Theoretical investigation on the Schelling’s critical neighborhood demand
چکیده انگلیسی


• First proposed a theoretical counterpart of the Schelling’s agent-based model.
• Schelling’s critical neighborhood demand is theoretically derived.
• Critical condition is explained in terms of continuous chain reaction.
• Initial phase of the Schelling dynamics is explained by a random walk model.
• Two-room model is proposed as an aspatial version of the Schelling model.

We derived the critical neighborhood demand in the Schelling’s segregation model by studying the conditions for which a chain reaction of migrations of unsatisfied agents occurs. The essence of Schelling dynamics was approximated in two simplified models: (1) a random walk model for the initial stage of the migrations to illustrate the power-law behavior of chain reaction lengths under critical conditions, and (2) a two-room model for the whole process to represent a non-spatial version of segregation dynamics in the Schelling model. Our theoretical results showed good agreements with numerical results obtained from agent-based simulations.
