Title: Spatial economic models of social interactions Authors:  Pascal Mossay - Kyungpook National University (Korea, South) [presenting]
Abstract: An economic approach to social interactions over the space is introduced. We explain how external effects arising from social interactions can lead individuals to cluster in a spatial economy. For this, we exploit the notions of spatial trade-off and economic equilibrium. This allows us to describe how the model parameters affect spatial patterns and to discuss issues related to the the social optimum and multiple equilibria. A particular attention is devoted to the spatial structure underlying the economic models.
