This paper explores time variation in the dynamic effects of technology shocks on U.S. output, prices, interest rates as well as real and nominal wages. The results indicate considerable time variation in U.S. wage dynamics that can be linked to the monetary policy regime. Before and after the...

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...

For a panel of 75 countries, we find that increases in global agricultural commodity prices that are caused by unfavorable harvest shocks in other regions of the world significantly curtail domestic economic activity. The effects are much larger than for average global agricultural price shifts....

I find that the Eurosystem can stimulate the economy beyond the policy rate by increasing the size of its balance sheet or the monetary base, that is so-called quantitative easing. The transmission mechanism turns out to be different compared to traditional interest rate innovations: whilst the...

We compare the economic consequences of several types of oil shocks across a set of industrialized countries that are structurally very diverse with respect to the role of oil and other forms of energy in their economy. We find considerably different effects across countries, which crucially...
