2.1 economic performance Flashcards
what is gross domestic product
- the standard measure of output, which allows us to compare countries
- it is the total value of goods and services produced in a country within a year
explain the difference between Real and Nominal GDP, giving an example where we might want to use each
- real GDP strips out the effects of inflation whilst nominal GDP does not
- real values can be described as the volume of national income i.e. the size of the basket of goods, whilst nominal values represent the value of the national income i.e. the monetary cost of this basket of goods
explain the difference between total and per capita GDP, giving an example where we might want to use each
- total GDP represents the overall GDP for the country whilst GDP per capita is the total GDP divided by the number of people in a country
explain the difference between value and volume of, for example, exports
value of national income - is its monetary value at the prices of the day
volume - is national income adjusted for inflation and is expressed either as index number or in money terms
explain the difference between GNP and GNI
GNP - value of goods/services over a period of time through labour or property supplied by citizens of a country both domestically and overseas
GNI - value of goods/services produced by a country over time plus net overseas intrest payments and dividends
why must we be careful when comparing GDP across different countries?
-
why must we be careful when comparing GDP over time?
-
what is meant by ‘Purchasing Power Parity’?
an exchange rate of one currency for another which compares how much a typical basket of goods in the country costs compared to one in another country
why might PPP be useful?
takes into account the cost of living so it helps us better compare living standards
what is economic growth?
an increase in the long term productive potential of the economy; an increase in the amount of goods/services that are produced
how can inaccuracies of data be a problem when comparing standards of living
- some countries are in efficient at collecting or calculationg data
- there is a ‘hidden’ or ‘black ‘ market in which peoplle work to avoid declaring their income
- GDP does not take into account home-produced services
- methods used to calculate GDP will change over time
- errors in calculating the inflation rate means real GDP will be slightly inaccurate
how can inequalities be a problem when comparing standards of living
- an increase in GDP may be due to a growth in income of just one group of people and so therefore a growth in the NI may not increase living standards everywhere
- income distribution changes over time and varies between countries so makes comparisons difficult
how can the quality of goods and services be a problem when comparing standards of living
- the quality of goods and services is much higher than those fifty years ago, but this is not necessarily reflected in the real price of these goods and services
- living standards may have increased more than GDP would suggest since the quality of goods and services has improved greatly
- improved technology may allow prices to fall, suggesting falling living standards, when this is not the case
how can comparing different currencies be a problem when comparing standards of living
- there are issues over which unit should be used to compare figures: they are usually converted into US dollars because of the size of the American economy
- some people argue that Purchasing Power Parity should be used to take into account the impact of differences in the cost of living in different countries
how can spending be a problem when comparing standards of living
- some types of expenditure, such as defence, does not increase standard of living but will increase GDP
- for example, the GDP of the UK was higher during the Second World War than in the 1930s because a lot of money was spent on defence which increased GDP but it is difficult to argue that standard of living was higher in the Second World War
- this therefore makes comparisons difficult as spending varies overtime and between countries
what is inflation?
the general rise in prices of goods and services which erodes the purchasing power of money
what is deflation?
a persistant fall in prices of goods and services
what is disinflation?
a reduction in the rate of inflation
what does CPI include and how is it measured
- the Office for National Statistics (ONS) collects prices on 710 goods and services from 20,000 shops in 141 locations and online sites and the prices are updated every month, with collectors visiting the same retailers to monitor identical goods
- new items are added to the list every year, such as microwaveable rice and nail varnish , whilst others are taken away, including organic carrotsa
- all these prices are combined using information on the average household spending pattern to produce an overall price index
- the average household spending is worked out through the Living Costs and Food Survey, where around 5,500 families keep diaries of what they spend over a fortnight
limitations of CPI
- It is impossible for the figure to take into account every single good that is sold in the country and so therefore the CPI is not totally representative
- different households spend different amounts on each good and so therefore the CPI only measures an average rate of inflation, and is not totally representative
- it does not include the price of housing and so, since this has tended to rise more than the price of other goods, the data may be lower than it should be
- it is difficult to make comparisons with historical data as the figure is more recent
- it was only used since 1996 with estimates going back to 1988 which means that levels of inflation using CPI can only be accurately compared back to then
what does PRI include and how is it measured
- RPI includes housing costs such as mortgage and interest payments and council tax, whereas CPI does not
- CPI takes into account the fact that when prices rise people will switch to product that has gone up by less, therefore, the CPI is generally lower than the RPI
- RPI excludes the top 4% of income earners and low income pensioners as they are not ‘average’ households whilst CPI covers all households and all incomes
what are the causes of inflation
demand pull
cost push
growth of money supply
how does demand pull cause inflation
- prices in a market are determined by demand and supply and a shift in either will cause price to change
- inflation can therefore be caused by an increase in aggregate demand (AD), total demand for goods and services in the economy
- if any factor which increases AD was to increase, then inflation would increase
how does cost push cause inflation
- whilst an increase in aggregate demand can push prices up, a decrease in aggregate supply may also push prices up
- when businesses find their costs have risen, they will put up prices to maintain their profit margins
- this can be caused by any factor which decreases AS
how does growth of money supply cause inflation
- another potential cause of inflation is there being too much money in the economy
- if people have access to money they will want to spend it but if there is no increase in the amount of goods and services supplied, then prices will have to rise
- the government can also increase the amount of money that they print and decisions to increase government borrowing can also increase the money supply
what is the effect of inflation on consumers
- if people’s incomes do not rise with inflation then they will have less to spend , which could cause a fall in living standards
- those who are in debt will be able to pay it off at a price which is of cheaper value, but those who are owed money lose because the money they get back is of cheaper
value - consumers who have saved will lose out as their money is worth less
- inflation has psychological effects on consumers: because prices are rising, they may feel less well-off, even if their income is rising in line with inflation, and so this may cause them to decrease their spending
