2.1 Measures of Economic Performance Flashcards
Define nominal value
The value of an economic variable based on current prices, taking no account of changing prices of inflation
Define real value
The value of an economic variable, taking account of inflation
How do you calculate a price index to account for inflation? (Regarding GDP)
(Nominal GDP/ Real GDP) x 100
How do you calculate a percentage change of an economic variable?
(Change/ Original) x 100
Define the term index number
A device for comparing the value of a variable in one period or location with a base observation
Define potential economic growth
An expansion in the productive capacity of the economy
Define gross domestic product
The total value of goods and services produced in an economy in a given time period.
What 3 factors of GDP are all assumed to equal the same thing?
1) Total value of goods + services produced
2) Total expenditure
3) Total income earnt
Define gross national income (formally known as GNP)
Domestic GDP plus net income from abroad
Define actual economic growth
The rate of growth of GDP in a period
Why is actual growth not always equal to potential growth?
Because the economy is not always operating at full capacity, due to most economies going through the business cycle
Define the term business cycle
A phenomenon whereby GDP fluctuates around its underlying trend, following a regular pattern of booms, downturns, busts and recoveries
When is it preferred to use GNI instead of GDP, and why?
When measuring standard of living because it reflects the incomes of the residents
Define GNI per capita
The average level of GNI per head of the population
What are the 4 main limitations of using GDP or GNI to compare living standards over time?
1) Inequality in income distributions
2) The informal sector and accuracy of data
3) Exchange rate problems
4) Social indicators
Explain the issues of the informal sector and accuracy of data
- Given some data collection agencies may be more reliable than others, not all international data may be reliable
- Especially in the informal sector, many transactions go unrecorded, so will not be included in GNI data
Explain the issues of exchange rates when using GDP or GNI
GNP and GNI tends to be turned into US dollars for international comparison.
However, the exchange rates may not be a reliable indicator of purchasing power of incomes, given exchange rates can either be affected by govt policies or by prices of internationally traded goods.
How have the UN combatted the issue of exchange rates when using GDP or GNI?
By adjusting GNI figures to the purchasing power parity of each country
What is purchasing power parity?
A theory that measures prices at different locations using a common good to contrast the real purchasing power between different currencies.
Describe the issue of a lack of social indicators in GNI or GDP
GNI and GDP refer to the value of resources in an economy, but do not consider education levels, access to healthcare etc, which are social indicators of standard of living
Describe the trends of rates of growth of countries between 1950 and 1960
Countries in North America, Western Europe and Japan were early developers, whilst Sub-Saharan Africa and Latin America were later in development
How does the trends of rate of growth in countries change between 1960 and 1980?
The gap between countries begin to widen, where Nepal and India had very low growth.
Latin America had diverse growth, whilst East Asian countries like Korea and Malaysia began to catch up to early developers.
Describe the general trends of growth of countries between 1990s and 2012
International growth on average was low due to the financial crash of 2008.
Sub-Saharan Africa had very low growth, whilst China experienced nearly 10% growth per annum.
How may gross national happiness be calculated? (2)
- By adjusting GNI to only include variables that positively contribute to economic wellbeing
- To ask people whether they are happy or not
How did the UK try and measure levels of happiness in 2010?
The ONS launched its ‘Measuring National Wellbeing Programme’ in 2010.
It used indicators such as personal wellbeing, relationships, health, education and the environment.
Is there likely to be a relationship between real incomes and happiness?
The relationship is positive, but not likely to be very close, given that people’s subjective perception of happiness will be related to a whole host of different factors.
How is inflation in the UK calculated?
Using the consumer price index (CPI)
Define the consumer price index
A measure of the general level of prices in the UK, the rate of change of which has been used as the government’s target of inflation since Jan 2004.
How is CPI calculated?
It measures the general level of prices, not the rate of change of prices
What is an alternative measure of the rate of inflation that is not CPI?
The retail price index (RPI)
Describe what the RPI is and how it is different from the CPI
The RPI measures the average level of prices in the UK.
The RPI excludes interest on mortgage repayments, as well as pensioner households and the highest income earners, whereas CPI does not.
What is the target rate of inflation in the UK?
2% +/- 1%
