Abstract
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.
