IWH Discussion Papers,
No. 21,
2009
Abstract
The aim of this paper is to analyze whether the formally equal qualifications acquired during a subsidized vocational education induce equal employment opportunities compared to regular vocational training. Using replacement matching on the basis of a statistical distance function, we are able to control for selection effects resulting from different personal and profession-related characteristics, and thus, to identify an unbiased effect of the public support. Besides the ‘total effect’ of support, it is of special interest if the effect is stronger for subsidized youths in external training compared to persons in workplace-related training. The analysis is based on unique and very detailed data, the Youth Panel of the Halle Centre for Social Research (zsh).
The results show that young people who successfully completed a subsidized vocational education are disadvantaged regarding their employment opportunities even when controlling for personal and profession-related influences on the employment prospects. Besides a quantitative effect, the analysis shows that the graduates of subsidized training work in slightly worse (underqualified) and worse paid jobs than the adolescents in the reference group. The comparison of both types of subsidized vocational training, however, does not confirm the expected stronger effect for youths in external vocational education compared to workplace-related training.

Is there a Superior Distance Function for Matching in Small Samples?
Eva Dettmann, Claudia Becker, Christian Schmeißer
Abstract
The study contributes to the development of ’standards’ for the application of matching algorithms in empirical evaluation studies. The focus is on the first step of the matching procedure, the choice of an appropriate distance function. Supplementary o most former studies, the simulation is strongly based on empirical evaluation ituations. This reality orientation induces the focus on small samples. Furthermore, ariables with different scale levels must be considered explicitly in the matching rocess. The choice of the analysed distance functions is determined by the results of former theoretical studies and recommendations in the empirical literature. Thus, in the simulation, 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-parametrical 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.

Determinanten ausländischer FuE-Aktivität in Deutschland und der EU27

Abstract
Obwohl es sich grundsätzlich um kein neues Phänomenhandelt, so hat in den letzten beiden Jahrzehnten die Internationalisierung von Forschungund Entwicklung (FuE) deutlich zugenommen. So zeigen z. B. Untersuchungen der OECD, dass die FuE-Ausgaben ausländischer Tochterunternehmen in der Periode zwischen 1995 und2003 doppelt so schnell angestiegen sind wie ihr Umsatz oder die aggregierten Importe des Gastlandes. Dies deutet darauf hin, dass FuE zu den dynamischen Elementen der Globalisierung gehört. Allerdings steht der Grad der FuE-Internationalisierung dem der Produktion oft noch nach, wenn man zumindest unterschiedliche Bereiche des Verarbeitenden Gewerbes in EU und OECD-Ländern betrachtet.

Determinants of Foreign Technological Activity in German Regions – A Count Model Analysis of Transnational Patents

Foresight-Russia,
No. 1,
2014
Abstract
Most research on R&D internationalisation focuses on comparative analysis of location factors at the national level of analysis. Very little work, however, has taken place in this field for the sub-national regional location behavior of multi-national enterprises (MNE). The paper contributes to the existing research by providing evidence on the determinants of foreign technological activities at the sub-national level for Germany, which hosts the largest share of foreign R&D within the EU27 and features the highest cross-regional dispersion of patented research. Using a pooled count data model, we estimate the effect of various sources for externalities on the extent of foreign technological activity across regions. Particular attention is paid to the role of local knowledge spillovers, technological specialization and diversification. We differentiate foreign and domestic sources of specialisation and account for region and sector-specific influences. This is the first time that the ‘cross-border-ownership’ principle to measure R&D internationalisation is combined with regionalised patent information.
To verify our findings we develop hypotheses. In particular, we expect and find that foreign technological activity is attracted by technologically specialised sectors of regions. In contrast to current empirical work, this effect applies both to foreign as well as domestic sources of specialization, although effects on foreign specialization seem more significant. We expect and find the same for science-industry spillovers. We postulate a negative impact of domestic specialization on foreign technological activities and a strong positive effect from diversificationspillovers, by comparison with specialisation spillovers, but these hypotheses are rejected. We find that the direction of the specialisation effect depends on dominance in the position of domestic firms as well as on the balance of knowledge flows between them and foreign actors.

