
What is economic profit in a perfect free
market economy?


Returns above and beyond a fair return to capital,
labor and entrepreneurial skills
Zero
Markets cannot not drive rent to zero

Three Types of Profit: 2

Economic Profit = total revenue – explicit
costs – implicit costs (opportunity cost of the
resources supplied by the firm’s owners)


E.g. Take farmers total revenue, subtract total
costs, including money farmer could have made
working elsewhere, money he could have made
renting his land to someone else, etc.
Payments to factors of production (explicit
and implicit)



Payment to labor (human capital) = wage
to land (natural capital) = rent (unearned income)
to capitalists (finance and machinery/built capital)
= interest

Three Types of Profit: 3

Normal Profit = accounting profit –
economic profit= fair payment to implicit
costs

i.e. normal profit occurs when all factors
of production, owned and unowned,
earn their expected returns

E.g. Farmer earns as much farming as he
would working elsewhere and renting his
land to a neighbor.

Two Functions of Price: 1

The rationing function of price
To distribute scarce goods to those
consumers who value them most highly
 BUT as economists determine value, you
can only value something if you have
money.

 Amerindians
in the Amazon do not value the
forest
 Poor people do not value life saving medicine,
e.g. eflornithine

There is no role for ethical, moral or social
values

Two Functions of Price

The allocative function of price
To direct resources away from
overcrowded markets and toward markets
that are underserved
 BUT, from the economists perspective,
markets in life saving medicines for poor
people are overcrowded, while markets for
facial hair loss formulas for rich people are
underserved.
 Allocative function eliminate economic
profit, but not rent

The Invisible Hand Theory

Profits and Losses Would Ensure

That supplies within a market would be distributed
efficiently (rationing function)
 Outputs
will go to those consumers who value them the
most (i.e. who can pay the most)

Resources would be allocated across markets to
produce the most efficient possible mix of goods
and services (allocative function)
 Inputs
will go to those producers who can pay the most
for them (i.e. who can create the highest valued products
from them)

Markets balance possibility with desirability

Responses to Profits and Losses

Markets with firms earning economic
profits will attract resources.

Markets where firms are experiencing
economic losses tend to lose resources.

Shifts in demand will raise or lower
prices, hence profits, leading to entry or
exit of firms, returning prices to their
‘fair’ level

The Invisible Hand Theory

In the long-run, in a competitive market, all
firms will tend to earn zero economic profits.



Consumer gets the good as cheaply as possible
But remember, normal profits cover all the costs of
production
Zero economic profits are the consequence of
price movements caused by the entry and exit of
firms trying to maximize economic profits.

Two Attractive Features

The market outcome is efficient in the
long run.


P = MC= min ATC
The market is fair.
The price the buyers pay is no higher than
the cost incurred by sellers.
 The cost includes a normal profit.
 Normal profits include payments to all
factors of production, including a CEO
making 100 million a year.

Free Entry and Exit

Free entry and exit must exist for the
allocative function of price to operate



Barriers to entry can be caused by legal
constraints and unique market characteristics
Barrier to entry exists when only fixed quantity of
resource is available

Versus Economic Profit
Economic Rent

That part of a payment for a factor of
production that exceeds the owner’s
reservation price
 Think

about land.
Market forces will not push economic rent
to zero because inputs cannot be
replicated easily
 But

Economic Rent
Versus Economic Profit

Textbook example: ignores injustice of
rent

Assume
A community with 100 restaurants
 99 restaurants employ chefs with normal
ability for $30,000/yr (the same amount
they could earn elsewhere)
 The 100th restaurant employs a talented
chef and customers are willing to pay 50%
more for their meals



Economic Rent
Versus Economic Profit
Assume
TR at the each of the 99 restaurants is
$300,000, which yields a normal profit
 TR at the 100th restaurant is $450,000
(50% more)


How much will the good chef earn?

Reservation price = $30,000 = opportunity
cost

output of grain without changing the market
price.

Observations
• If P = $3 & Q = 12 MR < MC
and output should be
reduced
• Profits are maximized at 8

Marginal cost
Deadweight loss
• Because MR < P, the monopoly
produces less than the socially
optimal amount
• The deadweight loss of the
monopoly to society =
