Betriebsräte und andere Formen der betrieblichen Mitarbeitervertretung – Substitute oder Komplemente?

Stefan Ertelt, Boris Hirsch, Claus Schnabel
Industrielle Beziehungen, Nr. 3, 2017
Abstract
Der Beitrag untersucht anhand des IAB-Betriebspanels (2004-2013) die Verbreitung, Entwicklung und Interdependenz von Betriebsräten und anderen, meist betriebsinitiierten Formen der Mitarbeitervertretung (wie z.B. Runde Tische). In der Privatwirtschaft sind Betriebsräte gleich häufig zu finden wie andere Mitarbeitervertretungen, doch kommt eine gleichzeitige Existenz beider Gremien in einem Betrieb kaum vor. Ökonometrische Analysen mit rekursiven Probit-Modellen verdeutlichen, dass z.T. unterschiedliche Faktoren das Vorhandensein dieser alternativen Formen der Mitarbeitervertretung erklären und dass bezüglich ihrer Existenz, Gründung und Auflösung Betriebsräte und andere Mitarbeitervertretungen negativ miteinander korrelieren. Dies deutet darauf hin, dass zwischen beiden Formen der Arbeitnehmerpartizipation eine überwiegend substitutive Beziehung besteht.

Criminal Network Formation and Optimal Detection Policy: The Role of Cascade of Detection

Liuchun Deng, Yufeng Sun
Journal of Economic Behavior & Organization, September 2017
Abstract
This paper investigates the effect of cascade of detection, how detection of a criminal triggers detection of his network neighbors, on criminal network formation. We develop a model in which criminals choose both links and actions. We show that the degree of cascade of detection plays an important role in shaping equilibrium criminal networks. Surprisingly, greater cascade of detection could reduce ex ante social welfare. In particular, we prove that full cascade of detection yields a weakly denser criminal network than that under partial cascade of detection. We further characterize the optimal allocation of the detection resource and demonstrate that it should be highly asymmetric among ex ante identical agents.

Benchmark Value-added Chains and Regional Clusters in R&D-intensive Industries

Reinhold Kosfeld, Mirko Titze
International Regional Science Review, Nr. 5, 2017
Abstract
Although the phase of euphoria seems to be over, policy makers and regional agencies have maintained their interest in cluster policy. Modern cluster theory provides reasons for positive external effects that may accrue from interaction in a group of proximate enterprises operating in common and related fields. Although there has been some progress in locating clusters, in most cases only limited knowledge on the geographical extent of regional clusters has been established. In the present article, we present a hybrid approach to cluster identification. Dominant buyer–supplier relationships are derived by qualitative input–output analysis from national input–output tables, and potential regional clusters are identified by spatial scanning. This procedure is employed to identify clusters of German research and development-intensive industries. A sensitivity analysis reveals good robustness properties of the hybrid approach with respect to variations in the quantitative cluster composition.

Gender Quotas and Human Capital Formation: A Relative Deprivation Approach

Walter Hyll
German Economic Review, Nr. 3, 2017
Abstract
We study a quota's effect on individual human capital investment incentives beyond merely altering individual's overall probability of being promoted. We assume that individuals sense relative deprivation from unfavorable (income) comparisons within their reference group and that comparisons take place within the same gender. The introduction of a female quota increases (decreases) the number of women (men) holding top positions. On one hand, the relative deprivation to which female individuals are subjected to increases. These female individuals respond to an increase in their relative deprivation by acquiring additional human capital which, because it enables them to increase their earnings, reduces their relative deprivation. On the other hand, male individuals invest less in human capital in response to a decrease in relative deprivation. We show that the human capital formed by women who are encouraged to do so by the quotas is larger than the human capital that men who are discouraged by the quotas refrain from forming. However, the positive human capital accumulation effect hinges on a certain level of ability by gender and on how much individuals perceive relative deprivation.

