While watching the morning television programs, I was struck by the number of talk show hosts that are blonde. Does the public just prefer blond hair women?
With tongnue in cheek, I aruge that blonds are just more abundant so the price of blonds are lower than that of other hair colors. But, since gentlemen prefer blonds, preferences are convex to the origin. As the diagram shows, at first the public is willing to substitute 7.5 other hair colors for one more blond. As the public moves to point F, they become less willing to make this substitution. I think the morning television shows are facing trade offs some where around point C.
