In this paper, we open up the black box that has been the introduction of open practices into firms’ commercial R&D strategies. Most of the existing research on the phenomenon of open innovation focuses on its interorganizational aspects. In contrast, the effect that the opening of boundaries...

In this paper, I describe and analyze the phenomenon of informal development collaborationbetween firms in the field of embedded Linux, a type of open source software. Toexplain the observed phenomenon of voluntary revealing, I develop a duopoly model ofquality competition. The central...

The link between firms engaging in open source software (OSS) development and the OSScommunity is established by individual developers. This linkage might entail a principalagentissue due to the developer’s double allegiance to firm and OSS community, and exposethe firm to the risk of losing...

This paper provides a quantitative study (N = 268) of patterns of free revealing offirm-developed innovations within embedded Linux, a type of open source software (OSS). Ifind that firms, without being obliged to do so, contribute many of their own developmentsback to public embedded Linux...

Network externalities spur the growth of networks and the adoption of network goods intwo ways. First, they make it attractive to join a network with a large installed base.Second, they make it attractive for network members to actively recruit new members.Despite indications that this “peer...

For the reliable communication network design (RCND) problem links areunreliable and for each link several options are available with dierent reliabilitiesand costs. The goal is to nd a cost-minimal communicationnetwork design that satises a pre-dened overall reliability constraint.This paper...

OptiNet ist ein objektorientiertes Optimierungswerkzeug für die Lösung von baumförmigen Netzwerkproblemen mit Hilfe von naturanalogen Optimierungsverfahren. In OptiNet können verschiedene naturanaloge Optimierungsverfahren mit unterschiedlichen Problemrepräsentatio-nen (charakteristische...

This paper investigates GA approaches for solving the reliable communicationnetwork design problem. For solving this problem a graph withminimum cost must be found that satises a given network reliabilityconstraint. To consider the additional reliability constraint dierent approachesare...

This paper sheds some light on the debate concerning evolutionary search using Prüfer numbers, and explains some of the controversial results. Previous work has shown that Prüfer numbers have low locality. Furthermore, it has been shown elsewhere that the locality of the Prüfer number depends...
