While the physics/applied mathematics approach is capable of reproducing most observed networks, it does …We survey the literature on social networks by putting together the economics, sociological and physics … not explain why they emerge. On the contrary, the economics approach is very precise in explaining why networks emerge but …

We study a model that integrates productive and socialization efforts with network choice and parental investments. We … effort, but that solving only the investment problem can exacerbate the misallocations due to network choice, to the point … that it may generate an even lower social welfare if one of the networks is sufficiently disadvantaged. We also study the …

We consider a dynamic model of network formation where agents form and sever links based on the centrality of their … transition from dissortative to assortative networks. This effect can shed light on the distinction between technological and … social networks as it gives a simple mechanism explaining how and why this transition occurs. …

We provide an overview on networks in economics. We first look at the theoretical aspects of network economics using a … game-theoretical approach. We derive some results on games on networks and network formation. We also study what happens … empirical-relevant questions by mainly focusing on labor-market networks and crime networks. We provide some empirical evidence …

The aim of this paper is to provide a tractable model where both socialization (or network formation) and productive … efforts can be analyzed simultaneously. This permits a full-fledged equilibrium/welfare analysis of network formation with …

Pairwise stability (Jackson and Wolinsky, 1996) is the standard stability concept in network formation. It assumes … agents are farsighted, related stability concepts have been proposed. We design a simple network formation experiment to test …

We develop a dynamic network formation model that can explain the observed nestedness in real-world networks. Links are … identify the networks to which the network formation process converges and find that they are nested split graphs. We … by real-world networks. Using four different network datasets, we empirically test our model and show that it fits well …

We present an economic experiment on network formation, in which subjects can decide to form links to one another … Goyal (2000).
