We study lobbying in a setting in which decision-makers share resources in a network. Two opposing interest groups …-makers' ideologies as well as the network structure. We characterize the lobbying strategies in various network settings and show that a …

We define a general class of network formation models, Statistical Exponential Random Graph Models (SERGMs), that nest …' (including ERGMs) parameters estimated from the observation of a single network are consistent (i.e., become accurate as the … exponentially slow mixing times for many specifications, we show that by reformulating network formation as a distribution over the …

Most network games assume that the best response of a player is a linear function of the actions of her neighbors … network models in the existing literature, including those with nonlinear best responses, can be transformed into games with … produce a unified framework that provides conditions for existence and uniqueness of equilibrium for most network games with …

This paper applies for the first time power index analysis to the famous Krackhardt’s kite social network by imposing a … weighted voting game on the given network structure. It compares the results of this analysis, derived by applying the Public … traditional centrality measures are rather a first approximation for evaluating the power in a network as they considerably …

We show that prominent centrality measures in network analysis are all based on additively separable and linear … treatments of statistics that capture a node's position in the network. This enables us to provide a taxonomy of centrality …

This paper analyses a simultaneous game of network formation and information acquisition where the benefit structure is … such that the benefit that an agent derives from the network she is located in depends on the maximum information that … someone in her neighbourhood, including herself, acquires. It turns out that in equilibrium star network emerges as the unique …

In the benchmark model of Bala and Goyal (2000) on network formation, the equilibrium network is asymmetric and unfair … impacts the network formation process by increasing the asymmetry of networks but does not decrease the level of fairness nor …

Although the linear-in-means model is the workhorse model in empirical work on peer effects, its theoretical properties are understudied. In this paper, we investigate how social norms affect individual effort, aggregate effort, and welfare. While individual productivity always positively...
