Problem of Scarcity

A

Economic Resources = scarce
as ∞ wants+ needs of ppl/businesses in economy
THUS
important to efficiently use resources to max output

Q

1.1.3a
Labour

A

Human input into production process

Recent years = substained expansion in employed labour force
Housewife etc = not labour as productions non-marketed output > not included in GDP

⬆️Q labour = ⬆️education + training + experience

Productivity = output per worker over given period of time
Human capital = quality of labour resources
⬆️ HC = ⬆️investment in education +training + health

Land

A

Natural resource available for production

Some nations endowed with/ NR
THUS
exploit by specialising in extraction/production of resources
E.G North Sea oil/gas

ONLY free = air
AS
consumption by one person doesn’t reduce air for others
Free good = no opportunity cost

Scarce
AS
not enough to satisfy demand of CP

Capital

A

Finance required to operate a business
Investment in goods that can produce other goods in future

E.g = machines , roads , factories , schools

⬆️Capital stock = ⬆️ investment = important in long run
AS
W/o capital , economy cannot produce output ∴ full capacity reached quickly

Q

1.1.4a
Depictions of a PPF

A
  • the PPF line represents maximum productive potential of an economy
  • opportunity cost is when producing more of one good means producing less of another good, steeper the line = more OC
  • economic growth = outward shift due to increase in FOP
  • economic decline = inward shift due to depletion in resources (natural disaster , war = less labour)
  • efficient allocation means point is on curve
  • inefficient allocation means point is inside curve leading to leading to underemployment or misallocation
  • possible means the economy can produce the combination of goods
  • unobtainable means point is outside PPF , economy cannot produce it unless economic growth

Demand Curve influenced by Diminishing Marginal Utility

A

Sloped down as each additional unit provides less utility so at
- higher prices less are bought as consumers aren’t willing to pay high prices for less utility
- lower prices more are bought as the lower price justifies getting less utility per unit.

relationship between PED and total revenue

A
  • Elastic (PED > 1): decrease in price = proportionally larger increase in quantity demanded = increase in total revenue
  • Inelastic (PED < 1): decrease in price = proportionally smaller increase in quantity = decrease in total revenue
  • Unit elastic (PED = 1): change in price = equal percentage change in quantity demanded = no change in total revenue

A
  • cost of production
  • production of other goods
  • weather
  • technology
  • goals of supplier
  • govt legislation
  • tax + subsidies
    -
63
Q

1.2.4b
Reasons why supply curve slopes up

A
  • higher prices means higher profit so firms supply more to sell
  • higher prices means new firms enter market to make more profit and increase supply
  • more supply = rising marginal cost but can be justified by increasing profits

PES formula

A

%🔺Q supplied
———————
%🔺price

66
Q

1.2.5c
Numerical Values of PES

A

Perfectly elastic: PES = ∞ (Producers are willing to supply any quantity at a given price)
Relatively elastic: PES > 1
Unit elastic: PES = 1
Relatively inelastic: 0 < PES < 1
Perfectly inelastic: PES = 0 (Quantity supplied remains constant regardless of price changes)

67
Q

1.2.5d
Factors influencing PES

A
  • time : short term where 1 FOP is fixed ∴firms can’t respond quickly to price changes
  • production time e.g agricultural good take long to make
  • spare capacity e.g can hold more stock ∴ ⬆️versatile to change
  • spare capacity e.g machines
  • FOP readily available?
  • factor immobility e.g transport between counties for capital goods
  • ability to switch production
68
Q

1.2.5e
Short run PES

A

atleast one FOP is fixed

69
Q

1.2.5e
Long run PES

A

all FOP are variable

70
Q

1.2.7a
Define Price Mechanism

A

Adam Smith : ‘invisible hand of price mechanism’

Little govt intervention will benefit economy

C/P decisions interact to determine scarce resource allocations between competing uses

Ensures equilibrium met in free market

71
Q

1.2.7a
Rationing Function

A

Extension/contraction in D (brought about by supply shift)

Price rations scarce resources when D>S ∴only those willing/able to pay can purchase G/S
E.g ⬇️S = ⬆️D

Rationing function clears market of consumers not will/able to pay
E.G Auctions where price⬆️ till one buyer left them D=S

72
Q

1.2.7a
Incentive Function

A

Incentive motivates C/P to 🔺behaviour
Extension/contraction in S (brought about by D shift)

C choices send info to P about dynamic wants/needs

⬆️D = ⬆️Prices = incentive to ⬆️output (extension) as ⬆️profit for supplier
⬇️D e/g recession = supply contracts as producers ⬇️output

73
Q

1.2.7a
Signalling Function

A

Shift in D/S

⬆️prices = signal to C to ⬇️D or withdraw market + potential P enter market
⬇️prices = C enter market + P leave market

