Suppose the cross price elasticity of demand between grapefruit fruit and orange juice is approximately 6. What does this mean?
A 1 percent decrease in the price of grapefruit juice leads to a 6 percent decrease in orange juice consumption.

According to an article by in the American Journal of Public Health by Edward Kaplan and Michael Merson of Yale University School of Medicine, the federal government's current method of allocating HIV-prevention resources is not cost-effective. Instead of allocating resources to states in proportion to reported AIDS cases, resources should flow first to those activities that prevent more infections per dollar and then to less and less effective combinations of programs and populations until funds are exhausted, even if it means that some populations would be left without any prevention services.
