IWH Discussion Papers,
No. 7,
2008
Abstract
In Germany, a growing tendency can be observed to focus business incubators (BIs) and technology centers and their respective support elements and processes as well as the selection criteria applied by the incubator management on firms from solely one sector or few but complementary sectors and their specific needs and requirements. These are called specialized business incubators (SBIs). Despite the increasing importance of specialization strategies of business incubators as local and regional policy instruments, there are no reliable empirical examinations of the specifics, and advantages in particular, of SBIs compared to more diversified BIs. On the basis of survey-data, that comprises responses from 161 actual firms incubated in 13 diversified BIs and 13 specialized BIs in Germany, this study investigates the mechanisms within the specific context of specialized BIs and their value-added contribution versus the more diversified incubation model. For the first time, this study provides large-scale empirical evidence concerning the effects of adopting a specialization strategy in the context of business incubation.

Does temporary employment influence the workrelated training of low-skilled employees?
Eva Reinowski, Jan Sauermann
IWH Discussion Papers,
No. 2,
2008
Abstract
Fixed-term contracts are considerd as one of the most popular instruments of labour market flexibility. Although they provide new labour market options for employer and employees, it is argued that they may lead to decreasing investments in human capital. From the theoretical point of view it is not clear wheter a fixed-term contract is a drawback for the participation in work-related training. The paper deals with the influence of fixed-term contracts on work-related training especially for low-skilled workers. Based on the Micro Census data of 2004, we estimate a bivariate probit model for the probability of fixed-term employment and participating in work-related training. This model enables us to control for selection effects that may arise from unobservable factors. From the estimation results we can conclude that holding a fixed-term contract does not mean a systematical disadvantage for the training probability of low-skilled employees.

Analysis of location of large-area shopping centres - A probalistic gravity model for the Halle-Leipzig area
Alexander Kubis, Maria Hartmann
Jahrbuch für Regionalwissenschaft,
No. 1,
2007
Abstract
A profund analysis of large-area shopping centres from the perspective of retail, but also of communes is of importance for the choice of site selection. In central Germany, the Halle–Leipzig area represents an example of strong competitiveness between the different participants in retail. The analysis described in this article is based on the MCI Model of Nakanishi and Cooper, which is used to investigate the regional influences of nine large shopping centres in the area of interest. The analysis demonstrates, that the studied shopping centres intensely affect the structure of retail in the region and exert a strong influence on the structural weakness of the surrounding cities due to their relative success in comparison to other retail locations city centres. An important volume of the turnover of the administrative districts flows to the analysed shopping centres. On the other hand, the article describes the influence of a systematic location decision on the reachable turnover potential of the modelized large-area shopping centres among each other. The shopping centres Saale Park (today Nova Eventis) near Leipzig and the Paunsdorf Center in Leipzig show the biggest influence on the competing centres.

Who Invests in Training if Contracts are Temporary? - Empirical Evidence for Germany Using Selection Correction
Jan Sauermann
IWH Discussion Papers,
No. 14,
2006
Abstract
This study deals with the effect of fixed-term contracts on work-related training. Though previous studies found a negative effect of fixed-term contracts on the participation in training, from the theoretical point of view it is not clear whether workers with fixed-term contracts receive less or more training, compared to workers with permanent contracts. In addition to the existing strand of literature, we especially distinguish between employer- and employee-financed training in order to allow for diverging investment patterns of worker and firm. Using data from the German Socio-Economic Panel (GSOEP), we estimate a bivariate probit model to control for selection effects that may arise from unobservable factors, affecting both participation in training and holding fixed-term contracts. Finding negative effects for employer-sponsored, as well as for employee-sponsored training, leads us to conclude that workers with fixed-term contracts do not compensate for lower firm investments.

