While vintage differentiation is a highly prominent feature of various regulations, it can induce significant biases. We study these biases in the context of New Source Review—a program within the US Clean Air Act imposing costly sulfur dioxide (SO2) abatement requirements on new boilers but not existing ones. In particular, we empirically investigate how the differential treatment of coal boilers shaped the generation landscape by affecting unit utilization, retirement, and emissions. Focusing solely on the additional SO2 emissions, we estimate annual costs of up to $65 billion associated with the vintage differentiation in New Source Review.

In West Virginia v. EPA, the Supreme Court expressly relied on the “major questions doctrine” for the first time in a majority opinion to hold that a federal agency lacked authority to issue a regulation. Published in the William and Mary Environmental Law and Policy Review, this paper explores whether West Virginia provides such a framework and concludes that it does. A close look at West Virginia and the alternative frameworks that parties and others urged on the Court in the West Virginia litigation also reveals a great deal about what the major questions doctrine is not.

In recent years, federal courts have increasingly assessed the legality of regulatory action by considering its antecedents, or lack thereof, in prior agency actions. Yet as this article explains, federal agencies have insufficiently adapted to this increased judicial focus on regulatory antecedents. While significant agency rulemakings typically include extensive dockets with many different types of analysis, they have generally provided limited analysis of regulatory antecedents. This article suggests that agencies more extensively catalog regulatory antecedents at all stages of the rulemaking process, from drafting to promulgation.

This study examines how banks respond to earthquakes that convey seismic risk salience but do not cause damage, i.e., noticeable non-damaging earthquakes (NNDEs). Using evidence from California, we find loans more likely to be denied or sold after increased NNDEs. Banks with fewer assets, more diversified branching markets, or stronger sales capability relied more on securitization to transfer the perceived seismic risk. We show evidence that banks likely learned about the NNDEs through personal experience and local news. The effects of NNDEs persisted up to three years. Meanwhile, the NNDEs only caused moderate and temporary collateral devaluation but did not increase the observable default risk. Thus, banks' responses most likely resulted from the increased risk salience of future damaging earthquakes during the mortgage term. Our findings call for reevaluations of the heuristics in banks' risk-perception updating and have implications for designing more efficient disaster risk-sharing mechanisms in the financial market.

While academic research on Distributed Energy Resources (DERs) has been mostly focused on first-best systems, we hypothesize that in reality multiple information barriers to efficient DER roll-out exist. We thus study the prevalence and importance of information issues arising in the context of deployment of DERs by reviewing the existing engineering and economic literature on distributed resources, analyzing DER-related regulatory proceedings, and surveying the relevant electricity sector stakeholders for their perception of information relevance and accessibility.
