Consistent with suppliers possessing private information, we find that the amount of trade credit that a supplier offers to a buyer and the ability of the buyer to pay the trade credit on time are both associated with future buyer abnormal stock returns.

with David Hirshleifer, Yaron Levi, Siew Hong Teoh: w24293
Psychological evidence indicates that decision quality declines after an extensive session of decision-making, a phenomenon known as decision fatigue. We study whether decision fatigue affects analysts’ judgments. Analysts cover multiple firms and often issue several forecasts in a single day. We find that forecast accuracy declines over the course of a day as the number of forecasts the analyst has already issued increases. Also consistent with decision fatigue, we find that the more forecasts an analyst issues, the higher the likelihood the analyst resorts to more heuristic decisions by herding more closely with the consensus forecast, by self-herding (i.e., reissuing their own previous outstanding forecasts), and by issuing a rounded forecast. Finally, we find that the stock market und...
