2. Introduction
• The term "supply-side economics" was thought for some
time to have been coined by journalist JudeWanniski in
1975.
• According to Robert D. Atkinson the term "supply side" was
first used in 1976 by Herbert Stein (a former economic
adviser to President Richard Nixon)
• Latterly this term repeated by JudeWanniski.
• Its use connotes the ideas of economists Robert
Mundell and Arthur Laffer.

(1911 – 2004)
• United States (1981 – 89)
• United Kingdom (1979 – 1990)
called as Reaganomics
4. “
”
economic growth can be most effectively created
by using incentives to people to produce (supply)
good sand services such as adjusting income tax
and capital gains tax
Meaning
Supply-side economics is the theory that says increased
production drives economic growth.The factors of
production are capital, labor, entrepreneurship, and land.
6. 4 Pillars of
Reaganomics
1. Cutting downTax
2. Slowing down the growth of public
expenditure
3. Curtailing the burden of regulations
4. Reducing the growth of money
supply
7. Propositions of supply-side Economics
•Taxation and Labour – supply
•Incentives to Save and Invest
•Cost – Push Effect of theTaxWedge
•Underground Economy
•Tax Revenue and Laffer Curve
8. Supply SideVs Demand Side Economics
• Supply-side is the opposite of
Keynesian theory. It states that
demand is the primary driving
force of economic growth.
Supporters use fiscal policy to
better the lives of consumers
regardless of whether they work or
not.
• The demand side economics had
completed ignored the fiscal
implications of a tax cut on
aggregate supply.The
phenomenon of stagflation in
western countries during 1970s
pushed the demand side
economics for introspection and to
crucial test.
10. Essentials of Supply Side Economics
• Validity of Say’s Law of Market
• Determinants of Output or supply
• Classical interest – elastic saving and investment
• Determinant of growth rate of labour
• Free market system
11. Implications of Supply Side Economics
Tax rates raise tax revenues
Reduction in tax rates cure stagflation
Reduction in government spending
Monetary policy
Increased depreciation
Reduction in welfare benefits
Reducing union power
Deregulation and privatisation
Free trade and capital movements
12. Laffer Curve
•the Laffer curve illustrates a theoretical
relationship between rates of taxation and
the resulting levels of the government's tax
revenue.
13. Arthur Laffer developed in 1974.
He argued that the effect of tax cuts on
the federal budget are immediate.They
are also on a 1-for-1 basis. Every dollar cut
in taxes reduces government spending,
and its stimulative effect, by exactly one
dollar.
16. Recommendations
• Reduction in personal and corporate income tax rates
• Change in tax laws
• Reduction in government regulation
• Balancing of federal budget
• Stabilizing money growth rates
• Free international trade and capital movements
• Reduction in the strength of labour
17. Criticism of Supply Side Economics
• More ideology, less analysis
• No solution of poverty and unemployment
• Tax cuts not dependable
• No trickle down effects and rise in income inequalities
• Weak as a theory of underdevelopment
• Less role for public sector is not ideal
• Difficult to locate optimal tax point or the exact shape of the Laffer curve
• It is not possible to measure work effort specifically as a result of tax cut
• Critics argue that some persons have target real income when taxes are reduced,
they will work less and have more leisure to maintain their target income.
