POSITIVE EXTERNALITIES IN PRODUCTION AND CONSUMPTION Flashcards
A POSITIVE EXTERNALITY in consumption IS A
Benefit to 3rd parties as a result of actions of consumers
a 3rd party in positive xdternality of consumption is
econ agent not involved inte h transaction or activity taking place at all but is still afeected by it
give 3 examples of positive externalities
health care
education
excersise/health eating
explain why health care is a +ve externality
if your vacc against the flu
the 3rd party that benefots are the people in sopciety as gopt less chance of getting the flu
explain why excersise/healthy eating is a +ve externaity
through consumers doing this
3rd party that ebenfit is employers as workers have a higher productivity so work more often and produce more meaning more rev for firms
in a positive externality of consumption explain msb and mpb and why
msb greater than mpb
due tp external beenfits becoming +ve in the sb equation making sb higher than private pebengits
what curve ,oves in +ve externlaity of consumption
d curve
msb=mpb=d
draw graph
y axis - price/cost/benefits
x axis - quantity
msb hihger than mpb
q1 and p1 at mpb = s
q* p* at social optimum of msb = msc
shade in welfare loss pointing towards social optimum
in +ve externality of consumption where does the freemkt allocatre scarce resources
private optimum
mpb=mpc
where does society want aosr in +ve external of consumption
where msb=msc
the social optimum
where is the reallocation of scarce resources shown by on the graph = 1 point
and explain it = 2 points
q1-q*
theres an underconsumption and underproduction
therefore there’s a MAOSR and alocative inefficiency meaning theres a welfare loss
explain why a wl caused in +ve external of consumption
3 points
mention priv optimum quantity and what this tells us about benefits and costs
@q1 social benefits are higher than sc
so we have more beenfits than losses
therfore by not producing extra units from q1-q* we loose out as a society on potential extra social benefit
sum up why weve got a welfare loss and losse out on potential social benefit
units q1-q*
sb>sc
so by not producing up to Q*
we loose out on net social benefit
analys +ve external of consumption
consumers ignoring ..
3 partially/semi fat paragraphs
consuemrs are ignoring the full sb of actions and only considering pb due to self interest
therfore mkt allocates resources at priv optimum meanignthers an underconsumptiona n production compared to what we want as society (social optimum)
therfore theres allcoative inefficinec anda welfare loss as too few resources are being allcoated to this mkt than socially desirable
what are +ve externalities in production
beenfits to 3rd parties as a result of actions of producers
