7. The long-run supply curve indifferent 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 rightward 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.

10 The industry in the figure given below on the left consists of many firms with identical cost structures, and the industry experiences constant returns to scale. a. Draw the short-run market supply curve up to 4,000 units of output. Instructions: Use the tool provided (SRMSC) to draw the short-run market supply curve. Plot three points total. b. Draw the long-run market supply curve from zero to 4,000 units of output. Instructions: Use the tool provided (LRMSC) tool to draw the long-run market supply curve. Plot only the endpoints across the entire output range (0 to 4,000).

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.

Suppose the cost of renting a snowy bus were to fall from $30 per hour to $20 per hour. What do you expect would happen in the short-run (stage 1 equilibrium) to (a) the number of cones produced by each snowy bus; (b) total production of cones in the market, and (c) economic profits of snowy bus businesses? Briefly explain (you don't need to do any calculations, just explain inwords).

Use the orange points (square symbol) to plot the short-run industry supply curve for the wheat industry. Specifically, place an orange point at the lowest point of the supply curve and another orange point at the highest point of the supply curve. (Hint: You can disregard the portion of the supply curve that corresponds to prices where there is no output, since this is the industry supply curve. Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.) 2.

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.
