1
Q

inflation

A

a sustained rise in the general price level over time. this means that the cost of living increases and the purchasing power of money decreases

2
Q

deflation

A

the opposite of inflation, where the average price level in the economy falls.
there is a negative inflation rate

3
Q

disinflation

A

the falling rate of inflation.
this is when the average price level is still rising, but to a slower extent. this means goods and services are relatively cheaper now than a year ago, and the purchasing power of money has increased

4
Q

inflation objectives

A

-aim to keep inflation low and stable
-inflation target at 2%.
this aims to provide price stability for firms and consumers and helps them make decisions in the long run.
-price stability is measured with consumer price index (CPI)
-

5
Q

hyperinflation

A

when the rate of inflation is high and accelerating to the extent that it is out of control.
-growth of the money supply could cause this ( if bank of england printed more money, there would be more money flowing in the economy)

6
Q

calculating the inflation rate in the uk

A

-CPI is calculated by measuring the change in the value of a basket of goods and services.
-it measures household purchasing power with the family expenditure survey- it finds out what consumers spend their income on.
>from this a basket of good is created
>the goods are weighed according to how much income is spent on each item

7
Q

limitations of CPI when measuring inflation

A
  • the basket of goods is only representative of the average household.
  • hard to make historical comparisons since technology twenty years ago was different
  • different demographics have different spending patterns
  • CPI is slow to respond to new goods and services, even though it is updated regularly
8
Q

retail price index (RPI)

A
  • alternative measure of inflation
    -unlike CPI, RPI includes housing costs, such as payments on mortgage interest & council tax - this more accurately reflects the cost of living.
    -tends to have a higher value than CPI due to the inclusion of housing costs
    -has been used for much longer than CPI, makes it better for comparisons over time
    -it is unique to the uk, not consistent with the european central banks inflation measurement like the CPI is.
    therefore CPI is more accurate for making comparisons between european countries
9
Q

calculating using index numbers

A

-used to make comparisons between years and to measure the magnitude of change over time.
>pick a base year (always has an index value of 100)
>raw number/ base year raw number x 100
-to make comparisons use percentage change of the index number
>%change= difference/original x 100

10
Q

causes of inflation

A
  • demand pull

- cost push

11
Q

demand pull inflation

A
  • this is from the demand side of the economy.
  • when AD is growing unsustainably, there is pressure on resources.
  • producers increase their prices and earn more profit.
  • usually occurs when resources are fully employed
12
Q

triggers for demand pull inflation

A

-a depreciation in the exchange rate, which causes:
>imports to become more expensive
>exports to become more cheaper,
this causes AD to rise

  • fiscal stimulus in the form of lower taxes or more government spending. this means consumers have more disposable income, so consumer spending increases.
  • lower interest rates makes saving less attractive and borrowing more attractive, consumer spending increases.
  • high growth in uk exports markets means uk exports increase & AD increases
13
Q

demand pull inflation diagram

A
  • AD increases from AD to AD1
  • prices increase from P to P1
  • SRAS stays the same
14
Q

cost push inflation

A

-from the supply side of the economy, and occurs when firms face rising costs

15
Q

cost push inflation happens when…

A
  • raw materials become more expensive.
    e. g. when oil prices rise
  • labour becomes more expensive. this could be through trade unions
  • expectations of inflation. if consumers expect prices to rise, may ask for higher wages to make up for this. this will trigger more inflation
  • indirect taxes could increase the cost of goods such as cigarettes/fuel, if producers choose to pass the costs onto consumers
  • depreciation in the exchange rate, which causes imports to become more expensive, which pushes up the price of raw materials
  • monopolies using their dominant market position to exploit consumers with high prices
16
Q

cost push inflation diagram

A
  • AD stays the same
  • SRAS shifts to the left SRAS2
  • quantity shifts to the left to q1 and p increases to p1
17
Q

evaluation of demand pull inflation

A
  • considered less harmful than cost push inflation as it is associated with increasing AD and improving living standards.
  • businesses could use increased profit margins to invest in new capital, increasing productive capacity in the future.
18
Q

evaluation of cost push inflation

A

-tends to be more harmful than demand pull inflation as it is associated with falling output (AS) (known as stagflation)

19
Q

high and stable inflation rates

A
  • high inflation rate likely to cause more problems than a low rate.
  • stable inflation rate is likely to cause fewer problems as it is easier for consumers, workers and firms to plan ahead
20
Q

affect on exports

A

depends on inflation rates abroad.

