Section 8 - Measuring Economic Growth Flashcards
What are the 4 main macroeconomic indicators?
>The 4 main macroeconomic indicators which can be used to measure a country’s economic performance are:
1. The rate of economic growth.
2. The rate of inflation.
3. The level of unemployment.
4. The state of the balance of payments.
>Governments use these indicators to monitor how the economy is doing.
How can economic growth be measured?
>Economic growth can be measured by the change in national output of a period of time.
>Output can be measured in 2 ways:
1. Volume = adding up the quantity of goods and services produced in one year.
2. Value = calculating the value (£billions) of all the goods and services produced in one year.
>National output is usually measured by value - this is called the Gross Domestic Product (GDP).
National output - definition
>All the goods and services produced by a country.
GDP
>GDP is a measure of economic growth - it is all the goods and services produced by a country (national output).
>GDP can also be calculated by adding up the total amount of national expenditure in a year, or by adding up the total amount of national income earned in a year.
>This means that, in theory, national output = national expenditure = national income.
Economic growth - definition
>The rate of economic growth is the speed at which the national output grows over a period of time.
Economic growth - useful terms
>Over the course of several years, the speed of economic growth is not usually constant. Here are a few useful terms:
- Long periods of high economic growth rates are often called booms.
- If there’s negative economic growth for two consecutive quarters this is called a recession.
- A long recession is often referred to as a slump.
- An economic depression is worse than a recession - it’s sustained economic downturn which lasts for a long period of time (e.g. several years).
What does a slow down in economic growth mean?
>The rate of economic growth is still rising just more slowly.
Changes in GDP
>Over one year, a country’s GDP may increase or decrease.
>This measures the change in the amount of goods and services produced between one year and the next.
>Change can be shown in 2 ways:
1. Value (£billions).
2. Percentage.
Measuring economic growth over time
>As a percentage.
>Change in GDP divided by original GDP x 100.
GDP and inflation
>Some GDP growth may be due to prices rising (inflation).
>Nominal GDP is the name given to a GDP figure that hasn’t been adjusted for inflation.
>This figure is misleading - it’ll give the impression GDP is higher than it is.
>Economist remove the effect of inflation to find what’s called real GDP.
>E.g. 4% increase in nominal GDP when inflation was 3% means real GDP only rose by 1%. The other 3% was due to rising prices.
What can you use to compare standards of living
- GDP per capita.
- Gross National Income (GNI) per captia.
- Gross National Product (GNP) per capita.
- Purchasing Power Parity (PPP).
GDP per capita
>In theory, the higher the GDP per capita, the higher the standard of living in a country.
>Total GDP/population size.
>National output per person.
GNI
>Gross National Income.
>GNI is the GDP plus net income from abroad - this net income is any income earned by a country on investments and other assets owned abroad, minus any income earned by foreigners or investments domestically.
>GNP per capita is used to compare living standards between different countries.
GNP
>Gross National Product.
>GNP it the total output of the citizens of a country, whether or not they’re resident in that country.
>GNP per capita is used to compare standards of living.
Boom - definition
>Long periods of high economic growth rates.
Recession - definition
>If there’s negative economic growth for two consecutive quarters.
Slump - definition
>A long recession.
Economic depression - definition
>Sustained economic downturn which lasts for a long period of time (e.g. several years).
PPP
>Purchasing Power Parity is used in comparisons of living standards.
>Purchasing power is the real value of an amount of money in terms of what you can actually buy with is.
>Varies between countries, in less developed ones $1 will buy more.
>Using PPP in comparisons of countries’ living standards involves adjusting the GDP per capita figures to take into account the differences in purchasing power in those countries, with the results usually expressed in US dollars.
>This makes for a more accurate and easier comparison.
What problem does PPP overcome?
>When using GDP/GNI/GNP per capita to compare living standards in countries that use different currencies, the exchange rate might not reflect the true worth of the two currencies - so comparing GDP per capita in this way might not give an accurate picture.
>To overcome this problem, comparisons are usually carried out using the principle of PPP.
GDP and GDP per capita - conclusions
>Used to compare the economic performance and standards of living in different countries.
>A high GDP would suggest a country’s economic performance is strong.
>A high GDP per capita suggests that a country’s standard of living is high.
>Limitations.
What may GDP and GDP per capita not take into account?
>The extent of the hidden economy - economic activity that doesn’t appear in official figures.
>Public spending - some governments provide more benefits, such as unemployment benefits or free health care, than others. E.g. 2 countries may have similar GDP per capita figures but one country might spend much more money per person on providing befits that improve the standard of living.
>The extent of income inequality. 2 countries may have similar GDP per capita, but the distribution of that income between rich and poor may be very different.
>Other differences in the standard of living between countries, e.g. the no. of hours workers have to work per week, working conditions, the level of damage to the environment, and different spending needs (e.g. cold countries spend more income on heating to achieve the same level of comfort that exists in warm countries).
Index numbers
>Index numbers represent percentage changes.
>They are useful for making comparisons over a period of time.
>The first year is called the base year - the index number for this year is set at 100.
>Calculate: value for current period divided by value for base period x 100.
Why use index numbers?
>Allow for quick and easy data comparisons.
>Compare rate of change with very different sets of data e.g. £ and $.
>Less ugly.
Cons of index numbers
>Tell us rate of increase but can’t compare actual prices.
