```Laffer Curve
July 12, 2012
This is the original graph that
Art Laffer wrote on a napkin.
There is nothing wrong with this graph, but we want to
make it easier to understand, because graphs can become
confusing.

The only thing the Laffer Curve addresses
is the tax rates.

Economics is very complicated because it is
effected by many factors, such as:
Tax Rates
Regulations
Deductions
Exemptions
Stability of Currency
Total Spending
Tax credits.
What is Taxable GDP?
Taxable GDP stands for Gross Domestic
Product that is taxable.
 Taxable Gross Domestic Product is all the
product made and services provided for a
country in a given year that can be taxed.
 In the Laffer Curve we only talk about
taxable GDP.

What is Taxable GDP?
•
Taxable GDP is the money you make that
can be taxed by the government.
•
This does not include income that is
deducted, exempted, or labor you do
yourself.


The Laffer Curve believes that tax payers
thoughts and actions do change with
changing tax rates.

As the Tax Rate increases, the benefit of
the profit is reduced; thus entrepreneurs
are less likely to start, expand, or might

As tax rates increases, the weight or worth
of profits are greatly reduced.
Back to the Basics
A trade of product or labor only happens
when two people agree on a mutual cost
that benefits both people.
 If they both decide that it’s fair to trade
ten chickens for ten stalks of corn, and the
government has a 50% tax rate, then
each person will give ten of their items
away, and only receive five of the other
persons product.

Back to the Basics
The government is taking the other five
products from each person.
 The more the government taxes, the less
 If people stop trading completely, the
governments income would cease to exist.

Now we are going to look at the logic of
the Laffer Curve.
 Its shows us that people’s thoughts and
actions do change with increasing tax
rates.

Lessons Learned
We have to know when to stop taxing.
 As we saw, if the government taxes us too
much, then it is no longer worth working.
 People then start trying to do things on
their own.
 This is not nearly as productive.

Lessons Learned





The higher the rate of welfare, the less
economic activity.
If the government gives us things, we are less
willing to work for it.
The total amount of people in America on
welfare is approximately 15,000,000 people!
\$132 billion are spent on welfare alone each
year (not including food stamps or
unemployment)!
This forces the tax rate higher, thus reducing
GDP.
Lessons Learned
Exemptions and deductions are
counterproductive.
 Exemptions and deductions are when
government makes exceptions on what
GDP is taxed and what is not.
 When government makes exceptions on
too many circumstances, they realize they
aren’t getting enough tax revenue.
 So, they raise tax rates.
 Now, as we learned, they aren’t going to
raise enough tax revenue.

Lessons Learned
If you have 30% taxation rate and you
have a taxable GDP of \$70 the
government collects \$21.
 If you then exempt 50% of the GDP, the
governments income drops to \$10.50.

Lessons Learned
You will never be able to raise rates high
enough to get back to \$21 because the
taxable GDP drops as you raise the rates.
 It is far superior to lower tax rates instead
of using deductions and exceptions.
 Having progressive tax rates are similar to
large deductions.

One low, flat rate with no
exemptions or deductions will
result in a much higher GDP
