The Enemy of My Enemy Is My Friend: A New Condition for Stable Networks
This paper examines if an ancient principle, ``the enemy of my enemy is my friend,'' is a good predictor of group formation. I model coalition formation as a static network formation game with complementarities between a pair of adjacent nodes. I demonstrate that the ancient proverb is indeed a sufficient condition for the existence of a stable network that is also efficient.
