. He proposed that central planning boards set prices through "trial and error", making adjustments as shortages and surpluses occur rather than relying on a free price mechanism. Under this system, central planners would arbitrarily pick a price for products manufactured in government factories and raise it or reduce, depending on whether it resulted in shortages or gluts. After this economic experiment had been run a few times, mathematical methods would be employed to plan the economy: if there were shortages, prices would be raised; if there were surpluses, prices would be lowered.

With the utilization of this idea, Lange claimed, a
