Behavior

Factors of Production
The three factors of production are:
1. Land (including all natural resources)
2. Labor (manual, managerial, entrepreneurial)
3. Capital goods (machines, equipment,
buildings)

Factor Prices
Prices of factors of production are:
 Wages (payment for labor, including salaries
and commissions)
 Rent (payment for the use of land)
 Interest (payment for the use of capital goods)
 Profits (payment for entrepreneurship)

Production Functions
A production function is a relationship
between inputs (factors of production) and
outputs (production).

Production Functions
In the table on the next slide, we look at a
simple production function.
We vary the number of workers, or labor
(variable input), and keep the units of
machinery constant (fixed input).

Marginal production is the additional production
per worker. Adding this in the table, we get (see

Production Functions
In the table on the previous slide, marginal
production decreases after the 3rd worker.
Adding a variable input to a fixed input eventually
results in decreasing marginal production.
This is the law of diminishing marginal production.

Production Functions
The next slide shows a production function in
which the number of workers increases by more
than 1.
Note that marginal production is the change in
total production divided by the change in the
number of workers,

Production Functions
Average production is the production per
worker, or total production divided by the
number of workers.
Question:
In the previous table, what is average
production when the number of workers is 10?
Microeconomics

Production Functions
Answer:
Total production = 30, so
average production
= 30 / 10 = 3

Short Run versus Long Run
The short run is the period of
time during which a firm is
unable to change all of its
factors of production
(it has at least one fixed input).
The long run is the period of time during which a
firm can change all of its factors of production.

Production and Costs
A firm’s production and costs are directly related.
Let’s say that a firm employs 10 workers, and 2
units of machinery, and produces 30 products per
week.
Each worker costs $500 per week. Each machine
costs $800.
What are the firm’s total and average costs?
Microeconomics


Production and Costs
The cost of labor is 10 x $500 = $5,000.
The cost of the machinery is 2 x $800 = $1,600.
Total cost is $5,000 + $1,600 = $6,600.
Average cost (cost per product) is $6,600 / 30 =
$220.

Nominal and Real Factor Prices
Nominal prices are the actual values charged by
the factor supplier.
Real prices are adjusted for inflation.
For example, if a bank charges 10% interest on a
loan, and inflation is 6%, then the real interest rate
on the loan is 10% minus 6%, or 4%.
Microeconomics
Unit 4 - Business Production


Factor Prices
In a free market, factor prices are determined by
the demand for and the supply of the factor of
production.
For example, interest rates are determined by the
demand for and the supply of loans.

Interest Rates
In the next diagram, the equilibrium interest rate is
8%.
Microeconomics

Interest Rates
If the demand for loans increases, then the interest
rate increases:

Interest Rates and Present Value
Because of interest, the value of money increases
over time. $1,000 today is not the same as $1,000
one year from today.
The present value of a future sum of money is:
PV = F / (1 + i) n

Interest Rates and Present Value
Example 1
Someone promises to pay you $1,000 one year
from today. How much is it worth to you today?
Assume that the interest rate is 6%.
Answer:
PV = F / (1 + i) n
1
PV = $1,000 / (1 + .06) = $1,000 / 1.06 = $943.40

Interest Rates and Present Value
Example 2
Someone promises to pay you $5,000 five years
from today. How much is it worth to you today?
Assume that the market interest rate is 8%.
Answer:
PV = F / (1 + i) n
5
PV = $5,000 / (1 + .08) = $5,000 / 1.47 =
$3401.36

Interest Rates and Present Value
Example 3
Let’s say that a house
appreciated in value by
4% each year over the
past 80 years. If the house is
worth $500,000 now, what was the value 80 years
ago?

Example 3 answer:

PV = FV / (1 + i)
80
PV 80 years ago = FV (now) / (1 + .04) .
PV = $500,000 / 23.05 = $21,692.

Factor Prices
Another factor price is the wage rate.
The equilibrium wage is determined by the
demand for and the supply of labor.

Factor Prices
Some factor prices are determined by the
government, not by demand and supply.
For example, in the next slide, the market wage is
$7, but a minimum wage of $9 is set by the
government.

 Factor Prices
Advantages of a minimum wage set above the free
market wage are:
 More income for the minimum wage earners
that are able to maintain their job.
 More incentive for people to work.
 Possibly greater job satisfaction and lower job
turnover.
Microeconomics
Unit 4 - Business Production
 Factor Prices Behavior
Disadvantages of a minimum wage set
above the market wage:
 Decrease
in the quantity demanded for labor.
 Higher production costs and lower profits.
 Higher prices.
 Less money for benefits and training.
 Decrease in exports due to higher prices.

 Factor Prices
Government-set prices that are different from the
market price may have social benefits for some
groups, but lead to economic inefficiencies
(surpluses, shortages, higher prices, unemployment).

Factor Prices
A minimum wage raises the
nominal wage,
but not the real wage.
Question:
How can we achieve higher real
wages without government
intervention?

Factor Prices
Answer:
An economic system that
rewards hard work and innovation.
Question:
What kind of economic system rewards work and
innovation?
Microeconomics


Factor Prices
Answer:
An economic system in which
a government provides essential services
(infrastructure, a legal system, defense, and
protection of private property), and that has
relatively low taxes and limited regulations.
This encourages production and innovation.
