Key Concepts
- Derived Demand: The demand for a factor of production (like labour) that arises from the demand for the final good or service it produces.
- Marginal Revenue Product (MRP): The additional revenue generated by employing one more unit of labour. Calculated as Marginal Physical Product (MPP) x Price (P) of output.
- Marginal Cost of Labour (MCL): The additional cost incurred by employing one more unit of labour. In perfect competition, MCL = wage rate.
- Wage Determination: The process by which the price of labour (wage rate) is set in a market, influenced by demand and supply.
