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. To that end, we estimate, at a very high level of disaggregation, competing-risks duration models that distinguish...

In general, empirical studies having evaluated with firm individual data the effects of structural labour market reforms in European countries do not reach unambiguous conclusions. In particular, they find that reforms increasing incentives to lower the number of temporary labour contracts do...

We use a French firm-level panel data set over the period 1993-2004 to analyze the relationship between credit constraints and firms' R&D behavior over the business cycle. Our main results can be summarized as follows: (i) the share of R&D investment over total investment is countercyclical...

This paper proposes a model in the spirit of Aghion et al. (2005) that encompasses the magnitude of the impact of competition on R&D according to the cost of the innovation. The effect of competition on R&D is an inverted U-shape. However, the shape is flatter and competition policy is therefore...

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...

We highlight different stylized facts concerning wage stickiness. First, in France, the typical duration of a wage agreement is one year. Consequently, a Taylor-type (1980) model appears to reproduce appropriately the distribution of agreement durations. Some 30 percent of settlements stipulate...
