Using value of statistical life for the ex ante evaluation of transport policy options: a discussion based on ethical theory

This paper aims to discuss a number of questions that are highly important for the ex ante evaluation of the safety impacts of transport policy options, from the perspective of ethical theory: (1) Is it morally OK to express prevention on acceptance of fatalities or risks in monetary terms? (2) How useful is the concept of the value of a statistical life (VOSL) for ex ante evaluations of transport policy options? (3) What are the pros and cons of pricing protection of lives or prevention of risks in ex ante evaluations? (4) Which methods are available for expressing (protection of) human lives in monetary terms, and what are the main related methodological discussions? (5) Are all safety-related costs generally included in ex ante evaluations of the safety impacts of transport policy options, and if not: what is the relevance of excluded costs categories from an ethical perspective? (6) How important is the distribution of safety effects from an ethical perspective? The answer to the first question highly depends on the ethical theory that is used. With respect to question 2 we think that the VOSL is a useful concept, but that its application is not straightforward, for several reasons. Thirdly we think that probably pricing safety improves the quality of decision making, but to the best of our knowledge there is no research to underpin this expectation. The answer to question 4 is that several methods exist to estimate the value of a statistical life (VOSL), willingness-to-pay (WTP) methods being the most common category of methods. However, several methodological issues arise that make estimates of VOSL less straightforward. With respect to question 5 we conclude that behaviour-related avoidance costs are often overlooked and that these costs are relevant from an ethical perspective because the freedom to move and the freedom to participate in activities are challenged. Finally the answer to question 6 is that from an ethical perspective, in terms of the evaluation of policy measures, it might matter which groups of the population are the victims of the transport system, or are at risk. Egalitarian theories as well as sufficientarianism are useful theories to discuss distribution effects. Different theories conclude differently. © 2012 The Author(s)

Toleration, Reasonableness, and Power

This chapter explores Rainer Forst’s justification-centric view of nondomination toleration. This view places an idea of equal respect and a corresponding requirement of reciprocal and general justification at the core of non-domination toleration. After reconstructing this view, this chapter addresses two issues. First, even if this idea of equal respect requires the limits of non-domination toleration to be drawn in a manner that is equally justifiable to all affected people, equal justifiability should not be understood in terms of Forst’s requirement of reciprocal and general acceptability. Second, for the equal justifiability of relevant constraints to ensure non-domination outcomes, discursive equality must be understood in substantive, purchase-sensitive terms. This means that a justification-centric view of non-domination toleration stands or falls with the participation value of what it regards as the standards of justification. This places reasonably contested matters of value at the heart of such views

'Why be moral?’: how to take the question seriously (and why) from a Kantian perspective

Appropriately specified, the question, 'why be moral?', addresses important and legitimate topics of a broadly meta-ethical nature. The aim of the paper is to use this question as a dialectical tool, in order to identify the core theoretical commitments of Kant'sethics. Becausewell-foundedworrieshavebeenraised about the question itself, I consider these first. The purpose of this preliminary discussion is to determine the sort of question we are dealing with and to introduce the main topics for discussion

Social disappointment explains chimpanzees' behaviour in the inequity aversion task

Chimpanzees' refusal of less-preferred food when an experimenter has previously provided preferred food to a conspecific has been taken as evidence for a sense of fairness. Here, we present a novel hypothesis-the social disappointment hypothesis-according to which food refusals express chimpanzees' disappointment in the human experimenter for not rewarding them as well as they could have. We tested this hypothesis using a two-by-two design in which food was either distributed by an experimenter or a machine and with a partner present or absent. We found that chimpanzees were more likely to reject food when it was distributed by an experimenter rather than by a machine and that they were not more likely to do so when a partner was present. These results suggest that chimpanzees' refusal of less-preferred food stems from social disappointment in the experimenter and not from a sense of fairness
