How does an industry characterized as differentiated serve as a barrier to entry? Besides explaining what the barrier means, explain how a potential new entrant specifically is going to be at a disadvantage. How do you identify/measure the advantage for incumbent firms - give me two viable measures/metrics that would identify/measure this advantage. For each metric explain why the metric is especially meaningful for illustrating your point and addressing the topic of differentiation in an industry serving as a barrier to entry. Additionally, what are the options for a potential entrant who faces this barriers, still wants to enter the industry, be competitive, and not accept below-normal performance (give me 1 viable option)? Please note: this question does not ask you about a firm effect. This question asks about an industry effect.
