Demand-side and Supply-side Policies Macroeconomics Section 3.4 1
2
Automatic stabilizers when economy overheats 2 Social benefits and taxes can act as automatic stabilizers Unemployment Falls Social payments decline Government spending declines AD falls Higher income: higher taxes Less disposable income Reduction in Consumption AD falls
3
Automatic stabilizers in recession 3 Social benefits and taxes can act as automatic stabilizers Unemployment increase Social benefits increase Government spending increases AD rises Lower incomes: lower taxes More disposable income Increase in Consumption AD rises

Fiscal and Monetary Policies Demand-side & Supply-side Policies 4
5
Discretionary Stabilization Policies Discretionary Policies aim to Stabilize the Economy Fiscal Demand-side Policies Supply-side Policies Monetary 5
6
Demand-side Policies Fiscal Policy Focus on taxes and/or government spending Monetary Policy Focus on interest rates 6
7
Expansionary Fiscal Policies (in recession) Fiscal Policy Increase government spending Decrease personal and/or business taxes Combination of both policies 7
8
The Government Budget and the National Debt (Public Debt) Government Budget = annual government spending Budget Surplus = Tax Receipts > Spending Budget Deficit = Tax Receipts < Spending National Debt = Money borrowed domestically and/or internationally (foreign debt) to balance the budget National Debt often expressed as % of GDP 8

Contractionary Policies (in inflation) Fiscal Policy Decrease government spending Increase personal and/or business taxes Combination of both policies 11
12
Strengths of Fiscal Policy Combats rapid and escalating inflation Government spending directed at redistribution of income Government spending on the provision of public goods and services Combats a deep recession 12
13
Weaknesses of Fiscal Policy Time lags in recognizing the problem, determining and implementing policies Inadequate information Political constraints Crowding-out i.e. Government borrowing raises interest rates Tax cuts may be ineffective Unable to fine tune economy 13
14
The Neoclassical/Monetarist Challenge Argument that discretionary fiscal polices that try to stabilize the economy are so flawed that they actually cause instability Monetarist argue that governments should: 1. Take a long-term view about spending and taxation to achieve social priorities 2. Ensure steady supply of money 3. Ensure price and wage flexibility 4. Focus on supply-side policies to achieve economic growth 14
15
Supply-side Policies Market-orientated/ Interventionist- orientated 15
16
Growth Policies Discretionary Fiscal Policies that aim to increase potential output Market-orientated Policies Interventionist- orientated Policies 16
17
Supply-side Policies Market-orientated 17
18
Market-orientated Policies Economic Growth through supply-side policies Price Stability Full Employment 18
19
Market-orientated Supply-side Policies: Objectives Reduce Government Sector Improve incentives for private initiative Ensure the Labor market responds to supply and demand Free Trade (Discussed in Section 4) 19
20
Reduce Government Sector Privatization to increase incentives and reduce costs Restrict Monopolies Deregulation to encourage competition and efficiency Private Financing of Public Services Outsourcing to Private Sector 20
21
Reduce Government Sector: Pros and Cons More competition Greater efficiency Lower costs Improved services Public monopoly becomes private monopoles Private financing expensive Loss of flexibility Job losses Dangers of deregulation 21
22
Improve incentives by lowering taxes Improve incentives for private initiative Reduce personal taxes to encourage more work Lowering taxes on interest income to stimulate saving and investment Lowering business taxes to increase investment, R&D and innovation 22
23
Improving incentives : Pros and Cons Increase quantity of labor and capital Reduce unemployment Increase saving and investment Increase R&D Reducing taxes impacts AD People work less & spend more Inflation Worsen income distribution Increase government budget deficit 23
24
Make labor more responsive to supply and demand Abolish minimum wage to provide greater flexibility increase profits and spur economic growth Weaken unions to provide greater flexibility, increase profits and spur economic growth Reduce unemployment benefits to lower unemployment rates Reduce job security so firms can fire at will 24
25
Make labor more responsive to supply and demand : Pros and Cons Labor markets more competitive Wages respond to supply and demand Lower costs and higher profits Increased employment Increase income inequality Unemployment benefits help to maintain consumption 25
26
Supply-side Policies Interventionist-orientated 26
27
Government policies to improve industry Support industry Provide education and health to improve quality of labor Fund and provide incentives for R&D Support SMEs (small to medium sized firms) Support infant industries through grants, subsidies tax exemptions & tariffs Invest in infrastructure 27
28
Government policies to improve industry: Pros and Cons Provide an underpinning for economic growth Inefficiencies and resources misallocation Opportunity costs Increased taxes 28
29
Shifting the SRAS and the LRAS in the AS-AD Model 29 SR Focus on the price of labor, inputs and taxation and legislation LR Focus on new technology, new production methods, quality and/or quantity of FOPs
30
The Multiplier, accelerator and crowding effect HL Topics 30
31
The Multiplier Effect Any change in Consumption, Investment, Government Spending and Net Exports Change components of AD Induced expenditures, a change reaction of further expenditures Change in real GDP 31
32
32 Marginal Propensity Marginal Propensity to Consume MPC Marginal Propensity to Save MPS Marginal Propensity to Tax MPT Marginal Propensity to Import MPI 1
33
Example of the Multiplier in Effect Initial Spending by government$100m 2 nd Round of Spending$60m 3 rd Round of Spending$36m 4 th Round of Spending$21.6m 5 th Round of Spending$12.96m And So On Last Round$0.01m Total Spending, including initial spending by government $249.99m 33 Assumption 60% of additional income spent on Consumption (MPC = 0.6) The Multiplier = 1/1-MPC
34
The Multiplier Effect
35
The Accelerator Theory & the Combined multiplier/accelerator effect Argues that small changes in GDP produces larger changes in investment spending. These fluctuations interact with the Multiplier effect to increase the momentum of business cycle. 35
36
Crowding-out Effect Governments borrow to finance fiscal polity Interest rates rise Private investment falls 36
37
Crowding-out Effect
