This paper documents the patterns and determinants of price setting in the Belgian industry. We analyse the micro data underlying the Producer Price Index (PPI) over the period from February 2001 to January 2005. On average only one out of four prices changes in a typical month, whereas the...

In this paper we analyse the Finnish consumer price changes from February 1997 to December 2004 on the basis of a set of microdata which covers over half of the items included in the Finnish CPI. Our findings can be summarised with four stylised facts. Firstly, only a small fraction of prices...

We characterize optimal state-dependent pricing rules under various forms of infrequent information. In all models, infrequent price changes arise from the existence of a lump-sum 'menu cost.' We entertain various alternatives for the source and nature of infrequent information. In two benchmark...

If firm pricing is state, rather than time-dependent, firms are more likely to change prices whenever aggregate and idiosyncratic shocks reinforce each other and trigger desired price changes in the same direction. The distribution of idiosyncratic shocks across adjusting firms therefore varies...

This paper proposes a model in which retail prices are sticky even though firms can always change their prices at zero cost. Instead of imposing a "menu cost", we assume that more precise decisions are more costly. In equilibrium, firms optimally make some errors in price-setting, thus...

This paper studies optimal monetary policy from the timeless perspective in a general model of state-dependent pricing. Firms are modeled as monopolistic competitors subject to idiosyncratic menu cost shocks. We find that, under certain conditions, a policy of zero inflation is optimal both in...

How do frictions in price setting influence monetary non-neutrality? We revisit this classic question in a quantitative menu cost model with multi-product firms that face idiosyncratic shocks with unsynchronized stochastic volatility. The model matches the unconditional distribution of price...

State-dependent and time-dependent price setting models yield distinct implications for how frequency and magnitude of price changes react to shocks. This note studies pricing behavior in Brazil following the large devaluation of the Brazilian Real in 1999 to distinguish between models. The...

This paper examines the role of habit formation in a standard state-dependent pricing (SDP) model. Incorporating habit formation helps the SDP model to generate hump-shaped and more persistent output responses under a monetary shock. More importantly, incorporating habit formation causes...

This paper investigates the price-setting behavior in Japan by using the CPI micro data in the Retail Price Survey from 1989 to 2003. We establish the four facts as follows. First, the frequency of price changes for goods is high while that for services is low. The frequency of price changes for...
