define GDP
the value of total output produced in an economy over a period of time.
define GNI
the value of total output produced in an economy over a period of time and net income from abroad taken into account
state the equation linking GDP and GNI
GNI = GDP + net income from abroad
state 3 ways in which GDP can be measured
- Income: Wages + Rent + Interest + Profit
- Output: sum of 1st, 2nd, 3rd sectors’ outputs
- Expenditure: C + I + G + (X – M)
give and explain the equation for GDP using the expenditure approach
C + I + G + (X – M)
GDP = Consumption (C) + Investment (I) + Government spending (G) + Exports (X) - Imports (M)
what are real GDP and GNI?
Real GDP and GNI is the value of total output produced in an economy over a one year period - and adjusted for inflation
give equation for real GDP
real GDP= nominal GDP/GDP deflator x 100
give the equation for real GDP per capita
Real GDP per capita = Real GDP / the population
define and explain purchasing power parity
a conversion factor applied to GDP and GNI
the rates of currency conversion that equalize the purchasing power of different currencies by eliminating the differences in price levels between countries
The aim of PPP is to help make a more accurate standard of living comparison between countries where goods/services cost different amounts
give a theoretical example of PPP
If a basket of goods costs $150 in Vietnam (once the currency has been converted) and the same basket of goods costs $450 in the USA, the purchasing power parity would be 1:3
It seems like the cost of living is much higher in the USA
However, if the USA’s GNI/capita is more than three times higher than the GNI/capita of Vietnam, it could be argued the USA has better standards of living
Conversely, if the GNI/capita in the USA was less than three times that of Vietnam, it could be argued that Vietnamese citizens enjoy a higher standard of living as they spend less income to acquire the same goods/services

give 3 reasons why national income statistics are useful for making comparisons between countries
- They provide insights into the effectiveness of government policies
- They allow judgments to be made about the relative wealth and standard of living within each country
- They allow comparisons to be made over the same or different time periods
why is real GDP a better comparison than nominal GDP?
One country may have a much higher rate of economic growth, but also a much higher rate of inflation.
why does real GDP per capita provide better information than real GDP?
it takes population differences into account
compare GNI and GDP
Using real GNI/capita is a more realistic metric for analysing the income available per person than GDP/capita
Limitations of Using GDP data to Compare Living Standards Between Countries and over time
- Lack of information provided on inequality
- Quality of goods/services
- Does not include unpaid/voluntary work
- Environmental factors (creation of externalities)
give 3 other ways in which national living conditions can be measured
The OECD Better Life Index
The Happiness Index
The Happy Planet Index
3 other ways of measuring national living standards
The OECD Better Life Index
The Happiness Index
The Happy Planet Index
happy planet index
wellbeing x life expectancy / ecological footprint
define aggregate demand
the total level of planned spending in the economy by consumers (C), firms (I), government (G), and foreigners (X-M) over a period of time (usually one year) at different price levels
define aggregate supply
the total planned production at different price levels.
state the equation for AD
AD= C + I + G + (X-M)
C
consumption
I
investment
G
government expenditure
X
exports
M
imports
(X-M)
net exports
draw an aggregate demand curve
flashcard 1
what do movements along the AD curve show?
as price level rises, the level of Real GDP falls and vice versa
what are shifts in the AD curve caused by?
changes in any of the AD components (C, I, G, (X-M), ceteris paribus
Why does the AD curve slope downwards? [3]
- The income effect; at a lower PL, consumers are likely to have higher disposable income and therefore spend more.
- The substitution effect; lower PL in the UK= UK goods will become relatively more competitive, leading to higher exports. Exports is a component of AD so AD will be higher.
- Wealth effect; At a lower price level, interest rates usually fall, and this causes higher AD.
state/explain the 6 determinants of C as an AD component
- consumer confidence
- interest rates
- wealth
- income taxes
- level of household indebtedness
- expectations of future PL
explain how consumer confidence affects AD
A boost in consumer confidence increases aggregate demand and a drop in consumer confidence decreases aggregate demand.
explain how interest rates affect AD
higher IR:
- becomes more “expensive” to borrow money
- consumer spending/investment fall
- AD falls
state/explain the 5 determinants of I as an AD component
- interest rates
- business confidence
- technology
- business taxes
- level of corporate indebtedness
define an interest rate
the amount a lender charges a borrower . it is a percentage of the principal (the amount loaned)
state/explain the 2 determinants of G as an AD component
- political priorities (eg. subsidising education, green companies)
- economic priorities (eg. reducing inflation)
state the 3 determinants of X-M as an AD component
- income of trading partners
- exchange rates
- trade policies
explain income of trading partners as an AD determinant
- increasing the incomes of our closest trading partners means those people would buy more of our stuff, so our exports would increase
- AD increases
explain exchange rates as an AD determinant
an increase in the exchange rate will tend to reduce AD as exports will fall and imports increase.
