks more than negative ones. As a consequence, we observe that asymmetric wage indexation can be contractionary. It has ambiguous effects on expected inflation and welfare relative to an equivalent symmetric indexation. Optimal symmetric inflation, however, always outperforms optimal asymmetric indexation.
