In the United States, the primary tool to value greenhouse gas emissions reductions in cost-benefit analysis is the social cost of carbon (SCC), which is a metric that estimates, in monetary terms, the damages associated with climate change. Recently, some prominent public policy experts and scholars have proposed that a “marginal abatement cost” (MAC) could […]

Discount rates reflect the commonly held belief that a dollar today is worth more than a dollar tomorrow. Therefore, consistent with observed human behavior, governments use discount rates to weigh and compare present versus future costs and benefits in their decisions. The choice of discount rates greatly impacts which government regulations are cost-benefit justified, particularly […]

As the Biden administration attempts to make climate change the focus of many aspects of its domestic and international agenda, an independent federal regulatory agency—the Federal Energy Regulatory Commission (FERC)—finds itself at the center of debates over the nation’s energy policies and greenhouse gas (GHG) emissions. Under Sections 4 and 5 of the Natural Gas […]

The Trump administration wreaked havoc on U.S. climate policy by withdrawing from the Paris Agreement, undoing climate regulations, and undermining the foundation of future regulatory efforts. The Biden administration has begun to reverse the Trump administration’s climate rollbacks, but Democrats have struggled to enact legislation that would directly limit carbon emissions. Because federal climate policy […]

In the wake of the Reagan deregulation, America experienced twenty-eight years of regulatory progression, with precious little retrogression. That trend came to a crashing halt during the four years of Donald Trump’s presidency. As a candidate, Trump campaigned on a series of pledges to reverse and undo as much of the work done by Barack […]

The science is clear: the United States and the world must take dramatic action to address climate change or face irreversible, catastrophic planetary harm. Within the U.S.—the world’s largest historic emitter of greenhouse gas emissions—this will require passing new legislation or turning to existing statutes and authorities to address the climate crisis. Doing so implicates […]

In 2016, we co-authored a symposium article, The Grass is Not Always Greener: Congressional Dysfunction, Executive Action, and Climate Change in Comparative Perspective, 91 Chi.-Kent L. Rev. 139 (2016), that compared the impact of polarization on the process of creating climate change law and policy in the United States and Australia. We found that while […]

The social cost of greenhouse gases provides the best available method to quantify and monetize the climate damages attributable to the emission of an incremental unit of heat-trapping pollution. Accordingly, the metric can be highly useful for crafting policies that will reduce the nation’s greenhouse gas footprint, with potential usages including weighing the impacts of […]

As the Biden Administration works on updating the social cost of carbon (SCC), some economists are urging a different approach, known as the “Marginal Abatement Cost” (MAC) method or the “target-consistent” approach. Rather than attempting to calculate all the damage caused worldwide by each ton of carbon dioxide released into the atmosphere, the MAC approach […]

The Supreme Court’s ongoing efforts to narrow the contours of administrative agencies’ policymaking discretion comes at a particularly inopportune time. The nation faces a set of increasingly complex and pressing national problems, including climate change, that require the simultaneous application of careful deliberation and expertise, something Congress is ill-suited to do in the best of […]

Do foreign lives matter? When? How much? If one nation damages another, what are its obligations, as a matter of law and policy? These questions can be approached and understood in diverse ways, but they are concretized in debates over the “social cost of carbon,” which is sometimes described as the linchpin of national climate […]

Climate change poses an enormous risk to plant and animal species across the planet. Mean global temperatures have already increased by approximately 1ºC, causing environmental changes that affect species abundance, distribution, behavior, physiology, genetics, and survival prospects. These changes, combined with other human stressors, have already resulted in the extinction of some species and imperiled […]

The lenders that fund Chapter 11 reorganizations exert significant influence over the bankruptcy process through the contract associated with the debtor-in-possession (DIP) loan. In this Article, we study a large sample of DIP loan contracts and document a trend: over the past three decades, DIP lenders have steadily increased their contractual control of Chapter 11. […]

Public enforcement actions frequently result in the distribution of money to people affected by violations of market protection laws. This “public compensation” returns billions of dollars to consumers, investors, and others each year. The law of public compensation appears confusing at first impression because of inconsistent use of nomenclature and conceptual confusion. However, courts have […]

This Article addresses an important question in modern antitrust: when large investment funds have holdings across an industry, is competition depressed? The question of the impact of common ownership on competition has gained much attention as the role of institutional shareholding has grown, with the funds of the three largest management companies holding in aggregate […]
