We study equilibrium determination in an environment where two kinds of agents have different information sets: The fully informed agents know the structure of the model and observe histories of all exogenous and endogenous variables. The less informed agents observe only a strict subset of the...

This paper presents a general framework for constructing and solving the multivariate static linear quadratic Gaussian (LQG) rational inattention tracking problem. We interpret the nature of the solution and the implied action of the agent, and we construct representations that formalize how the...

Macroeconomic models with microeconomic foundations face a difficult task: they must be consistent with facts both large and small. This paper proposes a model that combines two strands of the literature on stickiness in order to match both sets of facts. (1) Firms acquire information...

Rational inattention theory is economic theory that recognizes that people have finite information-processing capacity, in the sense of Shannon and engineering information theory. This approach is still in the early stages of development, but it promises to provide a unified explanation for some...

How does the sensitivity of prices to public information changes along a production chain? We examine this question in a setting where prices in a stage affect the cost of next stage firms and also contain information about the unobserved state of the economy. Our results depend on the...

The aim of this study is to assess the extent to which the degree of heterogeneity of inflation expectations is driven by the flow of information related to current and future price developments. To that end, we follow three routes: i) We propose different measures of information flow that have...

Despite large deregulation efforts, informal economic activity still represents a large share of GDP in many developing countries. In this paper we look at incentives to reduce informal activity when capitalists in the formal sector regulate entry. We consider a dual economy with a formal sector...
