what is tragedy of commons
when individuals act independently according to their private incentives to enjoy the benefit of the common resource
each individual’s going is to maximise their private benefit from common resource BY using more of the common resource
they end up depleting shared resources, such as fisheries or pastureland.
even though individuals recognise the common resource is being exploited (may not be enough fish in the sea), why wont they stop using it?
someone else will use it and enjoy its benefit if they do not, so the individual will continue using it
e. g. even though i know sending too many cows will use up the land, i also know if i don’t use it, someone else will use it
e. g. in their interests to use as much as they can so they can maximise their profit in the present even though it may be detrimental to their business in the future

what is australia more efficient in?
Who has the absolute advantage?
Is australia more productive in one area?
what is the opportunity cost?
If australia has 15000 hours of labour, then what can australia produce up to?
what can foreign produce up to given they have 48000 hrs of labour
Given australia can produce up to 500 units of beef and 3000 of textile, show on PPC
show foreign opportunity cost of beef
what is the slope
Given foreign can produce up to 800 units of beef and 6000 of textile, show on PPC
show Aus opportunity cost of beef
what is the slope
since Opp cost of beef is 6 units of textile for AUS
and 7.5 for FOR,
what should they do?
what happens in this production change?
more is produced for everyone to consume via more efficient use of resources
