Firms are Restrained from raising its price because consumers will find another competitor in the market with lower prices
Many Firms
Many buyers and firms exist to create the larger market
Many Identical Products
Relative Ease in Market Entry
Meaning there are no barriers or walls preventing anyone from entering the market
So How Do Firms Maximize Profit?
Figuring out how much of a
product should be
produced
Profit=TR-TC
To maximize profits the firm
should produce the quantity
where the difference
between total revenue and
total cost is as large as
possible
MR=(ΔTR)/(ΔQ)
MR=(Change in total revenue)/(Change
in Quantity)
Total Profit= (p-ATC) x Q
P>ATC, firm has
profit
P=ATC,
breaks even
P<ATC, firm
faces loses
What if the firm is
experiencing loses?
Long-run decision
Exit the Market
Short-run decision
Temporarily stop production
If, Total Revenue < Variable Cost
Face Sunk Cost
A fixed cost that is
unavoidable and
can't be recovered
Continue to Produce
If, Total Revenue >= Variable Cost
Short-run supply curve
Where MC and AVC
meet is the
shutdown point
MC is the
supply curve
for firms in
SR
P is the minimum price
where the firm can
continue to produce
Horizontal Demand Curve
Because firms are selling the same
products they can sell as much as they
wants at that times current market
price but won't be able to if the price is
raised
No matter the quantity sold by a
firm, no effect on the market
price will take place
