Sequential vs simultaneous schelling models: experimental evidence

Abstract

This work shows the results of experiments where subjects play the Schelling's spatial proximity model (1969, 1971a), in which choices are made sequentially, and a variation of it where the decision-making is simultaneous. The results of the sequential experiments are identical to Schelling's prediction: subjects finish in a segregated equilibrium. Likewise, in the variant of simultaneous decision the same result is reached: segregation. Subjects’ heterogeneity generates a series of focal points in the first round; the subjects in order to locate themselves use these focal points immediately, and as a result, the segregation takes place again.
