Answer:
The answer is: Supply curves must reflect all costs of production, and demand curves must reflect consumers´ full willingness to pay.
Step-by-step explanation:
The characteristics of a competitive market are:
- Many buyers and sellers
- Companies make a similar product.
- Both buyers and sellers have access to perfect information about price.
- No transaction costs.
- No barriers to entry into or exit from the market.
Theoretically if all of the above conditions occur, profit maximizing companies will combine with utility maximizing consumers, and markets will tend to produce efficient outcomes.
