Asymmetric Attention
Abstract
We document simultaneous over- and under-responses to new information by households,firms, and professional forecasters in survey data. Such behavior is inconsistent
with existing theories based on either behavioral bias or rational inattention. We
develop a structural model of information choice in which people base expectations
on observables that can reconcile the seemingly contradictory facts. We show that
optimally-chosen, asymmetric attention to different observables can explain the coexistence of over- and under-responses. We then embed our model of information
choice into a micro-founded macroeconomic model, which generates expectations consistent
with the survey data. We demonstrate that our model creates over-optimistic
consumption beliefs in booms and predictability in consumption changes.
