In this note, we extend the Goyal and Joshi’s model of collaboration networks in oligopoly to multi-market situations. We examine the incentive of firms to form links and the architectures of the resulting equilibrium networks in this setting. We then present some results on efficient networks.
We examine how parental health shocks affect children's non-cognitive skills. Based on a German mother-and-child data base, we draw on significant changes in self-reported parental health as an exogenous source of health variation to identify effects on outcomes for children at ages of three and six years. At the age of six, we observe that maternal health shocks in the previous three years have significant ...
Since 2007, the European cement and steel sectors have been characterized by substantial surplus production capacity. Hence re-investment in primary production of many materials remains limited and endangers the longer-term economic viability of many plants. Opportunities for innovation and modernization could overcome these challenges. They are linked to new demands for more efficient and lower-carbon ...
Seit 2007 ist die europäische Zement- und Stahlindustrie mit einer starken Nachfragereduktion konfrontiert, die zu Überkapazitäten führte. Aus diesem Grund kommt es nur in begrenztem Maße zu Reinvestitionen bei Produktionsanlagen. Dies gefährdet jedoch die längerfristige Wirtschaftlichkeit und den Erhalt vieler Anlagen. Neue Perspektiven für diese Branchen könnten sich aus Innovations-und Modernisierungsoptionen ...
This paper tests whether upstream R&D cooperation leads to downstream collusion. We show that a sufficient condition for identifying collusive behavior is a decline in the market share of RJV-participating firms. Using information from the U.S. National Cooperation Research Act, we estimate a market share equation correcting for the endogeneity of RJV participation and R&D expenditures. We find robust ...
The European Commission is currently overhauling the most important instrument for the regulation of cross-border flows of personal data, the Data Protection Directive of 1995 (Directive 95/46/EC). Among the most tedious legal issues is the use of personal data for secondary purposes. Such use occurs if data collected for one purpose (such as credit granting) are later used for another purpose (e.g. ...
