Final answer:
New entrants to an industry bring all of the following except a decline in per-unit product costs.
Step-by-step explanation:
New entrants to an industry bring all of the following except a decline in per-unit product costs. When new firms enter the industry, they typically bring new capacity, a desire to gain market share, a desire to gain market position, and new approaches to customer needs. However, a decline in per-unit product costs is not necessarily brought by new entrants to an industry. Instead, it may result from technological improvements or economies of scale.
