On balance one would argue that our society is mixed on the question of allowing firms to operate with market power; we certainly don't permit unregulated monopolies from operating but we do have a lot of industries where firms are permitted to operate with substantial market power and/or large market shares. There are arguments for this and arguments against this. The arguments against this allowable concentration focus on the idea that firms with market power withhold output and force higher prices (than would be seen in competition). The arguments supporting higher concentrations focus on technical efficiency and meeting consumer needs. Provide an example of a firm with market power that operates with or without regulation and argue that certain benefits accrue to consumers and society because of this firm being permitted to operate. In a sense I am asking you to find good things about monopoly power
