Optimizing Information in the Herd: Guinea Pigs, Profits, and Welfare
AbstractHerding arises when an agent's private informationis swamped by public information in what Jackson and Kalai (1997) call a recurring game. The agent will fail to reveal his own information and will follow the actions of his predecessor and, as a result, useful information is lost, which might have highlighted a better choice for later decision-makers. This paper evaluates the strategy of forcing a sub-set of agents to make their decision early from the perspective of a social planner, and a firm with a valuable or valueless procuct. Promotional activity by firms can be explained as an attemps to overcome the herd externality and maximize sales.
