Derived demand

In economics, derived demand is demand for a factor of production or intermediate good that occurs as a result of the demand for another intermediate or final good. In essence, the demand for one is dependent on that whose demand its demand is derived from. For example, if the demand for a good such as wheat increases, then this leads to an increase in the demand for labour. For another example, demand for steel leads to derived demand for steel workers, as steel workers are necessary for the production of steel. As the demand for steel increases, so does its price. The increase in price means manufacturers of steel can gain more in revenue if they produce more steel, thus leading to a higher demand for the resources involved in producing steel.
