Is There a Gap in the Gap? Regional Differences in the Gender Pay Gap
Scottish Journal of Political Economy,
In this paper, we investigate regional differences in the gender pay gap both theoretically and empirically. Within a spatial model of monopsonistic competition, we show that more densely populated labour markets are more competitive and constrain employers’ ability to discriminate against women. Utilizing a large administrative data set for western Germany and a flexible semi-parametric propensity score matching approach, we find that the unexplained gender pay gap for young workers is substantially lower in large metropolitan than in rural areas. This regional gap in the gap of roughly 10 percentage points remained surprisingly constant over the entire observation period of 30 years.
Distance Functions for Matching in Small Samples
Computational Statistics & Data Analysis,
The development of ‘standards’ for the application of matching algorithms in empirical evaluation studies is still an outstanding goal. The first step of the matching procedure is the choice of an appropriate distance function. In empirical evaluation situations often the sample sizes are small. Moreover, they consist of variables with different scale levels which have to be considered explicitly in the matching process. A simulation is performed which is directed towards these empirical challenges and supplements former studies in this respect. The choice of the analysed distance functions is determined by the results of former theoretical studies and recommendations in the empirical literature. Thus, two balancing scores (the propensity score and the index score) and the Mahalanobis distance are considered. Additionally, aggregated statistical distance functions not yet used for empirical evaluation are included. The matching outcomes are compared using non-parametric scale-specific tests for identical distributions of the characteristics in the treatment and the control groups. The simulation results show that, in small samples, aggregated statistical distance functions are the better choice for summarising similarities in differently scaled variables compared to the commonly used measures.
Efficiency of qualification and job creating measures in East Germany
Wirtschaft im Wandel,
This paper evaluates job creation schemes and further training in East Germany for the period 1990-1998. We identify the causal effect of the treatment-on-the-treated by a two-step procedure: First, we apply the matching technique based on estimated propensity scores. Secondly, we use the Difference-in-Differences estimator. Hereby, we take especially consideration on Ashenfelter s Dip, which characterize a significant decrease in the participants employment shortly before the start of a program. This can be assumed to be related to the anticipation of the participation.
