We also allow for firms to differ in their technological characteristics …, investigate how this affects their propensity to collaborate and study the resulting network architecture. …

In this paper we introduce a stochastic network formation model where agents choose both actions and links. Neighbors … in the network benefit from each other's action levels through local complementarities and there exists a global …

communication or spillovers via the links between them. Linking decisions are based on network-dependent marginal payoff and a … the other agents in the network. Agents derive payoff from having access to the information of others through … network independent noise capturing exogenous idiosyncratic effects. Moreover, agents have a limited observation radius when …

This paper extends the existing literature on strategic R&D alliances by presenting a model of innovation networks with … intensity of cooperation and innovation. Within different knowledge regimes, we examine the structure of networks that emerge … and how firms perform within such networks. Our model replicates some stylised empirical results on network structure and …

Agents involved in the formation of a social or economic network typically face uncertainty about the benefits of … creating a link. However, the interplay of such uncertainty and risk attitudes has been neglected in the network formation … literature. We propose a dynamic network formation model that builds on standard microeconomic concepts of utility maximization …

network and graph theory. In a recent paper, Adamic and Glance (2005) report differences between the linking behavior of …The political blogosphere has recently been the focus of attention for social network analysis and applications of … politically conservative vs. politically liberal Web bloggers. We construct a simple agent-based network formation model which …

This paper analyses the effects of innovation networks on product and pro-cess innovation and sales growth of high … technology SMEs. Innovation net-works are positively related to both product and process innovation, i.e. know-ledge creation …. One exception is the negative effect of innovation networks with suppliers on product innovation. Older SMEs are more …

When workers send applications to vacancies they create a network. Frictions arise if workers do not know where other … workers apply to (this affects network creation) and firms do not know which candidates other firms consider (this affects … network clearing). We show that those frictions and the wage mechanism are in general not independent. Equilibria that exhibit …
