“…This can be the case when the short-term profit-reducing action is part of a tit-for-tat strategy that allows players to sustain a cooperative outcome in a dynamic game (Kreps et al 1982). Alternatively, inflicting harm on the competitor may maximize profit in the long run if the competitor is ultimately eliminated (Parks, Pharr, and Lokeman 1994). Nevertheless, it seems reasonable to argue that most market situations are not really zero-sum games; in general, increased competition results in lower profits for firms and more benefits for customers (Boynton, Blake, and Uhl 1983; Brodie, Bonfrer, and Cutler 1996; Leeflang and Wittink 1996).…”
