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.

The quality of electricity distribution is being more and more scrutinized by regulatory authorities, with explicit reward and penalty schemes based on quality targets having been introduced in many countries (France, Germany, Italy, UK,...). It is then of prime importance to know the cost of improving the quality for a distribution system operator. In this paper, we focus on one dimension of quality, the continuity of supply, and we estimated the cost of preventing power outages. For that, we make use of the parametric distance function approach, assuming that outages enter in the firm production set as an input, an imperfect substitute for maintenance activities and capital investment. This allows us to identify the sources of technical inefficiency and the underlying trade-­‐off faced by operators between quality and other inputs and costs. For this purpose, we use panel data on 92 electricity distribution units operated by ERDF (Electricité de France - Réseau Distribution) in the 2003–2005 financial years. Assuming a multi-output multi-input translog technology, we estimate that the cost of preventing one interruption varies substantily among the distribution units from 2.7 € to 15.7 €. Furthermore, as one would expect, marginal quality improvements tend to be more expensive as quality itself improves. [less ▲]

Many Belgian retire well before the statutory retirement age. Numerous exit routes from the labor force can be identified: old‐age pensions, conventional early retirement, disability insurance, and unemployment insurance are the most prominent ones. We analyze the retirement decision of Belgian workers adopting an option value framework, and pay special attention to the role of health status. We estimate probit models of retirement using data from SHARE. The results show that health and incentives matter in the decision to exit from the labor market. Based on these results, we simulate the effect of potential reforms on retirement. [less ▲]

We simulate different reform scenarios of the Belgian pension system using a micro-simulation approach. Using a rich administrative dataset with extensive information on individual earnings histories, we evaluate the impact of the scenarios for the individuals as well as the system as a whole. Our main metric for these analysis is the notion of accrued to date pension rights, i.e. the pensions rights that would be due if the system were shut down today and all accrued rights under current legislation were honoured. Our analysis illustrates that partial reforms have limited effects, both in distributional and in fiscal terms. To achieve more substantial effects, a more comprehensive approach is needed. Regional differences within the country are mostly due to differences in regional GDP rather than the pension system itself. [less ▲]

The paper provides a perspective on the development of the Belgian disability insurance system. Using both survey and administrative data, it sketches a picture of the (changing) factors leading towards disability, as well as the outcomes in terms of program participation. The paper shows the key role of integrating other forms of early retirement programs into the analysis. The main findings are an unspectacular trend in the number of DI beneficiaries over time combined with a strong expansion of (early-) retirement schemes. [less ▲]

Dans ce numéro de Regards économiques, nous présentons une mesure multidimensionnelle de la performance des Etats- providence de l’Union européenne. Cette mesure permet de comparer la performance des pays de l’Europe des 15 avec celle des 12 nouveaux membres; elle donne aussi la possibilité de tester l’hypothèse d’un éventuel dumping social; enfin elle peut être utilisée pour mieux appréhender la performance de la protection sociale de la Belgique et de ses composantes régionales.
