Concept:A corporate merger combines two or more firms to operate on a larger scale and gain cost-saving advantages.
Explanation:When companies merge, they pool their assets, staff, and technology.
This allows the new firm to produce in larger quantities and spread fixed costs over more units.
As output rises, the average cost of production falls.
This fall in per-unit cost is known as economies of scale.
The main specific reason firms pursue mergers is therefore to enjoy this cost advantage and become more competitive.
Profit maximization is a general business goal, but the chief objective of a merger is to enhance economies of scale.
