In order for capital markets to function well, investors need accurate information about securities. If investors do not trust firms’ disclosures, they will discount what they are willing to pay for securities, increasing the cost of capital and thereby making it more difficult, even for honest firms, to fund productive endeavors. Moreover, investment decisions based on inaccurate information distort the efficient allocation of resources in an economy. As it has artfully been put, “A world with fraud…is a world with too little investment, and in the wrong things to boot.”1 Deterring fraud in the capital markets should therefore be a government priority.2

But the devil, as is so often the case, is in the details. If poorly constructed, a deterrence regime can produce the very harms it is meant to prevent: Just as securities fraud increases the cost of capital and reduces allocative efficiency, so, too, can misguided enforcement. This happens when firms, fearing erroneous prosecution and legal error, choose not to disclose information that may be helpful to investors, out of fear it will be deemed misleading, or, conversely, bury investors in an avalanche of trivial information, out of fear that its omission will give rise to liability. With less useful information to guide their decisions, investors will again discount what they pay for securities and may end up investing in the wrong things. Misguided enforcement also imposes a variety of other deadweight costs on firms and, ultimately, their shareholders, operating as a drag on economic growth.3

The goal of a securities-fraud deterrence regime should be to minimize the sum of the costs that securities fraud produces and the costs that the deterrence regime itself produces—both direct enforcement costs and the over-deterrence costs that result when companies fear inaccurate prosecution and legal error. It is, of course, difficult to observe and measure these costs, and thus to empirically prove that a regime has achieved or failed to achieve this goal. But where empirics fail theory can still offer guidance. This chapter discusses the fundamental design choices that policymakers must confront when attempting to construct an optimal securities-fraud deterrence regime, and offers what theory suggests is the best approach to each. The analysis reveals that the United States’s current approach to securities-fraud deterrence falls far short of the ideal.

The Building Blocks

If policymakers were designing a securities-fraud deterrence regime from scratch, they would necessarily confront several basic questions. These include: Should civil or criminal penalties be imposed? On whom? By whom? This part briefly discusses these choices and the impact they can have on the ultimate efficiency of a deterrence regime.

Should Securities Fraud Carry Criminal or Civil Penalties? A threshold question that must be addressed in designing any deterrence regime is whether to impose criminal or civil penalties on offenders. In modern practice, the civil–criminal divide has become increasingly blurred—civil enforcement agencies often pursue remedies that appear designed to punish, while criminal enforcement agencies often impose fines for regulatory offenses that lack a mens rea requirement.4 But at a theoretical level, a clear distinction can be drawn: Regardless of how they are labeled or who enforces them, civil penalties can be thought of as those meant to “price” behavior, whereas criminal penalties can be thought of as those meant to “sanction” behavior.5 Under this conception, civil penalties should be set at a level designed to force potential defendants to internalize the costs their activities impose on society, much like a Pigouvian tax;6 criminal penalties, by contrast, should be set high enough to deter the behavior unconditionally.7

It follows that criminal penalties should be reserved for conduct that has no redeeming social value—a category that securities fraud surely falls within. Criminal sanctions would not be appropriate, however, if the conduct sought to be regulated is not securities fraud itself, but company-level efforts to prevent fraud within the organization. Clearly, companies should not spend unlimited amounts on such efforts; rather, they should invest in them only so long as the social benefits produced exceed the marginal cost—something that civil (but not criminal) penalties encourage of companies.

Even when limited to the direct perpetrators of fraud, criminal penalties must be deployed with caution. Because they are by design severe, criminal penalties raise serious over-deterrence concerns to the extent that inaccurate prosecution and legal error are risks. How severe of a problem this proves to be will depend on other features of the liability regime. For example, the scope of the substantive fraud prohibition will make a difference, as will procedural issues, such as the burden of proof—the vaguer the boundaries of the law, and the easier it is to establish culpability, the more likely that honest individuals will distort their disclosure choices to avoid mistakenly getting caught in the law’s web.8 Perhaps the most important factor that will influence the level of over-deterrence, however, is the identity of the enforcer, a topic discussed more fully below.

