In the mid-twentieth century, antitrust jurisprudence in the United States was largely guided by the structure-conduct-performance (SCP) paradigm. This framework posited that market structure—specifically, the number and size of firms—directly dictated firm conduct, which in turn determined market performance. SCP adherents argued that high market concentration inherently facilitated collusion and erected insurmountable barriers to entry, thereby necessitating aggressive judicial intervention to deconcentrate industries. Consequently, courts during this era routinely struck down mergers that resulted in even modest increases in market share, operating under the assumption that such consolidation inevitably harmed consumer welfare by suppressing competition.
By the 1970s, however, a profound intellectual shift occurred with the ascendance of the Chicago School of antitrust analysis. Grounded in neoclassical price theory, Chicago School scholars fundamentally rejected the SCP’s structural determinism. Instead, they argued that market concentration was frequently the result of superior efficiency and economies of scale rather than anticompetitive intent. According to this view, true barriers to entry were exceedingly rare and generally limited to those created by government regulation. The Chicago School contended that practices previously condemned as anticompetitive under the SCP paradigm—such as predatory pricing—were largely irrational and self-defeating. They reasoned that a dominant firm attempting to drive out competitors by pricing below cost would incur massive losses, only to see new entrants flood the market the moment it attempted to raise prices to recoup those losses, assuming no government-enforced entry barriers existed. Thus, the Chicago School advocated for a jurisprudential standard focused exclusively on demonstrable harm to consumer welfare, typically measured by output restrictions or price increases, rather than mere market concentration.
The passage most strongly supports which of the following inferences regarding the Chicago School's conclusion that predatory pricing is "largely irrational and self-defeating"?
- It relies on the condition that the state has not instituted regulations that would preclude new firms from entering the market once the dominant firm attempts to recover its accumulated deficits.Answer
- BIt is based on the conviction that high market concentration intrinsically empowers dominant firms to erect insurmountable barriers against potential new entrants.
- CIt is predicated on the absolute certainty that any enterprise attempting to price below cost will immediately face total financial ruin.
- DIt assumes that new market entrants will consistently operate with superior efficiency and greater economies of scale than the dominant firm.
- EIt requires that courts routinely intervene to strike down pricing strategies that fail to demonstrably enhance consumer welfare.
