For over 50 years, economists have developed and refined methods to value environmental and other nonmarket goods to provide benefit estimates that are commensurate with goods that are exchanged in markets. Without these estimates, benefit cost analysis of environmental regulations risk erroneous conclusions regarding the net benefits of a regulation. The methods can be broadly categorized into revealed preference (that infer values from behavioral clues) and stated preference (which directly elicit values through surveys). Despite their longer history and the many documented shortcomings, revealed preference methods have not been subject to the intense validity and reliability challenges as their stated preference counterparts. And, unlike stated preference methods (see Johnston et al.2017), there has not previously been an effort for scholars of the approaches to develop a set of “best practice” guidelines for the implementation and reporting of these analyses.

Since electronic cigarettes were introduced, in 2007, they have presented controversial public health tradeoffs. E-cigarettes provide users with the addictive chemical nicotine but without exposing them to the harmful combustion-generated toxicants in cigarette smoke. On the one hand, because smoking combustible cigarettes is estimated to lead to almost 500,000 deaths each year, e-cigarettes have great potential as a harm reduction strategy. In particular, evidence from randomized clinical trials shows that vaping e-cigarettes helps adult smokers quit. On the other hand, the growing popularity of vaping among teens raises concerns about nicotine addiction, the possibility that vaping is a gateway to smoking, and unknown future health consequences. More teens now vape e-cigarettes than smoke cigarettes. In the National Youth Tobacco Survey, the fraction of high school students reporting vaping within the past 30 days increased from 11.7 percent in 2017 to 27.5 percent in 2019, before dropping to 19.6 percent in 2020.  Some public policies – increasing the legal purchase to 21 and banning e-cigarette flavors popular with teens – try to target teen vaping. Other policies, most notably e-cigarette excise taxes, discourage both adult and teen vaping.

Novel threats call us to action. Witness the response to the 9/11 attack and more recently to the coronavirus. Such risks may be particularly compelling if citizens do not understand how to deal with the harm or because of ambiguity around the probability that the threat will be realized.

Benefit-cost analysts essentially ask for a lot of trust. They look to inform policy decision-making by using a tool that boils very complex choices down to a seemingly simple comparison of the relative values of benefits and costs. If an analyst’s work is to be taken seriously, the decision makers must have confidence that the analyst is objective and competent, that the results being provided accurately capture what is known about any choice’s implications. The decision makers may have their own biases and interests and many choices will require decisions from a wide array of people with varying perspectives. But through the whole policy-making process, decision makers do not want to have to worry about hidden agendas, skewed data, or sloppy analysis in the information intended to inform their decisions.

AS A YOUNG CLINICIAN, I was interested in making a difference; it did not matter how much of a difference, as long as I could claim some patient benefit. And I really didn’t care what benefit: better survival, less local recurrence, shorter hospital stays, fewer narcotics—the specifics did not matter. With retrospective observational studies, it was easy to claim a benefit when I was demonstrating a potential or probable association. I intervened, and the patient improved! If I could prove that claim and make it look scientific with a randomized controlled trial, was I then done?

What a year it has been. Between the unfolding of a global pandemic and nationwide protests around the topic of police brutality, 2020 has already been a jam-packed year for public policy, and we haven’t even made it into election season.

Reducing COVID-19 risks requires making extraordinarily difficult decisions that trade-off saving lives and economic damages. Benefit-cost analysis is well-suited for investigating these trade-offs and informing these decisions. However, interpreting and using the results requires understanding the framework and addressing its limitations, including the uncertainties in the value of mortality risk reductions and the distribution of impacts across those who are advantaged and disadvantaged.

Benefit-cost analysis (BCA) is loosely interpreted as a method for determining whether a policy is ‘in the public interest’. More formally, BCA measures the effect of a policy change on each individual’s wellbeing as a monetary value and sums these values over the population. If the sum is positive, the policy change is declared a potential Pareto improvement, meaning the change plus some set of cost-free money transfers would be Pareto superior to the status quo (or other comparator).

More than 450,000 Americans died of an opioid overdose between 1999 and 2018. There were fifteen fatal opioid overdoses for every 100,000 individuals in 2018, a ratio five times greater than in 1999. While public health researchers and policymakers have rightly turned their attention toward remedying the global coronavirus pandemic, the U.S. opioid epidemic continues to take lives. In my dissertation, An Empirical Analysis of Policy Responses to the Opioid Epidemic, I analyzed the effect of various state and federal interventions to reduce opioid abuse and overdoses. This analysis can contribute to the benefit-cost analysis of policies that aim to decrease opioid consumption and overdose deaths.

Economic management in Australia has effectively been outsourced to health experts. Political and business leaders are deferring exclusively to public health advice about how to contain the COVID-19 virus with no serious public discussion of the economic costs.

On the 26th of March, the Associated Press reported that, "Gov. Andrew Cuomo of New York has said that if all of his sweeping, expensive measures to stem the coronavirus saved one life, it would be worth it." This surely must be hyperbole, but he has also said, "We’re not going to accept a premise that human life is disposable… And we’re not going to put a dollar figure on human life." At the same time, it seems that there is an increasing call in public discourse for a sensible weighing of the pros and cons of "lockdown" measures, which I suspect anyone reading this blog would agree is a necessary component of good decision making. If Cuomo's sentiment about the value of life is shared among decision makers and the public, how do we get our benefit-cost message across in an effective way, that can actually improve the quality of public decision making, at this particular moment, in this particular context?

The U.S. Environmental Protection Agency (EPA) has a long history of providing comprehensive guidance for conducting economic analyses, including benefit-cost analyses for environmental regulations. Much of that guidance is distilled in the EPA’s Guidelines for Preparing Economic Analyses, which was first released in 1983. The Guidelines are a mix of theory, empirical evidence, and practical recommendations and directives for ensuring the agency is providing the best available economic science for policy makers to consider when making decisions about regulatory actions.

