This document provides an overview of supply-side economics. It discusses how supply-side economics focuses on using tax cuts and deregulation to spur economic growth by increasing production. The four pillars of Reaganomics are outlined as cutting taxes, slowing spending growth, reducing regulations, and controlling money supply. The Laffer Curve is introduced as illustrating the relationship between tax rates and tax revenue, suggesting that extremely high tax rates can reduce revenue. Criticisms of supply-side economics include that it is more ideology than analysis and tax cuts may not reliably increase tax revenue or trickle down benefits.

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.

5. Meaning
Supply-side fiscal policy focuses on creating a better climate for businesses. Its
tools are tax cuts and deregulation.

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.

14. Laffer Curve
When the tax rate is zero the
government tax revenue is
certainly zero

15. Policy Recommendations
Supply Side Economics

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.
