In the seminal rational inattention model of Matĕjka and McKay (2015), logit demand arises from the discrete choice of agents who are uncertain about choice payoffs and have access to a flexible, costly information acquisition technology (RI-logit). A notable limitation of this powerful...

We present a novel approach to finite Rational Inattention (RI) models based on the ignorance equivalent, a fictitious action with state-dependent payoffs that effectively summarizes the optimal learning and conditional choices. The ignorance equivalent allows us to recast the RI problem as a...

Economic theory reduces the concept of rationality to internal consistency. The practice of economics, however …, distinguishes between rational and irrational beliefs. There is therefore an interest in a theory of rational beliefs, and of the …

We study how effectively long-lived rational agents learn from repeatedly observing each others’ actions. We find that in the long run, information aggregation fails, and the fraction of private information transmitted goes to zero as the number of agents gets large. With Normal signals, in...
