Solution to Problem Set 1, Econ 301, Spring 2013
1. We are given that Y = 40, and PA = 100, and so substituting these values into the
equation that determines the quantity demanded gives us
QS = 100 2PS + 0.5(40) + 0.2(100)
or
QS = 140 2PS.
This is the eq

Answer Key to HW 6:
1. Suppose a monopolist producing Q units of output faces the demand curve P = 20
- Q. Its total cost when producing Q units of output is TC = F + Q2, where F is a
fixed cost. The marginal cost is MC = 2Q.
a) For what values of F can a
Practice for Midterm 1
1. Consider the utility function U(x, y) = xy. The marginal utilities are MUx = y/(2x)
and MUy = x/(2y).
