Wage Indexation and the Monetary Policy Regime

We estimate a New Keynesian wage Phillips curve for a panel of 24 OECD countries, and allow the degree of wage indexation to past inflation to vary according to the monetary policy regime. We find that the extent of wage indexation is significantly lower in an inflation targeting regime, in contrast to monetary targeting, exchange rate targeting and policy regimes without an explicit quantitative anchor. The results put into question whether embedding a constant degree of wage indexation in standard DSGE models is truly structural.
