ELEWI - Productivity in the life sciences

Funded by the German Federal Ministry of Education and Research (BMBF), the Chair
of Agricultural Production and Resource Economics and the HIS Institute for Higher Education Development engage in quantitative science studies. The aim of the project ELEWI is to create a comprehensive analysis of the productivity in the German life sciences... more

BioMonitor

The overall objective of the Monitoring the Bioeconomy (BioMonitor) project is to establish a statistics and modelling framework for the bioeconomy that is effective and robust. The framework will enable the quantification of the bioeconomy and its economic, environmental and social impacts in the EU and its Member States via a wide range of indictors. Interlinks with current standardisation work by the European Committee for Standardization related to bio-based products will be established from the outset of the project... more

BLIZ - Interactions between society, land use, ecosystem services and biodiversity in Bavaria until 2100

How will ecosystem services and biodiversity develop in Bavaria? The interdisciplinary joint project BLIZ takes a look into the future and designs new scenarios for a sustainable management of ecosystems in Bavaria. The aim of the group of six subprojects at four universities is to process concrete instructions and estimate possible uncertainties. BLIZ is supported and executed as part of the Bavarian network for climate research... more

Innovation and performance – evidence at micro level

Sauer, J. and H. Vrolijk (2019). Applied Economics

This empirical study aims to shed light on the link between innovation and economic performance at micro level. Based on a comprehensive survey among dairy and crop farms in the Netherlands we estimate a structural multi-stage model to deliver evidence on the effect of engagement and investment in innovation on the production of product, process and organizational or marketing innovations as well as on the effect of such innovations on farm level productivity. The results suggest various market and farm behaviour related factors to stimulate an increase in innovation engagement and production. Furthermore, the study reveals that indeed a greater innovation investment per unit (innovation input) leads to a higher probability of producing at least one successful product, process and/or organizational or marketing innovation (innovation output). The production of process and organizational or marketing related innovation leads to significant productivity gains. Various recommendations towards a more effective and efficient innovation policy are finally given.

The Preference for Sustainable Coffee and a New Approach for Dealing with Hypothetical Bias

Wuepper, D., Clemm, A. and P. Wree (2018). Journal of Economic Behavior & Organization

There is a large literature on the effects of sustainability labels. However, much of this research is based on stated preference methods, thus hypothetical bias must be dealt with. Hypothetical bias can be defined as the difference between stated, hypothetical behavior and actual behavior in the real market. We conducted an online choice experiment with coffees, of which some were labeled as water saving. To mitigate hypothetical bias, we used “cheap talk”. We find a statistically significant effect of a 6% higher choice probability and €1.30 higher willingness to pay for labeled coffee. However, we also implemented the water label in a real online shop, and we do not find this effect.

Does Information Change German Consumers’ Attitudes about Genetically Modified Food?

Wuepper, D., Wree, P. and G. Ardali (2018). European Review of Agricultural Economics

We use a choice experiment to investigate attitude heterogeneity regarding genetically modified food and how it is affected by the provision of balanced information. For the analysis, we use a generalised multinomial and a latent class logit. The consumers who are more accepting of genetic modifications are younger, less educated and less concerned about their nutrition. The average effect of our provided information is negligible. However, the initially less opposed become slightly more opposed. Our results thus do not support the view that a lack of information drives consumer attitudes. Instead, attitudes seem to mostly reflect fundamental preferences. We discuss implications for research and policy.
