JAMMING A RIVALS LEARNING

Can a firm (F) cause a rival (R) to learn less about R? Does F care? I explore F's ability and incentive to affect, or ''jam,'' R's private learning about R. The model developed does not have unobserved actions or ex ante asymmetric information which previous jamming models requi re. I find that F wants R not to learn and the more uncertain F believ es R is, the more F wants to jam R's learning. Entry deterrence increa ses with an entrant's uncertainty, causing R to want F to believe that R is more certain about R's beliefs than R really is. (C) 1995 Academ ic Press, Inc.
