jackets) by . Solve the UMP and derive expressions for and in terms of the parameters
and (i.e. don’t
use numbers for ).
(c) Use your answers in parts (a) and (b) to deduce the parameters and in the utility function. Does this consumer
have monotonic preferences over D & H jackets (good 1)? Show all calculations and state any assumptions.
(d) For what price of D & H jackets will a NYC customer maximize or minimize savings? Prove whether savings are
maximized or minimized. Show all calculations and state any assumptions. Hint: Use the expression for from part (b).
(e) Suppose in April 2010, D & H sells jackets in NYC through a two part tariff where each customer pays an access fee
for the right to buy jackets and a “usage” price for each jacket. Use the individual demand curve in part (a) and
calculate the optimal and (answers with decimal places are OK). Graph your solution below. Hints: Allow for the

. [Do two part tariff pricing in this part only].
(f) Now suppose that in April 2010 D & H sells jackets in NYC through 1st degree price discrimination. Use the individual
demand curve in part (a) to calculate the optimal prices and number of jackets (answers with decimal places are OK).
Graph your solution below. [Do 1st degree price discrimination in this part only]. (g) [This part assumes uniform prices] Suppose that in April 2010,
( ) ( . Consider a typical NYC consumer with the

Using values for and from part (c), solve the UMP for the optimal
and (any) Lagrange multipliers given that
. Calculate the marginal utility of relaxing the savings limit constraint. Show all calculations and state any
assumptions. . Question 17.6 6
