2.1 Measures of Economic Performance Flashcards
(92 cards)
Economic Growth
Rate of change of output
Increases in the long term production potential of the country
Increase in amount of goods and services produced by a country
Measured by percentage change in real GDP per annum
Showed through shift of PPF
Gross Domestic Product
Standard measure of output allowing to compare countries
Total value of goods and services produced in a country within a year
Indicator of standard of living in a country
Total GDP
Overall GDP of a country
GDP Per Capita
Total GDP divided by the population of the country
Grows if national output grows faster than population over a given time period
More goods and services to enjoy per person
Real GDP
GDP after the effects of inflation
Nominal GDP
GDP before effects of inflation
Real Values vs Nominal Values
Real is described as volume of national income
Nominal is described as value of national income
Value = Volume * Current Price Level
Value of NI is its monetary value at the prices of the day
Volume is NI adjusted for inflation and expressed as an index number or in money terms
National Income Measures
Gross Domestic Product (GDP)
Gross National Income (GNI)
Gross National Product (GNP)
Gross National Income
Value of goods and services produced by a country over a period of time plus net overseas interest payments and dividends
Adds a country’s net trade (exports - imports)
Affected by profits from oversea businesses and remittances
Increasingly used rather than GDP due to growing size of remittances and aid
Gross National Product
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
Value of all goods produced by citizens of a country whether they live in the country or not
GDP is value of goods produced inside a country whether they citizens or not
Comparisons about growth
Over time
Between countries
Comparisons about growth over time
Changing NI levels show whether the country has grown or shrunk over a period of time
Data compared to similar countries to see if the country has done well or not
Figures make judgements of economic welfare as NI growth leads to rise in living standards
Use real, per capita figures for accurate comparisons
Comparisons about growth between countries
When countries have a difference in population, difference in total GDP does not necessarily mean difference in living standards
=> GDP per capita used
Real GDP needs to be used as GDP can increase simply because of an increase in prices in the country and inflation is different in all countries
Purchasing Power Parities
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
Provide alternative to using exchange rates
Useful when comparison countries as it accounts for cost of living so easier to compare living standards
Big Mac Index
Limitations of using GDP to compare living standards
Inaccuracy of data
Inequalities
Quality of goods and services
Comparing different currencies
Spending
Limitations of using GDP to compare living standards
Inaccuracy of data
Some countries are inefficient at calculating data
Use of black market => GDP underestimated
Does not account for home-produced services
Errors in calculating
Different methods used by countries => making comparisons difficult
Important to take away transfer payments
Limitations of using GDP to compare living standards
Inequalities
Increase in GDP may be due to growth of income of only one group of people
=> Growth in NI may not increase living standards of all
Income distribution changes over time and varies between countries making comparison difficult
Limitations of using GDP to compare living standards
Quality of goods and services
Quality has increased over time but does not reflect in real price
=> Living standards may have increased more than GDP suggesting quality of goods and services has improved significantly
Improved technology allows prices to fall suggesting falling living standards when that is not the case
Limitations of using GDP to compare living standards
Comparing different currencies
Issues over which unit should be used to compare
Usually converted to US dollars due to size of American economy
Some argue PPP should be used to take into account impact of differences in cost of living in different countries
Limitations of using GDP to compare living standards
Spending
Some expenditure does not increase living standards but increases GDP - spending on defence or military
=> Difficult to make comparisons
National Happiness
GDP only measures income but there are other factors affecting welfare such as happiness
National Happiness Factors
Real GDP per capita
Health
Life Expectancy
Having someone to count on
Perceived freedom to make life choices
Freedom from corruption
Generosity
National Wellbeing
Measure of how lives are improving
Factors:
Self-reported health
Relationship status
Employment status
Real Incomes and Subject Happiness Correlation
Happiness and income are positively related at low incomes
High levels of income are not associated with increases in happiness
