Final answer:
Diseconomies of scale is the standard that is based on historical data and includes all the inefficiencies that have crept into the operation over time. This situation occurs when a firm or a factory becomes so large that it becomes difficult to manage, resulting in unnecessarily high costs. An example of this is the plants in the old Soviet Union.
Step-by-step explanation:
The standard that is based on historical data and includes all the inefficiencies that have crept into the operation over time is known as diseconomies of scale.
This situation occurs when a firm or a factory becomes so large that it becomes difficult to manage, resulting in unnecessarily high costs due to communication failures and disruptions in the flow of work and materials.
An example of this is the plants in the old Soviet Union that were so large and inefficient, but continued to operate because government economic planners protected them from competition and ensured they would not make losses.
