The Long Run Average Cost Curve represents what aspect of production?

The Long Run Average Cost Curve (LRAC) illustrates the lowest possible average cost of production at varying levels of output, reflecting the concept of economies of scale. In the long run, firms have the flexibility to adjust all their inputs, including technology and production processes. This adaptability allows companies to achieve the most efficient scale of production, minimizing costs per unit.

As production increases, economies of scale may first lead to a decline in average costs due to factors like increased specialization and more efficient use of resources. Eventually, however, firms may experience diseconomies of scale where costs start to increase again due to factors like managerial inefficiencies or overuse of resources. The LRAC curve, therefore, highlights the lowest average cost achievable across different levels of output, helping firms identify optimal production levels for maximizing profitability while minimizing costs. This understanding is crucial for making informed production and pricing decisions.
