Perfect competition is the simplest market structure, where the market is assumed to be in equilibrium and that all sellers sell the same product at the same price. The four conditions for perfect competition are:
1. There are many buyers and sellers in the market so that no one individual or seller can influence the price of the products, goods, and services.
2. Identical products are offered by the sellers
3. Both the buyers and the sellers are well-informed about the products and want to maximize profit.
4. Entry and exit to and from the market can be done freely by the sellers and buyers.
