The migratory system of Berlin after unification in the context of global restructuring.

"The migration process within the politically unified Berlin seems to be an excellent indicator in how far these two sub-systems have already merged socially and economically or have restructured under the present global economic stress." The authors pose several questions regarding the behavior of an intraurban migration system. "An origin-destination constrained interaction model and descriptive statistics are used to address these questions. Preliminary results provide sufficient evidence to disaggregate the complexity of the migration flows into two levels comprised of local and global systems."
