Friendship selection
نویسنده
چکیده
We model the formation of friendships as repeated cooperation within a set of heterogeneous players. The model is built around three of the most important facts about friendship: friends help each other, there is reciprocity in the relationship and people usually have only a few friends. In our results, we explain how similarity between people affects the friendship selection. We also characterize the long-run friendship network and illustrate how friendships emerge given the random process by which people meet each other.

متن کاملAdolescent girls' friendship networks, body dissatisfaction, and disordered eating: examining selection and socialization processes.
Previous research has shown that adolescent girls tend to resemble their friends in their level of body dissatisfaction and disordered eating.

The current study used longitudinal stochastic actor-based modeling to simultaneously examine these two p...
