Empirical and institutional evidence finds considerable time variation in the degree of wage indexation to past inflation, a finding that is at odds with the assumption of constant indexation parameters in most New-Keynesian DSGE models. We build a DSGE model with endogenous wage indexation in...

Wage indexation practices have changed. Evidence on the U.S. for instance suggests that wages were heavily indexed to past inflation during the Great Inflation but not during the Great Moderation. However, most DSGE models assume fixed indexation parameters in wage setting, which might not be...

This paper provides quantitative estimates of the welfare costs of nominal wage contracts. We find that the welfare costs of such contracts are fairly small and are generally relatively insensitive to changes in the economic environment. We then study how contract length might respond to changes...
