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 …

economy. Our efficiency analysis further allows us to study the effect of competition on innovation in R&D intensive … portfolio of ideas that changes over time through innovations and knowledge spillovers between collaborating firms. The … destruction leading to the obsolescence of existing technologies. We quantify the innovation gains from collaborations, and show …

network structure. We provide a general characterization of both equilibrium networks and endogenous production choices, and … compare it to the efficient network architecture. 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. -- Bonacich centrality …

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 …

We develop a network model whose links are governed by banks' optmizing decisions and by an endogenous tâtonnement … evolution of the network configuration under various prudential policy regimes, to measure banks' contribution to systemic risk …

We investigate the network topology of a comprehensive data set of the world-wide population of corporate entities. In …

agents form a core-periphery network, with core members acting as conduits of information on behalf of their stakeholders …, effectively intermediating all transmissions of information within the network. …

We introduce a simple two-stage game of endogenous network formation and information sharing for reasoning about the … then we study how the network design and the utility specifications affect welfare. Surprisingly, we find that in general … "babblers" or "friends", irrespective of whether the network is unilateral or bilateral, in equilibrium, targeted information …

We select the minimal case of a bipartite network where we have two groups of nodes … extreme Thouless effect in this model, i.e. a mixed-phase transition at which the order parameter, here given by the network …
