Milton Friedman on taxes:
“Inflation is taxation without legislation”
“I am favor of cutting taxes under any
circumstances and for any excuse, for any
reason, whenever it's possible.”
“We have a system that increasingly taxes
work and subsidizes non-work.”
“The real cost of government is measured
by what government spends, not by
receipts labeled taxes.”
BACK TO
Taxes
A Commodity Tax is a tax on goods.
Some truths about commodity taxation:
1. Who pays the tax does not depend on
who writes the check to the government;
2. Who pays the tax does depend on the
relative elasticities of demand and
supply;
3. Commodity taxation raises revenue and
creates lost gains from trade (deadweight loss).

Who pays the tax? It depends on
the relative elasticities of supply and
demand.
The less elastic side of the market
will pay the greater share of a tax
(bear more of the burden of a

SEE THE INVISIBLE HAND
This pleasure boat seems like a good thing to tax…
Or not: The Omnibus Budget Reconciliation Act of 1990
applied a 10% federal luxury tax to the retail sale of luxury
goods like pleasure boats with a sales price above $100,000.
Expected tax revenue? $9 billion. Reality?
•Sales of boats down 52.7%;
• Net loss of 30,000 jobs;
• The federal government paid out > $7 million
more in unemployment benefits to those workers
than it collected in luxury tax revenues.
BACK TO
The Burden of a Tax
The Omnibus Budget Reconciliation Act of 1990
applied a 10% federal luxury tax to the first retail
sale of luxury goods such as pleasure boats with a
sales price above $100,000.
The tax was originally projected to generate
revenues of $9 billion over five years after passage.
The tax was widely popular among policy makers
as a way to shift the burden of deficit reduction to
those who can best afford it (i.e. the Rich).
BACK TO
The Burden of a Tax
The results were not what was expected by
policy makers:
Sales of boats down 52.7%;
Net loss of 30,000 jobs;
The federal government paid out over $7 million
more in unemployment benefits to those workers
than it collected in luxury tax revenues.
BACK TO
The Burden of a Tax
The elasticity of supply for boats was
evidently less elastic than the elasticity of
demand for boats.
The federal luxury tax was quickly (and
quietly) repealed in 1993
BACK TO
The Burden of a Tax
You had to be an ignoramus to believe the luxury
tax was only going to soak the rich. The only
people it hurt was working people like myself,”
-Judy Ott, an assembly worker at the Viking
Yacht Company’s plant in New Jersey.
“All these people suffered needlessly because
the politicians in Washington needed a symbol to
sell the American people a new tax increase,”
- Viking’s co-founder Robert T. Healey.
BACK TO
The Burden of a Tax
So the next time you vote for politicians who are
going to “stick it” to the rich or corporations via
taxes, remember the “little guys” who will lose their
jobs as a result.
Why could the current efforts in the U.S. and
California (no less than THREE ballot initiatives to
raise taxes on the rich) cause more harm than
good?
“Democracy is two wolves and a sheep voting on
what’s for dinner”

Other applications:
Health Insurance Mandates and Tax Analysis
Mandates requiring employers to provide
health insurance to their workers may reduce
wages if labor supply is less elastic than
demand for workers.
BACK TO
The Burden of a Tax
Health Insurance Mandates and Tax Analysis
Many people believe that healthcare benefits
are paid by their employer
Most don’t realize that their wages are lower as a
result
Healthcare tax mandate on employers raises the
cost of labor supply
BACK TO
The Burden of a Tax
Which side of the market is more inelastic, the
demand for labor or the supply of labor?
Firms can substitute capital (machines) for labor,
move overseas to avoid the tax, or simply close down
Employees are unlikely to be able to quite working (if
taxed) or less likely move overseas than their
employers
For most workers, the elasticity of their supply of labor
is lower than their employers’ elasticity of demand for
labor
BACK TO
The Burden of a Tax
Health Insurance Mandates and Tax Analysis
It is likely that workers will bear most of the cost of
mandated health insurance via lower wages
This is not to say that the law is a bad idea
What is a bad idea is voters believing that somehow
healthcare has been made “free.”
They are being duped by less-than-forthcoming
politicians, i.e. they are depending on your
economic ignorance
BACK TO
The Burden of a Tax
Same argument applies to FICA and similar
payroll taxes
Workers bear most of the tax burden even though
employers “pay half the tax” via wages lower than
without FICA
Why? The labor supply curve is more inelastic than the
labor demand curve
There is no free lunch (the politician’s weapon of
choice)

