The importance of social and economic networks has meanwhile been widely acknowledged throughout social sciences … about job openings, bargaining power etc. Given these beneficial aspects of networks, the stability is in question: How do … networks change when agents follow incentives for profitable network positions? This question serves as a leitmotif for this …
