DO THESE 2 MARKET STRUCTURES HAVE A GOOD EXPLAINATION? WHY OR WHY NOT?

1. Oligopoly:

Ex. Nike shoes (good). In the world of athletic footwear, Nike holds the most power among the various athletic shoe brands, which makes it difficult for new brands to break into that market.

2. Monoplostic:

Ex. Clothing stores (good). There are many different types of stores that sell different types of clothes, meaning that there are a large number of buyers and sellers. Breaking into this market would not be as difficult as breaking into an oligopoly, due to the constant influx of new sellers and buyers.
