Advantages of Perfect Competition
1. They allocate resources in the most efficient way- both productively (P=MC) and allocatively efficient (P> MC) in the long run.

3. Only normal profits made just cover their opportunity cost
4. Maximum consumer surplus and economic welfare
Disadvantages of Perfect Competition
1. No Scope for economies of scale because of the high number of firms in there
2. Undifferentiated products- all homogeneous. Important in industries like clothes and cars
3. Lack of supernormal profits may mean the investment of Research and 4. Development(R&D) is unlikely. Important for industries like pharmaceuticals.
5. With perfect knowledge there is no incentive to develop new technology because of the ability to share information.- FREE RIDERS of info.
How realistic is the Perfect Competition Model?
In reality it is more about theory rather than pratical. This the extreme spectrum of market structure.
However it is said that being perfectly competition is the position that firms should be or similarly in due to the efficiencies it can bring to the economy. Scarce resources would be allocated well.
It is said it doesn’t have to be perfectly competition but in real life competition should have similar characteristics like:
• Many firms in the market
• Few barriers of entry and exit
• Incentives to cut costs
• Profits will be lower compared in markets than monopoly power
