How much does quality adjustment matter in measuring consumer price inflation? To address this question, we use different sources of micro and macro price data for Germany and the euro area. For Germany, we find that quality adjustment applies to a large range of goods and services but, on...

This paper studies the pass-through from wages to producer prices using sectoral disaggregated data for the euro area. We find a positive and statistically significant wage-price pass-through that reaches 50% after three years, which differs across sectors. The wage-price pass-through in private...

We study how millions of granular and weekly household scanner data combined with machine learning can help to improve the real-time nowcast of German inflation. Our nowcasting exercise targets three hierarchy levels of inflation: individual products, product groups, and headline inflation. At...

The response of US inflation to the high levels of spare capacity during the Great Recession of 2007-09 was rather muted. At the same time, it has been argued that the short-term unemployment gap has a more prominent role in determining inflation, and either the closing of this gap or...

This paper studies the nature, evolution, and sources of inflation heterogeneity across households in France and Germany. Inflation differences are large and persistent. The two main sources of inflation heterogeneity are spatial differences in the prices paid for the same product and...

It has been widely documented that households experience different inflation rates which are generally concealed in aggregate price indices. Using scanner data from a large household panel for Austria, we analyse price dynamics faced by individual households and try to explain the causes for the...

We ask why, in many circumstances and many environments, decision-makers choose to act on a time-regular basis (e.g. adjust every six weeks) or on a stateregular basis (e.g. set prices ending in a 9), even though such an approach appears suboptimal. The paper attributes regular behaviour to...

In most OECD countries, we cannot reject up to three breaks in the mean of inflation: one break in the late 1960's-early 1970's, one in the early-mid 1980's and another break in the early 1990's. These breaks tend to be associated more often to breaks in the mean of nominal variables than to the...

This paper uses disaggregated CPI time series to show that a break in the mean of French inflation occurred in the mid-eighties and that the 1983 monetary policy shift mostly accounted for it. CPI average yearly growth declined from nearly 11% before the break date (May 1985) to 2.1% after. No...