define short run aggregate supply
the short run is the time period where factor costs are fixed (ie the unit cost of land, labour, capital and enterprise are fixed).
state 5 examples of changes in FOPs
- technology
- skills
- migration
- wage settlements
- commodity prices
describe how indirect taxes would affect the SRAS curve
an effect similar to a rise in production costs (curve will shift left)
state the 2 determinants of the SRAS curve
- costs of FOPs
- indirect taxes
monetarist/new classical view of the LRAS curve (flashcard 3)
LRAS inelastic as wages/prices flexible due to price mechanism:
- all those willing and able to get a job at the WR will have one
- any unemployment is voluntary
SO output will always be at full employment independent of the PL
Keynesian view of the LRAS curve (flashcard 4)
LRAS elastic in long-term – the economy can be below full capacity for a long time unless supply-side initiatives (eg educational changes) are taken
Describe a negative output gap (flashcard 5), or deflationary/recessionary gap:
- actual output (real GDP) is lower than potential output (Yf)
- caused by decrease in AD
describe a positive output gap (flashcard 5), or inflationary gap
- actual output (real GDP) is greater than potential output (Yf)
- caused by increase in AD
state 4 possible causes of shifts in the AS curve over the long run
- changes in the quantity/quality of FOPs
- improvements in technology
- increases in efficiency
- changes in institutions
describe a readjustment to equilibrium in the monetarist/classical model after a drop in AD
- market is at an equilibrium at P1F1
- AD falls from AD1 to AD2. causing:
- P1 to fall to P2
- Yf to fall to Y2
- negative output gap
- demand for labour falls from D1 to D2
- Price mechanism ensures new equilibrium at W2Q2
- lower wages mean lower FOPs, increasing SRAS so curve shifts to right
- new equilibrium found at P3Yf
describe equilibrium in a Keynesian model
- there will be a persistence of deflationary/recessionary gaps: the equilibrium level of output may not equal the full employment level of output
state the assumptions behind the Keynesian model
- wages are ‘sticky downwards’ so workers may refuse lower wages due to trade unions, minimum wage laws, money illusion.
- price mechanism will not work (govt required to take action)
define the money illusion
people think in nominal terms
state the assumptions behind the classical model
- short run unemployment can occur but is a temporary phenomenon; wages are flexible and so will fall, and the labour market will move back into equilibrium
- long run unemployment will be ‘voluntary’
Define unemployment
people above the age of 16, who are able, available and willing to work at the going wage but cannot find a job despite an active search for work
define the economically active population
employed people + unemployed people
give the equation for unemployment rate
numbers unemployed/economically active population x 100
what is the activity/participation rate?
proportion of working age population that are (potentially) active, so either employed or unemployed
what is the inactivity rate?
the percentage of the population of working age that is out of the labour force.
what is the labour force?
the active working age population (16-64yo) that are either in work or able to work and actively seeking work
give a flow diagram for population
population -> population of working age -> labour force/out of labour force (inactive) ->employed/unemployed
define unemployment rate
percentage of the labour force that is not working.
state 2 difficulties of measuring unemployment
- Hidden unemployment, including discouraged workers and underemployment
- average ignores disparities
hidden unemployment
people who are jobless, but official unemployment figures do not include them.
- eg, people who have stopped looking for a job and people who work less than they want to
discouraged workers
people that would like to work and have previously been seeking employment, but have since stopped because they could not find a job.
underemployment
- part time work; where workers would prefer to work more hours but cannot get them
- workers working below their skill levels
economy may be working inside PPC despite low headline unemployment figures
average ignores disparities
the unemployment rate is only an average so does not account for disparities in age, gender, ethnicity and region. For instance, youth unemployement tends to be higher as well as the unemployment rate amoungst ethnic minority groups.
give a pro and a con of unemployment benefits
pro: can make labour market more efficient by enabling better ‘matching’
con: less incentive to find work
what is youth unemployment?
percentage of labour force between 15 and 24 that is unemployed
give equation for youth unemployment rate
no of 15-24yo unemployed/economically active 15-24yo x 100
why is youth unemployment unreliable?
there is an inevitable exaggeration in youth unemployment rates as the activity rate (denominator) is smaller than for the whole population (students are inactive)
what can we use instead of youth unemployment?
