The standard Urban Economics model (Alonso, Muth, Mills) describes analytically an equilibrium of household location in urban areas. We build an agent-based model able to reach this equilibrium in a dynamic way. This allows us to simulate the development of a city by a combination of heterogeneous agents (based on income and preferences for the amenities), transport time cost and amenities locations. We explore the conditions under which non-trivial residential patterns and urban social structure can be obtained. [less ▲]

Linking microscopic and macroscopic behavior is at the heart of many natural and social sciences. This apparent similarity conceals essential differences across disciplines: Although physical particles are assumed to optimize the global energy, economic agents maximize their own utility. Here, we solve exactly a Schelling-like segregation model, which interpolates continuously between cooperative and individual dynamics. We show that increasing the degree of cooperativity induces a qualitative transition from a segregated phase of low utility toward a mixed phase of high utility. By introducing a simple function that links the individual and global levels, we pave the way to a rigorous approach of a wide class of systems, where dynamics are governed by individual strategies.
