We propose a new approach to modeling the cost of information structures in rational inattention problems, the "neighborhood-based" cost functions. These cost functions have two properties that we view as desirable: they summarize the results of a sequential evidence accumulation problem, and...

Experimental demonstration of systematic errors and biases in human choice behavior might seem to undermine the conceptual basis of the individualistic approach to welfare analysis, in which people's interests are inferred from the choices that they are observed to make. This essay argues that...
