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.

Social networks, be it on the internet or in real life, facilitate information flows. We model this by giving agents … incentives to link with others and receive information through those links. We consider networks where agents have an incentive … to confirm the information they receive from others. Our paper analyzes the social networks that are formed. We first …
