This paper develops a decision-theoretic framework to study rational inattention (Sims [1998, 2003]). We provide an axiomatic characterization that relates rationally inattentive behavior to attitudes towards flexibility (Kreps [1979]) and temporal resolution of uncertainty (Kreps and Porteus...

This paper conducts a systematic comparison of behavioral economics’s challenges to the standard accounts of economic behaviors within three dimensions: under risk, over time and regarding other people. A new perspective on two underlying methodological issues, i.e., interdisciplinarity and...

Expected utility theory (EUT) is currently the standard framework which formally defines rational decision-making under risky conditions. EUT uses a theoretical device called von Neumann-Morgenstern utility function, where concepts of function and random variable are employed in their...

We study belief updating about relative performance in an ego-relevant task. Manipulating the perceived ego-relevance of the task, we show that subjects update their beliefs optimistically because they derive direct utility flows from holding positive beliefs. This finding provides a behavioral...

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...

Attention scarcity is a limitation on the ability to incorporate information into actions with state-contingent consequences. In a menu choice setting, we study an axiomatic model of decision making with scarce attention. A decision maker satisfying our axioms acts as if she chooses a joint...
