This paper analyses two reasons why inflation may interfere with price adjustment so as to create inefficiencies in resource allocation at low rates of inflation. The first argument is that the higher the rate of inflation the lower the likelihood that downward nominal rigidities are binding...

I construct a novel measure of household uncertainty based on survey data for European countries. I show that household uncertainty shocks are not universally like negative demand shocks. Notably, household uncertainty shocks are largely inflationary in Europe. These results lend support to a...

We argue that the New-Keynesian Phillips Curve literature has failed to deliver a convincing measure of “fundamental inflation”. We start from a careful modeling of optimal price setting allowing for non-unitary factor substitution, non-neutral technical change and timevarying factor...

Inflation may enhance the efficiency of the price system in the presence of nominal rigidities. For the price system to function efficiently there is a need for nominal prices to adjust both to real and nominal shocks for relative prices to disseminate the appropriate signals. Since the...

We estimate a multi-country multi-sector New Keynesian model to quantify the drivers of domestic inflation during 2020–2023 in several countries, including the United States. The model matches observed inflation together with sector-level prices and wages. We further measure the relative...
