In 2007, the average
a. Use graphs to illustrate that this increase in the price of shipping is due to an increase in demand, particularly from the growing Chinese and Indian economies, and a fixed number of ships in the short run. In the long run, after an increase in the number of ships, shipping prices should drop.
