| Abstract: | Drawing on a large database of publicly announced R&D alliances, we track the evolution of R&D networks in a large number of economic sectors over a long time period (1986- 2009). Our main goal is to evaluate temporal and sectoral robustness of the main statistical properties of empirical R&D networks. By studying a large set of indicators, we provide a more complete description of these networks with respect to the existing literature. We find that most network properties are invariant across sectors. In addition, they do not change when alliances are considered independently of the sectors to which partners belong. Moreover, we find that many properties of R&D networks are characterized by a rise-and-fall dynamics with a peak in the mid-nineties. Finally, we show that such properties of empirical R&D networks support predictions of the recent theoretical literature on R&D network formation. |

| Abstract: | This paper shows that the abolition of state guarantees to publicly owned banks in Germany resulted in an increase in funding costs at German savings banks. Rather than being the result of increased market discipline, the increase in funding costs is shown to be driven by spillover effects from German Landesbanken who themselves had suffered from the abolition of guarantees and who spread their own cost increase through the public banking network. Higher funding costs and the resulting drop in bank charter values translated into higher risk-taking at German savings bank. |
