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?
