Analysis of a
Tax-and-Spend
Policy
Government
increases
spending, but

shifting AS to the
left.

Supply-Side
Economics
and the
Laffer
Curve
•Taxes are a
disincentive to
productive activity.
•At marginal tax rates
greater than t, the tax
base shrinks at a
faster rate than the
increases in marginal
tax rate.
•Net result: increases
in marginal tax rates
beyond t result in
reduced tax revenues.
