Many Keynesian macroeconomic models are based on the assumption that firms change prices at different times. This paper presents an explanation for this "staggered" price setting. We develop a model in which firms have imperfect knowledge of the current state of the economy and gain information...

Real rigidities that limit the responsiveness of real marginal cost to output are a key ingredient of sticky price models necessary to account for the dynamics of output and inflation. We argue here, in the spirit of Bils and Kahn (2000), that the behavior of marginal cost over the cycle is...

Firms employ a rich variety of pricing strategies whose implications for aggregate price dynamics often diverge. This situation poses a challenge for macroeconomists interested in bridging micro and macro price stickiness. In responding to this challenge, we note that differences in macro price...

This paper presents evidence on the amount of price rigidity that exists in individual transaction prices. Using the Stigler-Kindahi data, I examine the behavior of individual buyers' prices for certain products used in manufacturing. My most important findings are: 1.The degree of price...

Under conditions of natural monopoly, private contracts or government regulation may attempt to avoid inefficiency by setting up a pricing formula. Once the capital stock is chosen,the right price to charge the buyer is marginal cost. But the point of this paper is that marginal-cost pricing...

The basic assumption of this paper is an attempt to be specific about price formation while retaining a fixed-price, quantity-constrained equilibration in the short-run. The second theme of this paper is the role of inventories in macrodynamics a topic of long-recognized importance, but one...

How does market concentration affect the potency of monetary policy? The ubiquitous monopolistic-competition framework is silent on this issue. To tackle this question we build a model with heterogeneous oligopolistic sectors. In each sector, a finite number of firms play a Bertrand dynamic game...
