Ignorance enables individuals to act immorally. This is well known in policy circles, where there is keen interest in lowering moral ignorance. In this paper, we demonstrate the relevance of demand elasticity to ignorance by showing that small monetary incentives can significantly reduce...

In line with the empirical evidence, information averse investors observe the value of their portfolios infrequently; inattention is more...

We propose a new principle for measuring the cost of information structures in rational inattention problems, based on the cost of generating the information used to make a decision through a dynamic evidence accumulation process. We introduce a continuous-time model of sequential information...
