Abstract:
We have used longitudinal test data on various aspects of people's cognitive abilities to analyse whether overeducated workers are more vulnerable to a decline in their cognitive abilities, and undereducated workers are less vulnerable. We found that a job-worker mismatch induces a cognitive decline with respect to immediate and delayed recall abilities, cognitive flexibility and verbal fluency. Our findings indicate that, to some extent, it is the adjustment of the ability level of the overeducated and undereducated workers that adjusts initial job-worker mismatch. This adds to the relevance of preventing overeducation, and shows that being employed in a challenging job contributes to workers cognitive resilience.

Abstract:
This paper assesses the impact of a dramatic reform of the Dutch pension system on mental health, savings behavior and retirement expectations of workers nearing retirement age. The reform means that public sector workers born on January 1, 1950 or later face a substantial reduction in their pension rights while workers born before this threshold date may still retire under the old, more generous rules. We employ a unique matched survey and administrative data set comprising male public sector workers born in 1949 and 1950 and find strong ex ante effects on mental health for workers who are affected by the reform. This effect increases as birth dates approach the threshold date. Furthermore, the effects differ in accordance with worker characteristics. Finally, we find that the response of those affected by the reform is to work longer and to save more.

Abstract:
Using a dataset of science and engineering graduates from 12 European countries, we analyse the determinants of labour migration after graduation. We find that not only wage gains are driving the migration decision, but also differences in labour market opportunities, past migration experience, and international student exchange are strong predictors of future migration. Contrary to our expectations, job characteristics such as the utilisation of skills in the job and involvement in innovation hardly affect the migration decision. When analysing country choice, countries such as the USA, Canada and Australia appear to attract migrants due their larger R&D intensity. Moreover, graduates with higher grades are more likely to migrate to these countries.

Abstract:
Several studies show that employees with firm-specific skills are more likely to be covered by employer-sponsored pension schemes than workers with general skills. Therefore it can be expected that workers with firm-specific skills retire earlier. This paper tests this prediction using US data from the National Longitudinal Survey of Older Men. We find that workers who participated in firm-specific training in their early careers retire earlier than workers with a general training background. This indicates that shared investments in firm-specific training are embedded in implicit contracts that induce early retirement. The results remain robust when controlling for technological change and work commitment.

Abstract:
This paper uses a natural experiment approach to identify the effects of an exogenous change in future pension benefits on workers' training participation. We use unique matched survey and administrative data for male employees in the Dutch public sector who were born in 1949 or 1950. Only the latter were subject to a major pension reform that diminished their pension rights. We find that this exogenous shock to pension rights postpones expected retirement and increases participation in training courses among older employees, although exclusively for those employed in large organizations.

Abstract:
In this paper, we analyse the relationship between workers' competencies and their job satisfaction in the context of dual (i.e. vocational versus communicative) skill demands. We analyse the effects of workers' competencies on their overall, intrinsic, and extrinsic job satisfaction. We focus on pharmacy assistants who need both pharmaceutical and communicative competencies in their work. Results from a linked employer–employee survey show that assistants with more communicative competencies are more satisfied with their job, whereas assistants with more pharmaceutical competencies are not more satisfied than the less competent assistants. In addition, workers who perform tasks below their level of competence are more dissatisfied with both their remuneration and career prospects and the content of their job as such, than were other workers. Our results indicate that the demand shift from vocational towards communication skills, which occurs in many professions, can affect the job satisfaction of the most competent workers.

Abstract:
We analyse whether lower investments in human capital of part-time workers are due to workers' characteristics or human resource practices of the firm. We focus on investments in both formal training and informal learning. Using the Dutch Life-Long-Learning Survey 2007, we find that part-time workers have different determinants for formal training and informal learning from full-time workers. The latter benefit from firms' human resource practices such as performance interviews, personal development plans, and feedback. Part-time workers can only partly compensate the lack of firm support when they have a high learning motivation and imagination of their future development.

Abstract:
We estimate human capital depreciation rates during career interruptions due to family reasons (parental leave and household time) in male- and female-dominated occupations. If human capital depreciation due to family related career breaks is lower in female than in male occupations, this can explain occupational sex segregation because women will take the costs of future breaks into account when optimizing their lifetime earnings. We find that short-run depreciation rates in high-skilled occupations are significantly lower in female than in male occupations. In low-skilled occupations, there is no evidence of this difference. Our findings support the self-selection hypothesis with respect to occupational sex segregation in the more skilled jobs, i.e. high-skilled women might deliberately choose female occupations because of the lower short-term wage penalties for family-related career interruptions.

Abstract:
This paper, instrumented with six theorems, shows that differences between firms in labor productivity, capital intensity and relative demand for skilled labor can be explained by differences in the substitution parameters between capital, skilled and unskilled labor in the presence of skill biased technical change.

Abstract:
The analysis focuses on the extent to which the production function of firms exhibits systematical differences regarding the employment size. We evaluate the extent to which differences in the elasticities of substitution between skill-groups are of the magnitude to explain the firm-size effect on labour productivity. Elasticities of substitution are estimated using matched employer-employee data for Denmark (1992-1994). Empirical results show that large firms have higher elasticity of substitution between skilled workers in skilled-jobs and capital than smaller firms. The elasticity of substitution between skilled and unskilled workers in skilled jobs is larger in large firms. These differences are of the magnitude to explain the higher labour productivity and skill intensity observed in large firms.
