This paper presents a model in which price setting firms decide what to pay attention to, subject to a constraint on information flow. When diosyncratic conditions are more variable or more important than aggregate conditions, firms pay more attention to idiosyncratic conditions than to...

This paper compares the welfare implications of two widely used pricing assumptions in the New-Keynesian literature: Calvo-pricing vs. Rotemberg-pricing. We show that despite the strong similarities between the two assumptions to a first order of approximation, in general they might entail...

We implement a tractable state-dependent Calvo price-setting signal dependent on inflation and aggregate competitiveness. This allows us to derive a New Keynesian Phillips Curve (NKPC) expressed in terms of the actual levels of variables - rather than in-deviation from steady stateʺ form - and...

Using data on product-level prices matched to the producing firm's unit labor cost, we reject the hypothesis of a full and immediate pass-through of marginal cost. Since we focus on idiosyncratic variation, this does not fit the predictions of the Maćkowiak and Wiederholt (2009) version of the...

Starting from the assumption that firms are more likely to adjust their prices when doing so is more valuable, this paper analyzes monetary policy shocks in a DSGE model with firm-level heterogeneity. The model is calibrated to retail price microdata, and inflation responses are decomposed into...

We review the recent literature that studies new, detailed micro data on prices. We discuss implications of the new micro data for macro models. We argue that the new micro data are helpful for macro models, but not decisive. There is no simple mapping from the frequency of price changes in...

We study optimal pricing rules for a public large-value payment system (LVPS) that produces a public good (like prevention of systemic risk) but faces competition by a private LVPS for the private provision of large value payments. We show that the marginal cost of the public LVPS has to be...

We use microdata to estimate the strength of price selection - a key metric for the effect of monetary policy on the real economy. We propose a product-level proxy for mispricing and assess whether products with larger mispricing respond with a higher probability to identified monetary and...
