correspondingly smaller circle of consumers.(654) This last is true especially when the price, without having suffered any absolute change, has become relatively too low, on account of an increase in the cost of production.(655) Chapter CX. Different Cost Of Production Of The Same Goods. Most goods are produced at the same time, but under different circumstances, at a very different cost. In order to estimate the influence of this fact upon price, we must distinguish between those commodities the cheapest manner of the production of which may be extended at pleasure, and those in the production of which it is necessary, in order to satisfy the aggregate want of them, to call in the dearest mode of production to aid the cheapest. In the former instance, the price of commodities is naturally regulated by the least cost of production. The person who is unable to sustain this competition permanently, would do a great deal better to abandon the industry altogether; for it is not in his power to raise the price by diminishing the supply; more powerful rivals would then only need to correspondingly increase theirs.(656) If the same law were applicable, in the latter case, producers placed in a less favorable situation would be compelled to immediately abandon the market. The market, in consequence, would no longer be able to provide for the aggregate need; and the price of the commodity would continue to rise until the producers who had been driven from the market returned to it again. Hence, here, price in the long run is determined by the cost of the production of the commodity, produced under the least advantageous conditions, while such production is necessary in order to satisfy the aggregate need. The person engaged in production under more advantageous conditions receives in the same price of the goods, which are cheaper to him, an excess of profit; one which is greater in proportion as his situation, _vis-a-vis_ of production, is superior to that of his less favored competitors.(657)(658) Section CXI.
