Firm-specific training: Consequences for job mobility

This paper analyzes the impact of formal training on worker mobility. Using data from the Swiss Labor Force Survey, we find that on-the-job search activities and, to a smaller extent, actual job separations are significantly affected by both employer-provided and general training. Moreover, while the separation probability of searching workers is strongly affected by previous firm-provided training, no such effect shows up for non-searchers. This is consistent with the hypothesis that workers bear most of the cost of specific training.firm-specific training; on-the-job-search; turnover.

Smoking, discount rates, and returns to education

Individual time preference determines schooling enrolment. Moreover, smoking behavior in early ages has been shown to be highly related to time preference rates. Accordingly, we use smoking at age 16 as an instrument for schooling in order to cope with ability bias in a returns to education regression. Doing this for Austrian cross-sectional data, we find no evidence of ability bias.returns to education, instrumental variables, ability bias, discount rates

Returns to Apprenticeship Training in Austria: Evidence from Failed Firms

Little is known about the payoffs to apprenticeship training in the German speaking countries for the participants. OLS estimates suggest that the returns are similar to those of other types of schooling. However, there is a lot of heterogeneity in the types of apprenticeships offered, and institutional descriptions suggest that there might be an important element of selection in who obtains an apprenticeship, and what type. In order to overcome the resulting ability bias we estimate returns to apprenticeship training for apprentices in failed firms in Austria. When a firm fails, current apprentices cannot complete their training in this firm. Because apprentices will be at different stages in their apprenticeship at that time, the failure of a firm will manipulate the length of the apprenticeship period completed for some apprentices. The time to the firm failure therefore serves as an instrument for the length of the apprenticeship completed both at the original firm and at other firms. We find instrumental variables returns which are similar or larger than the OLS returns in our sample, indicating relatively little selection.

Too Old to Work, Too Young to Retire?

We use firm closure data from social security records for Austria 1978-1998 to investigate the effect of age on employment prospects. We rely on exact matching to compare workers displaced due to firm closure with similar non-displaced workers. We then use a difference-in- difference strategy to analyze employment and earnings of older relative to prime-age workers in the displacement and non-displacement groups. Results suggest that immediately after plant closure the old have lower re-employment probabilities as compared to prime-age workers but later they catch up. While among the young the employment prospects of the displaced remain persistently different from those of the non-displaced, among the old the effect of displacement fades away, and actually disappears even immediately after plant closure when the effect of tenure based severance payment is controlled for. Our evidence suggests that increasing the retirement age does not necessarily produce individuals who are “too old to work but too young to retire”.Aging; Employability; Plant Closures; Matching

Numerical simulation of growth of Escherichia coli in unsaturated porous media

A model for the aerobic and anaerobic growth of Escherichia coli (HB101 K12 pGLO) depending on the concentration of oxygen and DOC as substrate has been developed based on laboratory batch experiments. Using inverse modelling to obtain optimal sets of parameters, it could be shown that a model based on a modified double Contois kinetic can predict cell densities, organic carbon utilisation, oxygen transfer and utilisation rates for a large number of experiments under aerobic and anaerobic conditions with a single unique set of parameters. The model was extended to describe growth of E. coli in unsaturated porous media, combining diffusion, phase exchange and microbiological growth. Experiments in a Hele-Shaw cell, filled with quartz sand, were conducted to study bacterial growth in the capillary fringe above a saturated porous medium. Cell density profiles in the Hele-Shaw cell were predicted with the growth model and the parameters from the batch experiments without any further calibration. They showed a very good qualitative and quantitative agreement with cell densities determined from samples taken from the Hele-Shaw cell by re-suspension and subsequent counting. Thus it could be shown, that it is possible to successfully transfer growth parameters from batch experiments to porous media for both aerobic and anaerobic conditions.Comment: Minor changes in conclusions, results unchange

Does the color of the collar matter? Firm specific human capital and post-displacement outcomes

We investigate whether the costs of job displacement differ between blue collar and white collar workers. In the short run earnings and employment losses are substantial for both groups but stronger for white collar workes. In the long run, there are only weak effects for blue collar workers but strong and persistent effects for white collars. This is consistent with the idea that firm-specific human capital and internal labor markets are more important in white-collar than in blue collar jobs.Firm Specific Human Capital, Plant Closures, Matching

Job creation and job destruction in a regulated labor market: The case of Austria

We study Austrian job reallocation in the period of 1978 to 1998, using a large administrative dataset where we correct for "spurious" entries and exits of firms. We find that on average 9 out of 100 randomly selected jobs were created within the last year, and that about 9 out of randomly selected 100 jobs will be destroyed within the next year. Hence, Austrian job flows seem to be of comparable magnitude as in other countries, similar to the well-known results of Davis et al. (1996) for the United States. Job reallocation appears to be driven primarily by idiosyncratic shocks. However, job creation increases significantly during cyclical upswings whereas job destruction rises in downturns. We also find substantial persistence of job creation and destruction. We show that the pronounced pattern of job reallocation rates falling with firm size and age continues to hold when we use a set of controls. Finally, we show that - controlling for sector and for firm size composition - Austrian job reallocation rates are only half the rates for the U. S. This result is not surprising given the impact of tighter regulation and labor law in Austria.Labor reallocation; job flows; labor market regulation
