We develop a fast, tractable, and robust method for solving the transition path of dynamic rational inattention problems in linear-quadratic-Gaussian settings. As an application of our general framework, we develop an attention-driven theory of dynamic pricing in which the Phillips curve slope...

We develop a tractable and portable method for characterizing the solution to dynamic multivariate rational inattention models in linear quadratic Gaussian settings. We apply our framework to propose an attention driven theory of the Phillips curve, the slope of which is endogenous to how...

How does competition affect information acquisition of firms and thus the response of inflation and output to monetary policy shocks? This paper addresses these questions in a new dynamic general equilibrium model with both dynamic rational inattention and oligopolistic competition. In the...

The cyclicality of markups is crucial to understanding the propagation of shocks and the size of multipliers. I show that the degree of inertia in the response of output to shocks can reverse the cyclicality of markups within implicit collusion and customer-base models. In both classes of...

We investigate biases in expectations across different settings through a large-scale randomized experiment where participants forecast stable stochastic processes. The experiment allows us to control forecasters’ information sets as well as the data generating process, so we can cleanly...

How are a firm’s size and market power related to one another? Combining micro-data about producers and consumers, we document that while firms mainly grow by selling to more customers, their markups are only associated with their average sales per customer. To study the macroeconomic...

This paper explores how different margins of market share are related to markups. Usingmerged microdata on producers and consumers, we document that a firm’s market share ismainly related to its number of customers, while its price-cost markup is associated only withits average sales per...
