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 profit-maximizing quantity. Also, indicate whether the firm will produce, shut down, or be indifferent between the two in the short run. Lastly, determine whether it will make a profit, suffer a loss, or break even at each price.

If there were 60 firms in this market, the short-run equilibrium price of titanium would be $________ per kilogram. At that price, firms in this industry would (earn a positive profit, shut down, earn zero profit, operate at a loss). Therefore, in the long run, firms would ( enter, exit, neither enter nor exit) the titanium market. Because you know that perfectly competitive firms earn (positive, zero, negative) economic profit in the long run, you know the long-run equilibrium price must be $_______ per kilogram. From the graph, you can see that this means there will be (20, 40, 60) firms operating in the titanium industry in long-run equilibrium.
If there were 10 firms in this market, the short-run equilibrium price of steel would be $______per ton. At that price, firms in this industry would ______(shut down/operate at a loss/ earn a positive profit/ earn zero profit). Therefore, in the long run, firms would__________(enter/ exit/ neither enter nor exit) the steel market. Because you know that competitive firms earn______(zero/ negative/ positive) economic profit in the long run, you know the long-run equilibrium price must be $_____per ton. From the graph, you can see that this means there will be_____(10/20/30) firms operating in the steel industry in long-run equilibrium.
The diagram to the right shows the long-run equilibrium for a competitive market for three different levels of demand (Do, D₁, and D₂). Assume that firms earn a normal level of profits at each market equilibrium. Illustrate the long-run industry supply curve. Using the line drawing tool, draw the long-run industry supply curve.

Lesson 5.4 - Industry Adjustments to Increases in Demand 1. In a/an industry, an increase in demand will result in a new equilibrium price equal to the original equilibrium price (before demand increased). This results in a long-run supply curve that is 2. In a/an industry, an increase in demand will result in a new equilibrium price higher than the original equilibrium price (before demand increased). This results in a long-run supply curve that is sloping. 3. In a/an. industry, an increase in demand will result in a new equilibrium price lower than the original equilibrium price (before demand increased). This results in a long-run supply curve that is sloping.
