In markets with strong scale economies, why is catch-up by followers often economically prohibitive?

• A. They can easily match prices with no disadvantage.
• B. They face higher per-unit costs at volumes needed to match the leader.
• C. They can undercut price without regard to costs.
• D. They gain immediate market share.

Answer: (B)

In markets with strong scale economies, what matters most is how costs change as you produce more. Large fixed costs and process efficiencies mean average cost falls as output increases. To catch up with a leader who already operates at a huge scale, followers must reach a similar level of production. That requires substantial upfront investment and time to grow volumes. Until they hit that scale, their per-unit costs stay higher than the leader’s, so competing on price would erode profits. This makes catch-up economically prohibitive: the cost gap at the needed volumes is too large to overcome quickly or easily.

Other ideas don’t fit because they ignore the cost structure driving the barrier. Simply matching prices without the scale disadvantage overlooks why those prices would be unprofitable for the follower. Undercutting prices without regard to costs isn’t sustainable when you haven’t achieved scale, and claiming immediate market share ignores the reality that scale and the associated cost advantages take time to build.
