strategies that contribute to welfare enhancement of consumers from ones that reduce the welfare of consumers. That task is becoming more complex and difficult with the possible presence of predatory marketing strategy, i.e. supracompetitive pricing (Gundlach, 1995). Price predation represents only one possible strategy of companies that seek to strengthen their market position, but it is not necessarily the only marketing strategy the company applies in order to gain market power. The predatory strategy can be used in combination with other strategies such as non-predatory strategy that is focused on raising the costs of rivals’ products and services. References Phillip E.
