Subsidies and indirect taxes done
Market failure = When the price mechanism leads to an inefficient allocation of goods and services and a dead weight loss of economic welfare
Examples of market failure:
Neg and Pos externalities - self interest as firms are profit maximisers and consumers are utility miximisers
Under provision of public goods - free rider
De-merit goods/ merit goods - information failure which may make consumers make irrational decisions when purchasing
Information failure
Monopolies - one dominant seller and high barriers to entry
Inability of the factors to move
Effectiveness:
Depends on the PED
Problems associated with setting tax at the right level yo achieve aims
Unintended consequences - i.e. inequality
Does it raise revenue ? Does it generate sufficient revenue especially in elastic demand
How is the tax revenue used ? Is it used for a specific purpose i.e. sugar and sport in primary schools.
What are the effects on competitiveness ? Will businesses cut back on jobs or investment ?
Consequences for equity/ redistribution on wealth ? Who are the winners/ losers ? Is it regressive i.e. VAT
Effectiveness:
Will they achieve their desired stimulus / incentivise an increase in demand i.e. if PED is low there may need another incentive
Will a subsidy effect productivity and efficiency ? Subsidies for research and investment will bring about positive spillovers but cane some firms become too dependant on govt. subsidies
How much does the subsidy cost ? Who is pay? Is it part self financing i.e. creates more jobs therefore generates more taxation or will it create an added burden onto the tax payer.
Does it really correct market failure ???
Minimum price + = a legally imposed price floor mostly associated with minimum wages
Or Minimum price per unit i.e. Scotland and alcohol at 50p per unit and minimum care price
Always consider PED for labour ect. to build analysis - when considering the extent of contraction of demand
Aim: not to contract supply rather decrease/shift demand
Disadvantages:
If demand has a high PED ( elastic ) this could hit production, profits and jobs in the drinks industry
Impact on high consumption groups may be regressive in nature
Doesn’t actually bring in any tax revenue for the govt. for reinvestment
Causes excess supply in the market - market distortions - over production
These surpluses may require extra govt. intervention such as storage and export subsidies to prevent waste
Risks of waste dumping and trade wars - which may occur if nations are accused of waste dumping to get rid of extra stirage
Minimum price may discourage innovation and efficiency esp in agri market
What are the alternatives:
Indirect taxes
Behavioural nudges i.e. provision of education to change demand - lessen imperfect info
Raise minimum drinking age to 21 - regulation
Minimum Prices for Farmers:
So, this is usually a positive as farmers are essentially price takers
So minimum prices in the agri industry is designed to stabalise farmers incomes and ensure they receive at least a certain amount for their produce i.e. corn and wheat
By setting a floor price the govt. ensures farmers are receiving a minimum level of income to cover all costs of production to maintain livelihood and protect smaller farmers
Maximum prices act as a price ceiling of which suppliers cannot exceed i.e. Rent control in Oregon and energy price caps
I.e. Paydays loans at 0.8% and gambling
Evaluating ( i.e. Rent )
Lead to an extension in Demand from Q1 - Q3 as consumer surplus increases and more people can now afford
However, in turn this results in a shortage of supply due to the now excess demand in a market - distorting the price mechanisms
If some people are willing to pay higher prices this risks black market transactions which results in an even higher price
Benefits
Rent controls are needed to reduce excess profits of landlords from those in need
High rents impede on the geographical mobility of labour which may in turn have a direct affect on unemployment
High rents reduce peoples disposable income which will cause a decrease in AD as well as an increased reliance on the benefits system - taxes
Drawbacks:
May result in landlords withdrawing from investment resulting in a diminished supply of private sector rented housing
Landlords may cut back on large levels of maintenance spending reducing the quality of rented housing and increase risks for tenants - external costs - i.e. dampness
Some landlords may switch markets from rented property to houses to buy which will ultimately increase housing prices
In evaluation in the exam always consider alternatives for example:
Govt could consider tax relief when building affordable houses on brownfield sites
Increased spending on social housing
Always discuss PED
May benefit from better education - to reduce imperfect knowledge
Contextual knowledge: Rent in London is over double that of Newcastle - also 3x
Means to target climate change
Used by the UK and India - fairly common
Aim to reduce CO2 emissions
Cap set at socially optimum level assuming that govt. know what this is
Permits are issued to match the cap exactly
A markets for permits is then created - a market for sollution
Supply is then vertical because supply of permits is inelastic
Firms then have to make a decision as to whether it would be more cost efficient to operate in an environmentally friendly way i.e. invest in green tech or buy permits - whereas blanket regulation does not give firms this choice
Then pollution will be reduced to the socially optimum level of output and allocative efficiency will be achieved as a result
AND in turn the LR incentive is to invest in green tech so they won’t be burdened when permit prices rise and as the govt. gradually tighten the cap - this is socially beneficial
Evaluation:
Can enforcement be afforded ? Especially in developing countries - without enforcement and technology ti measure emissions then policy won’t work
Imperfect information - govt. do not know the socially optimum level
Unintended consequences - due to imperfect info, govt. could set the cap too high and then LRAC will increase for a firm - resulting in higher prices ( inflationary )or simply shut down or move to different countries where policies are more lacked - results in carbon leakages
There needs to be international cooperation for this policy to work - climate change is a global issue - but getting international countries is near impossible especially in LDC who are industrialising - annoys developed economies
Direct provision of goods and services at the point of consumption provided by the govt.
Benefits:
Left to the free market there is inequity of merit goods
This is because prices are charged
I.e. education and healthcare
Therefore, it could be argued that state provision in these industries is justified
AND public goods - free rider problem
Assumed that govt. has near perfect information about MSB and MSC and all externalities are valued and the govt. is aware of the socially optimum level of output
Vertical supply curve because the govt. designate a proportion of spending per year to the NHS and education
NO price as free at the point of consumption
This can then used to be solve under consumption and under production issues compounded with inequity issues also - caused by the free market
Then, allocative efficiency is achieved as is the maximum welfare
BUT this is all in theory, in reality there is far more issues created by state provision than solved
Evaluation:
Excess demand - distorts price mechanism - QD exceeds Q* - left to the free market, rationing would boost prices - govt. can’t do this - causing large back logs and queues - lots of people living in pain - not an efficient solution - i.e. postcode lottery regarding provision of education
Cost - consumers don’t pay in price but they may pay in other ways such as pain or poor quality - therefore, an argument for the needs for a private sector here - consumers that are willing and able to pay will do - this reduces state pressure
Opportunity cost - tax payers money - LR funding - higher taxes - redirected spending
Imperfect info - govt. don’t know everything i.e. value of externalities - so may result in further distortions
Inefficiency - as argued by free market economists - public sector lacks a profit incentive - therefore lacks sufficient efficiencies - may suffer from x-ineffiiciency and then taxes suffer - effective use of public money ?
