This paper summarizes the microevidence on the setting of producer prices in the euro area. The main findings are: (i) 21% of producer prices are adjusted each month, (ii) producer prices are changed more frequently and by smaller amounts than consumer prices (even after controlling for product characteristics), (iii) price decreases are relatively frequent, (iv) inflation correlates positively with the difference between the frequency of price increases and decreases, and (v) there is substantial variation in price flexibility across sectors, which can be explained in part by differences in the cost structure, the degree of competition, and the level of sectoral inflation.
