Exercise 2
1.) Suppose that the monthly demand for Alaska Club memberships is QD = 10000 – 10P.
a.) Using the formula for elasticity we have described in class, suppose that the initial
price is \$400 dollars, calculate the price elasticity of demand between a price of \$500 and
\$400 (P in the equation above is equal to price). Explain the meaning of your answer
using the concept of elasticity.
b.) Suppose that the prevailing price is \$400. Would you recommend an increase in the
price to \$500, why or why not? Explain using the concept of elasticity. If not, describe
the conditions under which you could make such a recommendation.
c.) Calculate the total revenue first from the sale of memberships at a price of \$400 and
then at a price of \$500. Do you reach a different conclusion regarding the effect of the
increase in price?
d.) Under what condition would you unambiguously recommend a firm to increase their
price?