Other applications:
Who Pays the Cigarette
tax?
If manufacturers of
cigarettes can easily dodge
state taxes (via smuggling),
then it’s possible the tax will
not discourage smoking.
National cigarette taxes are
more effective in deterring
smoking: no interstate taxdodging occurs.
BACK TO
The Burden of a Tax
Who Pays the Cigarette Tax?
Smokers have an inelastic demand for cigarettes
of about .5
Cigarette companies have a very high elasticity
of supply to any one state since they can easily
ship their products to other states with relatively
lower taxes
Buyers bear nearly all of the tax
BACK TO
The Burden of a Tax
Real world example:
Taxes range from $.07 in S. Carolina to $2.57/pack in
New Jersey
Cigarettes sell for $3.35/pack in S. Carolina, while
cigarettes in New Jersey are priced at $6.45
After-tax price received by sellers is $3.28 in SC
compared to $3.88 in NJ
Prices vary probably due to differences in related
costs

The Deadweight Loss of a Tax
Another example of DWL:
Imagine that you want to go to New York on a
trip. You value the trip at $50 and a bus ticket costs
$40. Do you take the trip?
A. Yes. The value ($50) of the trip exceeds the cost
of the ticket ($40) so you travel to New York.
How much consumer surplus (net value) do you get
from the trip?
A. $10=$50-$40.
BACK TO
The Deadweight Loss of a Tax
The government taxes bus tickets which raises the
price of a bus ticket to $60. Do you take the trip?
A. No. The value of the trip is now less than the price
of the ticket.
What happened to the $10 consumer surplus which
you used to get when there was no tax?
A. It's gone since no trip takes place.
Did the government get any tax revenue from you?
A. No.
Key idea: Consumers lose but the government does
not gain from trips that are not taken.

Deadweight Loss and Elasticity
Deadweight Losses are Larger the More Elastic the Demand Curve:
If the demand is inelastic, a tax will not deter many trades.
BACK TO
Subsidies
A subsidy is a reverse tax where the government
gives money to consumers (or producers).
Subsidy = Price Received by Sellers – Price Paid by
Buyers
Some facts about subsidies:
1. Who gets the subsidy does not depend on
who receives the check from the
government;
2. Who benefits from the subsidy does depend
on the relative elasticities of demand and
supply;
3. Subsidies must be paid for by taxpayers and
they create inefficient increases in trade
(deadweight loss).
BACK TO
The Subsidy “Wedge”
A subsidy drives a wedge between the price received by sellers and the
price paid by the buyers.

BACK TO
Subsidies
When demand is more elastic than supply, suppliers bear
more of the burden of a tax and receive more of the benefit
of a subsidy.

Who benefits most from the large
agricultural water subsidy?
Farmers in California’s Central Valley typically pay $20-$30 an
acre-foot for water that costs $200-$500 an acre-foot
Hint: which is more elastic: demand or supply for cotton?
a) California cotton suppliers
b) California cotton buyers

King Cotton and the Deadweight Loss of
Water Subsidies
In the Central Valley of California, farmers pay
$20-$30 an acre-foot for water that costs $200$500 an acre-foot
The difference represents the government subsidy
Rice, cotton, alfalfa are grown in a “Cadillac
Desert”
Other subsidies abound
Ex) crop subsidies for cotton
Ex) Subsidized water used to grow subsidized corn
to feeds cows producing subsidized milk
BACK TO
Subsidies
All of these subsidies represent “deadweight
loss” since such crops can be grown more
cheaply elsewhere
Who benefits from the water subsidy?
Cotton suppliers or cotton buyers?
Remember that the benefit of a subsidy falls on
the more inelastic side of the market
Elasticity of demand for California cotton is much
higher than the elasticity of supply. Why?
BACK TO
Subsidies
Demand elasticity is very high since cotton grown
outside of California is a perfect substitute (i.e.
many substitutes)
Supply elasticity is lower as a result, hence
subsidy flows to producers
Without the subsidies, there would be much
less water intensive farming
Would definitely affect the debate on
environmental issues in Central Valley

Should Los Angeles subsidize the Cirque du Soleil?
• In 2009 the Los Angeles City Council approved a $30m loan for a
10-year Production of Cirque du Soleil in Hollywood
• What are the costs? Benefits?
Should the government be in the entertainment business?

Wage Subsidies
The minimum wage is the clearest example of a
price floor in the United States.
Such a policy, however, can hurt low-skilled
workers by reducing employment.
Some economists believe that a better
approach would be to subsidize employers
(demanders of labor).
This approach leads to a higher wage and a
higher level of employment.

Some Subsidies have Serious Benefits:
Wage Subsidies Increase Employment
A wage subsidy costs the government money but increases employment
from Qm to Qs (and reduces welfare payments)

Wage Subsidies
Suggested by Edmund Phelps. Nobel Prize
winner in Economics
It would be expensive, paid by taxpayers
Would result in more low skilled workers being
employed
Costs could be offset by social benefits: less
crime, less dependency, etc

If demand of some good is more elastic than
supply and a tax is imposed on the consumption
of the good, who will bear more of the burden of
the tax?
a) Producers, because consumers have a greater
ability to change their behavior in response to
the tax.
b) Both parties will share the burden equally.
c) Consumers, because they pay the tax out of
pocket.
d) The government, because the tax will cause
less of the good to be produced and
consumed.
