Spatial patterns of segregation : a simulation of the impact of externalities between households

  • Usually, in monocentric city models, the spatial patterns of segregated ethnic groups are assumed to be ring-shaped, whereas in the 1930ies Hoyt showed that empirically wedge-shaped areas predominate. In contrast to Rose-Ackerman.s discussion of the in.uence within a ring-shaped pattern which the aversion which different households in the context of racism have, Yinger showed that, depending on the population mix, a wedge-shaped pattern may arise if it is border length which causes the spatial pattern. In this contribution, a simulation based on a monocentric city model with two or more different household groups is used to derive spatial patterns. Wedge-shaped segregation is shown to be the result of positive externalities among similar households. Differences between households only lead to ring-shaped patterns if the e¤ect of a city center on spatial structure dominates neighborhood e¤ects. If more than two groups of households are being considered, mixed patterns of concentric and wedge-shaped areas arise.
