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...

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...

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...

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

We present a model of imperfect price competition where not all firms can sell to all consumers. A network structure models the local interaction of firms and consumers. We find that aggregate surplus is maximized with a fully connected network, which corresponds to perfect competition, and...

I study a one-way flow connections model in which players are heterogeneous with respect to values and the costs of establishing a link. I first show that values and costs asymmetries are crucial in determining the level of connectedness of a network. Interestingly, unconnected equilibria are...

When workers send applications to vacancies they create a network. Frictionsarise because workers typically do not know where other workers apply to and firmsdo not know which candidates other firms consider. The first coordination frictionaffects network formation, while the second coordination...

This paper employs a weighted network analysis to study the empirical properties of the world trade web and their evolution over time. We show that most countries are characterized by weak trade links; yet, there exists a group of countries featuring a large number of strong relationships, thus...

Over the past four decades the High Performing Asian Economies (HPAE) have followed a development strategy based on the exposure of their local markets to the presence of foreign competition and on an outward oriented production. In contrast, Latin American Economies (LATAM) began taking steps...
