Query: Hipsters and the Cool: A Game Theoretic Analysis of Social Identity,
  Trends and Fads   Cultural trends and popularity cycles can be observed all around us, yet our
theories of social influence and identity expression do not explain what
perpetuates these complex, often unpredictable social dynamics. We propose a
theory of social identity expression based on the opposing, but not mutually
exclusive, motives to conform and to be unique among one's neighbors in a
social network. We then model the social dynamics that arise from these
motives. We find that the dynamics typically enter random walks or stochastic
limit cycles rather than converging to a static equilibrium. We also prove that
without social network structure or, alternatively, without the uniqueness
motive, reasonable adaptive dynamics would necessarily converge to equilibrium.
Thus, we show that nuanced psychological assumptions (recognizing preferences
for uniqueness along with conformity) and realistic social network structure
are both necessary for explaining how complex, unpredictable cultural trends
emerge.
