Wage Penalties for Career Interruptions: An Empirical Analysis for West Germany

This paper examines the wage effects of different types of career interruptions. We consider the timing and duration of non-employment spells by exploiting an administrative data set of German social security accounts (IAB employment sample) supplemented with information on the employees? entire working lives (IAB supplement sample I). These data allow us to distinguish between employment breaks due to registered unemployment, formal parental leave, training or other reasons – a distinction which can only be approximated using just the IAB employment sample. Our IV fixed effects estimation results suggest that women?s labor supply is endogenously determined, whereas men?s employment histories can be treated as exogenous. Career interruptions reduce the wage rates of both men and women. Moreover, the wage cuts resulting from unemployment, parental leave and additional home time are larger than the pure human capital effects of missing experience, hinting at a possible stigmatization of workers with discontinuous employment histories. --career interruptions,returns to experience,wage differentials,panel estimation

Does Work Time Flexibility Work? An Empirical Assessment of the Efficiency Effects for German Firms

In this paper we assess the impact of flexible work time schedules on firm efficiency using representative establishment data for Germany. Following the approach by Battese and Coelli (1995), we estimate a stochastic production frontier and the determinants of technical efficiency simultaneously. The innovation of our study is that we draw on technical efficiency instead of productivity to appraise the success of flexible working hours. The results indicate that while the use of work time schedules with moderate flexibility is positively related to technical efficiency, highly flexible work time arrangements seem to be negatively correlated with an efficient organization of the work flow. However, these efficiency losses should not be interpreted as causal effects, because highly flexible work time schedules are most likely to be introduced in struggling firms. --Stochastic production frontier,flexible work hours,efficiency

How much does a year off cost? Estimating the wage effects of employment breaks and part-time periods

Discontinuities in the employment profile are supposed to cause wage cuts since they imply an interruption in the accumulation of human capital as well as a depreciation of the human capital stock built up in the past. In this paper, we estimate the return to effective experience, taking into account both the timing and the duration of non-work and part-time employment spells. Estimation results for German women suggest that deviations from full-time employment are associated with significant wage cuts owing to the depreciation of human capital. Postponing the discontinuity leads to a further fall of the wage rate. Controlling for individual heterogeneity with respect to industry sector and job position decreases the estimated depreciation rates. This we interpret as an indication for segregation in the labor market. We conclude that traditional wage estimations that do not control for depreciation underestimate the return to effective experience. --

The wage effects of entering motherhood: a within-firm matching approach

We analyze the wage effects of employment breaks of women entering motherhood using a novel within-firm matching approach where mothers? wages upon return to the job are compared with those of their female colleagues within the same firm. Using an administrative German data set we investigate three different matching procedures based on information two years before birth: (1) exact matching on individual characteristics, (2) propensity score matching and (3) a combined procedure of exact and propensity score matching. Our results yield new insights into the nature of the wage penalty associated with motherhood, since we find first births to reduce women?s wages by 16 to 19 percent, regardless of the matching procedure applied. Neglecting the firm identifier and matching across all firms, however, yields a wage cut of 30 percent. Furthermore, we can show that the wage loss increases with the duration of the employment break. --wages,parental leave,matching

Is there a wage premium or wage discount for flexible hours?

With flexible work time arrangements firms can quickly adjust to demand fluctuations, while employees may benefit from more time sovereignty. Depending on the specific type of arrangement the accompanying wage effects are ambiguous and have rarely been analyzed. According to the theory of compensating wage differentials, workers with more time sovereignty may be willing to forego earnings whereas others need to be compensated by higher earnings. We analyze the wage effects of work time accounts using GSOEP data from 2002. We compare wages of employees with and without work time accounts by propensity score matching. Our results indicate that work time accountees receive higher wages on average, thus suggesting an employer's discretion to determine the timing of flexible work hours, but with remarkable differences across sectors. --work time flexibility, propensity score matching, compensating wage differentials
