Why might you underestimate the increase in market quantity demanded when you lower your price? You may not take into account potential new customers attracted by the lower price.

A price reduction increases the quantity demanded for individuals but not for the entire market.

When a popular comedian announces a tour, tickets often sell out quickly. However, it is quite common for the tour coordinator to later announce additional shows in the form of matinees and late-evening performances.

People who purchased a ticket consider the comedian's show to be an inferior good. The tour coordinator knows that the price elasticity of demand for tickets is perfectly elastic. Attendees to the shows consider many other comedians' performances to be close substitutes.
