Positional goods and legal orderings
People consume because others consume, maintained Veblen in 1899. More recently, theoretical, empirical and experimental articles have argued that people constantly compare themselves to their environments and care greatly about their relative positions. Given that competition for positions may produce social costs, we adopt a Law and Economics approach (i) to suggest legal remedies for positional competition, and (ii) to argue that, because legal relations are characterized in turn by positional characteristics, such legal remedies do not represent âfree lunchesâ
Content, cost and context: a framework for understanding human signaling systems
Humans frequently perform extravagant and seemingly costly behaviors, such as widely sharing hunted resources, erecting conspicuous monumental structures, and performing dramatic acts of religious devotion. Evolutionary anthropologists and archeologists have used signaling theory to explain the function of such displays, drawing inspiration from behavioral ecology, economics, and the social sciences. While signaling theory is broadly aimed at explaining honest communication, it has come to be strongly associated with the handicap principle, which proposes that such costly extravagance is in fact an adaptation for signal reliability. Most empirical studies of signaling theory have focused on obviously costly acts, and consequently anthropologists have likely overlooked a wide range of signals that also promote reliable communication. Here, we build on recent developments in signaling theory and animal communication, developing an updated framework that highlights the diversity of signal contents, costs, contexts, and reliability mechanisms present within human signaling systems. By broadening the perspective of signaling theory in human systems, we strive to identify promising areas for further empirical and theoretical work
Visible inequality breeds more inequality
Experiments suggest that when people can see wealth inequality in their social network, this propels further inequality through reduced cooperation and reduced social connectivity. News & Views comment on Nishi et al, Nature 526, 2015, p. 426-429
Avoiding or restricting defectors in public goods games?
When creating a public good, strategies or mechanisms are required to handle defectors. We first show mathematically and numerically that prior agreements with posterior compensations provide a strategic solution that leads to substantial levels of cooperation in the context of public goods games, results that are corroborated by available experimental data. Notwithstanding this success, one cannot, as with other approaches, fully exclude the presence of defectors, raising the question of how they can be dealt with to avoid the demise of the common good. We show that both avoiding creation of the common good, whenever full agreement is not reached, and limiting the benefit that disagreeing defectors can acquire, using costly restriction mechanisms, are relevant choices. Nonetheless, restriction mechanisms are found the more favourable, especially in larger group interactions. Given decreasing restriction costs, introducing restraining measures to cope with public goods free-riding issues is the ultimate advantageous solution for all participants, rather than avoiding its creation.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Neo-Aristotelian Naturalism and the Evolutionary Objection: Rethinking the Relevance of Empirical Science
Neo-Aristotelian metaethical naturalism is a modern attempt at naturalizing ethics using ideas from Aristotleâs teleological metaphysics. Proponents of this view argue that moral virtue in human beings is an instance of natural goodness, a kind of goodness supposedly also found in the realm of non-human living things. Many critics question whether neo-Aristotelian naturalism is tenable in light of modern evolutionary biology. Two influential lines of objection have appealed to an evolutionary understanding of human nature and natural teleology to argue against this view. In this paper, I offer a reconstruction of these two seemingly different lines of objection as raising instances of the same dilemma, giving neo-Aristotelians a choice between contradicting our considered moral judgment and abandoning metaethical naturalism. I argue that resolving the dilemma requires showing a particular kind of continuity between the norms of moral virtue and norms that are necessary for understanding non-human living things. I also argue that in order to show such a continuity, neo-Aristotelians need to revise the relationship they adopt with empirical science and acknowledge that the latter is relevant to assessing their central commitments regarding living things. Finally, I argue that to move this debate forward, both neo-Aristotelians and their critics should pay attention to recent work on the concept of organism in evolutionary and developmental biology
Growth characteristics in individuals with osteogenesis imperfecta in North America: results from a multicenter study.
PurposeOsteogenesis imperfecta (OI) predisposes people to recurrent fractures, bone deformities, and short stature. There is a lack of large-scale systematic studies that have investigated growth parameters in OI.MethodsUsing data from the Linked Clinical Research Centers, we compared height, growth velocity, weight, and body mass index (BMI) in 552 individuals with OI. Height, weight, and BMI were plotted on Centers for Disease Control and Prevention normative curves.ResultsIn children, the median z-scores for height in OI types I, III, and IV were -0.66, -6.91, and -2.79, respectively. Growth velocity was diminished in OI types III and IV. The median z-score for weight in children with OI type III was -4.55. The median z-scores for BMI in children with OI types I, III, and IV were 0.10, 0.91, and 0.67, respectively. Generalized linear model analyses demonstrated that the height z-score was positively correlated with the severity of the OI subtype (Pâ<â0.001), age, bisphosphonate use, and rodding (Pâ<â0.05).ConclusionFrom the largest cohort of individuals with OI, we provide median values for height, weight, and BMI z-scores that can aid the evaluation of overall growth in the clinic setting. This study is an important first step in the generation of OI-specific growth curves
A probabilistic analysis of argument cogency
This paper offers a probabilistic treatment of the conditions for argument cogency as endorsed in informal logic: acceptability, relevance, and sufficiency. Treating a natural language argument as a reason-claim-complex, our analysis identifies content features of defeasible argument on which the RSA conditions depend, namely: change in the commitment to the reason, the reasonâs sensitivity and selectivity to the claim, oneâs prior commitment to the claim, and the contextually determined thresholds of acceptability for reasons and for claims. Results contrast with, and may indeed serve to correct, the informal understanding and applications of the RSA criteria concerning their conceptual dependence, their function as update-thresholds, and their status as obligatory rather than permissive norms, but also show how these formal and informal normative approachs can in fact align

Home-ownership as a social norm and positional good: subjective well-being evidence from panel data
Much attention has been devoted to examining the absolute benefits
of home-ownership (e.g. security and autonomy). This paper by contrast is
concerned with conceptualising and testing the relative benefits of homeownership;
those benefits that depend on an individualâs status in society.
Home-ownership has previously been analysed as a social norm, implying that
the relative benefits (costs) associated with being an owner (renter) are
positively related to relevant othersâ home-ownership values. The theoretical
contribution of this paper is to additionally conceptualise home-ownership as a
positional good, implying that the status of both home-owners and renters is
negatively related to relevant othersâ home-ownership consumption.
The empirical contribution of this paper is to quantitatively test for these relative
benefits in terms of subjective well-being. We run fixed effects regressions on
three waves of the British Household Panel Study. We find that i) a strengthening
of relevant othersâ home-ownership values is associated with increases
(decreases) in the subjective well-being of home-owners (renters), and ii) an
increase in relevant othersâ home-ownership consumption decreases the life
satisfaction of owners but has no effect for renters.
Overall our findings suggest that i) the relative benefit of home-ownership are
both statistically significant and of a meaningful magnitude, and ii) homeownership
is likely to be both a social norm and a positional good. Without
explicitly recognising these relative benefits, policymakers risk overestimating
the contribution of home-ownership to societal well-being
