We introduce a simple two-stage game of endogenous network formation and information sharing for reasoning about the … optimal design of social networks like Facebook or Google+. We distinguish between unilateral and bilateral connections and … then we study how the network design and the utility specifications affect welfare. Surprisingly, we find that in general …

explanation for many core-periphery structures observed in real life social networks. -- Network Formation ; Heterogeneity … solely on the types of the two end agents. Core periphery networks are defined as networks in which the agents' set can be … over the other, controlling for path length. An exhaustive analysis shows that core periphery networks, in which the …

We analyze R&D collaboration networks in industries where firms are competitors in the product market. Firms' benefits … characterization of both equilibrium networks and endogenous production choices in the form of a Gibbs measure. We analyze the … efficient network maximizing social welfare, and find that the efficient graph is either empty, complete or shows a strong core …

We investigate the network topology of a comprehensive data set of the world-wide population of corporate entities. In … themselves both at the level of national networks and at the worldwide aggregated level. …

This paper studies a noncooperative model of network formation. Built upon the two-way flow model of Bala and Goyal … number of his links. This assumption results in the fact that a large set of Nash networks are disconnected and consist of … components of different sizes, a feature that resembles that of real-world networks. Discussions on this insight are provided. …

Most literature in strategic network formation shows that there is a substantial tension between stability and … (2000a) and De Jaegher and Kamphorst (2015). Specifically, I show that every link receiver in a Nash network serves as an … fine-detail characterization of effiicient networks. …

The paper proposes a game of weighted network formation in which each agent has a limited resource to form links of …, uniquely predicts the equilibrium values of each agent's network investment and utility level, as well as the ratio of any two …

We present a new approach to the study of networks where the formation of links is driven by unilateral initiative of … nodes. First, we propose a mathematical description of the extreme introvert and extrovert model (XIE), a dynamic network … generalization of the model in which intermittent states can make the evolution of connectivity slower. In this class of networks …

I then estimate the model using a network of coinventors and …This paper analyzes the formation of networks in which each agent is assumed to possess some information of value to … the other agents in the network. Agents derive payoff from having access to the information of others through …

In our model, agents are endowed with their own multidimensional characteristics and their … stable networks, and analyze how they are related to the way agents measure social distances.
