   Exploring the polycentric city with multi-worker households: An agent-based microeconomic modelLemoy, Rémi  ; ; in Computers, Environment and Urban Systems (2017), 62 We propose an agent-based dynamics which leads an urban system to the standard equilibrium of the Alonso, Muth, Mills (AMM) framework.

[more ▼] We propose an agent-based dynamics which leads an urban system to the standard equilibrium of the Alonso, Muth, Mills (AMM) framework. Starting for instance from a random initialization, agents move and bid for land, performing a kind of local search and finally leading the system to equilibrium rent, density and land use. Agreement with continuous analytical results is limited only by the discreteness of simulations. We then study polycentrism in cities with this tool. Two job centers are introduced, and the economic, social and environmental outcomes of various polycentric spatial structures are presented. We also introduce two-worker households whose partners may work in different job centers. When various two-worker households are mixed, polycentrism is desirable, as long as the centers are not too distant from each other. The environmental outcome is also positive, but housing surfaces.increase. (C) 2016 Elsevier Ltd. All rights reserved.

[more ▼] In this work, we exploit the power of the Alonso-Mills-Muth (AMM) urban economics model and show that various utility functions and plausible conditions offer alternative explanations of house- holds’ location by income within a city. These include the existence of a “rich” center and more complex socio-spatial urban forms, for instance alternating a rich center, poor suburbs and a rich outer ring, which have not yet been derived from the AMM model to our knowledge. In doing so we combine analytical ideas and illustrations by the means of an agent-based model. The hypothesis of a central or non-central amenity is also studied, leading to different insights on the issue.

[more ▼] 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.
