GOVERNMENT MACRO INTERVENTION
Broad topic objectives: To explain; The aims of macro policies The Phillips curve & Laffer curve The possible conflicts in policy framework
2
Introduction and aims Reading & discussion tasks from page 265.
Highlight the major macroeconomic objectives. Compare your answers.
3
Aims of macroeconomic policy
1. Sustainable economic growth 2. Low & stable price inflation 3. Equilibrium or stable BOP position 4.Full employment/low unemployment . 5.Minimal exchange rate fluctuations
4
Relationship between inflation & unemployment.
It is depicted by the ‘Phillips curve’ Its was developed by prof A.W. Phillips of New Zealand but it was Milton Friedman who put it into mainstream econ thinking in the 1970’s.
5
In 1958 ,Phillips plotted 95 years of data of UK wage inflation against unemployment.
He found an inverse relationship btn inflation and unemployment at least in the SR
6
i.e. A fall in unemployment may cause higher inflation due to the extra AD generated leading to eventual rise in prices. Task: draw fig page 267. [short run Phillips curve] NB: NAIRU is defined where the curve cuts the x axis
8
The long run Phillips curve
Its also called the expectations – augmented Phillips curve. Milton Friedman argued that the SR curve is drawn at a given level of inflation expectations. As expectations rises, the curve will shift upwards at the level of NAIRU. .
9
There will be no trade off btn inflation & unemployment in the LR leading to a vertical LR Phillips curve. Prep- page 268
11
Task : page 266 Read & make short notes on the relationship between internal & external value of money. Discuss on the uniqueness of this relationship. It’s the relationship btn inflation & exchange rate
12
Relationship between BOP & inflation
It’s shown by the J-curve effect. High inflation reduces price competitiveness & export revenue. Imports expenditures rise worsening the current account balance. Again, a current account surplus may raise net exports & AD due to high incomes.
13
High AD may raise domestic prices and reduce the internal value of money.
However, the rising net X may cause the exchange rate to rise which makes M cheaper. This may encourage local firms to reduce their prices too.
14
Problems arising from policy conflicts (page 269)
E.g. pursuit of a low rate of inflation may increase unemployment according to Phillips curve. To avoid conflicts btn policy objectives a govt must employ separate policies for each objectives.
15
E.g. to reduce unemployment, a government may cut taxes instead of raising money supply.
Task: copy the definition of Tinberg’s rule from page 269 Read the hand out from economicscafé.com
16
Economics Lecture Notes – Chapter 12
Prep: page 270
17
Government failure Occurs when govt intervention reduces rather than increasing economic performance. i.e. intervention worsening market failure E.g. To correct a negative output gap, a govt may underestimate the national income multiplier.
18
Too much spending will thus cause a positive output gap!
In other cases, policy effectiveness is affected by time lags e.g. changes in tax structures takes time to construct & administer.
19
Some policies may also be counter-cyclical i. e
Some policies may also be counter-cyclical i.e. going against fluctuations in economic activity. E.g. during a boom the Fed may raise interest rates to encouraging savings & reduce borrowings.
20
Economic agents may however continue to borrow & spend if they are optimistic about the future.
The failure also manifest in the implementation of political manifestos by new govts.
21
LAFFER CURVE: It shows the relationship between tax rates and tax revenue collected by governments. As tax rates increases, tax revenue collected increases up to a certain point. There’s an optimum tax rate that must be set so as to maximize tax revenues.
23
Raising tax rate beyond the optimum rate would be govt failure & would encourage tax evasion.
A rate of 0% and 100% will yield no tax revenue Explain why this is so
24
Plenary Read the summary from page 272
Do the revision questions from page 272.