Imputation Rules for the Implementation of the Pre-unification Education Variable in the BASiD Data Set

André Diegmann
Journal for Labour Market Research, 2017
Abstract
Using combined data from the German Pension Insurance and the Federal Employment Agency (BASiD), this study proposes different procedures for imputing the pre-unification education variable in the BASiD data. To do so, we exploit information on education-related periods that are creditable for the Pension Insurance. Combining these periods with information on the educational system in the former GDR, we propose three different imputation procedures, which we validate using external GDR census data for selected age groups. A common result from all procedures is that they tend to underpredict (overpredict) the share of high-skilled (low-skilled) for the oldest age groups. Comparing our imputed education variable with information on educational attainment from the Integrated Employment Biographies (IEB) reveals that the best match is obtained for the vocational training degree. Although regressions show that misclassification with respect to IEB information is clearly related to observables, we do not find any systematic pattern across skill groups.

When the Meaning of Work Has Disappeared: Experimental Evidence on Employees’ Performance and Emotions

Adrian Chadi, Sabrina Jeworrek, Vanessa Mertins
Management Science, Nr. 6, 2017
Abstract
This experiment tests for a causal relationship between the meaning of work and employees’ motivation to perform well. The study builds on an existing employer–employee relationship, adding realism to the ongoing research of task meaning. Owing to an unexpected project cancelation, we are able to study how varying the information provided about the meaning of previously conducted work — without the use of deception, but still maintaining a high level of control — affects subsequent performance. We observe a strong decline in exerted effort when we inform workers about the meaninglessness of a job already done. Our data also suggests that providing a supplemental alternative meaning perfectly compensates for this negative performance effect. Individual characteristics such as reciprocal inclinations and trust prompt different reactions. The data also show that the meaning of work affects workers’ emotions, but we cannot establish a clear relationship between emotional responses and performance.

The Dynamic Effects of Works Councils on Labour Productivity: First Evidence from Panel Data

Steffen Müller, Jens Stegmaier
British Journal of Industrial Relations, Nr. 2, 2017
Abstract
We estimate dynamic effects of works councils on labour productivity using newly available information from West German establishment panel data. Conditioning on plant fixed effects and control variables, we find negative productivity effects during the first five years after council introduction but a steady and substantial increase in the councils’ productivity effect thereafter. Our findings support a causal interpretation for the positive correlation between council existence and plant productivity that has been frequently reported in previous studies.

The Effects of Local Elections on National Military Spending: A Cross-country Study

Liuchun Deng, Yufeng Sun
Defence and Peace Economics, Nr. 3, 2017
Abstract
In this paper, we study the domestic political determinants of military spending. Our conceptual framework suggests that power distribution over local and central governments influences the government provision of national public goods, in our context, military expenditure. Drawing on a large cross-country panel, we demonstrate that having local elections will decrease a country’s military expenditure markedly, controlling for other political and economic variables. According to our preferred estimates, a country’s military expenditure is on average 20% lower if its state government officials are locally elected, which is consistent with our theoretical prediction.

Transferability of Skills across Sectors and Heterogeneous Displacement Costs

Moises Yi, Steffen Müller, Jens Stegmaier
American Economic Review: Papers and Proceedings, Nr. 5, 2017
Abstract
We use rich German administrative data to estimate new measures of skill transferability between manufacturing and other sectors. These measures capture the value of workers' human capital when applied in different sectors and are directly related to workers' displacement costs. We estimate these transferability measures using a selection correction model, which addresses workers' endogenous mobility, and a novel selection instrument based on the social network of workers. Our results indicate substantial heterogeneity in how workers can transfer their skills when they move across sectors, which implies heterogeneous displacement costs that depend on the sector to which workers reallocate.

Immigration and the Rise of American Ingenuity

Ufuk Akcigit, John Grigsby, Tom Nicholas
American Economic Review, Nr. 5, 2017
Abstract
We build on the analysis in Akcigit, Grigsby, and Nicholas (2017) by using US patent and census data to examine the relationship between immigration and innovation. We construct a measure of foreign born expertise and show that technology areas where immigrant inventors were prevalent between 1880 and 1940 experienced more patenting and citations between 1940 and 2000. The contribution of immigrant inventors to US innovation was substantial. We also show that immigrant inventors were more productive than native born inventors; however, they received significantly lower levels of labor income. The immigrant inventor wage-gap cannot be explained by differentials in productivity.
