Optimal actions of an agent facing a Shannon capacity constraint on the translation of an uncertain signal into an action can easily turn out to be discretely distributed, even when the objective function and the initial distribution of uncertainty contain no discrete elements. We show this...

Often, individuals must choose among discrete alternatives with imperfect information about their values, such as selecting a job candidate, a vehicle or a university. Before choosing, they may have an opportunity to study the options, but doing so is costly. This costly information acquisition...

Evidence shows that individuals do not always take tax attributes into account when making their choices. We focus on tax relief for charitable contributions. Although rational donors should view a match and a rebate of the same value as being equivalent, survey evidence shows that nominal...

This paper derives stylised facts on sectoral inflation dynamics and confronts these facts with two popular theoretical models of price setting. Based on sectoral price responses to macroeconomic shocks estimated from an approximate factor model, we find that the frequency of price changes...

We study forecasts of real GDP growth using a large panel of individual forecasts from 36 advanced and emerging economies over the period 1989–2010. We show that the degree of information rigidity in average forecasts is substantially higher than that in individual forecasts. Individual-level...

Beliefs have as pervasive a role as utility functions in economic models of choice, and are no more visible to the naked eye. This suggests the value of a data-theoretic approach to imperfect information along the lines of Samuelson's “revealed preference” approach to utility maximization. I...

We study the link between business failures, markups and business cycle asymmetry in the U.S. economy with a model of optimal firm exit under rational inattention. We show that the model's predictions of lagged, counter-cyclical and positively skewed markups together with counter-cyclical exit...

This paper derives the general equilibrium effects of rational inattention (or RI; Sims 2003,2010) in a model of incomplete income insurance (Huggett 1993, Wang 2003). We show that,under the assumption of CARA utility with Gaussian shocks, the permanent income hypothesis (PIH) arises in steady...

We study forecasts for real GDP growth using a large panel of individual forecasts from 36 advanced and emerging economies during 1989–2010. We show that the degree of information rigidity in average forecasts is substantially higher than that in individual forecasts. Individual level...
