In this type of market, supply normally is very elastic. Either in the short or long run, supply is responsive to demand in the market for manufactures. It is easier to change the composition of a firm’s output than it is to change the production of a mine or a plantation. When changes in demand are not rapid, gross profits from one plant can be siphoned off and invested in something different. When business is good, moreover, there will be continual new investments so that productive capacity is adapted to meeting changing requirements. Workers themselves may not be aware of changes in the final commodities to which their work contributes, and the level of wages for any grade of factory labor is little affected by the fortunes of a particular market.