To Whom Should Liability Attach? The best way to deter a scienter-based offense like securities fraud is to credibly threaten the individuals who would commit it with criminal penalties.9 The criminal penalties threatened should include imprisonment, but need not be so limited. As explained above, what makes a penalty “criminal” is that it is severe enough to discourage the activity unconditionally. Monetary fines and orders barring defendants from working for public companies or in the securities industry can fit this definition, as well, if they impose expected costs on individuals that exceed any possible expected benefits from committing fraud.

When the individuals who would commit fraud are acting as corporate agents, a case can sometimes be made for also threatening the corporation with civil (but not criminal) penalties:10 Forcing corporations to internalize the costs imposed on society by the frauds committed by their agents, the argument goes, creates incentives for corporations to invest efficiently in internal controls to deter it.11 Of course, a corporation is a legal fiction, one characterized by a separation of ownership from control. As its residual claimants, it is ultimately the shareholders of the corporation who bear the cost of corporate-level liability. A more precise statement of what corporate-level liability is meant to do, then, is to incentivize shareholders to use the tools available to them to push corporate managers to take efficient steps to deter fraud within the organization. It thus assumes that shareholders do not already have natural incentives to do so.

This assumption is probably not true of the institutions who own the majority of U.S. public company stock.12 Institutional investors like mutual funds and pension funds are among the primary victims of securities fraud, so they have natural incentives to prevent it.13 Indeed, most scholars today view securities fraud by public companies as primarily a species of agency cost—corporate managers commit fraud in order to hide their poor performance, thus allowing them to game incentive compensation programs and avoid other forms of shareholder discipline.14 Imposing liability on public companies when managers commit fraud is thus akin, as one commentator has observed, “to punishing the victims of burglary for their failure to take greater precautions.”15

Who Should Enforce the Prohibition? Another important decision that policymakers must make when designing a deterrence regime is to whom to assign enforcement authority. As a general matter, public enforcement is to be preferred over profit-driven private enforcement. This is especially so with respect to criminal penalties. Even a small risk of inaccurate prosecution and legal error can produce significant over-deterrence costs when criminal penalties are threatened, and this risk is likely to be higher under a regime of private enforcement than public enforcement. Profit-driven private enforcers are likely to bring all cases that have a positive net present value to them, even if of borderline merit, and to ignore those that do not. A public enforcer, by contrast, is more likely to consider the broader social impact of its enforcement choices—including both the fraud its choices might deter and the costs they might produce. To be sure, public enforcement agencies are far from perfect, and may sometimes base enforcement decisions on undesirable criteria. Nevertheless, it is usually easier to monitor, control, and discipline public servants than it is to force the alignment of private incentives with the social goal of optimal fraud deterrence. It is not surprising, then, that throughout the developed world the enforcement of criminal law is entrusted to public authorities.16

Private enforcement of civil penalties can be problematic, as well. Although less severe than criminal penalties, civil penalties can likewise produce over-deterrence costs to the extent that individuals fear inaccurate prosecution and legal error—something that, again, is more likely under a regime of private enforcement. In addition, it can be difficult to craft accurate and stable civil penalties under a regime of private enforcement, given that penalty levels can be expected to drive the amount of private enforcement activity.17

This is not to say that private parties should be denied traditional compensatory remedies if they find themselves the victim of securities fraud. To the contrary, the prospect of being able to recover one’s losses in the event of fraud encourages participation in the capital markets, and discourages inefficient investments in precautions.18 Meanwhile, the traditional common-law restrictions on private fraud claims—such as the need to prove actual reliance and damages—serve to limit the over-deterrence risk these types of lawsuits present.19

With respect to the allocation of enforcement authority as between the federal government and state governments, the federal government should have the leading role in policing fraud in the national capital markets, whereas state enforcers should focus on intra-state frauds. No individual state would fully capture the benefits of deterring fraud in the national capital markets, as those benefits would spill over to the national economy; thus, states might predictably underinvest in the effort. Conversely, states “might use their authority aggressively to impose monetary sanctions on offenders to generate revenue for their state, without fully internalizing the potential over-deterrence costs of their actions.”20

