Probabilistic flows of inhabitants in urban areas and self-organization in housing markets of a city designated by ordinance

Abstract (in Japanese) (See Japanese page) 
(in English) We propose a very simple probabilistic model to
explain the rent distribution of housing market in Sapporo city.
We modify the mathematical model proposed
by Gauvin et.al. (2012).
In their mathematical modeling, they utilized several assumptions
to describe the decision making of each inhabitant in Paris.
Namely, they assumed that the intrinsic attractiveness of a city
depends on
the place and there exists a single peak at the center.
They also used the assumption that each inhabitant tends to choose the place where the other inhabitants
having the similar or superior income to himself/herself are living.
In order to find the best possible place to live,
each buyer in the system moves from one place to the other according to
the transition (aggregation) probability described by the above two assumption and
makes a deal with the seller who presents the best condition for the buyer.
They concluded that the resultant self-organized rent distribution is constant with
the corresponding empirical evidence in Paris.
However, it is hard for us to apply their model directly
to the other cities having plural centers (not only a single center as in Paris).
Hence, here we shall modify the Gauvin's model to include
the much more detail structure of the attractiveness by taking into account the empirical data
concerning the housing situation in Sapporo city.
We also consider the competition between
two distances, namely, the distance between house and center, and the distance
between house and office.
Computer simulations are carried out to reveal the
self-organized structure appearing in the rent distribution.
We also compare
the resultant distribution and empirical rent distribution in Sapporo as
an example of cities designated by ordinance.
