Regulations usually apply to all members of an industry. Professors Ayres and Braithwaite propose that in some situations "partial industry" regulation is superior to all-or-nothing regulatory policies. Partial-industry regulation governs only a part of an industry, leaving other parts either unregulated or disparately regulated. Regulating only an individual firm (or subset of firms) can engender a system of checks and balances in which the regulated and unregulated portions of the market each curb the excesses of the alternative form of market governance. Partial-industry regulation can thus promote efficiency by restraining monopoly power without giving rise to the evils of either captured or benighted regulation. The author's theories of partial-industry intervention gain support from an analysis of monopsonist behavior.

Governments interested in promoting consumer welfare should often emulate what a monopsonist consumer would do. One way to reconceive of the regulator's decision whether to subsidize fringe competition is to ask if a hypothetical downstream monopsonist would subsidize upstream entry to "second-source" the product. A monopsony standard provides not only a powerful tool for analyzing how government might intervene to protect consumers, but also a limiting principle for analyzing when intervention is appropriate.

INTRODUCTION

Federal and state regulation of the United States economy often displays an all-or- nothing character: regulations govern either all members of an industry or none. A host of federal agencies pervasively regulate the conduct of entire industries. For example, the Securities and Exchange Commission regulates the securities industry, the Food and Drug Administration regulates the production of pharmaceuticals, and the Federal Reserve regulates the banking industry. In addition, many regulations promulgated under federal statutes, such as the Clean Air Act, mandate or prescribe certain dimensions of industry behavior. Even among industries that are not extensively regulated, those regulations that do exist tend to apply to all industry members or none.

Not surprisingly, the academic and political discussion of regulation mirrors this dichotomous reality. The deregulation debate often implicitly considers only two regulatory alternatives: government must either impose industry-wide regulations or allow unconstrained markets to determine the allocation of scarce resources. The regulatory literature has identified significant costs associated with each alternative. Laissez-faire policies that leave monopoly or oligopoly power unchecked in private hands might allow industry members to raise their prices above the competitive level. But industry-wide regulation might have the same effect: regulators can be "captured" by the very firms they attempt to regulate. Captured regulators can organize a cartel among producers in an industry and legally mandate that these firms sell at an inflated price. For those who fear these costs of capture, the only thing worse than letting market power coalesce in private hands is giving a corrupt Leviathan the power to define the parameters of market transactions.

Even uncaptured regulators face significant informational hurdles in promulgating efficient regulations. Regulatory agencies may have great difficulty ascertaining the proper "competitive" price because production costs are not observable. If the agency guesses too low, firms will not recoup their costs; if the agency guesses too high, consumers again will be forced to buy at cartel-like prices.

This Article explores a middle path between the Scylla of full industry regulation and the Charybdis of laissez-faire policies. We propose that in some situations "partial- industry" regulation may be superior to all-or-nothing regulatory policies. In its broadest sense a regime of partial-industry regulation would allow a government to regulate only part of an industry,leaving the rest unregulated. Under partial-industry regulatory schemes, government purposefully treats firms in an industry differently.

In some regulatory settings, regulating only an individual firm (or a subset of the firms) in an industry can promote efficiency by restraining monopoly power without giving rise to the evils of either captured or benighted regulation. Especially in a dynamic or evolutionary sense, partial-industry regulation might be more resilient to private and public abuses of market power. Our theory derives its strength from both camps of the regulation/deregulation debate. Like advocates of regulation, we accept that unregulated markets sometimes fail to produce competitive prices. But like advocates of deregulation, we also acknowledge that unregulated competitors have strong incentives to chisel away at cartel agreements and thereby destabilize collusion. Unlike full-industry regulation, which extinguishes many benefits of interfirm competition, partial-industry regulatory strategies try to harness and foster the welfare-enhancing effects of competition.

Partial-industry regulation begins with the premise that the existence of a single or a few competitive firms can dramatically affect the competitive conduct and performance of an entire industry. The central insight of partial-industry regulation is that government can accomplish many regulatory goals by maintaining the competitive performance of a subset of the firms in an industry. Far from denying the powerful effect of competition, partial-industry regulation uses the regulated firms to affect the behavior of other firms in the market. Unlike across-the-board industry regulation, however, mistaken or captured government decisions do not necessarily adversely affect the unregulated firms. Instead of completely displacing the market, partial- industry regulation maintains a structure of "checks and balances" between the two extremes of regulation.

Partial-industry regulation can be seen as a form of regulatory delegation. The regulated firms in the industry indirectly bear the burden of assuring that the unregulated firms comply. The compliance of unregulated firms is assured because competition forces them to match the offers of the regulated firm. Therefore, unlike other strategies of delegation, the regulated firms do not need to appreciate their disciplining function.

A major thesis of this Article is that government should adopt a "monopsony standard" for consumer protection interventions. Under this standard, government should only intervene on consumers' behalf to improve the workings of a market in situations where a monopsonist buyer would rationally intervene on its own behalf. The monopsony standard provides strong indications of when and how government should intervene. Monopsonists represent the quintessentially empowered consumer. By studying how these consumers with market power protect themselves, government can better target and tailor interventions on behalf of less powerful consumers. We argue that a monopsony standard provides particularly strong evidence supporting the use of partial-industry regulation because monopsonists often undertake their own private analogues to partial-industry interventions.

A monopsony standard for consumer protection is also attractive because it provides a limiting principle indicating when government should intervene. As discussed below, the private practice of second-sourcing-subsidizing second sources of supply-shows that treating sellers differently can indeed be rational in individual cases, and provides government with guidelines for distinguishing situations in which government-sanctioned disparate treatment is likely to be rational from situations in which it is not. The monopsony standard thus provides a powerful source of necessary (but not sufficient) conditions for intervention. Even when a monopsonist would intervene, the particular costs of government intervention might preclude the use of partial-industry regulation. Thus, the monopsony standard more concretely provides a limiting principle to government actions, suggesting that if a monopsonist would not intervene to change a market outcome, government should not either.

From the prevailing all-or-nothing regulatory mind-set, many forms of partial-industry regulation might seem radical. This Article provides a theoretical justification for further exploration of partial-industry regulation, bolstering its thesis with examples of successful private and public interventions that disparately regulate the sellers in particular markets. For the most part we argue for government regulatory attempts that promote competitive pricing in industries. But our larger argument is that partial-industry regulation can be a useful policy tool to correct other types of market failure as well. Government intervention directed at a subset of firms in an industry, for example, can spur the development of additional safety precautions, innovation, or information without completely forgoing the checks and balances of private competition.

Our argument is not that partial-industry regulation is costless or that it should be pursued on an economy-wide basis. For one thing, partial-industry regulation raises constitutional issues of equal protection that are analyzed below. Additionally, as we make clear, there are significant costs to partial-industry regulation that will clearly preclude its use in several regulatory contexts. But to be viable, partial-industry regulation must only succeed in doing better than the all-or- nothing alternatives. In some circumstances, we prefer the rifle to either the shotgun or no gun at all.

We begin by setting out both a theoretical and practical typology of partial-industry regulation. By analyzing both the costs and benefits of such intervention, we show that government could use a diverse range of possible partial-industry interventions to promote competition. We next discuss the monopsony standard as a guide for government intervention strategy. Potential equal protection problems resulting from disparate treatment of firms within the same industry are then analyzed. We end by discussing a series of applications- industry studies of oil, passenger airline service, news media, and long-distance telephone service-in which single-firm or partial-industry regulation is currently in place or might be justified.
