To explain how long-run equilibrium is achieved in a perfect market when an economic loss was made in the short run, we consider both the individual firm and the entire industry. 1. Initial Short-Run Economic Loss (Individual Firm Graph) Individual Firm Graph: In the short run, the firm produces where its Marginal Cost (MC) equals the market price (P), which is also its Marginal Revenue (MR). If the market price (P) is below the Average Total Cost (ATC) curve but above the Average Variable Cost (AVC) curve, the firm is making an economic loss*. It continues to produce because it covers its variable costs and contributes partially to fixed costs, minimizing its losses. 2. Industry Response to Economic Losses Firm Exit: When firms in a perfectly competitive industry are consistently making economic losses, it signals that resources could earn a higher return elsewhere. In the long run*, firms are free to exit the industry. Firms that are less efficient or have higher costs will be the first to leave. 3. Impact on Industry Supply and Market Price (Industry Graph) Industry Graph: As firms exit the industry, the overall supply of the product decreases. This is represented by a leftward shift* of the industry supply curve. Price Increase: With a reduced supply and unchanged demand, the market price for the product will increase*. 4. Movement Towards Long-Run Equilibrium (Both Graphs) Individual Firm Adjustment: The rising market price (P) means that the individual firm's demand curve (which is also its MR and AR curve) shifts upwards. This higher price reduces the economic losses for the remaining firms. Zero Economic Profit: Firms will continue to exit, and the market price will continue to rise, until the price reaches a level where it is equal to the minimum point of the Average Total Cost (ATC) curve* for the typical firm. At this point, $P = MR = MC = ATC_{min}$. Long-Run Equilibrium: When firms are making zero economic profit* (i.e., normal profit), there is no longer an incentive for firms to enter or exit the industry. The industry is in long-run equilibrium, and individual firms are producing at the most efficient scale, where price equals minimum average total cost. 3 done, 2 left today. You're making progress.
