The flexibility to renegotiate can facilitate long-term contracting and thereby beneficial reliance investments and risk allocation. The prospect of modification can induce contracting parties who expect their bargaining power to improve to enter into contracts earlier and realize the advantages of longer-term relationships. Otherwise, those parties might decline to contract or delay until those opportunities realize, thereby foregoing the benefits of long-term risk allocation or reliance investments. The parties decide not only whether, but also when, to make legally binding commitments to each other. Courts should be more lenient in enforcing contract modifications that, prompted by a shift in bargaining power, may have only a redistributive effect. Parties can design under-compensatory damages that would provide a credible threat of breach ex post to facilitate ex post modification. Requiring good faith in modification (along with damages) can constrain possible holdup and protect reliance investments and risk allocation.

The central concern of structural constitutional law is the organization of governmental power, but power comes in many forms. This Article develops an original account of data’s structural law—the processes, institutional arrangements, transparency rules, and control mechanisms that, we argue, create distinctive structural dynamics for data’s acquisition and appropriation to public projects. Doing so requires us to reconsider how law treats the category of power to which data belongs. Data is an instrument of power. The Constitution facilitates popular control over material forms of power through distinctive strategies, ranging from defaults to accounting mechanisms. Assessing data’s structural ecosystem against that backdrop allows us to both map the structural law of data and provide an initial diagnosis of its deficits. Drawing on our respective fields—law and computer science—we conclude by suggesting legal and technical pathways to asserting greater procedural, institutional, and popular control over the government’s data.

Eviction cases make up over a quarter of all cases filed in the federal and state civil courts and have enormous consequences for tenants, who are nearly always unrepresented by counsel. These cases overwhelmingly settle, yet settlement scholars have entirely overlooked eviction both empirically and theoretically. The Article presents results from the first empirical study of eviction settlement negotiations. The study involved rigorous analysis of an original dataset of over one thousand hand-coded settlements, observations of settlement negotiations in the hallways of housing court, and dozens of interviews. The findings demonstrate that unrepresented tenants—who make up the vast majority of tenants in the eviction system—have no meaningful influence over settlement terms. Rather, the terms are set by landlords and their attorneys. Drawing on the empirical findings and scholarship about contracts of adhesion, the Article develops the theoretical concept of “settlements of adhesion.”

The negative moral emotions of guilt and shame impose real social costs but also create opportunities for policymakers to engender compliance with legal rules in a cost-effective manner. This Essay presents a unified model of guilt and shame that demonstrates how legal policymakers can harness negative moral emotions to increase social welfare. The prospect of guilt and shame can deter individuals from violating moral norms and legal rules, thereby substituting for the expense of state enforcement. But when legal rules and law enforcement fail to induce total compliance, guilt and shame experienced by noncompliers can increase the law’s social costs. The Essay identifies specific circumstances in which rescinding a legal rule will improve social welfare because eliminating the rule reduces the moral costs of noncompliance with the law’s command. It also identifies other instances in which moral costs strengthen the case for enacting legal rules and investing additional resources in enforcement because deterrence reduces the negative emotions experienced by noncompliers.
