This paper shows that price rigidity evolves in an economy populated by imperfectly rational agents who experiment with alternative rules of thumb. In the model, firms must set their prices in face of aggregate demand shocks. Their payoff depends on the level of aggregate demand, as well as on...

We estimate the effects of monetary policy on price-setting behavior in administrative micro data underlying the German producer price index. After expansionary monetary policy, the increase in the frequency of price change is economically small, the average absolute size across all price...

We estimate the effects of monetary policy on price-setting behavior in administrative micro data underlying the German producer price index. We find a strong degree of monetary nonneutrality. After expansionary monetary policy, the mass of additional price adjustments is economically small and...

We develop a New Keynesian (NK) model with endogenous price setting frequency. Whether a firm updates its price in a given period depends on an analysis of expected cost and benefits modelled by a discrete choice process. A firm decides to update the price when expected benefits outweigh...

This paper provides a summary of current knowledge on inflation persistence and price stickiness in the euro area, based on research findings that have been produced in the context of the Inflation Persistence Network. The main findings are: i) Under the current monetary policy regime, the...
