Spatial Dependence and Heterogeneity in Empirical Analyses of Regional Labour Market Dynamics
23 June 2015
Empirical research in economics and social studies often treat regions within a country as independent islands. Moreover, they implicitly assume that effects or relations are homogenous across all regions. Both assumptions seem unrealistic: for example, the impact of a global shock is likely to vary from one region to another. In this issue on regional labour markets, Norbert Schanne employs novel methods in spatial econometrics to describe and forecast their development. The analysis particularly focusses on the heterogeneity of regional dynamics and the spatially structured interdependency between locations.
Wages in high-tech start-ups – do academic spin-offs pay a wage premium?
15 June 2015
Due to their origin from universities, academic spin-offs operate at the forefront of the technological development. Therefore, spin-offs exhibit a skill-biased labour demand, i.e. spin-offs have a high demand for employees with cutting edge knowledge and technical skills that distinguish them even from other high-tech start-up firms. In order to accommodate this demand, spin-offs may have to pay a relative wage premium compared to other high-tech start-ups. However, neither a comprehensive theoretical assessment nor the empirical literature on wages in start-ups unambiguously predicts the existence and the direction of wage differentials between spin-offs and non-spin-offs. This paper addresses this research gap and examines empirically whether or not spin-offs pay their employees a wage premium.

The role of innovation and agglomeration for employment growth in the environmental sector
01 June 2015
The environmental sector is supposed to yield a dual benefit: its goods and Services are intended to help to tackle environmental challenges and its Establishments should create new jobs. However, it is still unclear in empirical terms whether that really is the case. This paper investigates whether employment growth in ‘green’ establishments with ‘green’ products and services is higher compared to other establishments. Furthermore, the main factors determining labor demand in this field are analyzed.

Occupational and regional mobility as substitutes
10 April 2015
Job mobility offers opportunities for workers to obtain wage increases, but returns to job changes differ considerably. The authors argue that parts of this inequality result from a trade-off between occupational and regional mobility. Both mobility types offer alternative strategies to improve one’s labor market position; however, they each contain unique restrictions. High costs for regional mobility can thus evoke occupation changes, even though the resulting human capital devaluation leads to lower wage increases. The authors use linked retrospective life-course data for Germany (ALWA-ADIAB) and apply competing risks models to show that restrictions on one type of mobility drive individuals toward the other. Using fixed-effects regressions, we show that occupational mobility leads to lower wage increases compared to regional mobility.
