A situation in which the proportionate increase in inputs leads to an equal proportionate increase in outputs, meaning costs and outputs scale equally as production expands.

Diseconomies of Scale

A situation where a business's cost per unit increases as it produces more items, due to inefficiencies that arise with scaling up production.

Plant Size

Refers to the physical capacity or output level of a manufacturing or production facility.

Output Levels
