Such enhancements of the market price are evidently the effect of natural causes which may hinder the effectual demand from ever being fully supplied, and which may continue, therefore, to operate for ever.

A monopoly granted either to an individual or to a trading company has the same effect as a secret in trade or manufactures.

The monopolists, by keeping the market constantly understocked, by never fully supplying the effectual demand, sell their commodities much above the natural price, and raise their emoluments, whether they consist in wages or profit, greatly above their natural rate.
