Summary
Labour market forces involve the interaction of demand and supply in determining wages and employment levels. Derived Demand — demand for labor based on the demand for goods and services. Example: Firms hire workers to produce goods that are in demand. Marginal Revenue Product (MRP) — the additional revenue generated by employing one more worker. Example: Calculated by multiplying the marginal product of labor by the price of the product. Transfer Earnings — the minimum payment required to keep a worker in their current job. Example: The area under the labor supply curve up to the equilibrium wage. Economic Rent — any payment to labor above transfer earnings. Example: The triangular area above the equilibrium wage in a graph.
