in the context of a network formation game (where links can be interpreted as friendships in a social network … acquiring the information with others) through a percolation process over the equilibrium network. Privacy concerns are modeled … mixed-strategy equilibria. Our two main results show that, as in many real-life examples, the resulting equilibrium networks …
