Suppose there are ten people playing cards in a room. One of them wants to smoke a
cigar; nine of them dislike the smell of cigar smoke. The smoker values the privilege of
smoking at $5, and each of the other nine occupants of the room would be willing to
pay fifty cents for clean air in the room. The rules governing use of the room state that
smoking is not allowed unless everyone agrees to allow smoking.

no opportunity to negotiate would:
A. decrease total economic surplus.
B. increase total economic surplus.
C. leave total economic surplus unchanged, but redistribute benefits.
D. efficiently solve the externality problem.