if inflation rates are higher abroad, exports may still be competitive

21
Q

different effects on different groups

A

may be harmful to some groups but benefical to others

e.g. the government as a borrower and beneficiary of fiscal drag may gain, tax payers and savers may lose

22
Q

consequences of inflation:

advantages of low inflation

A
  • encourages people to spend more money before prices increase, keeping the economy moving
  • price stability increases the ability for individuals and organisations to plan their finances.
  • erodes value of debt over time
  • businesses can reduce their real wage bill by raising money wages by less than inflation- may stop firms making workers redundant to cut costs
23
Q

consequences of inflation:

disadvantages of high inflation

A
  • reduces consumer & business confidence, which can lower spending & lead to recession
  • high inflation discourages investment as firms are less able to predict when their investment will be returned
  • increases prices & reduces international competitiveness
  • reduces the value of savings meaning groups like pensioners become worse off in real terms.
  • real incomes fall with inflation, so workers will have less disposable income
24
Q

consequences of inflation:

disadvantages of high inflation (2)

A

menu costs- changing the labelling of prices incurs costs and happens more frequently at times of high inflation.

shoe leather costs- the costs of comparing prices from a variety of sellers.

inflationary noise- it becomes more difficult for consumers and businesses to decide what is a ‘fair’ price in time of high inflation, leading to inefficient choices.

if interest rates do not increase in line with inflation there may be a random redistribution of income from savers to borrowers

workers might demand higher wages, which could increase the cost of production for firms

fiscal drag may occur with tax bands not being adjusted in line with inflation and so workers pay may be dragged into higher tax bands

25
Q

causes of deflation

A

-a fall in aggregate demand:
>usually caused in recessions, when output and demand are decreasing.
this can be illustrated in the diagram. a fall in AD from AD2 to AD1 or AD4 to AD3 causes the price level to fall. however, usually falling AD causes disinflation rather than deflation.

  • if the supply of money falls in the economy, there could be a fall in the average price level. this can be caused by a tightening of monetary policy, such as with higher interest rates
  • significant spare capacity in the economy
  • deflationary expectations, where customers anticipate falls in average prices and so postpone consumption. this exacerbates falls in AD, pushing prices down further
  • an appreciating currency, reducing the price of imports
26
Q

causes of deflation evaluation

A
  • short term falls in the price of inputs tend to be less damaging to an economy as these may encourage consumers to spend money while prices are lower.
  • deflation caused by falls in AD tend to be more damaging as these falls can become in -grained in an economy
27
Q

consequences of deflation

A
  1. there is an increase in the value of money
  2. consumers choose to delay purchases as they expect prices to fall in the future. this reduces AD further- deflation ingrained in the economy
  3. real value of debt increases
  4. lower profit margins as businesses cut their prices
  5. falling value of assets, such as houses, hits wealth
  6. redistribution of income from debtors to creditors
28
Q

consequences of deflation evaluation

A
  • a small amount of deflation for a short period caused by a fall in the cost of production, may be beneficial as consumers real wealth increases and they are able to increase their standard of living.
  • however, when deflation becomes ingrained, it can have a damaging effect on the economy because of its impact on consumers expectations and the impact this has on AD
29
Q

bad deflation (malign)

A

-AD decreases, causing a
>recession/depression
>general price level- negative inflation
-a sign that average income (in households) is falling and people are spending less.

unemployment- low confidence
negative expectations- possible deflationary spiral
downward multiplier/accelerator- liquidity trap

30
Q

good deflation (benign)

A

-increased competition
-improvements in technology
-increased productivity
-globalisation- emergence of cheaper manufactured goods from china
-increase real disposable income & consumption (purchasing power & living standards)
people can consume more because prices have fallen , while the quality of products have improved

31
Q

quantitative easing

A
  • helps stimulate the economy.
  • since the interest rates are already very low, it is not possible to lower them much more. this means the bank had to adopt another measure: pumping money into the economy.
  • the bank brought assets in the form of government bonds using the money they have created.
  • this is then used to buy bonds from investors, which increases the amount of cash flowing in the financial system.
  • encourages more lending to firms and individuals.
  • the theory is that this encourages more investment, more spending and hopefully higher growth.
  • a possible effect of this is that there could be higher inflation.
