Public pensions,family allowances and endogenous demographic change

In addition to an old-age insurance system which redistributes income from the young to the old, family allowances build a further redistributive system which typically favors younger and burdens older generations. Family allowances have two main tasks: first, child allowances offer an incentive for child-bearing which influences fertility in an economy. Second, subsidies which ease the financial burden of a child's education guarantee a higher average level of productive skills and therefore enhance net domestic product. If individual demand for having and educating children leads to an impact on the economic system as a whole, we have external effects. In such a case, corrective taxation (Pigouvian tax) should be considered.Earlier versions of this paper were presented at conferences in Bergen, Dublin, Gmunden, Oldenburg and Vienna. The paper benefitted greatly from discussions with participants of these conferences and from the suggestions of two anonymous referees of this journal.

Development Mobilities: Identity and Authority in an Angolan Development Programme

This ethnographic essay considers how international non-governmental organisations are able to make claims to authoritative knowledge about development work by offering the transnational mobilities of their staff members as evidence. I examine how one professional's biography—his trajectory from Angola to Britain and back again—was differentially presented to external donors and internal staff members as befitting the institutional needs of an international good governance intervention in Angola. These presentations reflect a commoditisation of the cosmopolitanism of professionals' histories in the service of development as a regime of mobility. I argue that, in this development regime, a global hierarchy prevents some individual professionals, particularly those from developing nations, from realising the same benefits of their cosmopolitan mobility as professionals from industrialised nations. While one of mobility studies' many strengths is that it highlights global interconnectedness, social scientists should not read equality in these interconnections but examine how patterns of transnational mobility may produce and reproduce global structures of inequality.     

American income inequality across economic and geographic space, 1970–2010

This analysis examines the spatial clustering of income inequality and its socioeconomic correlates at the meso-scale over the past four decades. Cluster analysis is used to group N = 3078 counties into five inequality clusters; and multinomial logistic regression is used to assess the effects of socioeconomic correlates. High and extreme inequality places are concentrated in large metropolitan centers, high amenity rural areas, and parts of the Great Plains and Mountain West. They tend to have better socioeconomic outcomes, with fewer at-risk populations, higher incomes, lower poverty, and greater economic participation. Unequal places are more specialized in high-skill finance and professional services, and in energy-based mining. By contrast, equality places are associated with low-skill services, education and health services, manufacturing, and stable farm economies.     

Risk aversion in n-person bargaining

Relations between risk properties of Pareto optimal n-person bargaining solutions are studied. The (weak) worse alternative property, risk sensitivity property, and risk profit opportunity property are considered, in particular relations between these properties, and between these properties and other properties such as independence of irrelevant alternatives and individual monotonicity. A distinction is made between bargaining games where all Pareto optimal outcomes are riskless, and bargaining games where Pareto optimal outcomes may represent the utilities of lotteries between riskless alternatives. In the first mentioned case, more general results can be obtained.     

A note on optimum linear feature extraction for gaussian populations with equal covariances and equal a priori probabilities

We consider the linear feature selection problem of obtaining a nonzero 1 × n matrix B which minimizes the probability of misclassification based on the Bayes decision rule applied to the random variable Y = BX, where X is a random n-vector arising from one of m Gaussian populations with equal covariances and equal apriori probabilities. It is shown that the optimal B satisfies a fixed point equation B = F(B) which can be solved by successive substitution.     

THE USE OF MODERATED REGRESSION IN JOB REDESIGN DECISIONS*

This paper describes the use of moderated regression in job redesign decisions. The procedures outlined are intended to augment the job redesign strategy described by Hackman and his colleagues. Different regression models based on a theory of job design are shown to lead to different job redesign decisions. Comparisons are also made between the moderated regression procedures and the more commonly used subgroups analysis.     

Longitudinal neural and behavioral trajectories of charity contributions across adolescence

This study examined the development of prosocial charity donations and neural activity in the ventral striatum when gaining rewards for self and for charity. Participants 10–22 years (95% European heritage) participated in three annual behavioral-fMRI waves (T1: n = 160, T2: n = 167, T3: n = 175). Behaviorally, donations to charity as measured with an economic Dictator Game increased with age. Perspective taking also increased with age. In contrast, self-gain and charity-gain enjoyment decreased with age. Ventral striatum activity was higher for rewards for self than for charity, but this difference decreased during adolescence. Latent growth curve models revealed that higher donations were associated with a smaller difference between ventral striatum activation for self and charity. These findings show longitudinal brain–donations associations in adolescence.
