Abstract
The poor performance often attributed to many public employment services may be explained in part by a delegation problem between the central office and local job centers. In markets characterized by frictions, job centers function as match-makers, linking job seekers with relevant vacancies. Because their search intensity in contacting employers and collecting data is not verifiable by the central authority, a typical moral hazard problem can arise. To overcome the delegation problem and provide high-powered incentives for high levels of search effort on the part of job centers, we propose output-related schemes that assign greater staff capacity to agencies achieving high strike rates.

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.

Subsidized Vocational Training: Stepping Stone or Trap? An Evaluation Study for East Germany
Eva Dettmann, Jutta Günther
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.

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.

Professor Qualities and Student Achievement
Florian Hoffmann, Philip Oreopoulos
Review of Economics and Statistics,
No. 1,
2009
Abstract
This paper analyzes the importance of teacher quality at the college level. Instructors are matched to objective and subjective characteristics of teacher quality to estimate the impact of rank, salary, and perceived effectiveness on student performance and subject interest. Student and course fixed effects, time of day and week controls, and students' lack of knowledge about first-year instructors help minimize selection biases. Subjective teacher evaluations perform well in measuring instructor influences on students, while objective characteristics such as rank and salary do not. Overall, the importance of college instructor differences is small, but important outliers exist.

Demographic Change and Labour Markets: Why are Older Employees less Mobile?
Lutz Schneider
Wirtschaft im Wandel,
No. 10,
2008
Abstract
Since older workers are less disposed to change jobs workforce ageing will affect labour mobility in Germany. On the basis of the IAB-Employment Sample (IABS) the contribution analyzes the effect of age on job and occupational mobility. The study focuses on the question whether older workers are less mobile due to the optimal matching quality of their current job which cannot be improved by job switches or whether other factors have to be considered for explaining the age related mobility decline.
Econometric results firstly confirm the significance of expected wage growth for mobility decision across all age groups. Secondly, older workers seem to benefit from wage increase due to a job change less frequently than younger workers. However, this factor explains only a part of the mobility lag. Even after controlling for the wage effect younger workers change jobs more often than older ones.
For this reason the opinion that ageing will impede the labour market adjustments cannot be disabled. If older workers only slightly react on wage signals and do not respond to attractive offers growing firms might face problems to recruit appropriate staff – a trend which could have negative consequences for technological and sectoral changes of the entire economy.

Comparing the training activities of unemployed and full-time employed people
Birgit Schultz, Joachim Wilde
Zeitschrift für Arbeitsmarktforschung,
No. 1,
2008
Abstract
Many empirical studies for Germany consider either the training activities of the unemployed or those of employees. However, a comprehensive comparison of both groups had not been conducted until now. The paper closes this gap. Using data from the latest time-use survey (Zeitbudgeterhebung) of the Federal Statistical Office, the amount of training undertaken by the two groups is compared. Furthermore, the types of activities that are made use of in particular are described. Heterogeneity due to different relevant socioeconomic characteristics in the two groups is eliminated by applying a matching procedure. The findings demonstrate that only 49% of unemployed people participate in any kind of training activity off the job. In the case of full-time employment 59 % would take part. Concerning the average expenditure of time per week the difference is reversed, i.e. the expenditure of time is greater during unemployment. However, a large proportion of the training activities undertaken by the unemployed comprises general training, e.g. by reading books or watching television. Furthermore, the result is driven by a different potential of time that can be used for training activities off the job. In relation to this potential of time, the amount of training activity is still smaller during unemployment.

Abstract
Many empirical studies consider either training activities of the unemployed or training activities of the employees in Germany. However, a comprehensive comparison of both groups is missing. The paper closes this gap. Using data of the latest time use survey (Zeitbudgeterhebung) of the Federal Statistical Office, the amount of training is compared for both groups. Furthermore, it is described which types of activities are made use of in particular. Heterogeneity due to different relevant socioeconomic characteristics in the two groups is eliminated by the appliance of a matching procedure. Findings demonstrate that only 49% of the unemployed persons participate in any kind of training activities off the job. In case of the full-time employment 59 % would take part. Concerning the average expenditure of time per week the difference turns around, i.e. the expenditure of time is higher during unemployment. However, a high proportion of the training activities of the unemployed falls upon general training, e.g. by reading books or watching TV. Furthermore, the result is driven by a different potential of time that can be used for training activities off the job. Relating to this potential of time the amount of training activities is still lower during unemployment.
