Relationships between a Firm's Short-run Costs of Production

This lesson focuses on just the per-unit cost curves, their shapes, and the relationships between them. As you will see, the marginal cost curve, itself shaped by the law of diminishing returns, intersects the average cost curves at their lowest points, which as we will see in later lessons enables producers to choose a level of output at which their per unit production costs are minimized, enabling firms to make decisions that allow them to optimize their output for profit-maximization.
