Expectations form the basis of economic decisions of market participants in an uncertain world. Sentiment indicators reflect those expectations and thus have a proven track record for predicting economic variables. However, respondents of surveys perceive the world to a large extent with the help of media. So far, mainly very crude media information, such as word-count indices, has been used in the ...
Top-down computable general equilibrium (CGE) models are used extensively for analysis of energy and climate policies. Energy-intensive industries are usually represented in top-down economic models as abstract economic production functions, commonly of the constant-elasticity-of-substitution (CES) or translog functional form. This study explores methods for improving the realism of energy-intensive ...
In Eastern Germany, wage differentiation between firms has clearly grown, parallel to individual wage differentials. Nevertheless, the wage spread between firms is still much less than in Western Germany. In this paper, a non-parametric decomposition is used to analyze the difference between the wages spread in the two parts of Germany. Only part of the difference can be explained by different economic ...

In the light of recent market developments in academic publishing, we argue in this essay that the discourse about open access must include a discussion about research infrastructure and innovation in academic publishing.
