2.1 Measures Of Economic Performance Flashcards
What is economics growth
Economic growth is the rate of change of output. It is an increase in the long term productive potential of country which means there is an increase in the amount of goods and services that a country produces
How is economic growth measured
Typically measured by the percentage change in real GDP per annum. It can also be shown though a shift of the PPF
What is gross domestic product for
The standard measure of output, which allows us to compare countries. It is the total value of goods and services in a country within a year.
GDP is an indicator of the standard of living in a country
What does tot GDP represent
What does GDP per capita represent
Total GDP represents the overall GDP for the country
GDP per capita is the total GDP divided by the number of people in a country
Difference between real GDP and nominal GDP
Real GDP strips out the effects of inflation whilst nominal GDP does not
What is gross national income
The value of goods and services produced by a country over a period of time plus net overseas interest payments for dividends. This means it adds what a country earns from overseas investments and subtract what foreigners earn in a country and send back home
What is 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. The value of all goods produced by citizens of a country’, whether they live in the country or not
Why is it important to use GDP per capita numbers instead of just GDP
When country’s have a difference in population, a difference in total GDP doesn’t necessarily mean a difference in living standards so to make comparisons, GDP per capita is used
If a country’s population and GDP grows, this doesn’t mean standard of living has necessarily increased.
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 compared to one in another country
They provide an alternative to using exchange rates for comparisons of GDP
Why are PPP’s useful
These are useful when comparing countries as it takes into account the cost of living and so will help us compare better living standards.
Why does inaccuracy of data demonstrate a problem of using GDP to compare standard of living
• some countries are inefficient at collecting or calculating data and therefore comparisons less effective
• there is a hidden or black market in which people work without declaring to avoid tax.
• GDP does not take into account home-produced services. (Poor countries farmers may grow their own crops to eat)
• errors in calculating inflation rate
Other problems of using GDP to compare standard of living
Inequalities - 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 is much higher than 50 years ago, but this is not reflected in the price. Therefore, living standards are better off than GDP suggests.
Comparing different currencies - issues over which unit should be used to compare figures. (Usually US dollar)
Spending - some types of expenditure (defence) does not increase SOL but will increase GDP. For example, 1930 UK GDP was higher but SOL wasn’t.
What are the 6 key factors that contribute to national happiness
real GDP per capita
Health
Life expectancy
Having someone to count on
Perceived freedom to make life choices
Freedom from corruption
Generosity
What is the easterlin paradox
Research shows that happiness and income are positively related at lower incomes
People on lower incomes are more happy with an increase in income than people that make higher incomes
What is inflation
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
What is deflation
The fall of prices and indicates a slowdown in the rate of growth of output in the economy which erodes
What is disinflation
A reduction in the rate of inflation. Prices are still rising but not as much
What is the consumer price index
The ONS collects prices in 710 goods and services from 20k shops in 141 locations
All these prices are combined using information on the average household spending pattern to produce an overall price index
It takes into account how much is spent on each item so they are weighted I.e spend more on petrol than postage stamps so increase in petrol will have an overall bigger impact on inflation
Limitations of the CPI
• impossible to take into account every good that is sold so therefore it is not totally representative
• does not include the price of housing and housing has tended to rise more than other goods
• more recent than the RPI, therefore, it is difficult to make comparisons with historical data.
Why is it argued that all inflation indices overestimate inflation
They don’t take into account the fact that goods and services have improved in quality, and so obviously will be more expensive.
What is the retail price index
Very similar to CPI, but differences between data included and how calculated
• RPI takes into account housing costs such as mortgage and interest payments and council tax, whereas CPI does not
• RPI excludes the top 4% of income earners and low income pensioners as they are not ‘average households’
RPI is not longer considered as the best method and has had its national statistic status removed
What is demand pull (causes of 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 AD.
If any factor which increases AD was to increase, then inflation would increase
What is cost push (causes of inflation)
Whilst an increase in aggregate demand can push prices up, a decrease inn aggregate supply may also push prices up
When businesses find their costs have risen, they will put up prices to maintain their profit margins.
What is growth of money supply (causes of 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.
