Joy waits into a long line at her local bookstore therefore she can be between the first to buy and read a newly-printed hardback copy of the newest Harry Potter adventure. And Lindsay waits till a lower priced paperback edition is printed just before buying any Potter book. This is clear here that: (1) Joy has more income than Lindsay. (2) Lindsay derives less utility than Joy does by reading concerning Harry’s adventures. (3) Lindsay’s price elasticity of demand is less than Joy’s is for these books. (4) Joy probably wants glasses to read the smaller kind used to print paperbacks. (5) Lindsay is not as avid a Harry Potter fan like Joy is.
Can anybody suggest me the proper explanation for given problem regarding Economics generally?