74
Q

1.2.7b
Price Mechanism in Local Markets

A
  • smaller scale
  • more sensitive to price changes due to limited options
  • local tastes, preferences, and income levels can significantly influence prices
75
Q

1.2.7b
Price Mechanism in National Markets

A
  • larger scale
  • more intensive price competition due to more competitors
  • National economic conditions, government policies, and consumer trends can influence prices
76
Q

1.2.7b
Price Mechanism in Global Markets

A
  • international market
  • trade barriers + exchange rate affect prices
77
Q

1.2.8a
Consumer Surplus

A
  • difference between price willing and actual
    Willingness = demand
    Actual = market
78
Q

1.2.8a
Producer Surplus

A
  • difference between minimum price producers willing to accept and able to accept
    Willingness = supply

81
Q

1.2.8c
Changes in S and D affecting surplus

A
  • increase D = both increase
  • decrease D = both decrease
  • increase S = increase in C + decrease in P
  • decrease in S = increase in P + Decrease in C

Typed of Indirect Tax

A
  • Ad Valorem
  • Specific
85
Q

1.2.9a
Ad Valorem Tax

A

86
Q

1.2.9a
Specific Tax

A

tax placed on each good is same regardless of price

87
Q

1.2.9a
Impact of Indirect Tax on C,P and govt

A
  • increases prices of G for C
  • reduce profits for P as higher cost of production
  • generate revenue for govt
88
Q

1.2.9a
Incidences of indirect taxes

A
  • consumer incidence on top
  • producer incidence bottom
89

Small producer incidence

90
Q

1.2.9a
Elastic demand curve on taxation

A

Small consumer incidence
Large producer incidence

91
Q

1.2.9a
Evaluating Tax

A
  • regressive tax : income not take into account thus poor ppl spend larger proportion of it on tax = increasing inequality. Problem exasperated if PED=in elastic + consumer tax incidence greater
  • unintended consequences : tax meant to reduce consumption but often will lead to switch to harmful substitutes thus solution = substitute taxed too
  • PED inelastic : large price increase = small demand increase (diagram) thus only effective is large enough
  • Laffer curve : if tax = too high > revenue will fall as other options seemed out e.g smuggling = other problems

  • importance of habitual behaviour
  • consumer weakness at computation
98
Q

1.2.10a
Consumers ≠ rational
Influence of other’s behaviour

A
  • individuals don’t make independent choices

  • herding behaviour = beliefs on how to behave
99
Q

1.2.10a
Consumers ≠ rational
Habitual behaviour

A
  • short cuts in decision making
  • e.g rule of thumb = quick but not accurate
  • Heuristic behaviour = mental short cuts
  • C don’t gather all info necessary for good decision as not time/effort worthy
  • e.g supermarkets put ⬆️profit G at eye level as ppl more likely to to buy these
100
Q

1.2.10a
Consumers ≠ rational
Weakness at computation

A
  • C cannot do maths to compare prices ∴firms exploit this but giving info disjointed or not enough
  • bounded rationally = C who make decisions based on analysing all info they have

119
Q

1.3.2e

A

We never know what Q* is exactly thus hard got govt to intervene as don’t know how much they need to intervene > info gaps

120

129
Q

1.4.1a
Purpose of Govt intervention

A

address market failure

130
Q

1.4.1a
State Government Interventions

A

1) Indirect Taxation
2) Subsidies
3) Max/Min prices
4) Trade Pollution Permits
5) State Provision of Public Goods
6) Provision of Information
7) Regulation

131
Q

1.4.1a
Government Intervention : Indirect Taxation + Subsidies

A

+deal directly w/ externality
+adjustable according to problem size
+shift MPC left
-difficult identifying Q* and external cost
-indirect taxes = regressive as ⬆️poor ppl income goes to tax= market failure
-PEDe.g if inelastic then ⬆️tax but still ⬆️D change

132
Q

1.4.1a
Government Intervention : Subsidies

A
133
Q

1.4.1a
Government Intervention : Min prices

A

When equilibrium = too low
Govt intervene to set artificial min price that sellers can sell
Aka price floor

This is done to protect firms in key industries e.g agriculture that are volatile to price changes (primary sector)
E.g industries w/ ⬆️employment have min as to avoid bankruptcy and ∴⬆️unemployment
E.g imported goods as to avoid firms exiting market as costs>profit

134
Q

1.4.1a
Government Intervention : Min prices EV

A

When price cannot revert to natural equilibrium then S>D ∴ surplus = problem and govt have to purchase these surplus to above firm ceasing production and ⬆️price= ⬇️demand
This created firm dependency on govt ∴ continue producing surplus ∴allocatively inefficient

