Behavioral Equilibrium in Economies with Adverse Selection

Esponda, Ignacio·2008·American Economic Review

Abstract

I propose a new solution concept—behavioral equilibrium—to study environments with players who are naive, in the sense that they fail to account for the informational content of other players' actions. I apply the framework to certain adverse selection settings and show that, contrary to the existing literature, the adverse selection problem is exacerbated when naive players fail to account for selection. More generally, the main distinguishing feature of the framework is that, in equilibrium, beliefs about both fundamentals and strategies are jointly restricted. Consequently, whether a behavioral bias may arise or not is determined endogenously in equilibrium. (JEL C70, D82, D83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
