This paper provides evidence that learning about demand is an important driver of firms' dynamics. We present a simple model with Bayesian learning in which firms are uncertain about their idiosyncratic demand parameter in each of the markets they serve, and update their beliefs as noisy...

Using millions of individual gasoline prices collected at a daily frequency, we examine the speed at which market refined oil prices are transmitted to consumer liquid fuel prices. We find that on average gasoline prices are modified once a week and the distribution of price changes displays a...

Using micro price data covering the Great Recession period, we document new facts on price rigidity in France: (i) each month, 17% of prices are changed versus 23% in the United States. When sales are excluded, only 14% of prices are modified in France versus 15% in the United States; (ii) the...

This paper provides some new empirical features on price setting behaviour for French producers using micro data underlying the producer and business-services price indices over the period 1994-2005. Some crucial methodological issues on the collection of producer prices are raised. Then, the...

Based upon a large fraction of the price records used for computing the French CPI, we document consumer price rigidity in France. We first provide a methodological discussion of issues involved in estimating average price duration with micro-data. The average duration of prices in the sectors...

This paper reports the results of a survey conducted by the Banque de France during winter 2003-2004 to investigate the price-setting behavior of French manufacturing companies. Prices are found to adjust infrequently; the median firm modifies its price only once a year. Price reviews are more...

. A recent strand of empirical work uses (S; s) models with time-varying stochastic bands to describe infrequent adjustments of prices and other variables. The present paper examines some properties of this model, which encompasses most micro-founded adjustment rules rationalizing infrequent...

Studies of firm-level data have shown that there is a huge dispersion of productivity across firms even when industries are narrowly defined. So there is a significant opportunity for the least productive firms to catch up to the most productive. The formers’ convergence could 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...

This paper proposes a two-regime Bounce-Back Function augmented Self-Exciting Threshold AutoRegression (SETAR) which allows for various shapes of recoveries from the recession regime. It relies on the bounce-back effects first analyzed in a Markov-Switching setup by Kim, Morley and Piger [2005]...
