Suppose that the tuna industry is in long-run equilibrium at a price of $5 per can of tuna and a quantity of 250 million cans per year. Suppose that the Centers for Disease Control (CDC) announces that a chemical found in tuna helps prevent many viral infections from spreading. The CDC's announcement will cause consumers to demand tuna at every price. In the short run, firms will respond by Shift the demand curve, the supply curve, or both on the following diagram to illustrate these short-run effects of the CDC's announcement. 10 9 Supply Demand 8 7 Supply Demand 2 1 50 100 150 200 250 300 350 400 450 500 QUANTITY (Millions of cans) In the long run, some firms will respond by until PRICE (Dollars per can)

2. A faculty member sells Gatorade at UNC Charlotte football games. He finds that if he raises his selling price by $1, he sells 6 less bottles each week. He turns over the operation to a Managerial Economics student for a week. The goal is to maximize revenue since the faculty member has a vast supply of Gatorade, and any unsold bottles can be sold in future weeks. The student takes over the operation for a week. She says she sold at the revenue-maximizing price of $4 per bottle. How many units sold? Show your work/thought process:
The following graph shows the market for annual tortilla chip consumption, which is initially in long-run equilibrium at point D. After the change in tastes and the rightward shift in demand, the market moves to point in the short run and then to point in the long run. On the following graph, use the purple line (diamond symbol) to plot the long-run market supply curve for tortilla chips, making sure that it goes through two of the points A, B, C, or D.

Due to the government's program for developing alternative fuels, the demand for ethanol has increased dramatically. Ethanol is made from corn. Corn is also used as a feed for hogs. Simultaneously, many more cases of mad cow disease have been discovered in the United States. Assume that pork and beef are substitutes in consumption, but not in production. As a result of these two changes, what will happen to the price and output of pork? Briefly explain.
Consider the market for Caribbean cruises. In the wake of the COVID-19 pandemic, the cruise companies take the following actions. First, they implement testing and tracing programs to limit the potential of COVID outbreaks on ships to occur and to spread. Second, they engage in widespread advertisement of their new and state of the art safety precautions. Using a generic model of supply and demand, show and describe how you would expect these initiatives would affect the market for cruises. Be sure to explain why which curves are shifting, and discuss changes to market equilibrium.

In 2014, the Seattle Seahawks won the Super Bowl. Draw a supply and demand graph for Seahawk tickets in the following season to show the impact of the Super Bowl win. (It would be the same graph for Seahawk t-shirts, hotdogs at the game and beer.)

Supply and Demand- End of Chapter Problem The market for many goods changes in predictable ways, according to the time of year, in response to events such as holidays, the vacation times, seasonal changes in production, and so on. For the following case, shift the supply and demand curves graph below and move the equilibrium point to its new position. Note that supply and demand may shift simultaneously. Case: The price of a Christmas tree is lower after Christmas than before, but fewer trees are sold. Market for Christmas Trees Page 256 Market for Christmas Trees E Quantity of trees Price per tree