Rationing/incentive function cannot operate and ⬇️price = extension demand + supply contraction

135
Q

1.4.1a
Government Intervention : Max prices

A

Price ceiling = market price too⬆️ this govt ⬇️

Reason = ⬆️prices ration goods so that D=S ∴ some C excluded form market as cannot afford goods e.g medicine

136
Q

1.4.1a
Government Intervention : Max prices EV

A

Rationing + incentive function cannot operate

Ceiling = ⬆️attractive to consumers then producers ∴ shortage
As
⬇️prices = ⬇️profit ∴ no incentive to produce goods
BUT
⬆️D (rationing function)
= serious problem as max prices usually for necessities

137
Q

1.4.1b
Government Intervention : Trade Pollution Permits

A

+give firms incentive to ⬇️pollution
+permits can be sold
+encourage firms to lower pollution below permit
-relies of the fact that external cost can be measures
-high admin costs w/ constant monitoring
-high polluting countries can buy permits from low polluting countries thus don’t need to reduce pollution
-developing countries excluded from permits but given credits for ‘certified reductions’

138
Q

1.4.1b
Government Intervention : Trade Pollution Permits App

A

1 permit = 1 tonne CO2
N.o of permits in circulation ⬇️ over time

If country ⬆️ more CO2 then allowed they:
1) purchase ⬆️ permits
2)invest in ⬇️ CO2
3) invest in developing country = ⬆️ carbon units for them

But they all ⬆️ costs of production thus MPC MOVE LEFT

139
Q

1.4.1b
Government Intervention : Trade Pollution Permits EV

A
  • n.o of permits not always set correctly due to info gaps of UN/EU thus ⬆️permits = cheap to buy/sell so no firm incentive
  • stockpiling during recession as ⬇️CO2 = permits used in future e.g Covid 2019
  • China + USA = top 2 contributors 27/11% respectively aren’t involved
  • unless strict regulations , firms can pollute as much as they want as cheaper to bride rather than decrease CO2
  • Q* = hard to set and might be hard to meet
  • no funds go from polluting firms to members of society dealing with problems caused by
140
Q

1.4.1b
Government Intervention : State Provision of Public Goods

A

Govt produced G/S mainly necessity
+govt has full control over quantity + price
+directly provide market w/ Q*
+bring consumers into market who typically can’t afford
-expensive
-info gaps so price+quantity hard to set
-govt knows to be inefficient e.g prices>if private sector did it
-privatisation
- reduced competition but ⬇️quantity + ⬆️prices
-leads to command economy EV
-EV lag time

141
Q

1.4.1b
Government Intervention : Provision of Information

A

Pass law that suppliers cannot exclude info gaps or place warning on G/S
+suppports firms/conusmers in rational decision making
+⬆️D = ⬆️MSB = closer to Q*
-can be ignored e.g ads
-⬆️costs for businesses
-⬆️govt expenditure to enforce these

142
Q

1.4.1b
Government Intervention : Regulation

A

laws set to reduce negative externalities e.g outdoor smoking
can place restriction or completely prohibit
+ individual circumstances can be analysed thus appropriate action can be taken
+easily understood but firms
-inspectors need to be employed at a cost
-investigations = expensive
-external cost needs to be measurable + quantifiable
-fine>cost so firm have incentive to stop

143
Q

1.4.2a
Cause of Government Failure

A

government intervention in the economy leads to a net welfare loss

144
Q

1.4.2b
Cause of Govt Failure

A
  • Distortion of Price Signals
  • Unintended Consequences
  • Excessive Administrative costs
  • Information Gaps
145
Q

1.4.2b
Cause of Govt Failure - Distortion of Price Signals

A
  • intervention will disrupt price mechanism
  • market failure = more serious market failure e.g subsidies = cheap prices = cheaper exports = foreign markets not competitive
  • minimum wage = unemployment
  • planning permission/ green belts decreases elasticity of housing market thus demand outstrips supply
  • more subsidies= less incentive to be efficient
  • EV subsidies give unfair advantage to developed counties + info gaps mean that subsidy level = difficult to set
146
Q

1.4.2b
Cause of Govt Failure - Unintended Consequences

A
  • ⬆️direct tax e.g more income tax discourages ppl from working = welfare trap as they are better off on benefits form govt
  • indirect tax redistributes income thus despite income everyone pays same e.g VAT+laffer curve +regressive as easier to live of benefits
147
Q

1.4.2b
Cause of Govt Failure - Excessive Administrative costs

A

Admin costs > welfare benefit

148
Q

1.4.2b
Cause of Govt Failure - Information Gaps

A
  • Hayek’s argument on why govt should not intervene
  • gathering all info = time consuming + expensive + opportunity cost
  • govt might get its calculations wrong
