| Abstract: | In this discussion paper we develop a theory-based typology of innovation networks with a special focus on public-private collaboration. This taxonomy is theoretically based on the concept of life cycles which is transferred to the context of innovation networks as well as on the mode of network formation which can occur either spontaneous or planned. The taxonomy distinguishes six different types of networks and incorporates two plausible alternative developments that eventually lead to a similar network structure of the two types of networks. From this, important conclusions and recommendations for network actors and policy makers are drawn. -- |

| Abstract: | E-commerce has grown tremendously over the past decade. This paper focuses on E-commerce adoption within the franchising sector. We formulate various hypotheses on the factors that influence the adoption of an E-commerce strategy by franchisors, namely the percentage of company-owned stores in the network, network size and age, franchisor resources (franchising fees and franchising royalties), and the allocation of exclusive territories to franchisees. The empirical study relies on a sample of 486 franchise networks in the U.S. market. Our findings suggest that the percentage of company-owned stores and the brand image, as represented by network size, both exert a significant and positive impact on the adoption of an E-commerce strategy, whereas network age and franchising royalties exert a significant and negative impact on the adoption of such a strategy. These findings are discussed with respect to previous research results. |

| Abstract: | Using data from 92 indices of stock exchanges worldwide, I analize the cluster formation and evolution from 2007 to 2010, which includes the Subprime Mortgage Crisis of 2008, using asset graphs based on distance thresholds. I also study the survivability of connections and of clusters through time and the influence of noise in centrality measures applied to the networks of financial indices. |

| Abstract: | Substantial evidence suggests the behavioral relevance of social preferences and also the importance of social influence effects ("peer effects"). Yet, little is known about how peer effects and social preferences are related. In a three-person gift-exchange experiment we find causal evidence for peer effects in voluntary cooperation: agents' efforts are positively related despite the absence of material payoff interdependencies. We confront this result with major theories of social preferences which predict that efforts are unrelated, or negatively related. Some theories allow for positively-related efforts but cannot explain most observations. Conformism, norm following and considerations of social esteem are candidate explanations. |
