micro 2.7- government intervention Flashcards
give 7 reasons for government intervention in markets
- earn govt revenue
- support firms
- support households on low incomes
- influence levels of production
- influence levels of consumption
- correct market failure
- promote equity
state 4 main forms of government intervention in markets
- price controls: price ceilings (max prices) and price floors (min prices)
- indirect taxes and subsidies
(- direct provision of services - command and control regulation/legislation)
define a specific tax
a tax imposed on an absolute value per unit of good sold (eg fuel tax, tobacco duty, alcohol duty, sugar tax, like £1 per unit)
define an ad valorem tax
a tax imposed on a fixed percentage of the price of the good (eg VAT)
describe how an ad valorem tax changes a supply/demand diagram
ad valorem tax will cause an increase in the cost of production so the supply curve will decrease and shift to the left
steeper gradient than original supply curve
describe how a specific tax changes a supply/demand diagram
specific tax will cause an increase in the cost of production so the supply curve will decrease and shift to the left
same gradient as original supply curve
distinguish between an indirect tax and a direct tax
direct - a tax paid directly to tax authorities (ie tax on income)
indirect- taxes on expenditure (consumer->producer->govt)
why does consumer and producer burden depend on the PED of a product?
if the product is elastic, producer burden will be higher- producers will keep tax burden themselves as they do not want to lose customers due to raised prices
evaluate the effect of taxes on stakeholders in the market
consumers:
- More expensive products and then enjoy less (Q2)
- CS decreases
- Consumer expenditures depend on PED. If PED is inelastic then expenditures increase and if PED is elastic then expenditures fall
- Lower income groups suffer more as VAT is a greater proportion of their income (regressive tax)
- If the tax is placed upon a harmful good then consumers might benefit if they consume less
producers
- TR drops
- producer surplus decreases
- international competitiveness may fall because they now seem more expensive, causing exports to decrease
governments:
- Their tax revenues increase
- If the tax revenues are used efficiently then the whole society will benefit
society:
- Under allocation of resources since quantity will decrease so unemployment in the specific sector might increase
- deadweight loss since resources as misallocated, unless the tax is used to lower production of harmful goods
why do govt prefer to tax goods with inelastic PED?
Their tax revenues are higher
Less damage to producers
Less increase in unemployment
The tax burden will be spread amongst many consumers instead of few producers
give 4 reasons why govt give subsidies?
- To make necessities more affordable for lower income households
- To provide more merit goods (benefit society), eg vaccines/education
- To make domestic producers more competitive and thus to be able to compete with foreign producers and increase exports
- To protect the environment by subsidising green technologies
define subsidies
payments made by the government to producers to increase production
state the effect of subsidies on a supply/demand diagram
decrease cost of production so supply curve increases and shifts to the right
when PED is inelastic, benefit to producers due to subsidies is ? than consumers. why?
smaller; consumers were going to buy it anyways but now they can spend less
evaluate the effect of subsidies on stakeholders in the market
consumers:
- Cheaper products and they can enjoy more
- consumer surplus increases
- consumer expenditures depend on PED
producers:
- TR increases
- producer surplus increases
- international competitiveness may increase (when prices are lower, exports may increase)
- greater risk of producers becoming inefficient
- foreign producers will seem less competitive (small scale farmers from LDCs won’t be able to compete with large scale subsidised farmers ->inequity)
define maximum prices
prices set by the government below the equilibrium price, which prevents producers from raising the price above it.
give 2 examples of countries with maximum prices
Example 1 - Venezuela (milk, toilet paper, medicine and rice)
Example 2 - Manhattan ( rent controls)
give 3 reasons why maximum prices exist
To protect low income consumers from high free market prices
To restrict monopolies from raising prices and exploiting consumers
To resist very high salaries (caps on pay and bonuses, CEOs and NBA)
evaluate the imposition of maximum prices
- There is a shortage as Qd>Qs
- There is underallocation of resources
Consumers:
- sometimes they are better off as they enjoy the product at a lower price
- some are worse off as they don’t get to enjoy the product due to the shortage
- it is important to protect low income families from high food prices as food is the largest proportion of their income and so if prices increase they may not be able to buy necessities
Governments: lower tax revenues due to less VAT
Producers: their total revenue falls
Price mechanism is distorted and the rationing method fails as a result.
The impact on the different stakeholders depends on how low the Pmax was set (and the PES and PED, more elastic means more impact)
give 2 negatives of price maximums
limited quantity may be rationed unfairly:
- connections/favouritism (discrimination e.g people with small children may not get a house)
- Black markets ( the more inelastic the PED the more likely it is to have black markets)
how does the govt resolve problems created by the shortage?
Increase supply by providing subsidies
Increase supply by providing products themselves
Direct provision from imports from abroad given out by the government
define rent controls
the maximum legal rents in order to make housing more affordable for low income group
how do maximum prices affect supply/demand graph?
line BELOW equilibrium
evaluate the imposition of rent controls
landlords:
- earn less.
- the ones that give their houses through black markets earn more
- When landlords switch to Airbnb in order to avoid rent controls, the supply of rented accommodation decreases (there is a max amount of days you can rent it)
tenants:
- some find cheaper accommodation
- some might find a lower quality house as landlords don’t have the incentive to maintain them
- some tenants are worse off as they don’t find any accommodation due to the shortage (Qd>Qs)
