Long-run average curve (LAC) is U shaped because of economies and diseconomies of scale while the short run average curve (SAC) is U shaped because of the Law of Diminishing Returns. Discuss causes of economies of scale, of diseconomies of scale and of diminishing returns.
Causes of economies of scale
Technical and production advantages: use of more efficient large-scale machines and processes, specialization of equipment, and indivisibilities that spread fixed costs over more output.
Managerial and organizational specialization: hiring specialized managers and staff increases productivity per unit as output expands.
Bulk purchasing and input discounts: larger firms obtain lower per‑unit input costs through bulk buying and stronger bargaining power with suppliers.
Financial advantages: easier access to capital, lower interest rates, and ability to raise funds more cheaply than small firms.
Marketing and distribution efficiencies: spreading advertising, R&D, and distribution costs over a larger output and wider markets.
Learning and experience effects: improvements in processes and reductions in waste as cumulative output and worker experience grow.
Risk-bearing and diversification: larger firms can diversify products/markets, spreading fixed overhead and risk across activities.
Causes of diseconomies of scale
Managerial and communication problems: as firms grow, coordination and communication become harder, leading to delays, mistakes, and inefficiency.
Bureaucracy and rigidity: increased layers of hierarchy slow decision‑making and reduce responsiveness to problems or market changes.
Motivation and monitoring costs: worker alienation, reduced incentives, and higher supervision costs can lower per‑unit productivity.
Complexity and coordination costs: complex operations require more overhead for planning, control, and integration across units.
Input market constraints: large scale may push up input prices or lead to supply bottlenecks, raising average costs.
Congestion and diseconomies in supporting infrastructure: transport, storage, or utilities can become congested or more expensive at large scale.
Regulatory and compliance costs: larger firms may face stricter regulations and higher compliance costs per unit of output.
Causes of diminishing returns (short run)
Fixed factors: in the short run at least one input (e.g., capital or land) is fixed; adding more variable input (e.g., labor) eventually yields smaller additional output.
Overcrowding and congestion: too many workers or too much of a variable input relative to fixed capital leads to interference and lower marginal productivity.
Limited complementary capital: without proportional increases in machines or workspace, additional workers have less capital to work with, reducing marginal gains.
Management and coordination limits in the short run: supervising and organizing extra workers with fixed facilities becomes less efficient.
Physical and biological limits: in some production processes natural limits (soil fertility, machine throughput) make each extra input less effective.
