Rear Visibility and Some Unresolved Problems for Economic Analysis (With Notes on Experience Goods)

Abstract: In 2014, the National Highway Traffic Safety Administration finalized its rear visibility regulation, which requires cameras in all new vehicles, with the goal of allowing drivers to see what is behind them and thus reducing backover accidents. In 2018, the Trump administration embraced the regulation. The rear visibility rule raises numerous puzzles. First: Congress’ grant of authority was essentially standardless – perhaps the most open-ended in all of federal regulatory law. Second: It is not easy to identify a market failure to justify the regulation. Third: The monetized costs of the regulation greatly exceeded the monetized benefits, and yet on welfare grounds, the regulation can plausibly be counted as a significant success. Rearview cameras produce a set of benefits that are hard to quantify, including increased ease of driving, and those benefits might have been made a part of “breakeven analysis,” accompanying standard cost-benefit analysis. In addition, rearview cameras significantly improve the experience of driving, and it is plausible to think that in deciding whether to demand them, many vehicle purchasers did not sufficiently anticipate that improvement. This is a problem of limited foresight; rearview cameras are “experience goods.” A survey conducted in 2019 strongly supports this proposition, finding that about 56 percent of consumers would demand at least $300 to buy a car without a rearview camera, and that fewer than 6 percent would demand $50 or less. Almost all of that 6 percent consists of people who do not own a car with a rearview camera. (The per-person cost is usually under $50.) These conclusions have general implications for other domains in which regulation has the potential to improve social welfare, even if it fails standard cost-benefit analysis; the defining category involves situations in which people lack experience with a good whose provision might have highly beneficial welfare effects.

Cost-Benefit Analysis without Analyzing Costs or Benefits: Reasonable Accommodation, Balancing, and Stigmatic Harms

Abstract: Is an accommodation “reasonable,” under the Americans with Disabilities Act, if and only if the benefits are roughly proportional to the costs? How should benefits and costs be assessed? Should courts asks about how much disabled employees are willing to pay to obtain the accommodation, or instead how much they would have to be paid not to have the accommodation? How should stigmatic or expressive harms be valued? This essay, written for a symposium on the work of Judge Richard A. Posner, engages these questions in a discussion of an important opinion in which Judge Posner denied accommodations involving the lowering of a sink in a kitchenette and a request for telecommuting. The problem with the analysis in that opinion is that it does not seriously analyze either costs or benefits. A general lesson is that while cost-benefit balancing can helpfully discipline unreliable intuitions about the effects of requested accommodations, it can also incorporate those intuitions. Another lesson is that stigmatic harms and daily humiliations deserve serious attention as part of the inquiry into which accommodations are reasonable, and that the removal of those harms and humiliations can create real benefits. Adequate cost-benefit analyses must attempt to measure and include those benefits. Richard Posner has been a colleague and a friend for over a quarter-century. Over the years, I have learned that there is one thing he isn’t: Sentimental. A celebration of his years on the bench inevitably invites not only sentimentality but also a lot of applause; and we should certainly pause for some.

The party was dominated by George Stigler, a Nobel Prize winner-to-be and a major figure at the university at the time. Stigler asked me what I taught, and I responded that I taught Social Security and Welfare Law, at which point Stigler began to cast cheerful, contemptuous ridicule on the subject. In Stigler’s view, no one in America was poor, because even a little money ($7 a week, if memory serves) could go a very long way. This position seemed to me not only preposterous but also offensive, and I tried to respond; but Stigler was of course Stigler, and in addition to being a terrific debater, he wasn’t always a nice man. Seeing my distress, Posner came to the

There Is Nothing that Interpretation Just Is

Abstract: Some people believe that the very idea of interpretation requires judges to adopt a particular method for interpreting the Constitution. The problem with this view is that in constitutional law, the general idea of interpretation is compatible with a range of different approaches, and among them, none is mandatory, in the sense of having some unique or privileged connection with the general idea. Any particular approach must be defended on the ground that it would make our constitutional order better rather than worse. No one should doubt that there are legitimate questions about the institutional capacities of judges, and about the virtues and vices of a deferential role on their part; the answers to those questions can motivate a view about constitutional interpretation. But they do not depend on an understanding of what interpretation necessarily requires.

