Recap & move forward…

2. Recap
Name ‘FIVE’ causes of UK’s rise in inflation.

3. Recap F= Fuel I = Imports create higher costs V = VAT
E= exchange rates

4. Recap In theory – what are the 2 different types of inflation?
Demand pull inflation
Cost push inflation

9. Deflation
Is it good or bad?

10. Deflation Deflation is a sustained fall in the general price level
A sustained period of negative inflation
The internal value of money rises

11. Deflation for some products

15. Demand side causes of Deflation
A Large (adverse) Fall in AD
Exogenous shocks to the economy
A global recession leading to a fall in exports and investment
A rise in the exchange rate (leading to lower exports and cheaper imports)
Declines in domestic and international asset prices
Deliberate attempts by macroeconomic policy to reduce AD through tightening of fiscal and/or monetary policy

16. Multi choice…

17. Demand-pull inflation is most likely to be caused by
MC practice
Demand-pull inflation is most likely to be caused by
A total spending exceeding productive capacity.
B an increase in output.
C a rise in raw material prices.
D a rise in interest rates.
Mrs Gordon's notes

18. An economy is most likely to be in the boom phase of the trade cycle when there is a rise in
A business pessimism.
B the savings ratio.
C spare capacity.
D the demand for imports.

19. Real incomes rise whenever
A nominal incomes rise.
B the price level rises by more than nominal incomes.
C nominal incomes rise by more than the price level.
D the rate of inflation slows down.

20. What’s so BAD about inflation?
“RPI is an aggregate figure” – what does this mean?
Why are interest rates on mortgages such an important monetary tool to control inflation?

24. Supply side causes of deflation
An Increase in Long Run Aggregate Supply
The supply potential of the economy has been boosted by a series of beneficial shocks such as
Impact of rapid technological advances
Reductions in the international prices of commodities and capital goods
Higher productivity which drives down unit cost of production
Exploitation of economies of scale leading to lower LRAC
Excess supply in some industries due to over-investment in new capital machinery i.e. deflation results from a persistent demand deficit over existing and potential productive capacity.

25. Deflation – good and bad points!
Impact on Households?
Consumers?
Employees?
Businesses?

26. Consequences of Deflation
Holding back on spending:
Consumers may opt to postpone demand if they expect prices to fall further in the future
Debts increase: The real value of debt rises when the general price level is falling and a higher real debt mountain can be a drag on confidence
Mortgage payers on fixed mortgage interest rates will see the real cost of servicing their debt increase
The real cost of borrowing increases: Real interest rates will rise if nominal rates of interest do not fall in line with prices
Lower profit margins: This can lead to higher unemployment as firms seek to reduce their costs.
Confidence and saving: Falling asset prices such as price deflation in the housing market hit personal sector wealth and confidence –leading to further declines in AD. Higher savings can lead to the paradox of thrift

27. Past paper practice

29. QUESTIONS Explain what is meant by the term “deflation”.
With reference to Extract 1, explain the effect on GDP of the change in asset prices in 1990.
Explain why “deflation needn’t be all bad”? (line 28, extract 2)
With reference to the extracts, examine the problems associated with a long period of deflation.
Assess the relative effectiveness of using monetary and fiscal policy to move the economy out of a period of deflation.
How might the continuing deflation in Japan affect the global economy?
