This paper investigates the relationship between the concept of activity (including both professional and nonprofessional) and cognitive functioning among older European individuals. In this research, we used data collected during the first wave of SHARE (Survey on Health, Ageing and Retirement in Europe), and a measurement approach known as stochastic frontier analysis, derived from the economic literature. SHARE includes a large population (n . 25,000) geographically distributed across Europe, and analyzes several dimensions simultaneously, including physical and mental health activity. The main advantages of stochastic frontier analysis are that it allows estimation of parametric function relating cognitive scores and driving factors at the boundary and disentangles frontier noise and distance to frontier components, as well as testing the effect of potential factors on these distances simultaneously. The analysis reveals that all activities are positively related to cognitive functioning in elderly people. Our results are discussed in terms of prevention of cognitive aging and Alzheimer’s disease, and regarding the potential impact that some retirement programs might have on cognitive functioning in individuals across Europe.

This paper analyzes the effect of retirement on cognitive functioning using two large scale surveys. On the one hand the HRS, a longitudinal survey among individuals aged 50+ living in the United States, allows us to control for individual heterogeneity and endogeneity of the retirement decision by using the eligibility age for Social Security as an instrument. On the other hand, a comparable international European survey, SHARE, allows us to identify the causal effect of retirement on cognitive functioning by using the cross-country differences in the age-pattern of retirement. The results highlight in both cases a significant negative, and quantitatively comparable, effect of retirement on cognitive functioning. Our results suggest that promoting labor force participation of older workers is not only desirable to insure the viability of retirement schemes, but it could also delay cognitive decline, and thus the occurrence of associated impairments at older age.

Une approche en termes de frontières d’effi cacité peut être utilisée pour étudier les relations entre les fonctions cognitives des personnes âgées de plus de 50 ans en Europe d’une part, et différents facteurs, plus particulièrement l’âge, l’éducation et l’exercice d’activités, professionnelles ou non, d’autre part. Le but est de construire une « frontière » correspondant au fonctionnement cognitif optimal que chacun des individus est censé atteindre étant donné son âge et son niveau d’éducation. À cette fi n, nous utilisons des données individuelles collectées durant la première vague de l’enquête internationale et interdisciplinaire Share de 2004, laquelle contient le résultat de tests cognitifs réalisés auprès de plus de 22 000 individus âgés, ainsi que des informations sur leur état de santé, mentale et physique, leur situation socio-économique, leur entourage familial, l’exercice d’activités professionnelles ou non professionnelles, l’isolement social et les performances cognitives individuelles mesurées à l’aide de tests. En plus du rôle fondamental joué par l’éducation face au vieillissement cognitif, le fait de rester en activité, ainsi que la pratique d’une activité non professionnelle ou d’activités physiques, vigoureuses ou modérées, sont positivement associés à la constitution des « réserves cognitives » individuelles. La mise à disposition des données des vagues successives de Share , prévues tous les deux ans auprès des mêmes individus, pourrait permettre de déterminer les liens de causalité subjacents. [less ▲]

This paper proposes the use of the stochastic frontier approach to analyse the relationship between cognitive performance, retirement and non-professional activities of the 50+ individuals using data from three surveys conducted in Europe (the Survey on Health, Ageing and Retirement in Europe and the English Longitudinal Survey on Ageing) and United States (the Health and Retirement Study). Next to the strong relationship between cognitive performance, age and education, this study highlights the negative effect of retirement and the positive impact of non-professional activities and social contacts.

The aim of this paper was to use a parametric stochastic frontier approach (coming from the economic literature) to explore the impact of the concept of activity (taken in a broad sense: i.e., including both professional and non-professional activities) on the constitution and the care of cognitive reserve among the European population aged 50 and up. For this purpose, we use individual data collected during the first wave of SHARE (Survey on Health, Ageing and Retirement in Europe) performed in 2004. The advantages of this survey were (1) it included a large population (n = 18,623) geographically distributed throughout Europe; and (2) it simultaneously analyzed several dimensions (physical and mental health, mobility, occupational activities, socioeconomic status, etc.). Our results confirm the positive impact of occupational activities on the cognitive functioning of elderly people. These results are discussed in terms of the prevention of cognitive aging and Alzheimer’s disease, and more particularly of retirement policy issues. [less ▲]

On a longtemps pensé qu’en encourageant les départs anticipés à la retraite on libérait des postes de travail pour des jeunes inoccupés. Néanmoins, la Belgique compte aujourd’hui parmi les pays où les taux d’emploi des jeunes et des personnes âgées de plus de 50 ans sont des plus faibles parmi les pays industrialisés. Face au défi posé par le vieillissement de la population, l’augmentation du taux d’emploi, et plus particulièrement l’allongement de la vie active, apparaissent comme la seule solution. Dans cette note nous analysons les différentes voies de cessation d’activité et plaidons pour le démantèlement des mécanismes incitatifs qui favorisent les départs anticipés de la vie active. De même, nous plaidons pour la mise sur pied des programmes qui favorisent l’emploi des plus âgés, à l’image de ceux développés pour favoriser l’emploi des jeunes. La survie de toute l’architecture de la protection sociale en Belgique en dépend, et à fortiori celle de ses régions. [less ▲]

The purpose is to try to understand what is the real situation of families and individuals across countries and socio-economic categories. For those of them still at work we are interested to know how they are preparing for old days’ consumption, and, for those already retired, how they meet their old age needs. We know that for some of them, facing liquidity constraints or bad health, consumption will be restricted, whereas others will be able to save from their current income, while a third group will be composed of net dissavers. In this contribution, we are particularly interested in the distributive issues pertaining to these three dimensions taken together. In the first section we explain some data issues and methodological choices. The second section is devoted to the presentation of Lorenz curves and Gini coefficients by macro-regions and countries, and the third section to a comparative study of I-C-W distribution across age categories. Some conclusions and potential lines of research for the future end this contribution. [less ▲]

En Belgique, une proportion importante de travailleurs quittent la vie active avant d'atteindre l'âge de 60 ans. Dans cette étude nous analysons les conditions de vie de cette tranche de la population à l'aide d'une série d'indicateurs. Il apparaît que plus d'un quart d'entre eux sont "pauvres" selon le critère du seuil de 60% du revenu médian (15,6% au seuil de 50%) et ces observations sont confirmées quand on s'intéresse à la situation de ces mêmes personnes du point de vue patrimonial ou au travers d'indicateurs de pauvreté subjective ou de privation matérielle. Avec une population vieillissant à grands pas du fait de l'arrivée massive de la génération issue du "baby-boom" et de l'allongement de l'espérance de vie, on doit s'inquiéter des conditions dans lesquelles une partie de cette population vivra ces vieux jours.