The behaviour change wheel: a new method for characterising and designing behaviour change interventions.

Abstract: Improving the design and implementation of evidence-based practice depends on successful behaviour change interventions. This requires an appropriate method for characterising interventions and linking them to an analysis of the targeted behaviour. There exists a plethora of frameworks of behaviour change interventions, but it is not clear how well they serve this purpose. This paper evaluates these frameworks, and develops and evaluates a new framework aimed at overcoming their limitations. A systematic search of electronic databases and consultation with behaviour change experts were used to identify frameworks of behaviour change interventions. These were evaluated according to three criteria: comprehensiveness, coherence, and a clear link to an overarching model of behaviour. A new framework was developed to meet these criteria. The reliability with which it could be applied was examined in two domains of behaviour change: tobacco control and obesity. Nineteen frameworks were identified covering nine intervention functions and seven policy categories that could enable those interventions. None of the frameworks reviewed covered the full range of intervention functions or policies, and only a minority met the criteria of coherence or linkage to a model of behaviour. At the centre of a proposed new framework is a 'behaviour system' involving three essential conditions: capability, opportunity, and motivation (what we term the 'COM-B system'). This forms the hub of a 'behaviour change wheel' (BCW) around which are positioned the nine intervention functions aimed at addressing deficits in one or more of these conditions; around this are placed seven categories of policy that could enable those interventions to occur. The BCW was used reliably to characterise interventions within the English Department of Health's 2010 tobacco control strategy and the National Institute of Health and Clinical Excellence's guidance on reducing obesity. Interventions and policies to change behaviour can be usefully characterised by means of a BCW comprising: a 'behaviour system' at the hub, encircled by intervention functions and then by policy categories. Research is needed to establish how far the BCW can lead to more efficient design of effective interventions.

International Norm Dynamics and Political Change

Abstract: Norms have never been absent from the study of international politics, but the sweeping “ideational turn” in the 1980s and 1990s brought them back as a central theoretical concern in the field. Much theorizing about norms has focused on how they create social structure, standards of appropriateness, and stability in international politics. Recent empirical research on norms, in contrast, has examined their role in creating political change, but change processes have been less well-theorized. We induce from this research a variety of theoretical arguments and testable hypotheses about the role of norms in political change. We argue that norms evolve in a three-stage “life cycle” of emergence, “norm cascades,” and internalization, and that each stage is governed by different motives, mechanisms, and behavioral logics. We also highlight the rational and strategic nature of many social construction processes and argue that theoretical progress will only be made by placing attention on the connections between norms and rationality rather than by opposing the two.

Risk as Feelings

Abstract: Virtually all current theories of choice under risk or uncertainty are cognitive and consequentialist. They assume that people assess the desirability and likelihood of possible outcomes of choice alternatives and integrate this information through some type of expectation-based calculus to arrive at decision. The authors propose an alternative theoretical perspective, the risk-as-feelings hypothesis, that highlights the role of affect experienced at the moment of decision making. Drawing on research from clinical, physiological, and other subfield of psychology, they show that emotional reactions to risky situations often drive behavior. The risk-as-feelings hypothesis is shown to explain a wide range of phenomena that have resisted interpretation in cognitive-consequentialist terms.

A perspective on judgment and choice: Mapping bounded rationality.

Abstract: Early studies of intuitive judgment and decision making conducted with the late Amos Tversky are reviewed in the context of two related concepts: an analysis of accessibility, the ease with which thoughts come to mind; a distinction between effortless intuition and deliberate reasoning. Intuitive thoughts, like percepts, are highly accessible. Determinants and consequences of accessibility help explain the central results of prospect theory, framing effects, the heuristic process of attribute substitution, and the characteristic biases that result from the substitution of nonextensional for extensional attributes. Variations in the accessibility of rules explain the occasional corrections of intuitive judgments. The study of biases is compatible with a view of intuitive thinking and decision making as generally skilled and successful.
