Many data situations require the consideration of network effects among the cross-sectional units of observation. In … this paper, we present a generalized panel model which accounts for two features: (i) three types of network effects on the … error components, and (ii) higher-order network effects due to ex-ante unknown network-decay functions or the presence of …

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