2.7 role of government (government intervention) Flashcards
purpose of indirect tax
- increasing tax revenue
- correcting market failure (negative externalities, demerit goods)
main forms of government intervention in markets [6]
1) Indirect taxes
2) Subsidies
3) Price control: price ceilings & price floors
4) Command and control regulation and legislation
5) Direct provision of goods and services
6) Nudges (HL only)
examples of the purposes of indirect tax
- increasing tax revenue
- e.g. onsen hot spring in Japan
- correcting market failure (negative externalities, demerit goods)
- e.g. discourage people from using indoor tanning services in US, risks of skin cancer from UV light exposure
- e.g. tax on junk food in Hungary
e.g. Bachelor tax in South Africa
indirect tax
tax imposed on spending (goods & services)
direct tax
tax imposed on income, profits and wealth
excise tax
an indirect tax on a specific good or service
specific tax
a fixed amount of tax per unit of good or service sold
Why does a supply curve shift upwards when as indirect tax is applied?
Indirect taxes are paid by the firm to the government
- Therefore, for every level of output the firm is willing to supply to the market, it must receive a price that is higher than the original price by the amount of tax
Ad Valorem tax
tax calculated as a fixed percentage of the price off the good or service
examples of excise tax in HK
- alcohol, petrol, cigarettes, for new cars only in general
- demerit goods, want to discourage consumption
why impose taxes?
1) Government revenue
2) Distribution of income
3) Correcting negative externalities to improve allocative efficiencies
- e.g. influencing level of production
- e.g. influencing level of consumption
is tax revenue a loss to society?
tax revenue is not a loss to society b/c tax revenue is reinvested into the economy in the form of welfare, education etc.
effect if indirect tax on stakeholders
- Consumers :(
- CS decrease → price increase & quantity decrease
- Producers :(
- PS decrease → price decrease & quantity decrease
- Workers :(
- Total revenue decrease ⇒ P1Q1 → P3Q2 → lower production → fire workers (lower COP)
- Government :)
- Tax revenue
- Society :(
- Deadweight loss, SS decrease due to dwl
what happens to the allocation of resources when an indirect tax is imposed
underallocation of resources
- the society is allocatively efficient when production is at Q0
- society is being worse off as less goods are produced at Q1
what is the assumption made about a good before government intervention
good before government intervention – is at allocative efficiency
Why is there a deadweight loss when the supply curve shifts to the left?
- Assumption → before government intervention, everything allocated most efficiently
- Q0 → allocative efficiency
- To measure allocative efficiency: look at the quantity
- In society: prefer Q0, but now only Q1 → underallocation of resources → misallocation of resources
subsidy
financial support to individuals or groups for reducing costs of production
purpose of subsidies [5]
- Increase producer revenue (e.g. agricultural products)
- Make necessities more affordable
- Encourage production and consumption of socially desirable/merit goods or services (correcting allocative efficiency) (e.g. vaccinations and education)
- Support the growth of particular industries (e.g. enterprise support scheme for R&D in HK)
- Encourage exports
consequence of subsidies to different stakeholders
Consumers :)
- Price decrease :), Quantity increase :) → CS increase
- CS area: abcgf (old CS: ab) (gain = cgf)
Producers :)
- Price increase :) (price they receive increases, P2+unit subsidy=P3), Quantity increase :) → PS increase
- PS area: bcdh = [hij+? (paralellogram)] (old: ch) (gain bd)
Foreign producers :(
- their prices may be higher than local prices → discouraging people from buying from foreign producers (price includes import fees as well)
- Not as competitive (as locally produced goods)
Workers :)
- Producer’s TR increase (b/c P3Q2 > P1Q1)
Government :(
- Sub expense (increased government expenditure)
- area: efgbdc (loss = bcdefg)
Society :(
- deadweight loss
- producers may become over reliant on subsidy → complacency
- not good for society → not at allocative efficiency
how to find dwl?
- gains from surpluses vs losses from surpluses
- gain does not exceed the cost by the government (subsidy)
what happens to the allocation of resources of the good when a subsidy is imposed?
there is an overallocation of resources
- The society is allocative
- The society is allocative efficient when production is at Q1
- Society is being worse off as too many goods are produced at Q2
price controls
government setting maximum (price ceiling) OR minimum (price floor) price on goods and services
price ceiling
below equilibrium price, bc equilibrium price too high
price floor: when P is too low
price floor
above equilibrium price, so producers can receive higher price (e.g. wage)
reduce people’s consumptions → Qd decrease → fix market failure
- price ceiling: when P is too high
