Treasure Hunt : Social Learning in the Field

Mobius, Markus - 2015

aggregation jointly shape social learning. Our environment features substantial social learning. We show that learning occurs via … transmitted noisily. We then compare two theories of information aggregation: a naive model in which people double-count signals … source of information. We show that to distinguish between these models of aggregation, it is critical to explicitly account …

Selecting Directors Using Machine Learning

Erel, Isil - 2018

Can algorithms assist firms in their decisions on nominating corporate directors? We construct algorithms to make out-of-sample predictions of director performance. Tests of the quality of these predictions show that directors predicted to do poorly indeed do poorly compared to a realistic pool...

Rational Inattention and Sequential Information Sampling

Hébert, Benjamin - 2017

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...