How the Current System Measures Up

The straightforward tenets outlined above counsel in favor of a securities-fraud deterrence regime that bears little resemblance to the one that exists in the United States today. To recap: Theory suggests that the individuals who would commit securities fraud should be threatened with criminal penalties, enforceable by a federal public enforcer when the conduct implicates the national capital markets. Corporate-level liability for securities fraud may also make sense with respect to firms that are closely held, but is difficult to justify with respect to public companies. And when corporate-level liability is warranted, the penalties threatened should be civil—never criminal. Finally, private enforcement is best limited to traditional common-law compensatory remedies or close analogues.21

 Now compare the U.S. system. Public companies routinely face corporate-level liability for securities fraud committed by their agents, while the responsible agents often escape punishment entirely. This is almost always true in private securities fraud litigation.22 The Securities and Exchange Commission (SEC) and Department of Justice impose penalties on individual defendants with greater frequency, but have also been criticized for favoring headline-grabbing high-dollar settlements with public companies, to the ultimate detriment of innocent shareholders, over pursuit of actual individual wrongdoers.23

Moreover, public companies face not just civil penalties for securities fraud but criminal penalties, as well. This is true both in the formal sense that they may be pursued by the criminal division of the Justice Department, and in the functional sense that the penalties with which they are threatened (by both the Justice Department and the SEC) often seem calibrated to “sanction” rather than to “price.”24 Worse yet, public companies also face criminal penalties (in the functional sense) at the hands of profit-driven private enforcers. Fraud-on-the-market class actions brought under SEC Rule 10b-5 retain the out-of-pocket measure of damages associated with a common-law fraud action, but they are not subject to other traditional limitations on common-law fraud suits, such as the need to prove actual reliance.25 As a result, all investors who purchased stock in a public company on the secondary market at a price affected by an alleged misstatement or omission are included in the plaintiff class, and stand to recover the full amount of their losses with no offset for the gains to the counterparties to their trades. Fraud-on-the-market class actions therefore threaten public companies with truly enormous damage awards—awards that likely far exceed what might be necessary to force them to internalize the social costs of their agents’ frauds.26

Finally, while, as a general matter, the federal government focuses on fraud in the national capital markets and state governments focus on intrastate frauds, states are free to pursue national frauds without any need to notify or coordinate with the federal government.27  This has occasionally led to duplicative, follow-on state enforcement actions against public companies that have already reached a settlement with federal authorities.28 Such actions generate revenue for the enforcing state but fail to produce meaningful deterrence benefits.


The securities-fraud deterrence regime that exists in the United States today deviates in significant ways from what theory suggests is optimal. If writing on a clean slate, policymakers would be well-advised to design a system that: (1) places more emphasis on individual liability; (2) eschews corporate criminal penalties entirely; (3) focuses the imposition of corporate civil penalties on companies whose shareholders would otherwise have poor incentives to adopt internal control systems to deter fraud; (4) limits private enforcement to traditional common law remedies or other compensatory remedies possessing similar safeguards against over-deterrence; and (5) better delineates and coordinates the authority of federal and state securities fraud enforcers.

If this fear extends to the third parties who assist corporations in the disclosure process, such as auditors and investment banks, they will charge more for their services. Fear of erroneous fraud liability might also distort companies’ financing choices.

For example, if a manufacturer pollutes, and the pollution causes a harm of $100 per unit of pollution to people who live in the area, then the firm should pay a tax of $100 per unit of pollution. This ensures that the manufacturer pollutes only if the value of the pollution-generating activities exceeds the harm, such that the social value of those activities is positive.” Jonathan S. Masur and Eric A. Posner, “Toward a Pigouvian State,” University of Pennsylvania Law Review, Vol. 164 (2015), pp. 94–95. Because the likelihood of imposition is less than 100 percent, civil penalties should be set higher than the net social costs of the conduct to reflect the probability of non-detection.
