This document discusses government subsidies provided to producers and consumers. It defines subsidies as financial or other support from the government. Examples of subsidies for producers include biofuel subsidies for farmers and subsidies for wind farm investment. Examples of subsidies for consumers include food/fuel subsidies and child care for working families. The document then examines how subsidies work through diagrams, showing how they lead to a lower equilibrium price and higher equilibrium quantity. It also justifies why governments introduce subsidies and evaluates their impacts through concepts like cost-benefit analysis.

6. JusEficaEons
for
Subsidies
for
Producers
Subsidies
are
a
form
of
government
intervenLon.
They
are
introduced
for
a
number
of
economic,
social
&
poliEcal
reasons
Help
poorer
families
e.g.
food
and
child
care
costs
Encourage
output
and
investment
in
fledgling
sectors
Protect
jobs
in
loss-­‐
making
industries
e.g.
hit
by
recession
Make
some
health
care
treatments
more
affordable
Reduce
the
cost
of
training
&
employing
workers
Achieve
a
more
equitable
income
distribuLon
Reduce
some
of
the
external
costs
of
transport
Encourage
arts
and
other
cultural
services

8. Some
EvaluaEon
Arguments
when
Assessing
Subsidies
• Will
they
achieve
the
desired
sLmulus
to
demand
/
consumpLon?
• Is
a
subsidy
sufficient?
Might
other
incenLves
be
needed?
Are
the
subsidies
effecLve
in
meeLng
their
aims?
• Subsidies
for
investment
and
research
can
bring
posiLve
spillovers
• But
firms
may
become
dependent
on
state
aid
/
financial
assistance
Will
a
subsidy
affect
producLvity
/
efficiency?
• Is
a
subsidy
part
self-­‐financing?
Will
it
create
more
tax
revenue?
• Or
does
a
subsidy
create
an
expensive
extra
burden
for
taxpayers?
How
much
does
the
subsidy
cost
and
who
benefits?
• For
example
–
do
more
people
find
work
with
child
care
subsidies?
• Or
does
a
subsidy
lead
to
undesired
/
unintended
consequences?
Does
the
subsidy
help
to
correct
a
market
failure?

9. Cost
Benefit
Analysis
• Cost
benefit
analysis
is
a
process
used
to
measure
the
esLmated
net
social
rate
of
return
from
an
investment
project.
• When
governments
are
deciding
how
much
to
spend
on
public
goods,
they
might
use
a
cost-­‐benefit
approach
to
aid
them
• A
typical
cost
benefit
analysis
involved
the
following
process:
1. Set
the
key
objecEves
for
the
project
2. Set
project
decision
criteria
i.e.
an
acceptable
benefit
to
cost
raEo
3. IdenLfy
and
value
the
private
&
external
costs
of
the
project
4. IdenLfy
and
value
the
private
&
external
benefits
of
the
project
5. Consider
possible
distribuEonal
effects
e.g.
on
inequality
6. Discount
annual
value
of
benefits
that
will
happen
in
the
future
7. Adjust
for
various
risks
and
uncertainEes
8. Consider
the
unvalued
/
non-­‐moneEzed
costs
and
benefits
9. Measure
the
expected
net
social
return
from
the
project
10. Compare
with
expected
net
social
returns
from
other
projects
i.e.
the
opportunity
cost
of
£billion
invested
in
a
project

10. EvaluaEon:
Problems
with
Cost
Benefit
Analysis
Assigning
monetary
values
• Some
aspects
of
a
project
can
be
assigned
a
monetary
value
• Time
savings
e.g.
For
passengers
and
businesses
• OperaLng
costs
of
the
project
• Value
of
carbon
emissions
e.g.
Lower
CO2
from
less
car
use
• Risk
of
death
or
injury
• Other
variables
are
much
harder
to
assign
values
• Bio-­‐diversity
• Water
quality
• Air
quality
• Heritage
• Social
inclusion
/
accessibility
UncertainEes
and
Risks
• There
are
uncertainLes
involved
in
major
projects
with
long
construcLon
Lmes
+
operaLng
life
that
can
last
decades
• Forecast
errors
for
passenger
numbers
in
different
modes
of
transport
• UncertainLes
about
populaLon
growth
• UncertainLes
about
future
operaLng
costs
(including
energy
prices)
• Future
business
growth
/
types
of
businesses
/
impact
of
new
technologies
Supporters
of
major
projects
may
suffer
from
opLmism
bias
when
