    Does the estimation of the propensity score by machine learning improve matching estimation? The case of Germany’s programmes for long term unemployed

    12 February 2020

    Matching-type estimators using the propensity score are the major workhorse in active labour market policy evaluation. This work investigates if machine learning algorithms for estimating the propensity score lead to more credible estimation of average treatment effects on the treated using a radius matching framework.

    Firm Productivity, Wages, and Sorting

    05 February 2020

    Increasing wage inequality is associated with changes in the degree of labor market sorting,
    i.e. the allocation of workers to firms. To measure sorting, we propose a new method
    which disentangles the respective contributions of worker and firm heterogeneity to wage
    inequality. Inspired by sorting theory, we infer firm productivity from estimating firm-level
    production functions, taking into account that worker ability and firm productivity may interact
    at the match level.

    The Effect of Social Networks on Migrants' Labor Market Integration: A Natural Experiment

    20 January 2020

    Empirically identifying the causal effect of social networks on migrants’ economic prospects is a challenging task due to the non-random residential sorting of migrants into locations with greater opportunities for (previous) connections. Our study addresses this selection-bias issue by using a unique natural-experimental dataset of refugees and other migrants that were exogenously allocated to their first place of residence by German authorities. The empirical results reveal a positive causal effect of social networks on migrants’ transition rate to the first job, but only if the networks are mobilized for the job search.

    Career paths of PhD graduates in eastern and western Germany: Same qualification, same labor market Outcomes?

    15 January 2020

    This paper investigates the extent to which the returns to gaining a PhD degree depend upon the region of birth, the region where the degree was earned, and the place of work. Eastern Germany serves as an interesting showcase in light of the ongoing debate surrounding the underrepresen-tation of eastern Germans in top positions in Germany. We examine the career paths of eastern and western German PhD graduates who completed their dissertations between 1995 and 2010. We estimate the returns with regard to obtaining a job suited to their skill level and with high wages.

    Occupational routine-intensity and the costs of job loss: evidence from mass layoffs

    23 December 2019

    This paper analyses how differences in the degree of occupational routine-intensity affect the costs of job loss. We use worker-level data on mass layoffs in Germany between 1980 and 2010 and provide causal evidence that workers who used to be employed in more routine-intensive occupations suffer larger and more persistent earnings losses after the mass layoff. Furthermore, we are able to show that, at least initially, earnings losses are primarily due to a reduction in the number of days in employment, suggesting that routine-intensive workers face considerable frictions in the adjustment to job loss. Conditional on finding a new job, routine-intensive workers are more likely to change their occupations but end up systematically in the lower end of their new occupation’s wage distribution.