Being in the SBCA is great because it connects me with so many very smart people who care about public policy and benefit-cost analysis. This value was illustrated by the rapid rate at which the SBCA network began to exchange ideas and estimates about the benefits and costs of interventions to address the COVID-19 situation. As these ideas start to work their way into the more general media, I wanted to share a few observations with readers of On Balance about the challenges facing our community in conducting and interpreting these benefit-cost analyses.

First, given how little we know about COVID-19, the first set of analyses will be preliminary and reflect a higher level of imprecision than analyses of diseases and interventions where we have more history. Nevertheless, these initial responses are essential for informing public policy. Policy makers are going to have to make decisions. They should have the benefit of the best available analyses, even if those analyses will get more accurate as the underlying estimates and assumptions used to produce them. The key here is to inform current decision-making and to then update the analyses as more evidence becomes available in order to inform future decision making.

Currently, e-cigarette supporters and opponents are passionately debating what regulations to impose on the products, if any. These debates have been playing out in legislative chambers across the United States, ranging from city halls to Congress, and in federal agencies including the Food and Drug Administration (FDA). Proponents who argue for no or little regulation maintain that e-cigarettes save lives by helping people quit smoking. Opponents, meanwhile, argue that e-cigarettes themselves are addicting teenagers to nicotine.

How much impact is your economic appraisal leaving out?” This is the perennial question that CBA practitioners face when putting forward their results of, normally, a poorly performing project. In investment appraisal, my area of work, the question is often decisive. I presume the same applies to CBA practice in policy appraisal.

Outer space probes, radio telescopes, large particle accelerators, genomic platforms, and similar entities are fascinating focal points of intellectual curiosity and discovery.  While we marvel at what we learn from them, we can be taken aback by their costs.  The $150 billion cost for the International Space Station has been shared by taxpayers in the United States, Europe, Russia, Japan, and Canada.  The Large Hadron Collider near Geneva, Switzerland that enabled the 2012 discovery of the elusive Higgs Boson is estimated to cost about 13.5 billion Euros over the 1993-2025 period for taxpayers in the participating countries.  According to a recent article in The Economist, proposals are being made to build new infrastructures: A Future Circular Collider in Switzerland, an International Linear Collider in Japan, and a Circular Electron-Position Collider in China. Such are the topic of Massimo Florio’s book, Investing in Science: Social Cost-Benefit Analysis of Research Infrastructures.  In it, he demonstrates that benefit-cost analysis (BCA) can be useful in answering the question:  Are these costly research infrastructures worth it?  He draws upon his substantial experience to adapt the traditional framework to the specific characteristics of research infrastructure (RI).  He identifies elements common to RIs, describes how they can be measured and valued, and gives examples from work that he and others have done. This pioneering book fills a gap in that such large-scale investments in science only infrequently have been evaluated using BCA.

Sometimes conferences actually do stimulate research that otherwise might not be done. Six years ago, I was enjoying a breakfast conversation at the SBCA annual research conference with our immediate past president, Clark Nardinelli. At that time, he was overseeing the Regulatory Impact Analysis (RIA) of Federal Drug Administration (FDA) rules implementing the Food Safety Modernization Act, which included provisions to reduce the risks posed to people and pets from adulterated pet food. He complained that, unlike the case of human mortality risks, he had no sound basis for monetizing changes in mortality risks for dogs and other pets. As dogs do not freely make tradeoffs between risks and wages in labor markets, I suggested that finding a value of statistical dog life would likely require a contingent valuation study. Would his unit provide the approximately $50 thousand dollars needed to do the contingent valuation survey? Unfortunately, he had nothing but praise for the suggestion.

So, you've done this great research, had this novel idea, attended a phenomenal event, or read a paradigm-shifting book, and you want to enlighten everyone in the benefit-cost analysis community.

Yes, we absolutely want your blog at the Society for Benefit-Cost Analysis.

This post describes a new article forthcoming in the Journal of Benefic Cost Analysis, “When Benefit-Cost Analysis Becomes Optional: Regulatory Analysis at the Consumer Product Safety Commission in the CPSIA Era.” The article describes a familiar scenario for practitioners of regulatory benefit cost analysis: a high impact event followed by swift and forceful congressional action. In the Consumer Product Safety Commission (CPSC) case, the high impact event was a series of product recalls involving toys contaminated with lead. Congress’s response was to pass the Consumer Product Safety Improvement Act (CPSIA) and require several rulemakings.

Applying benefit-cost analysis to homeland security regulations and related applications is difficult, in part due to issues in measuring security or risk avoided (Roberts, 2019; Farrow and Shapiro, 2009). The Office of University Programs within the Department of Homeland Security (DHS) asked our team of benefit-cost, decision, and risk analysts to evaluate changes in their security practices based on DHS funded research and development (R&D) projects over the last 15 years. Initial results have been published in von Winterfeldt, et al. (2019) with additional submissions planned for peer reviewed journals.

Policymakers are called to act in the present to protect the public against future risks while operating under the constraints of doing so in an economically efficient yet effective manner. Unfortunately, these risks tend to present the most difficulty for traditional analytical tools in support of policymaking. This post describes a recently published article, “Dynamic Benefit-Cost Analysis for Uncertain Futures,” co-authored with Susan E. Dudley, Brian F. Mannix, and Christopher Carrigan as part of the open access Symposium on Analysis for Uncertain Futures in the Journal of Benefit Cost Analysis. The article explores the challenges “uncertain futures” pose for analytical tools to satisfactorily support policymaking and proposes the use of “dynamic benefit-cost analysis” frameworks as a necessary approach to address these challenges.
