Rural-urban migration in d-dimensional lattices
The rural-urban migration phenomenon is analyzed by using an agent-based
computational model. Agents are placed on lattices which dimensions varying
from d=2 up to d=7. The localization of the agents in the lattice define their
social neighborhood (rural or urban) not being related to their spatial
distribution. The effect of the dimension of lattice is studied by analyzing
the variation of the main parameters that characterizes the migratory process.
The dynamics displays strong effects even for around one million of sites, in
higher dimensions (d=6, 7).Comment: 9 pages, 7 figures, to be published in International Journal of

An agent-based model to rural-urban migration analysis
In this paper we analyze the rural-urban migration phenomena as it is usually
observed in economies which are in the early stages of industrialization. The
analysis is conducted by means of a statistical mechanics approach which builds
a computational agent-based model. Agents are placed on a lattice and the
connections among them are described via an Ising like model. Simulations on
this computational model show some emergent properties that are common in
developing economies, such as a transitional dynamics characterized by
continuous growth of urban population, followed by the equalization of expected
wages between rural and urban sectors (Harris-Todaro equilibrium condition),
urban concentration and increasing of per capita income.Comment: 16 pages, 9 figure
