Our computer simulations show that the structural instability destroys an initial symmetric configuration. It means that the bifurcation of economic centres results to the generation of vortex regions corresponding to the so-called "parasitic" commodity flows which is an undesirable effect. We present the second interesting case of structurally unstable configuration with two connected null points which corresponds to the non-equilibrium price contour. This configuration transforms into structurally stable one without separatrix.
