TY - JOUR T1 - Selection, Socialization and Stable Networks TT - Ön Seçim, Sosyalleşme ve Stabil Ağlar AU - Çengelci, Murat Ali PY - 2025 DA - July Y2 - 2024 DO - 10.18825/iremjournal.1532799 JF - International Review of Economics and Management JO - IREM PB - Gökhan ÖZER WT - DergiPark SN - 2148-3493 SP - 1 EP - 30 VL - 13 IS - 1 LA - en AB - When individuals make decisions or choose behaviors, they are affectedby the decisions or behaviours of their friends. In turn, individuals oftenchoose their friend based on similarities in these decisions and behaviours.Kandel (1978) provide emprical evidence that these aspects are present infriendship networks and refers them as socialization and selection, respectively.In this paper, we consider a model of friendship network which reflects bothaspects. To capture socialization, we consider a network game where agentswith different types choose an action on a certain behaviour to coordinate theiraction both with their type and actions of friends in network. Agent, then,decide their friends based on the utility of network game under unique Nashequilibrium. We show certain class of networks are pairwise stable. KW - Selection KW - Socialization KW - Social Network Theory N2 - İnsanlar tercihler yaparken veya davranışlarına karar verirken arkadaşlarının karar ve tercihlerinden etkilenirler. Öte yandan insanlar arkadaşlık kararlarını verirken de arkadaşlarının tercih ve kararlarından etkilenirler. Kandel (1978) araştırmasında bu iki yönlü etkinin var olduğunu ampirik olarak göstermiş ve bu etkilere sosyalleşme ve ön seçim olarak adlandırmıştır. Bu makalede biz insanların arkadaşlıklarına karar verdikleri bir sosyal ağ modeli öneriyoruz. Sosyalleşme etkilerini çalışabilmek için bireylerin tercih ve kararlarını arkadaşları ile koordine ettiği bir ağ oyunu modelliyoruz. Ön seçim etkilerini çalışabilmek içinse bireylerin ağ oyununda tek olduğunu gösterdiğimiz Nash Dengesine dayalı olan fayda fonksiyonuna göre arkadaşlık kararlarını verdiklerini varsayıyoruz. Belli bazı sosyal ağların da stabil ağ olduğunu gösteriyoruz. CR - Ballester, C., A. Calvó-Armengol, and Y. Zenou (2006). Who’s Who in Networks. Wanted: The Key Player.
