Plant-Based Bioeconomy in Central Germany - Mapping of Actors, Industries and Places

Wilfried Ehrenfeld Frieder Kropfhäußer

in: Technology Analysis & Strategic Management , No. 5, 2017

Abstract

The bioeconomy links industrial and agricultural research and production and is expected to provide growth, particularly in rural areas. However, it is still unclear which companies, research institutes and universities make up the bioeconomy. This makes it difficult to evaluate the policy measures that support the bioeconomy. The aim of this article is to provide an inventory of relevant actors in the three Central German states of Saxony, Saxony-Anhalt and Thuringia. First we take an in-depth look at the different sectors, outline the industries involved, note the location and age of the enterprises and examine the distribution of important European industrial activity classification (NACE) codes. Our results underline the fact that established industry classifications are insufficient in identifying the plant-based bioeconomy population. We also question the overly optimistic statements regarding growth potentials in rural areas and employment potentials in general.

A Fresh Look at the Labor Market Height Premium in Germany

Frieder Kropfhäußer

in: Economics Bulletin , No. 3, 2016

Abstract

I use data from the German Socio-Economic Panel Study (SOEP) to analyze the relationship between height and wages in a sample of young German workers. My results show that the crude height wage premium documented in the literature is explained by unobserved heterogeneity on the sibling level. This contradicts the findings of a labor market height premium in Germany using OLS and Hausman-Taylor estimators as well as the Swedish finding of a height effect remaining after controlling for sibling fixed effects.

A Weighty Issue Revisited: The Dynamic Effect of Body Weight on Earnings and Satisfaction in Germany

Frieder Kropfhäußer Marco Sunder

in: Applied Economics , No. 41, 2015

Abstract

We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous findings, our dynamic models indicate an inverse u-shaped association between bmi and wages. As the implied maximum occurs in the ‘overweight’ category, the positive trend in weight may not yet constitute a major limitation to productivity. Further investigation points out a stronger association among young workers and workers with jobs that are less protected. Work satisfaction of young workers is associated with bmi beyond the effect of earnings.

Plant-based Bioeconomy in Central Germany - Mapping of Actors, Industries and Places

Wilfried Ehrenfeld Frieder Kropfhäußer

in: IWH Discussion Papers , No. 7, 2014

Abstract

The challenges facing the 21st century, presented by a growing global population, range from food security to sustainable energy supplies to the diminishing availability of fossil raw materials. An attempt to solve these problems is made by using the concept of bioeconomy. Plants, in particular, possess an important function in this context - they can be used either as a source of food or, in the form of biomass, for industrial or energy purposes. Linking industrial and agricultural research and production, bioeconomy provides growth potential, in particular in rural areas. The aim of this article is therefore to outline the status of plant-based bioeconomy in three states of Central Germany - Saxony, Saxony-Anhalt and Thuringia - and to compare this to German plant-based bioeconomy. We take an in-depth look at the different sectors and outline the industries involved, the location and age of the enterprises as well as the distribution of important NACE codes. In conclusion, we highlight the significant number of new or small enterprises and the high research and innovation rate of Central Germany. We also stress the future potential of Central German plant-based bioeconomy as well as the importance of a more plant-focusedview of the technology sector.

A Weighty Issue Revisited: The Dynamic Effect of Body Weight on Earnings and Satisfaction in Germany

Frieder Kropfhäußer Marco Sunder

in: SOEPpapers, No. 635 , No. 635, 2014

Abstract

We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous literature, the dynamic models indicate that there is an inverse u-shaped association between bmi and wages among young workers. Among young male workers, work satisfaction is affected beyond the effect on earnings. Our finding of an implied optimum bmi in the overweight range could indicate that the recent rise in weight does not yet constitute a major limitation to productivity.
