This paper provides an analysis of aggregate behavioral outcomes when individual utility exhibits social interaction effects. We study generalized logistic models of individual choice which incorporate terms reflecting the desire of individuals to conform to the behavior of others in an environment of noncooperative decisionmaking. Laws of large numbers are generated in such environments. Multiplicity of equilibria in these models, which are equivalent to the existence of multiple self-consistent means for average choice behavior, will exist when the social interactions exceed a particular threshold. Local stability of these multiple equilibria is also studied. The properties of the noncooperative economy are contrasted with the properties of an economy in which a social planner determines the set of individual choices. Finally, the likelihood function based on the theoretical model is given and conditions for the econometric identifiability of the model is established.
[On the possibility of ongoing secret negotiations between the U.S. and North Korea] I am always wondering if my chain is being yanked. It could also mean Kim is trying to undermine Moon, who positions himself as a broker between the U.S. and North Korea. These two potential explanations are not mutually exclusive.
