(3) Evaluating Profitability Using the Average/Marginal Approach
Perfect Competition, Total Profits, Average Profits, Profit-Volume Analysis
This shows how a graph of revenues and costs can be used to conduct profit-volume analysis. The average/marginal approach is used. The profit maximizing output level is identified, and the associated total revenue and total cost measures are shown. This leads to an evaluation of profitability at the profit maximizing output level. Three outcomes are reviewed: 1) the firm making money, 2) the firm losing money, and 3) the firm breaking even by earning zero profits.
