The model of competitive market relies on these three core assumptions: 1. There must be many buyers and sellers-a few players can't dominate the market.
2. Firms must produce an identical product--buyers must regard all seller's products as equivalent.
3. Firms and resources must be fully mobile, allowing for free entry into and ext from the industry.
The first two conditions imply that all consumers and firms are price takers. While the third is not necessarily for price-taking behavior, assume for this problem that a market cannon maintain competition in the long run without free entry.
Identify whether or not each of the following scenarios describes a competitive market, along with the correct explanation of why or why not.
a. Several stores in the mall sell hooded sweatshirts. Each store's sweatshirts reflect the style of that particular store. Additionally, some stores use higher-quality cotton than others, which is reflected in the apparel's prices.
b. In a small town, there are two providers of broadband internet access: a cable company and the phone company. The internet access offered by both providers is of the same speed.
c. There are hundreds of high schools students in need of algebra tutoring services in Dallas. Dozens of companies offer tutoring services, and the parents who seek out tutors view the quality of the tutoring at the different companies to be largely the same.
d. The government has granted a patent to a pharmaceutical company for an experimental AIDS drug. That company is the only firm permitted to sell the drug.
i. Yes, meets all assumptions.
ii. No, no free entry
iii. No, not many sellers
iv. No, not an identical product.