NEETs (not in employment, education or training)
state 5 types of unemployment
- classical/real wage
- demand deficient/cyclical
- structural
- seasonal
- frictional
describe the causes of classical or real wage unemployment
caused by real wages being forced above the equilibrium wage rate by actions of:
- government (eg minimum wage laws)
- trade unions
describe how demand deficient/cyclical unemployment happens in the classical view
- AD falls
- causing a NOG
- derived demand for labour falls
- in the short run, wage rate remains fixed; Qs of labour remains at Q1 but the Qd of labour falls to Q2
(wages then fall and employment restored as SRAS shifts right)
assumptions behind classical unemployment theory
- short run unemployment can occur but is a temporary phenomenon; wages are flexible and so will fall, and the labour market will move back into equilibrium
- long run unemployment will be ‘voluntary’
causes of demand deficient/cyclical unemployment
- general lack of AD in the economy
how can demand deficient/cyclical unemployment be fixed? (according to Keynes)
by pushing AD back up, ie through lower interest rates, lower taxes and increased govt spending
describe how demand deficient/cyclical unemployment happens with a diagram in Keynesian view
- AD falls from AD1 to AD2, causing:
- new equilibrium at P2Y2
- NOG - Derived demand for labour falls to D2
- Wage rate stays the same (W1)
- Qs>Qd = unemployment
what did Keynes argue about falling wages?
he argued that if wages fell and workers accepted them, that AD would fall even further, worsening unemployment
what is structural unemployment?
unemployment caused by the decline of industries and the inability of former employees to move into jobs being created in new industries.
- the decline of such industries may be caused by automation and ‘offshoring’ due to globalisation
why would structural unemployment persist?
due to occupational and geographic immobility of labour (ie workers don’t have necessary skills for a different job, and they cannot move)
draw a diagram for structural unemployment
flashcards: NB that labellings need to be SPECIFIC FOR A PARTICULAR INDUSTRY
define frictional (or search) unemployment
unemployment caused when people move between jobs. it will inevitably take time to find alternative work, during which period the worker is ‘frictionally’ unemployed
what affects frictional unemployment?
- the quality of the information available for job seekers is crucial to the extent of the seriousness of FU
- the generosity of benefits can also impact upon the time taken
why may frictional unemployment be a good/bad thing?
if it is too short- underemployment
however, if it is too long- this could become long term unemployment
define seasonal unemployment
unemployment caused by the seasonal nature of employment- tourism, construction, agriculture, skiing, sports, beach lifeguards etc
what is the macroeconomic objective relating to unemployment?
low unemployment
what is the macroeconomic objective relating to inflation?
low and stable rate of inflation (uk=2%)
define inflation
the sustained rise in the general (or average) level of prices
how do we measure inflation?
by using the consumer price index (CPI)
describe the method for finding the CPI
- a typical basket of goods and services is identified annually (from National Accounts)
- Weights are assigned to items to reflect relative importance, or percentage income. this is changed annually
- monthly price surveys are conducted and used to adjust the index
- changes in the index are used to calculate the inflation rate (% inflation)
what are the limitations of the CPI in measuring inflation?
- the basket used in any country represents the purchasing habits of a ‘typical household’, but this will not be applicable to all people.
- there may be variations in regional rates of inflation within a country
- items are removed or added to be more representative of typical demand; however, this limits the ability of analysts to make comparisons from one period of time to another/international comparisons
- prices may change for a variety of reasons that are not sustained- eg seasonal variations in the prices of food and volatile oil prices may lead to unusual movements in the inflation rate and can be misleading
what is a core rate of inflation?
a measure that uses the information of the consumer price index but excludes food and energy prices
why does the CPI exaggerate inflation?
- substitution effects- the CPI disregards the fact that people tend to switch towards cheaper substitutes as prices rise
- quality improvements are disregarded- sometimes as price increases, you get more value for your money (ie the rise is not just due to inflation)
why is the exaggeration of the CPI significant?
economic agents have to use this measure:
- workers/unions; for base pay demands
- businesses; for base price increases
- governments; to set taxes
give the two causes of inflation
- demand pull inflation
- cost-push inflation
describe demand pull inflation with a diagram
- AD increases from AD1 to AD2
- this causes the general price level to rise, and causes a positive output gap
state the difference between anticipated and unanticipated inflation
anticipated inflation= correctly predicted inflation
unanticipated inflation= where actual inflation catches economic agents by surprise (could be higher OR lower than expected)
why is unanticipated inflation problematic?
as it results in a misallocation of resources (allocative inefficiency) by affecting the price mechanism signal
what could be 4 causes of demand-pull inflation?
demand side:
- cut in interest rates
- increased money supply
- higher wages
- inflation expectations
what could be 4 causes of cost-push inflation?
supply side:
- higher wages
- devaluation/depreciation
- increase in VAT
- inflation expectation
why would cutting interest rates cause an increase in AD?
cheaper to borrow:
- encouraged spending and investing
