Financial Regulation and Cost-Benefit Analysis: A Comment

Abstract: Many regulators have concluded that cost-benefit analysis is the best available method for capturing the welfare effects of regulations. It is therefore understandable that in recent years, some people have been interested in requiring financial regulators to engage in careful cost-benefit analysis of their regulations, and to proceed only if the benefits justify the costs. Ideas of this sort have played a significant role in judicial review of agency action, especially in cases involving the Securities and Exchange Commission. But it is important to distinguish the question whether courts should require cost-benefit analyses, and review them for arbitrariness, from the separate question whether financial regulators should produce such analyses. It is also important to understand that in some cases, cost-benefit analysis presents serious challenges for financial regulators. When agencies lack relevant information, and cannot project benefits (or costs), they can invoke established techniques to discipline the question whether and how to proceed. In particular, breakeven analysis plays a valuable role. Of course it remains possible that in rare cases, agencies have so little information that they cannot even use breakeven analysis. In such cases, it is not helpful to refer to the precautionary principle or to “expert judgment.” In such rare cases, the best that agencies may be able to do is to rely on some version of maximin, while also seeking to fill informational gaps over time.

Propiedad y Constitucionalismo

Abstract: El autor nos recuerda cuales son las funciones y ventajas de un sistema adecuado de derechos de propiedad y rescata la importancia de una redaccion constitucional adecuada para hacer que estos derechos politicos sean realmente efectivos. Con este fin ofrece a los lectores una serie de pautas a seguir, para evitar que se cometan errores catastroficos a traves de una regulacion mal enfocada, que no reconoce las condiciones constitucionales indispensables para la reforma de la democracia y el impulso del desarrollo economico.

Boundedly rational patients? Part 1: Health and patient mistakes in a behavioral framework

Abstract: During medical visits, the stakes are high for many patients, who are put in a position to make, or to begin to make, important health-related decisions. But in such visits, patients often make cognitive errors. Traditionally, those errors are thought to result from poor communication with physicians; complicated subject matter; and patient anxiety. To date, measures to improve patient understanding and recall have had only modest effects. This paper reviews the current literature on behavioral insights in the patient experience and argues that an understanding of those cognitive errors can be improved by reference to a behavioral science framework, which distinguishes between a "System 1" mindset, in which patients are reliant on intuition and vulnerable to biases and imperfectly reliable heuristics, and a "System 2" mindset, which is reflective, slow, deliberative, and detailed-oriented.

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.
