How far is how far enough? Safety perception and acceptance of extra-high-voltage power lines in Germany

The results of a 2?×?2 factorial online experiment are reported. The first factor refers to the information on precautionary measures and the second factor on the information regarding the share of EMF exposure from extra-high-voltage power lines compared to overall EMF exposure measured in-house. The study is based on a community sample of 440 subjects. Information on the share of EMF exposure from extra-high-voltage power lines at the in-house overall EMF exposure has no statistically significant effect of safety distances and acceptance distances. Further findings indicate that communications of precautionary measures produce a countervailing effect: on average, subjects require a higher distance from their homes compared to those who were not informed about precautionary measures. However, there is also a positive effect of precautionary information on the acceptance belief. Subjects who received this information are, in average, less negative about the claim that compliance with the value limit is sufficient in order to agree with the construction of a power line. Possible explanations of the findings such as cognitive dissonance, negativity bias, and style of information processing are discussed.     

Investment liberalisation and firm selection process: A welfare analysis from a host-country perspective

We set up a theoretical model to analyze the implications of coordination of immigration policies among destination countries. The model contains two types of spillovers between destination countries: a terms-of-trade externality and a welfare-policy externality. We show that while coordination unambiguously increases welfare of the destination countries, the effects on the level of immigration and on the income distribution of natives are ambiguous. Thus, coordination among destination countries does not necessarily solve the global coordination problem of inoptimally low levels of migration.     

On the Determinants of Mandatory Works Councils in Germany

German works councils are often thought of as operating in all firms that exceed the basic size threshold (of five permanent employees) established under law. Drawing on a new large-scale, representative German data set, we report that only one-fifth of firms in our sample have works councils even if such firms do account for almost three-fourths of employment. The principal factors behind works council presence emerge as fairly conventional: firm size, firm age, branch plant status, the gender composition of the work force, and certain working arrangements. There are also signs of a close relation between workplace union density and council presence. However, some controversial causal links suggested in an earlier econometric literature receive little support.     

Trade Unions and Productivity: The German Evidence

This paper provides a brief review of the empirical evidence on union productivity effects in Germany. The influence of trade unions on productivity is the net effect of conflicting forces which can lead to higher or lower productivity. Although the German dual system of workers' representation via unions and works councils is quite favourable to the existence of productivity-enhancing 'voice' effects, various empirical studies have not been able to detect significant positive net effects of these institutions on productivity.
