That’s why easily-understandable oversimplified models are required before going into details even to start a meaningful social discussion. We present such a model that looking from the points of real balance, money and that is the most convenient – trade balance we can observe labor-deficit and labor-excessive stable equilibria sometimes (at some parameter values) simultaneously.
