section 3 Flashcards
how do we measure size of the economy
through national income (gdp)
what is uks gdp
£2 trillion
what is gdp
the total value of good and services produced within the boundaries of an economy in a given time (usually one year)
three ways to measure gdp
output measure
expenditure measure
income measure
output measure
this is the total value of the goods and services produced by all sectors of the economy: agriculture, manufacturing, energy, construction, the service sector and government
expenditure measure
the value of the goods and services bought by households and by government, investment and the value of exports minus imports
income measure
the value of income generated mostly in terms of profits and wages
how to measure economic growth
measured by % change in real gdp over a period of time (usually 3 month / quarter or a year)
formula to convert nominal gdp to real gdp
nominal gdp % change - inflation %
recession
two consecutive quarters of negative real gdp
real gdp per capita and formula
real gdp per person indicating living standards
real gdp / population
change in real gdp per capita formula
nominal gdp % - rate of inflation % - change in population %
short run economic growth
increase in real output mainly caused by increases in ad
the impact upon output and the price level will depend upon how close the economy is to full capacity
the closer to full capacity the steeper the sras curve
things that impact sras
cost of production
aggregate demand
long run economic growth
an increase in productive capacity of an economy (outward shift of lras)
improving the supply side of the economy is essential for long run economic growth
difference between ppf and lras curve
both shifting outwards represent an increase in productive capacity of an economy
lras- normal (sustainable) capacity
ppf- maximum productive capacity
what causes short run economic growth versus long run economic growth
sras - aggregate demand
lras - aggregate supply
the economic cycle
short run fluctuations in economic activity and long run trend rate of growth - changes in actual gdp
these fluctuations represent changes in short run economic growth - mainly caused by changes in ad (but sometimes by as)
different stages of the economic cycle
recession; 2 consecutives quarters of negative real gdp
peak; top of the cycle
trough; the bottom of the cycle
demand side factors that cause a change in the economic cycle
consumer business confidence
changes in wealth factors (house prices or stock market)
government policy / change in fiscal policy
central bank policy / changes in monetary policy (interest rates)
globalisation
exchange rate shocks
demand side shocks
the accelerator and the multiplier
excessive growth in debt and credit
supply side factors that cause a change in the economic cycle
changes in costs of production
supply side shocks (increases in the price of oil / energy)
output gap
the difference between the actual output and potential output
positive; real gdp > trend gdp
negative; real gdp < trend gdp
macroeconomic disequilibrium
ad > as
as > ad
main macro objectives during boom
gdp up
unemployment down
inflation up
balance of trade down
main macro objectives during bust
gdp down
unemployment up
inflation down
balance of trade up
benefits of economic growth
higher living standards / fall in poverty, fiscal dividend, long run growth helps control inflation, higher investment
downsides of economic growth
trade off between short term growth and inflation
new growth not shared equally
environmental impacts
policies to promote economic growth
monetary policies (short run)
fiscal policy (short run and long run)
supply side policies (long run)
monetary policies
bank rate
exchange rates
money supply and credit
fiscal policies
taxation
government spending
borrowing
supply side policies
industrial policy measures
financial and capital market measure
labour market measures
low interest rates impact on cyclical instability
low interest rates increase borrowing
borrowing up means investment up means ad up
but at some point borrowing has to be paid so consumption down so ad down
some may borrow too much and default on repayments
leading to cyclical instability ( or crisis like gfc 2008)
