WHISKEY’S FOR DRINKING… AND TAXING.
Taxes matter: Washington’s 1791 tax on whiskey distillers led to the Whiskey Rebellion of 1794, the decline of small distillers, and local economies—and the rise of the Republican Party.

THE EFFECT OF AN EXCISE TAX ON QUANTITIES AND PRICES
Taxes drive a wedge between the price buyers pay and the price sellers receive.
To analyze the effects, we’ll graph two scenarios:
when the tax is levied on sellers
when the tax is levied on buyers
The incidence of a tax is a measure of who really pays it.

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 went down 52.7%.
Net 30,000 jobs were lost.
The federal government paid out more than $7 million more in
unemployment benefits to those workers than it collected in
luxury tax revenues.
The federal luxury tax was repealed in 1993.

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?
14. Producers, because consumers have a greater ability to change
their behavior in response to the tax.
Both parties will share the burden equally.
Consumers, because they pay the tax out of pocket.
The government, because the tax will cause less of the good to
be produced and consumed.

true for the tax to actually deter the most people from eating
junk food: Should junk food demand be elastic or should it be

THE BENEFITS AND COSTS OF TAXATION
More children are born in late December than in early January,
and the extra births appear to be clustered among those who
have the most to gain from a tax deduction.
Unless you’re a cynic, or an economist, I realize you might have
trouble believing that the intricacies of the nation’s tax code
would impinge on something as sacred as the birth of a child.
But it appears that you would be wrong.

loss), then policymakers should choose the goods with the
lowest price elasticities.

TAX FAIRNESS AND TAX EFFICIENCY
Two principles of tax fairness:
The benefits principle: Those who benefit from public spending
should bear the burden of the tax that pays for that spending.
The ability-to-pay principle: Those with greater ability to pay a
tax should pay more tax.
There is usually a trade-off between equity and efficiency: The
system can be made more efficient only by making it less fair,
and vice versa.

UNDERSTANDING THE TAX SYSTEM
Some important taxes and terms:
The tax base is the measure, such as income or property value,
that determines how much tax an individual or firm pays.
Taxed on each barrel of whiskey you produce? Then whiskey is
your tax base.

UNDERSTANDING THE TAX SYSTEM
Some important taxes and terms:
Lump-sum tax is the same for everyone, regardless of any
actions people take.
Income tax depends on income from wages and investments.
Payroll tax depends on the earnings an employer pays to an
employee.
Sales tax depends on the value of goods sold.
Profits tax depends on a firm’s profits.
Property tax depends on the value of property, such as a home.
34. Wealth tax: a tax that depends on an individual’s wealth.

UNDERSTANDING THE TAX SYSTEM
The tax structure specifies how the tax depends on the tax base.
A progressive tax takes a larger share of the income of high-
income taxpayers than of low-income taxpayers.
A regressive tax takes a smaller share of the income of high-
income taxpayers than of low-income taxpayers.
The marginal tax rate is the percentage of an increase in income
that is taxed away.
