Unemployment,institutions, and interdependencies: identifying successful reforms

Labor market reforms, which reduce institutional rigidities, are assumed to be a well-suited approach to lower unemployment. However, it is still not perfectly clear which reforms actually lead to a fall in unemployment. One crucial issue is that reforms do not work in isolation, but have labor market effects which depend on other institutional factors. Such institutional interactions have rarely been considered in empirical macroeconomic studies in a systematic way, mainly due to model uncertainty. As a solution to this problem, a Bayesian model averaging approach is adopted in this paper to identify robust and significant institutional interactions for unemployment. Using a panel data-set for 17 OECD countries from 1982 to 2005, five robust and significant interaction terms are identified, and country-specific reform effects for the institutional indicators are derived.     

Verteilungswirkungen des Erneuerbare-Energien-Gesetzes

The ongoing economic criticism of the German Renewable Energy Act (EEG) recently started focusing on distributional effects, too. A team of authors at the Cologne Institute for Economic Research is worried about high costs for electricity consumers. They argue since electric power consumption is only slightly correlated with income, the fi nancial burden of the EEG is substantially higher for low-income households than for high-income households. This regressive effect is even increased since particularly high-income households have installed photovoltaic systems and thereby gain from green power subsidies. In contrast, other authors argue that this debate on distributional effects, while desirable, often scandalizes rather common issues of everyday economic events while ignoring the real EEG-induced redistribution effects, that is to say the EEG reallocation charge privilege for energy-intensive industries. These authors advise against drawing on partial analysis when discussing distribution-related issues of the EEG. A team of authors at the ZEW are concerned about the cost-effi ciency of the EEG which is the underlying reason for the recent discussions on distributional effects. The energy transition will entail large additional cost which will have to be carried. Increasing the effi ciency of governmental energy and climate policies will increase acceptance and attenuate distributional effects.     

Favor prevalence in emerging markets: A multi-level analysis

Favors are a medium of exchange for social capital. Social capital creates social, political, and economic benefits for individuals, organizations, communities, and societies around the world. Favors promote cooperation between individuals and are used to bond individual actors with other individuals, groups, communities, and institutions. Favors are prevalent in business in emerging markets because of the presence of institutional voids, limited social and geographic mobility, and strong reciprocity norms. Favors create benefits and liabilities for business organizations and their networks. They produce outcomes beyond the favor exchange process that can be characterized as productive or perverse. Despite their prevalence and importance, favors and their dynamics are not well understood. We explore the antecedents, content, process, and consequences of favors. We conclude our multi-level analysis of favors with a discussion of the “breakeven” point for favors—the point where favors tip from having a positive effect to having a negative effect on organization performance. We present an integrated framework to explain the dynamics of favors in emerging market business contexts, and develop propositions to guide future research.     

Neue Weltklimaordnung: Emissionshandel zwischen Staaten mit schrittweiser Klimagerechtigkeit

Der Diskussionsprozess um ein internationales Klimaabkommen und zur Klimagerechtigkeit dauert an. Die Autoren stellen ein Modell vor, das Klimagerechtigkeit schrittweise und mit marktbasierten Instrumenten umsetzt. Sie fordern eine internationale Weltklimaordnung, die auf der Weltklimakonferenz in Südafrika im Dezember 2011 umgesetzt werden soll.     

Communication in intergroup conflicts

Numerous studies suggest that communication may be a universal means to mitigate collective action problems. In this study, we challenge this view and show that the communication structure crucially determines whether communication mitigates or intensifies rent-seeking for pure public goods. We observe the effect of different communication structures in the context of a finitely repeated intergroup contest and demonstrate that conflict expenditures are significantly higher if communication is restricted to one's own group as compared to a situation with no communication. However, expenditures are significantly lower if open communication within one's own group and between rivaling groups is allowed. We show that under open communication intergroup conflicts are avoided by groups taking turns in winning the contest. Our results do not only qualify the role of communication for collective action but may also provide insights on how to mitigate the destructive nature of intergroup conflict and group rent-seeking.     

Rückkaufswert von Lebensversicherungen und Europarecht

This article deals with the calculation of surrender values of life assurances according to §169 Abs. 3 VVG and its conformity with European Law. The main focus is on the influence of this regulation on designing and offering assurance products by insurers of other Member States of the European Union under the right of establishment and the freedom to provide services. The problems with guaranteed surrender values and distribution of acquisition costs have, therefore, to be examined. Finally, the European principle that consumer information prevails over regulation of product design has to be discussed against the background of the European internal market.     

Innovator networks and regional knowledge base

Although network analysis has gained increasing attention over the last years, the literature on Regional Innovation Systems thus far has not embraced network methods. This study is an attempt to enrich the Regional Innovation System concept by applying social network methods to quantitatively assess the extent to which innovating actors in a region engage in systemic forms of knowledge exchange and collaboration. On the basis of a comparison of three rather different regional innovator networks, the paper suggests that regions with a strong knowledge base that are specialized in broad technology fields tend to have relatively fragmented network structures.
