Firms are attracted to expanding industries by
A) normal profits.
B) economic profits.
C) cost structure.
D) revenue structure.
The correct answer and explanation is:
The correct answer is:
B) economic profits.
Explanation:
Firms are generally attracted to expanding industries because of the opportunity to earn economic profits.
Economic profits occur when a firm’s total revenue exceeds the total costs, including both explicit and implicit costs (opportunity costs). This is different from normal profits, which occur when total revenue just covers all explicit and implicit costs, resulting in zero economic profit but normal accounting profit.
When an industry is expanding, it means demand for its products or services is growing. This growth often leads to higher prices or larger sales volumes, allowing firms already operating in the industry to earn economic profits. The presence of economic profits signals that there are opportunities to make returns above the typical or normal levels that cover all costs.
This attracts new firms into the industry because:
- Profit motive: New entrants want to capture some of the economic profits being earned.
- Increased output and innovation: Expansion often creates room for innovation, economies of scale, and greater efficiency.
- Market signals: Economic profits indicate unmet demand or less-than-perfect competition, encouraging firms to invest resources.
In contrast:
- Normal profits (Option A) represent the minimum level of profit needed to keep a firm in business in the long run. Normal profits don’t attract new firms since they imply no extra profit beyond covering costs.
- Cost structure (Option C) refers to how costs are distributed within a firm or industry (fixed vs variable costs), but this alone doesn’t attract firms to an industry.
- Revenue structure (Option D) describes how revenue is generated or allocated, but again, it’s the economic profit that drives firms to enter or expand in an industry.
In summary, economic profits act as a key incentive for firms to enter and expand in growing industries, making option B the best answer.
