Measures of economic performance 2.1 Flashcards
What is GDP
GROSS DOMESTIC PRODUCT it is the standard measure of output which allows us to compare countries. Total value of goods and services produced in a year
Real gdp vs nominal
Real GDP is the GDP adjusted for inflation.
nominal is not adjusted.
Total GDP vs per capita
Total represents the overall GDP for a country
Per capita is the total divided by the population of the country
Gross national income
The value of goods and services produced by a
country over a period of time plus net overseas interest payments and dividends.
Gross national product
The value of goods and services over a period of
time through labour or property supplied by citizens of a country both domestically
(GDP) and overseas.
Advantages of purchasing power parities
They provide an alternative to using exchange rates for comparisons of GDP.
It takes into account the cost of living so it helps us better compare living standards.
What is a 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.
Disadvantages of using GDP to compare living standards for countries
-Inaccuracy of data
Some countries are inefficient at collecting data so comparisons become less effective.
There is a hidden market where people work without declaring their income so GDP is underestimated
-Inequalities
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 national income may not increase living standards everywhere.
-Quality of goods and services
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.
-Comparing different currencies
There are issues over which unit should be used to compare figures
How is national wellbeing measured
They ask 4 key questions about life satisfaction, anxiety, happiness and worthwhileness, where people answer on a scale of 0 “not at all” to 10 “completely”. The report is now updated on a quarterly basis, rather than annually.
Define
Inflation
Deflation
Disinflation
-Inflation is the general increase of prices in the economy which erodes the purchasing power of money. Low inflation is generally considered to be better than high inflation
-Deflation is the fall of prices and indicates a slowdown in the rate of growth of output in the economy.
-Disinflation is a reduction in the rate of inflation i.e. prices are still rising but they are not rising by as much.
How is the Consumer prcice index used to measure inflation
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 carrots.
● 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.
● It takes into account how much is spent on each item so they are weighted i.e. we spend more on petrol than on postage stamps so an increase in petrol will have a bigger impact on the overall rate of inflation.
Whats the problem with using 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 . Similarly, 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.
● Moreover, 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.
● Since the figure is more recent than RPI, it is difficult to make comparisons with historical data. 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 is the Retail price index
The RPI is very similar to the CPI. However, there are some differences between the data included and the way it is calculated.
● 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.
RPI is no longer considered as the best method and has had its national statistic status removed, although the Office for National Statistics still calculates it every month.
What are the 3 causes of inflation
Cost push
Demand pull
Growth of money supply
What is demand pull 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.
What is cost push inflation
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
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.
