7. The long-run supply curve in different cost industries The following graph shows the market for breakfast bar. Initially, the market is in a long-run equilibrium. Suppose that a change in tastes resulted in a leftward shift in demand. On the following graph, shift the demand or supply curve to reflect this change in tastes. Then use the grey point (star symbol) to indicate the new short-run equilibrium 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. PRICE (Dollars per bar) Short-run Spply QUANTITY (Thousands of t In the short run, firms will 10 Demand 101 Short-nun Supply * Short-nun Equilibrium Long-nun Equilibrium 181 Long-un Supply Ⓒ In the long run, the supply curve will On the previous graph, show the shift in the supply curve and then use the purple point (dumond symbol) to indicate the resulting new long run equilibrium Comparing the two long-run equilibria on the graph, you can see that the breakfast bar market is an example of On the previous graph, use the green line (diamond symbols) to plot the long-run market supply curve for breakfast bars

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 bad for your health. The Surgeon General's report will cause consumers to demand 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. Supply X Demand 400 600 800 QUANTITY (Millions of cans) 0 0 In the long run, some firms will respond by 5 0 200 0 200 Demand 1000 Shift the supply curve, the demand curve, or both on the following diagram to Illustrate both the short-run effects of the Surgeon General's announcement and the new long-run equilibrium after firms…

Suppose that the jackfruit industry is initially operating in long-run equilibrium at a price level of $5 per pound of jackfruit and quantity of 75 million pounds per year. Suppose a leading foodie video blogger raises awareness for a scholarly article that links jackfruit consumption to premature hair loss and unhealthy skin. The viral video is expected to cause consumers to demand Shift the demand curve, the supply curve, or both on the following graph to illustrate these short-run effects of the viral video.
