We examine in this paper the evolution of gender gaps in labor market outcomes during structural adjustment and explore the extent to which widening gaps can be attributed to women’s more limited geographical mobility. Using comparable household surveys carried out in 1988 and 1998we show that gender gaps in access to wage and salary employment and in(More)
We present a combined, consistent microsimulation-AGE model that uses the labour market model PACE-L, data from the German Socio-Economic Panel and a discrete choice labour supply estimation. The model is used to analyse reform proposals designed to encourage labour force participation at the lower end of the wage distribution. We compare the fully(More)
Recent labor market reforms in Germany aim, among other things, at reducing unemployment by restricting passive unemployment measures, emphasizing local labor market policies and re-structuring public employment services. This paper uses extensive individual administrative and regional aggregate data to explore the extent to which these factors are likely(More)
A physical model was derived for the synthesis of the antibiotic cephalexin with an industrial immobilized penicillin G acylase, called Assemblase. In reactions catalyzed by Assemblase, less product and more by-product are formed in comparison with a free-enzyme catalyzed reaction. The model incorporates reaction with a heterogeneous enzyme distribution,(More)
This paper evaluates the effects of a professionally assisted consumer-directed program (Personal Budgets) compared to the standard home care programs of the German long-term care insurance. The evaluation makes use of a long-run social experiment at seven different sites with a random assignment into a treatment group receiving personal budgets and a(More)
This paper examines the determinants of gross labour flows in a context where modeling the migration decision as a wage-maximizing process may be inadequate due to regional wage rigidities that result from central wage bargaining. In such a context, the framework that has been developed by Borjas et al. (1992) on the selectivity of internal migrants with(More)
This paper contributes to the sparse literature on employment spillovers on minimum wages by exploiting the minimum wage introduction and subsequent increases in the German roofing sector that gave rise to an internationally unprecedented hard bite of a minimum wage. We look at the chances of remaining employed in the roofing sector for workers with and(More)
A number of contributions have found evidence for motherhood being a critical life event for women’s employment careers. This study presents a detailed model for the duration of maternity leave in which young mothers can make a transition into a number of states related to employment and unemployment among others. The model incorporates a large number of(More)
This paper evaluates the incidence and extent of support as well as the remuneration of formal and informal caregivers for recipients of a professionally assisted consumer-directed program, a personal budget, compared to recipients of standard types of home care benefits of the German long-term care insurance, i.e. agency services and cash payments. The(More)
In a long-run social experiment, personal budgets have been tested as an alternative to the home care programs of the German long-term care insurance (LTCI). Due to extending the coverage beyond LTCI approved services and agencies, personal budgets may improve care outcomes compared to the provision of agency care at a constant benefit level, a highly(More)
