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...
