Explanation:

A monopoly is a market structure which is typically characterized by a single-seller who sells a unique product in the market by dominance. This ultimately implies that, it is a market structure wherein the seller has no competitor because he is solely responsible for the sale of unique products without close substitutes. Any individual that deals with the sales of unique products in a monopolistic market is generally referred to as a monopolist.

For example, a public power company is an example of a monopoly because they serve as the only source of power utility provider to the general public in a society.

In a perfect competition, there are many buyers and sellers of homogeneous products, and there is free entry and exit in the market.

This simply means that, in a perfectly competitive market, there are many buyers and sellers (price takers) of homogeneous products (standardized products with substitute) and the market is free (practically open) to all individuals or business entities that are willing to trade all their goods and services.

Generally, a perfectly competitive market is characterized by the following features;

1. Perfect information.

2. No barriers, it is typically free.

3. Equilibrium price and quantity.

4. Many buyers and sellers.

5. Homogeneous products.

Examples of a perfectly competitive market are the Agricultural sector, e-commerce and the foreign exchange market.

Generally, consumer surplus is less in the case of a single-price monopoly than in the case of a perfectly competitive industry.
