Preference purification and the inner rational agent:A critique of the conventional wisdom of behavioural welfare economics
Neoclassical economics assumes that individuals have stable and context-independent preferences, and uses preference-satisfaction as a normative criterion. By calling this assumption into question, behavioural findings cause fundamental problems for normative economics. A common response to these problems is to treat deviations from conventional rational-choice theory as mistakes, and to try to reconstruct the preferences that individuals would have acted on, had they reasoned correctly. We argue that this preference purification approach implicitly uses a dualistic model of the human being, in which an inner rational agent is trapped in an outer psychological shell. This model is psychologically and philosophically problematic
Do people really want to be nudged towards healthy lifestyles?
This paper assesses Thaler and Sunstein’s claim that policies that nudge individuals towards healthy lifestyles promote the welfare of those individuals, as judged by themselves. I argue that Thaler and Sunstein switch between two different interpretations of that clause. One interpretation gives the clause a wide range of applicability, but drains it of its content as a repudiation of paternalism. The other interpretation makes it more meaningful to say that people want to make the choices they are being nudged towards, but applies to a much narrower range of cases than Thaler and Sunstein have in mind
Awards, incentives and mutual benefit
Frey argues that if buyers and sellers of labour understand their relationship merely as exchange, workers’ intrinsic motivation can be impaired; this problem can be partially overcome by using awards as a supplementary reward mechanism. I argue that this proposal is self-defeating. In an economy that relies on the division of labour, it is an unavoidable fact that individuals are subject to the will of others; award-giving practices are merely camouflage. However, recognising this fact need not impair anyone’s sense of autonomy as a paid worker if participation in market exchanges is understood as expressing intentions for mutual benefit
Master crossover behavior of parachor correlations for one-component fluids
The master asymptotic behavior of the usual parachor correlations, expressing
surface tension as a power law of the density difference
between coexisting liquid and vapor, is analyzed for a
series of pure compounds close to their liquid-vapor critical point, using only
four critical parameters , , and ,
for each fluid.
... The main consequences of these theoretical estimations are discussed in
the light of engineering applications and process simulations where parachor
correlations constitute one of the most practical method for estimating surface
tension from density and capillary rise measurements
The feasibility of using pedometers and brief advice to increase activity in sedentary older women:a pilot study
Background: People over the age of 70 carry the greatest burden of chronic disease, disability and health care use. Participation in physical activity is crucial for health, and walking accounts for much of the physical activity undertaken by sedentary individuals. Pedometers are a useful motivational tool to encourage increased walking and they are cheap and easy to use. The aim of this pilot study was to evaluate the feasibility of the use of pedometers plus a theory-based intervention to assist sedentary older women to accumulate increasing amounts of physical activity, mainly through walking. Methods: Female participants over the age of 70 were recruited from primary care and randomised to receive either pedometer plus a theory-based intervention or a theory-based intervention alone. The theory-based intervention consisted of motivational techniques, goal-setting, barrier identification and self-monitoring with pedometers and daily diaries. The pedometer group were further randomised to one of three target groups: a 10%, 15% or 20% monthly increase in step count to assess the achievability and acceptability of a range of targets. The primary outcome was change in daily activity levels measured by accelerometry. Secondary outcome measures were lower limb function, health related quality of life, anxiety and depression. Results: 54 participants were recruited into the study, with an average age of 76. There were 9 drop outs, 45 completing the study. All participants in the pedometer group found the pedometers easy to use and there was good compliance with diary keeping (96% in the pedometer group and 83% in the theory-based intervention alone group). There was a strong correlation (0.78) between accelerometry and pedometer step counts i.e. indicating that walking was the main physical activity amongst participants. There was a greater increase in activity (accelerometry) amongst those in the 20% target pedometer group compared to the other groups, although not reaching statistical significance (p = 0.192). Conclusion: We have demonstrated that it is feasible to use pedometers and provide theory-based advice to community dwelling sedentary older women to increase physical activity levels and a larger study is planned to investigate this further.Publisher PDFPeer reviewe
Whiteness, Blackness and Settlement: Leisure and the Integration of New Migrants
At times of economic uncertainty the position of new migrants is subject to ever closer scrutiny. While the main focus of attention tends to be on the world of employment the research on which this paper is based started from the proposition that leisure and sport spaces can support processes of social inclusion yet may also serve to exclude certain groups. As such, these spaces may be seen as contested and racialised places that shape behaviour. The paper draws on interviews with White migrants from Poland and Black migrants from Africa to examine the normalising of whiteness. We use this paper not just to explore how leisure and sport spaces are encoded by new migrants, but how struggles over those spaces and the use of social and cultural capital are racialised
For the benefit of all? Developing a critical perspective in mega-event leverage
The purpose of this article is to bring to light the need for developing a critical leveraging perspective on mega-events and propose a research agenda that extends the focus of the leverage concept towards this direction. Current research on leverage focuses on the attainment and magnification of mega-event outcomes. A critical lens of inquiry however is needed to move forward and take into account the influence of power structures and social-ordering processes on developing and implementing strategic leveraging programs. Such a perspective can help examine if and how the benefits of mega-events are fairly delivered to host communities, equally distributed among stakeholders and then sustained, while negative impacts are minimised. Ten research themes are brought forward to help build a robust ground for a critical mega-event leveraging perspective
Cooperation, Norms, and Revolutions: A Unified Game-Theoretical Approach
Cooperation is of utmost importance to society as a whole, but is often
challenged by individual self-interests. While game theory has studied this
problem extensively, there is little work on interactions within and across
groups with different preferences or beliefs. Yet, people from different social
or cultural backgrounds often meet and interact. This can yield conflict, since
behavior that is considered cooperative by one population might be perceived as
non-cooperative from the viewpoint of another.
To understand the dynamics and outcome of the competitive interactions within
and between groups, we study game-dynamical replicator equations for multiple
populations with incompatible interests and different power (be this due to
different population sizes, material resources, social capital, or other
factors). These equations allow us to address various important questions: For
example, can cooperation in the prisoner's dilemma be promoted, when two
interacting groups have different preferences? Under what conditions can costly
punishment, or other mechanisms, foster the evolution of norms? When does
cooperation fail, leading to antagonistic behavior, conflict, or even
revolutions? And what incentives are needed to reach peaceful agreements
between groups with conflicting interests?
Our detailed quantitative analysis reveals a large variety of interesting
results, which are relevant for society, law and economics, and have
implications for the evolution of language and culture as well
