Homework Answers
As price of labor drops, firms' cost of production falls and supply increases from the black line to the blue line (because black line is 100 firms, blue also 100 firms and there is no entry of suppliers at this stage)
In the short run, at the fallen price, all firms lose money and incur losses.
In the long run, existing firms do not benefit from price drop since their profits remain the same. (Perfectly competitive markets are characterized by this phenomena of normal profits in the long run)

Consider the competitive market for copper. Assume that, regardless of how many firms are in the industry, every firm in the Industry is identical and faces the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves shown on
6. Short-run supply and long-run equilibrium Consider the competitive market for copper. Assume that, regardless of how many firms are in the industry, every firm in the Industry is identical and faces the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves shown on the following graph. The following diagram shows the market demand for copper. Use the orange points (square symbol) to plot the initial short-run industry supply curve when there are 20 firms in the market. (Hint:...

Consider the competitive market for halogen lamps. The following graph shows the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves for a typical firm in the industry.
Consider the competitive market for halogen lamps. The following graph shows the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves for a typical firm in the industry. For each price in the following table, use the graph to determine the number of lamps this firm would produce in order to maximize its profit. Assume that when the price is exactly equal to the average variable cost, the firm is indifferent between producing zero lamps and the...

price of $5 per pound of shrimp and a quantity of 300 million
pounds per year. Suppose that the Centers for Disease Control (CDC)
announces that a chemical found in shrimp is causing bacterial
infections to spread around the world.The CDC’s announcement will cause consumers to demand shrimp at
every price. In the short run, firms will respond
