Producer’s damage as a function of deviations of market-price and market-supply from its equilibrium values (Cobweb model as example)

Definition of new economic parameter "average dynamic damage" is offered, which is under-stood as a difference between potential profit of a commodity producer at an equilibrium condition of the market and "nonequilibrium" (i.e. real) profit. Formulas for the approached estimation of a range of change of this parameter are proved at a nonequilibrium condition of the market. Geometrical interpretation of "damage of a commodity producer " is offered.
