Professor P has hired a teaching assistant, Mr A. Professor P cares about how many hours that Mr. A teaches and about how much she has to pay him. Professor P wants to maximize her payoff function, x - s, where x is the number of hours taught by Mr. A and s is the total wages she pays him. If
Mr. A teaches for x hours and is paid s, his utility is s - c(x) where c(x)= x2/2. Mr. A's reservation utility
is zero.
(a) If Professor P chooses x and s to maximize her utility subject to the constraint that Mr. A is willing to
work for her, how much teaching will Mr. A be doing?
- (b)How much will Professor P have to pay Mr. A to get him to accept this amount of teaching?
- (c)Suppose that Professor P uses a scheme of the following kind to get Mr. A to work for her. Professor P sets a wage schedule of the form s(x) = ax+b and lets Mr. A choose the number of hours that he wants to work. What values of a and b should Professor P choose so as to maximize her payoff function? Could Professor P achieve a higher payoff if she were able to use a wage schedule of more general functional form?
