Advantages of Perfect Competition

You can see an explanation of the characteristics of a perfectly competitive market in this article. In addition, here are the advantages of a perfectly competitive market:

a. Due to perfect knowledge among market participants, there is no misinformation and product knowledge is shared equally among all market participants.

b. There are no barriers to entering a perfectly competitive market, so existing firms cannot gain the power to monopolize the market.

How Realistic is the Manifestation of Perfectly Competitive Markets in the Real Business World?

Realistically, there are very few markets or industries in the world that are perfectly competitive. For example, how can a company create a homogeneous product given that even the smallest companies engaged in manufacturing or services try to differentiate their products from other companies.

The assumption that producers and consumers act rationally in a perfectly competitive market has been questioned by behavioral economists. A number of studies have shown that decision making by market participants is often irrational.

Decision making can be biased and subjective when consumers and producers are faced with complex situations. This can be an interesting lesson .

While a perfectly competitive market may be labeled unrealistic by some economists, this model still holds true in two respects; First, many primary commodity markets such as coffee and tea represent some of the characteristics of a perfectly competitive market.

Such as the number of individual producers that exist, and their inability to influence market prices. Second, for other markets in manufacturing and services, the perfectly competitive market model is a useful benchmark against which economists and regulators can evaluate the level of competition in real markets.