Promotion of investment in East Germany - Results of an empirical study of effectiveness
Harald Lehmann, Andreas Stierwald
Wirtschaft im Wandel,
No. 5,
2004
Abstract
In Germany considerable amounts of public funds are being spent on business development programs. In order to do so economic reasoning is needed. In particular the programs for supporting investment lack microeconometric empirical evaluation. To close this gap the special program „Gemeinschaftsaufgabe zur Verbesserung der regionalen Wirtschaftsstruktur“ (GA) is exemplarily analyzed. This program is intended to strengthen the capital stock of the East German economy, so firms of the East German manufacturing industries will be studied. A comparison of the two fundamental methods for microeconometric evaluation shall demonstrate the general problems in analyzing the effectiveness of development programs. The matching estimator provides more stable results then a sample selectivity model. The results suggest that the GA generates considerable extra investment activities.

Softening Competition by Inducing Switching in Credit Markets
Jan Bouckaert, Hans Degryse
Journal of Industrial Economics,
No. 1,
2004
Abstract
We show that competing banks relax overall competition by inducing borrowers to switch lenders. We illustrate our findings in a two-period model with adverse selection where banks strategically commit to disclosing borrower information. By doing this, they invite rivals to poach their first-period market. Disclosure of borrower information increases the rival's second-period profits. This dampens competition for serving the first-period market.

Evolving Structural Patterns in the Enlarging European Division of Labour: Sectoral and Branch Specialisation and the Potentials for Closing the Productivity Gap
Johannes Stephan
IWH-Sonderhefte,
No. 5,
2003
Abstract
This report summarises the results generated in empirical analysis within a larger EU 5th FP RTD-project on the determinants of productivity gaps between the current EU-15 and accession states in Central East Europe. The focus of research in this part of the project is on sectoral specialisation patterns emerging as a result of intensifying integration between the current EU and a selection of six newly acceding economies, namely Estonia, Poland, the Czech and Slovak Republics, Hungary and Slovenia. The research-leading question is concerned with the role played by the respective specialisation patterns for (i) the explanation of observed productivity gaps and for (ii) the projection of future potentials of productivity growth in Central East Europe.
For the aggregated level, analysis determines the share of national productivity gaps accountable to acceding countries’ particular sectoral patterns, and their role for aggregate productivity growth: in Poland, the Slovak Republic and Hungary, sectoral shares of national productivity gaps are considerable and might evolve into a ‘barrier’ to productivity catch-up.Moreover, past productivity growth was dominated by a downward adjustment in employment rather than structural change. With the industrial sector of manufacturing having been identified as the main source of national productivity gaps and growth, the subsequent analysis focuses on the role of industrial specialisation patterns and develops an empirical model to project future productivity growth potentials. Each chapter closes with some policy conclusions.

Evaluation von Maßnahmen der aktiven Arbeitsmarktpolitik mit Hilfe eines iterativen Matching-Algorithmus - Eine Fallstudie über langzeitarbeitslose Maßnahmeteilnehmer in Sachsen
Eva Reinowski, Birgit Schultz, Jürgen Wiemers
IWH Discussion Papers,
No. 173,
2003
Abstract
The paper evaluates the effects of two labor market programs in Germany, namely the Job Creation- /Structural Adjustment Scheme and Vocational Training, on the unemployment duration of long term unemployed persons. The study uses data from the Mikrozensus Sachsen. A two step Nearest-Neighbor-Matching is employed to solve the sample selection problem. The first step is the estimation of the participation tendency to obtain potential pairs and to compute their Mahalanobis distances. For the assignment of pairs in the second step two different procedures are used: a standard technique and a new one - the iterative improvement of an initial assignment. This process is superior to the standard matching algorithms in the sense that it allows for a closer match between participants and non-participants. Including additional information about a person’s employment history enables us to eliminate the bias due to unobservables. The impact of participation in a labor market program is evaluated by comparing the unemployment duration between both groups using the Cox Proportional Hazard Model. Overall we find empirical evidence that both participation in Job Creation- /Structural Adjustment Scheme and Vocational Training result in even longer unemployment.
