This study analyses the treatment effects of public training programmes for the unemployed in Germany. Based on propensity score matching methods, we extend the picture that has been sketched in previous studies by estimating the treatment effects of medium-term programmes for different skill and age groups. Our results indicate that programme participation has a positive impact on employment probabilities and earnings for almost all sub-groups. We find little evidence for the presence of heterogeneous treatment effects, and the magnitude of the differences is quite small. Our results thus - at least in part - conflict with the strategy to provide training increasingly to individuals with better employment prospects.

Abstract-For many years, researchers have presented the geocoding of postal addresses as a challenge. Several research works have been devoted to achieve the geocoding process. This paper presents theoretical and technical aspects for geolocalization, geocoding, and record linkage. It shows possibilities and limitations of existing methods and commercial software identifying areas for further research. In particular, we present a methodology and a computing tool allowing the correction and the geo-coding of mailing addresses. The paper presents two main steps of the methodology. The first preliminary step is addresses correction (addresses matching), while the second caries geocoding of identified addresses. Additionally, we present some results from the processing of real data sets. Finally, in the discussion, areas for further research are identified.
