Assume that a perfectly competitive hand sanitiser market is in long-run equilibrium. The price of hand sanitisers is observed to increase during the COVID 19 pandemic, and then it returns back to its normal price after the pandemic. Use the diagram below to discuss this market before, during and after the pandemic. Include in your discussion the profit levels in each case.

2.   Assume the market for soybeans is perfectly competitive and in long-run equilibrium, and Norma’s Soybeans is a small farm in the market. Draw correctly labeled side-by-side graphs of both the market for soybeans and the firm, labeling the market equilibrium Pm and Qm and Norma’s Soybean equilibrium Pf and qf. Is Norma’s Soybeans earning economic profits, economic losses, or a normal profit? Now assume that in the soybean market there is a huge drought that ruins the soybean harvest...

1) Imagine a perfectly competitive market that is currently in a long-run equilibrium with price=$10, individual firm quantity set at 10 units, and 100 active firms. Scientific discoveries about the health benefits of this good lead to a permanent increase in demand for this good (but no changes in firm costs). Once the market is able to fully adjust, then compared to the original long-run equilibrium, the new long-run equilibrium will have A) a lower price and fewer active firms...

Suppose that a perfectly competitive industry is in long-run equilibrium. Then the price of a complementary good decreases. Use two graphs, one for the firm, and one for the industry (and words) to explain what will happen in the short run, and then the long run, to: a. The market demand curve? b. The market supply curve? c. Market price? d. Market output? e. Representative firm output? f. Representative firm profit?

Assume that a perfectly competitive, constant cost industry is in a long run equilibrium with 60 firms. Each firm is producing 90 units of output which it sells at the price of $41 per unit; out of this amount each firm is paying $3 tax per unit of the output. The government decides to decrease the tax, so the firms will be paying $1 tax per unit. a) Explain what would happen in the short run to the equilibrium price...
