This study investigates the usefulness of exponential random graph models (ERGM) to analyze the determinants of cross-regional R and D collaboration networks. Using spatial interaction models, most research on R and D collaboration between regions is constrained to focus on determinants at the...

Technological progress builds upon itself, with the expansion of invention in one domain propelling future work in linked fields. Our analysis uses 1.8 million U.S. patents and their citation properties to map the innovation network and its strength. Past innovation network structures are...

Informal inter-organizational networks provide manifold opportunities to organize the transfer of information, knowledge and technology between actors. Given their potential and their importance, the lack of theoretical discussion and empirical research on informal networks and their dynamics is...

Declining general trust has become a serious social issue in China in recent years. This paper attempts to understand and analyze this social phenomenon from a social interaction perspective. Based on a repeated prisoners ́dilemma game on networks, it finds that the evolution of general trust...

In this paper, the authors continue the pursuit of the self-coordination mechanism as studied in the El Farol Bar problem. However, in addition to efficiency (the optimal use of the public facility), they are also interested in the distribution of the public resources among all agents. Hence,...

Building on the philosophy of Charles Sanders Peirce, recent advances in biosemiotics have resulted into a concise framework for the analysis of signs in living systems. This paper explores the potential for economics and shows how biosemiotics can integrate two different research agendas, each...

What is the interrelationship among formal institutions, social networks, and new venture growth? Drawing on the theory of institutional polycentrism and social network theory, we examine this question using data on 637 entrepreneurs from four different countries. We find the confluence of weak...

Social interactions determine many economic behaviors, but information on social ties does not exist in most publicly available and widely used datasets. We present results on the identification of social networks from observational panel data that contains no information on social ties between...

Since the seminal contribution of Jackson & Wolinsky 1996 [A Strategic Model of Social and Economic Networks, JET 71, 44-74] it has been widely acknowledged that the formation of social networks exhibits a general conflict between individual strategic behavior and collective outcome. What has...
