Suppose that the shrimp industry is in long-run equilibrium at a price of $5 per pound of shrimp and a quantity of 150 million pounds per year. Suppose the Surgeon General issues a report saying that eating shrimp is bad for your health.
The Surgeon General’s report will cause consumers to demand shrimp at every price. In the short run, firms will respond by .
Shift the demand curve, the supply curve, or both on the following graph to illustrate these short-run effects of the Surgeon General’s report.
In the long run, some firms will respond by until .
Shift the demand curve, the supply curve, or both on the following graph to illustrate both the short-run effects of the Surgeon General’s report and the new long-run equilibrium after firms and consumers finish adjusting to the news.
The new equilibrium price and quantity suggest that the shape of the long-run supply curve in this industry is in the long run.
Now suppose that an FDA report announces that coffee is harmful to cardiovascular health. Starting from the diagrams show and discuss with your group how the market will adjust towards a short-run equilibrium and then return to a long-run equilibrium. What happen to the market price and quantity in the short-run? What happens to individual firm output and the number of firms in the short-run? What is the profit in the short-run? What happen to the market price and quantity in the long-run? What happens to individual firm output and the number of firms in the long-run? What is the profit in the long-run?

The overall demand for wheat is made up of two components – domestic demand and foreign demand. Due to tariff disputes with the U.S., the European Union (EU) has urged its member nations to reduce their demand for U.S. agricultural products (including wheat). As a result, the foreign demand for U.S. wheat has declined by 20% this year. Using diagrams for a representative farm (i.e., wheat producer) and the market for wheat, analyze the impact of this decrease in foreign demand on the farm’s output and profit (loss) in the short-run and long run. Assume that the farm was in long-run equilibrium (i.e., earning zero economic profits) before the decrease in the foreign demand for wheat. Also, assume that the farm was facing a U-shaped AC curve and the typical upward-sloping MC curve.
