  1. There are numerous buyers and sellers, none of whom has a substantial share of the market.
  2. All buyers and sellers can freely and immediately enter or leave the market.
  3. Every buyer and seller has full and perfect knowledge of what every other buyer and seller is doing, including knowledge of prices, quantities, and quality of all goods being bought and sold.
  4. The goods being sold in the market are so similar to each other that no one cares from which each buys or sells.
