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.

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 ▲]

Most of the literature on the efficiency effects of regulatory reforms ignores the gradual nature of the implementation of these reforms. This article describes a new simple data manipulation that minimizes data requirements to measure econometrically the impact on efficiency of each stage of multi-stages regulatory reforms. The approach can easily be implemented using standard stochastic frontier software programs. It is illustrated with data on the Spanish port system, which went through a two-stage reform during the 1990s. [less ▲]

Monte Carlo experimentation is a well-known approach used to test the performance of alternative methodologies under different hypotheses. In the frontier analysis framework, whatever the parametric or non-parametric methods tested, experiments to date have been developed assuming single output multi-input production functions. The data generated have mostly assumed a Cobb–Douglas technology. Among other drawbacks, this simple framework does not allow the evaluation of DEA performance on scale efficiency measurement. The aim of this paper is twofold. On the one hand, we show how reliable two-output two-input production data can be generated using a parametric output distance function approach. A variable returns to scale translog technology satisfying regularity conditions is used for this purpose. On the other hand, we evaluate the accuracy of DEA technical and scale efficiency measurement when sample size and output ratios vary. Our Monte Carlo experiment shows that the correlation between true and estimated scale efficiency is dramatically low when DEA analysis is performed with small samples and wide output ratio variations.

We use the primary indicators of social inclusion proposed within the scope of the Open Method of Coordination (OMC) to situate Wallonia in the European Union (EU15) context. The results show that Wallonia stood in 2005 at the same level as Greece and was behind the EU15 level mainly regarding poverty and long-term unemployment rates. Groups at risk are single-parent families as well as unemployed and other inactive categories. Having at disposal these indicators for the years to come will be a must not only for the design but also for the evaluation of policies towards a better social cohesion. [less ▲]

The main objectives of project AG/01/116 were to further refine and validate the microsimulation model for social security, MIMOSIS, both by extending the data coverage and refining the modules as through a comparative study of how MIMOSIS is positioned in an international perspective and also by use of MIMOSIS for evaluation of (hypothetical) policy reforms.

Although the methods for measuring the extent of undeclared work are improving continuously, they still have shortcomings today. The statistical apparatus is not adapted to the present-day needs for mapping this phenomenon. The assignment is not simple either: making something visible that wants to remain hidden by definition. This article summarises a study that was conducted on behalf of the Belgian Science Policy and the Federal Public Service Employment, Labour and Social Dialogue in order to examine the possibilities to improve methods for measuring the extent of undeclared work in Belgium. The study revealed that eventually, a multitude of methods will have to be used. The bad image our country has because it accepts the most divergent estimates, can be turned into an advantage by taking the lead in conciliating and combining this multitude of methods. [less ▲]
