Sickness and disability benefit programmes: What is driving policy convergence?

In this paper we explore the reasons for the apparent convergence in sickness and disability policies across the OECD, asking whether and to what extent policy convergence should be seen as a product of policy learning. We conclude that convergence is the result of policy imitation more than policy learning and that learning (from past mistakes) is more likely within countries than across borders. Given limited evidence on what really "works", when it comes to designing policies that both provide adequate income security and still encourage labour-force participation, governments look abroad or to bodies like the OECD for possible models and ideas to underlie a reform. However, translating those ideas into workable policies requires great sensitivity to the institutional and political-economic context — especially the role of the social partners and the nature of policies in existence. When it comes to policy implementation, such contextual learning may be crucial.     

What difference do alternative immigration and integration levels make to Western Europe?

The population of Western Europe (EC plus EFTA) is seen as consisting of three sub-populations: the natives, the East-European immigrants, and the non-European immigrants. Different immigration levels assumed add to the non-native populations while different levels of integration describe the transition intensities from a non-native to a native category. Alternative multi-state population projections to 2050 based on six scenarios show that (1) in the case of no further immigration the total population of Western Europe will start to decline after 2010; (2) the rate of integration influences the future size of the non-European population much more than alternative levels of immigration; (3) in the long run the Eastern Europeans will be quantitatively insignificant; (4) the Western European population is bound to significant population aging no matter what happens with immigration; and (5) in the short to medium run immigrants contribute to the alleviation of the pension burden.La population d'Europe occidentale (CE et AELE) est décomposée en trois sous-populations: les natifs, les immigrants originaires d'Europe de l'Est, et les immigrants originaires du reste du monde. Les populations non-natives augmentent sous l'effet de divers niveaux d'immigration tandis que les intensités de passage d'une catégorie non-native à native sont décrites par différents niveaux d' intégration. Des projections de population jusqu'en 2050 dans ces divers états, basées sur six scénarios, montrent que: (1) la population totale de l'Europe occidentale commencerait à baisser après 2010, dans le cas d'un arrêt de l'immigration; (2) le taux d' intégration influencerait la taille future de la population non-européenne beaucoup plus fortement que le niveau d'immigration; (3) dans le long terme, les Européens de l'Est serait en nombre très réduit; (4) la population d'Europe occidentale connaîtra un vieillissement important de sa population, quelque soit ses flux d'immigrants; et (5) dans le court et le moyen terme les immigrants contribueraient à alléger le poids des retraites.     

Adjustments of public pension schemes in twelve industrialized countries: Possible answers to population ageing

This article analyses the impact of population dynamics on future public pension expenditure in twelve industrialized countries. Whereas previous studies have mainly emphasized ageing effects, this study looks into the consequences of changing marital status structures as well. Old age pensions, disability, and survivor's pensions are investigated. Various sets of demographic and pension scenarios are formulated for the projections, dealing with changes in demographic, labour force and pension system variables in the future. The analyses show that there can be no adequate demographic response to rising pension costs caused by population ageing at the horizon 2030. Neither an increase in fertility nor an inflow of migrants can rejuvenate national populations, unless fertility and/or migration reach unrealistically high levels. Instead, substantial reductions of the public pension burden have to be sought in socioeconomic measures.Cet article analyse l'impact des dynamiques de population sur les dépenses de retraite à venir dans douze pays industrialisés. Alors que des études antérieures avaient surtout insisté sur les effets du vieillissement, cet article examine les conséquences des changements dans les structures par état matrimonial. Les retraites pour les âges avancés, l'invalidité et les retraites du conjoint survivant sont explorés. Différents ensembles de scénarios démographiques et de retraite sont formulés par des projections, portant sur les changements démographiques, les changements dans la population active et dans les systémes de retraite qui peuvent intervenir dans le futur. Les analyses montrent qu'il n'y a pas de réponse démographique adéquate au coûts croissants des retraites, causés par le vieillissement démographique à l'horizon de l'an 2030. Ni un accroissement de la fécondité ni un afflux de migrants ne peuvent rajeunir les populations nationales, à moins que la fécondité et/ou la migration n'atteignent de très hauts niveaux peu réalistes. Au contraire, des réductions substantielles du poids des retraites publiques doivent être recherchées dans des mesures socio-économiques.     

