American restaurants receive their supply of baby back-ribs from American farms and from farms in Denmark. In the figures above, the left diagram shows the perfectly competitive market for baby back ribs in the United States. The right figure shows the situation at Premium Standard Farm in Kansas, one of the many U.S. farms supplying these ribs.
Now assume that the United States imposes a ban on European meat in response to the foot-and-mouth disease that has infected livestock in Europe. (Which the United States did a few years ago.) In particular, suppose that the U.S. ban decreases the supply by 40 tons a year. Using the figure on the left, show the impact of this ban on the baby back rib market. Using the figure on the right, show the impact on Premium Standard Farm in Kansas.
