SUPPLY DEFINED
The amount of a good or service a firm wants to
sell, and is able to sell per unit of time.

3. Supply slide 3
The DEPENDENT variable is the amount supplied.
The INDEPENDENT variables are:
the good’s own price
the prices of inputs used in its production
the technology of production
taxes and subsidies
THE “STANDARD” MODEL OF
SUPPLY
AN IMPORTANT POINT
When drawing a supply curve notice that the axes are
reversed from the usual convention of putting the
dependent (y) variable on the vertical axis, and the
independent (x) variable on the horizontal axis.

THE SUPPLY CURVE
The supply curve for any good shows the
quantity supplied at each price, holding
constant all other determinants of supply.
The DEPENDENT variable is the quantity supplied.
The INDEPENDENT variable is the good’s own
price.

5. Supply slide 5
THE LAW OF SUPPLY
The Law of Supply says that an increase in a
good’s own price will result in an increase in
the amount supplied, holding constant all the
other determinants of supply.
The Law of Supply says that supply curves are
positively sloped.

HYPOTHESES ABOUT HOW
CHANGES IN EACH OF THE
INDEPENDENT VARIABLES
AFFECTS THE AMOUNT
SUPPLIED

8. Change in technology
Other factors affecting supply
The question here is how to show the effects of changes in input
prices, technology, and taxes.
The answer, of course, is that changes in input prices, technology, or
taxes cause the supply curve to shift.
An improvement in technology makes it possible to produce a
level of output with fewer inputs than before.
Because this lowers the cost of production, profits rise, and firms
will try to supply more.

13. Supply summary
Supply
slide
15
Supply is a function of own price, input prices,
and technology.
The supply curve shows supply as a function of
own price, all else constant.
Changes in a good’s own price show up as
movements along a supply curve.
Changes in input prices, technology, or taxes
show up as shifts in the supply curve.
