2.1 Measures Of Economic Performance Flashcards
Economic growth
The increase in the long term productive potential of the country
measured through % change in real GDP per annum or shift in PPF
Sustainable economic growth
Economic growth that meets the needs of today without compromising the needs of future generations
Real GDP
The total value of goods and services produced in a country within a year adjusted for inflation (not adjusted = nominal)
Total GDP
Overall GDP for the country
GDP per capita
The total GDP divided by the number of people in a country
GDP indicates?
Standard of living in a country
GDP per capita growth
GDP per capita increases if national output grows faster than population over a given time period as there are more goods and services to enjoy per person
Real values
Volume of national income
Nominal values
Value of national income
Value equation
volume x current price level
GNI
The value of goods and services produced by a country over a period time plus net overseas interest payments and dividends.
GNP
The value of goods and services over a period of time through labour or property supplied by citizens both domestically and overseas
Comparison of growth overtime
Growth figures over a set period of time can be compared against similar countries to see whether the country has done well or not
Can compare standard of living / economic welfare
Comparisons of growth between countries
When countries have a difference in population, a different in total GDP per capita so GDP per capita is used
Purchasing Power Parities
An exchange rate of one currency for another which compares how much a basket go goods in the country costs compared to another country
PPP advantage
Takes into account cost of living when comparing countries
Informal economy
Estimated to take up 10-15% of GDP
Problems of GDP comparing standard go living
Inaccuracy of data - some countries may be inefficient at collecting/calculating data, Informal economy
Errors in calculating inflation rate
Doesn’t take into account quality of goods and services
Issue go which unit should be used to compare different currencies/ figures
Some types of expenditure, e.g defence, does not increase standard of living but may increase GDP
National happiness
Qualitative measure of progress or development which includes factors such as sustainable and equitable socio-economic development
Easterlin Paradox
An increase in consumption of material goods will increase happiness if basic needs aren’t met however, once these needs are met, an increase in consumption won’t increase long term happiness
Actual growth
Where aggregate demand is equal to aggregate supply
Potential growth
Where aggregate supply is operating at full capacity (where all resources are fully employed)
Inflation
The general increase of prices in the economy which erodes purchasing power of money
Deflation
The fall of prices and indicates a slowdown in the rate of growth of output in the economy
Disinflation
A reduction in the rate in of inflation
CPI
ONS collects prices on 710 goods and serves from 20000 shops in 141 locations and prices are updated every month
New items added to list every year
Prices are combined using average household spending pattern to produce an overall price index
Average household spending
Worked out through Living costs and food survey, where 5500 families keep diaries of what they spend fortnightly
Takes into account how much is spent through each item so they are weighted
Limitations of CPI
Not totally representative as it is impossible for the figure to take into account every single good that is sold in a country
Does not include price of housing which tends to increase in price more than other goods
Difficult to make comparisons with historical data as it is very recent
Overestimates inflation as it doesn’t take into account that goods have improved in quality
Cost push inflation
A general rise in the price level because of increasing COP (decrease in SRAS), as firms will put prices up to maintain profit margin. This shows a decrease in real GDP and a fall in productive capacity
Demand pull inflation
When aggregate demand increases at a faster rate than aggregate supply. AD increases, prices increase. Shows an increase in real GDP but at an unsustainable rate