Popularity kills the Talentstar? Einflussfaktoren auf Superstargeh?lter in der NBA

The observation that top athletes earn top salaries is well known. The (controversial) debate on superstar-salaries is mainly based on the two competing but equally plausible explanations outlined by Rosen (Am Eco Rev 71(5):845–858, 1981) and Adler (Am Eco Rev 75(1):208–212, 1985). Although both authors illustrate conclusive arguments, the discussion which of these two theories is more adequate in explaining superstar salaries still remains unsolved. The present paper analyzes salary information from the National Basketball Association (NBA) to explore the effect of Rosen’s (Am Eco Rev 71(5):845–858, 1981) talent approach versus the network and media approach by Adler (Am Eco Rev 75(1):208–212, 1985). Using innovative indicators for talent (draft position) and popularity (Facebook fans) in one model, the results of our preferred quantile regression specification indicates that player talent is stronger related to earning than popularity, particularly in the upper quantiles.     

Means‐End Behavior in Young Infants: The Interplay of Action Perception and Action Production

In 2 experiments, the interplay of action perception and action production was investigated in 6‐month‐old infants. In Experiment 1, infants received 2 versions of a means‐end task in counterbalanced order. In the action perception version, a preferential looking paradigm in which infants were shown an actor performing means‐end behavior with an expected and an unexpected outcome was used. In the action production version, infants had to pull a cloth to receive a toy. In Experiment 2, infants' ability to perform the action production task with a cloth was compared to their ability to perform the action production task with a less flexible board. Finally, Experiment 3 was designed to control for alternative low‐level explanations of the differences in the looking times toward the final states presented in Experiment 1 by only presenting the final states of the action perception task without showing the initial action sequence. Results obtained in Experiment 1 showed that in the action perception task, infants discriminated between the expected and the unexpected outcome. This perceptual ability was independent of their actual competence in executing means‐ end behavior in the action production task. Experiment 2 showed no difference in 6‐month‐olds' performance in the action production task depending on the properties of the support under the toy. Similarly, in Experiment 3, no differences in looking times between the 2 final states were found. The findings are discussed in light of theories on the development of action perception and action production.     

Latent Models of Family Processes in African American Families: Relationships to Child Competence,Achievement, and Problem Behavior

This study explored the assessment of family processes for a sample of African American kindergarten children, parents, and teachers involved in the EARLY ALLIANCE prevention trial. Using modified versions of the Family Assessment Measure, the Family Adaptability and Cohesion Evaluation Scales, the Family Beliefs Inventory, and the Deviant Beliefs measure, internal consistency analyses along with exploratory and confirmatory factor analyses provided empirical support for a Cohesion factor (cohesion and communication), a Structure factor (support and organization), a Beliefs factor (on family purpose and child development), and a Deviant Beliefs factor. Regression analyses examined the relationship of these measures of family processes to child social and academic competence, problem behavior, and early reading achievement. Family Structure (support and organization) was consistently related to parent‐ and teacher‐reported competence and behavioral outcomes, providing support for this construct as an important aspect of family process. Family Cohesion and communication, along with Beliefs, were also related to youth competence and behavior. None of the family process variables added a unique contribution to the influence upon achievement for these kindergarten children beyond the role of parental education and income. This work begins to examine specific dimensions of family processes and their relationships to important adaptive and less adaptive child outcomes. Other dimensions may be identified and examined in future research with families of color.     

THE PAYOFF TO CONSISTENCY IN PERFORMANCE

This study investigates whether firms are willing to pay higher wages to workers who demonstrate consistent performance than to those whose performance is more volatile. A formal model reflects a production technology view, assuming the law of diminishing marginal product. This model suggests that a more consistent worker produces higher expected output and therefore receives a higher wage. The test of the model uses data from the National Basketball Association. The empirical data support the model: Players whose performances were more consistent than the performances of other players received higher wages on average. (JEL D41, J31, M52, Z20)     

Endogenous fertility,altruistic behavior across generations,and social security systems

The present paper explores the impact of an intergenerational externality on private fertility decisions, under a pay-as-you-go social security system. The analysis is performed in the framework of a steady state growth model, with overlapping generations. To explain why households have children, altruism between parents and children is assumed. Surprisingly, the effects of altruism are not symmetric. The private fertility decisions are optimal only if children love their parents, because children then make private transfers at exactly the right level.Comments of participants of a seminar on economic theory of Prof. K.
