Consider the perfectly competitive market for ceiling halogen lamps. The graph below shows the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves for a typical firm in the industry. Use the graph below to plot the short-run individual supply curve for the firm. Use the purple line segment (diamond symbols) to plot the portion of the supply curve that corresponds to prices where there is no output. Remember to start plotting from the origin. Use the orange points (square symbols) to plot the portion of the supply curve that corresponds to prices where there is positive output. Line segments will automatically connect the points. Remember to plot from left to right.
