Suppose that the perfectly competitive tuna industry is in long-run equilibrium at a price of $3 per can of tuna and a quantity of 600 million cans per year. Suppose the Surgeon General issues a report saying that eating tuna is good for your health. The Surgeon General's report will cause consumers to demand v tuna at every price. In the short run, firms will respond by Shift the supply curve, the demand curve, or both on the following diagram to illustrate these short-run effects of the Surgeon General's announcement. Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back to its original position, just drag it a little farther.

7. Short-run and long-run effects of a shift in demand
Suppose that the perfectly competitive tuna industry is in long-run equilibrium at a price of $3 per can of tuna and a quantity of 600 million cans per
year. Suppose the Surgeon General issues a report saying that eating tuna is good for your health.
The Surgeon General's report will cause consumers to demand
tuna at every price. In the short run, firms will respond by
Shift the supply curve, the demand curve, or both on the following diagram to illustrate these short-run effects of the Surgeon General's
announcement.
Note: Select and drag one or both of the curves to the desired position. Curves will snap into position, so if you try to move a curve and it snaps back
