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...

Bad News Travels Slowly : Size, Analyst Coverage and the Profitability of Momentum Strategies

Hong, Harrison G. - 2008

A number of theories have been proposed to explain the medium-term momentum in stock returns identified by Jegadeesh and Titman (1993). We test one such theory--based on the gradual-information-diffusion model of Hong and Stein (1997)--and establish three key results. First, once one moves past...
