The July issue of Qantas Magazine has an article on Akubra hats. The company has a problem: the price of a crucial input into its hats, rabbit skins, has risen by 125 percent in the past three years due to a virus that killed many Aussie rabbits. The rabbit population has been increasing again, but its previous decline caused a much longer-run decrease in the supply of rabbit shooters, who permanently left this occupation for other jobs in this low-unemployment economy.
These two factors—the short-run decrease in supply of rabbits and the long-run decrease in the supply of rabbit shooters—have caused a rise in Akubra’s costs and thus a decrease in supply in the related hat market. This is a nice example of a shock in one market causing a general equilibrium set of adjustments. Good for rabbits in the long run, not so good for bald guys who need hats to protect against the Australian sun!
