An article in the Wall Street Journal in early 2001 noted two developments in the
market for laser eye surgery. The first development concerned side effects from the
surgery, including blurred vision. The second development was that the companies

laser eye surgeries, these two developments

quantity and an increase in the equilibrium price of laser eye surgeries.

equilibrium quantity and the equilibrium price of laser eye surgeries.
