Answer to Question 1

It may be that people who are only willing to pay for the lower-priced generic are also the same people that are willing to hunt for it in the store. People that are less sensitive to price may simply purchase the higher-priced name brand products that are at eye level and not bother with taking the time to look for the lower-priced and hard-to-find generics.

Answer to Question 2

The factor substitution effect is the tendency of firms to substitute away from a factor whose price has risen and toward a factor whose price has fallen.
