Step-by-step explanation:
The profit pool refers to the total profits earned in an industry at all points along the value chain. This concept is significant because it reflects the overall earnings generated by companies in various stages of producing and selling a product or service. Understanding and analyzing the profit pool is crucial for companies as they decide where to compete within the industry and how to strategize for their growth. When employees directly benefit from the success of a business, typically through profit-sharing arrangements, there tends to be an increase in productivity, as they have a vested interest in the company's performance.
Calculating average profit can be done by subtracting average cost from price, which reflects the firm's profit margin. If a company's market price is above its average cost, it will have a positive average profit, leading to a positive total profit. Conversely, if the price is below the average cost, profits will be negative. The idea of a profit pool is integral in a competitive market; profitable companies often use their earnings as a means to expand and grow, which can include opening new factories or entering new markets. This phenomenon is called entry and it occurs when new firms are attracted to the industry by the potential for profits.