flexpaneldid: A Stata Command for Causal Analysis with Varying Treatment Time and Duration
Eva Dettmann, Alexander Giebler, Antje Weyh
Abstract
>>A completely revised version of this paper has been published as: Dettmann, Eva; Giebler, Alexander; Weyh, Antje: flexpaneldid. A Stata Toolbox for Causal Analysis with Varying Treatment Time and Duration. IWH Discussion Paper 3/2020. Halle (Saale) 2020.<<
The paper presents a modification of the matching and difference-in-differences approach of Heckman et al. (1998) and its Stata implementation, the command flexpaneldid. The approach is particularly useful for causal analysis of treatments with varying start dates and varying treatment durations (like investment grants or other subsidy schemes). Introducing more flexibility enables the user to consider individual treatment and outcome periods for the treated observations. The flexpaneldid command for panel data implements the developed flexible difference-in-differences approach and commonly used alternatives like CEM Matching and difference-in-differences models. The novelty of this tool is an extensive data preprocessing to include time information into the matching approach and the treatment effect estimation. The core of the paper gives two comprehensive examples to explain the use of flexpaneldid and its options on the basis of a publicly accessible data set.

No. 12,
2009
Abstract
The aim of the study is to analyse whether the formally equal qualifications acquired during a subsidized vocational education induce equal employment opportunities compared to regular vocational training. This question is answered for adolescents in workplace-related training. Using replacement matching on the basis of a statistical distance function, we are able to control for selection effects resulting from different personal and profession-related characteristics and thus to identify an unbiased effect of the public support. The analysis is based on unique, very detailed data, the Youth Panel of the Halle Centre for Social Research (zsh).
The results show that young people who successfully completed a workplace-related training are disadvantaged regarding their employment opportunities even when controlling for personal and profession-related influences. Besides a quantitative effect on the percentage of employed adolescents, the analysis shows differences in the job quality: The employed graduates of workplace-related training work in worse paid jobs, and less are employed in qualification adequate occupations compared to matchable graduates of regular vocational education.

The Requirement of Qualified Workers in Thuringia until 2015: Forecast and Policy Recommendations
Herbert S. Buscher, Eva Dettmann, Christian Schmeißer, Marco Sunder, Dirk Trocka
Wirtschaft im Wandel,
No. 7,
2009
Abstract
We forecast the number of qualified workers required in the German federal state Thuringia until 2015 on the basis of the manpower requirement approach. Disaggregated by types of qualification, this method distinguishes between two sources of recruitment requirements: replacement demand for old workers and expansion demand to reflect structural changes of industry sectors and productivity growth. Both components are calculated from register data on employment covered by social security. Relative to current employment, recruitment requirements vary across occupations. A comparison of recruitment requirements for medium-skilled workers with the structure of vocational training reveals potential mismatch between demand and supply of medium-skilled labor in the near future if the composition of apprenticeship programs remains unchanged. The study closes with policy recommendations to prevent occupational mismatch.

Will There Be a Shortage of Skilled Labor? An East German Perspective to 2015
Herbert S. Buscher, Eva Dettmann, Marco Sunder, Dirk Trocka
IWH Discussion Papers,
No. 13,
2009
Abstract
We analyze the supply and demand of skilled labor in an East German federal state, Thuringia. This state has been facing high unemployment in the course of economic transformation and experiences population ageing and shrinking more rapidly than most West European regions. In a first step, we use extrapolation techniques to forecast labor supply and demand for the period 2009-2015, disaggregated by type of qualification. The analysis does not corroborate the notion of an imminent skilled-labor shortage but provides hints for a tightening labor market for skilled workers. In the second step, we ask firms about their appraisal of future recruitment conditions, and both current and planned strategies in the context of personnel management. The majority of firms plan to expand further education efforts and hire older workers. The study closes with policy recommendations to prevent occupational mismatch.
