This paper aims to analyze the equilibrium overconsumption in social networks. We
cite two characters (jealousy and keeping up with Joneses) into utility function to
express externality of consumption. We also present a social network which is formed
by a dynamic process and find out the equilibrium outcome and the gap between
competitive equilibrium and social planner solution in a representative social network.
Keywords: Jealousy, Keeping up with Joneses, Social Networks.
