Economics demand is extremely inelastic
Part 1: From the book, Answer discussion questions 5.4 & 5.5 p 99, as follows
Question 1: No. 5.4. from the book. Using figure 5.3 as a basis, construct a set of
four figures to show the effect of an increase in the demand for tanker service
on the market price when:
(a) demand is extremely inelastic,
(b) demand is extremely elastic,
(c) supply is extremely inelastic, and
(d) supply is extremely elastic.
Question 2: No. 5.5 from the book. Manufacturers of cardboard cartons and other
packaging use inputs of wood pulp and wastepaper. An issue in environmental
policy is the effectiveness of price incentives in encouraging households and
businesses to recycle wastepaper. The price elasticity of the demand for
wastepaper has been estimated to be -0.07, while the price elasticity of the supply
has been estimated to be 0. (Source: John A. Edgren and Kemper W. Moreland,
“An Econometric Analysis of Paper and Wastepaper Markets”, Resources and
Energy, Vol. 11, 1989, pp. 299-319.)
(a) Consider a government policy that reduces the price of wastepaper to
manufacturers by 5%. How will this affect the quantity demanded?
(b) Consider a government policy that increases the price of wastepaper to sellers
by 5%. How will this affect the quantity supplied?
(c) Are price incentives an effective way of increasing the recycling of
wastepaper?

Question 5:
Mars Inc. produces 100,000 boxes of Snickers bars which sell for $4 a box. If variable costs are $3
per box, and it has $150,000 fixed operating costs, in the short run. A) Is the firm losing or making
money? B) if the firm is losing money, should the firm continue or shut down its operations?
