section 2 (as) Flashcards
aggregate supply
the level of real national output that firms are prepared to supply at different price levels
difference between sras and lras
in sras, the labour supply is limited which limits the amount that can be produced
in lras every factor if production is infinite
short run aggregate supply
when at least one factor of production is fixed (usually capital or labour)
long run aggregate supply
all factors of production can be varied
reflects the normal productive capacity of the economy (maximum sustainable level the economy can produce at)
equivalent to full employment, and all factors of production being fully and effiently used (same as ppf)
what causes the sras to shift
changes in cost of productive shift the sras due to change in incentive to supply depending on price level
typical costs of production examples
raw materials
commodities
labour costs (wages)
energy prices (oil)
interest rates
subsidies
indirect taxes
business rates
productivity
supply side shocks
unexpected events which impact the supply side of the economy (in short run usually means unexpected change in costs of production
supply side shock examples
covid 19
ukranian war
determinants of long-run aggregate supply
quantity of factors of production
quality of factors of production
mobility of factors of production
technology
investment (on physical and human capital)
productivity
institutional structure of the economy
economic incentives
how do quality and quantity of factors of production impact lras with examples
quantity up - production up - lras up
(e.g. increased immigration)
quality up - productivity up - lras up
(e.g. better education and training)
factor mobility
the ease with which factors of production can be used for other purposes
in labour:
occupational mobility (match of jobs and skills)
geographic mobility (match of where people and jobs are)
economic incentives that can impact lras
increase lras by incentivising people to work:
lowering welfare benefits
reducing income tax
increasing the minimum wage
increase lras by incentivising firms to be productive:
lowering coorperation tax
subsidies
support enterprise
