This paper examines heterogeneity in price stickiness using a large, original, set of individual price data collected at the retail level for the computation of the French CPI. For that purpose, we estimate at a very high level of disaggregation competing-risks duration models that distinguish...

We document the presence of both small and large price changes in individual price records from the CPI in France and the US. After correcting for measurement error and cross-section heterogeneity we find that the size distribution of price changes has a positive excess kurtosis, with a shape...

We examine the effect of the minimum wage on restaurant prices. For that purpose, we estimate a price rigidity model by exploiting a unique dataset of individual price quotes used to calculate the Consumer Price Index in France. We find a positive and significant impact of the minimum wage on...
