A degree-distance-based connections model with negative and positive externalities

Möhlmeier, Philipp; Rusinowska, Agnieszka; Tanimura, Emily - 2013

We develop a modification of the connections model by Jackson and Wolinsky (1996) that takes into account negative … externalities arising from the connectivity of direct and indirect neighbors, thus combining aspects of the connections model and …-distancebased connections model with both negative and positive externalities. Our analysis shows how the introduction of negative externalities …

Confirming Information Flows in Networks

Billand, Pascal; Bravard, Christophe; Kamphorst, Jurjen J.A. - Volkswirtschaftliche Fakultät, … - 2013

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...
