3. Using your knowledge of marginal revenue product, explain the following:

a. A famous tennis star is paid $100,000 for appearing in a 30-second television

commercial. The actor who plays his doubles partner is paid $500.

Marginal revenue product of labor, MRPL, is equal to marginal revenue from an

incremental unit of output multiplied by the marginal product from an incremental

unit of labor, or in other words, the extra revenue generated by having the tennis star

appear in the ad. The famous tennis star is able to help increase revenues far more

than the actor, so he is paid much more than the actor. The wage of the actor is

determined by the supply and demand of actors willing to play tennis with tennis stars.
