1、Merit and Public goodsPrivate GoodsFirstly, what is and is not a public good? A private good or service has three main characteristics:1. Excludability: Consumers of private goods can be excluded from consuming the product by the seller if they are not willing or able to pay for it. For example a ti
2、cket to the theatre or a meal in a restaurant is clearly a private good. Another example is the increasing use of “pay-per-view” as a means of extracting payment from people wanting to watch exclusive coverage of sporting events on television or the payment required to travel on a toll-road or toll-
3、bridge. Another example of a private good is the use of subscription-based services on the internet. Some newspapers provide the bulk of their news stories on the internet as a “quasi public good” such as The Guardian www.guardian.co.uk. Others are developing an alternative business model where user
4、s can only access premium services through password-protected parts of a web site that require payment from consumers examples include The Economist and the Financial Times . Excludability gives the service provider (the seller) the chance to make a profit from producing and selling the product. As
5、we shall see, with public goods, such excludability does not exist. When goods are excludable, the owners can exercise property rights. 2. Rivalry: With a private good, one persons consumption of a product reduces the amount left for others to consume and benefit from - because scarce resources are
6、used up in producing and supplying the good or service. If you order and then enjoy a pizza from Pizza Hut, that pizza is no longer available to someone else. Likewise driving your car on a road uses up road space that is no longer available at that time to another motorist. The greater the volume o
7、f traffic on the roads, the higher the likelihood of traffic congestion which has the effect of reducing the average speed and increasing the average journey time for each road user. 3. Rejectability: Private goods and services can be rejected - if you dont like the soup on the school menu, you can
8、use your money to buy something else! You can choose not to travel on the railways instead, go by coach, or you can choose not to buy a season ticket for your local football club and instead use the money to finance a subscription to a local health club. All private goods and services can be rejecte
9、d by the final consumer should their tastes and preferences change. Private and Public Goods a question of exclusion Le Shuttle is a private good the service is excludable, rival in consumption and rejectable. But not all providers of public goods make a profit. EuroTunnel is facing large losses and
10、 even bigger debts!Characteristics of Public Goods As one might expect, the characteristics of pure public goods are the opposite of private goods: Non-excludability: The benefits derived from the provision of pure public goods cannot be confined to only those who have actually paid for it. In this
11、sense, non-payers can enjoy the benefits of consumption at no financial cost to themselves this is known as the “free-rider” problem and it means that people have a temptation to consume without paying! Non-rival consumption: Consumption of a public good by one person does not reduce the availabilit
12、y of a good to everyone else therefore we all consume the same amount of public goods even though our tastes and preferences for these goods (and therefore our valuation of the benefit we derive from them) might differ Examples of Public GoodsThere are relatively few examples of pure public goods. E
13、xamples of public goods include flood control systems, some of the broadcasting services provided by the BBC, public water supplies, street lighting for roads and motorways, lighthouse protection for ships and also national defence services. Policing a public good?To what extent is our current syste
14、m of policing an example of a public good? Some (but not all) aspects of policing might qualify as public goods. The general protection that the police services provide in deterring crime and investigating criminal acts serves as a public good. But resources used up in providing specific police serv
15、ices mean that fewer resources are available elsewhere. For example the use of police at sporting events or demonstrations and protests means that police resources have to be diverted from other policing duties. The police services must make important decisions about how best to allocate their manpo
16、wer in order to provide the most effective policing service for the whole community.Private protection services (including private security guards, privately bought security systems and detectives) are private goods because the service is excludable, rejectable and rival in consumption and people an
17、d businesses are often prepared to pay a high price for exclusive services. A good recent example of this has been the use of private security firms in post-war Iraq where up to 15,000 workers are said to have been working for private businesses protecting installations, coalition buildings and conv
18、oy protection.Public goods and market failurePure public goods are not normally provided at all by the private sector because they would be unable to supply them for a profit. Thus the free market may fail totally to provide important pure public goods and under-provide quasi public goods (see below
19、). It is therefore up to the Government to decide what output of public goods is appropriate for society. To do this, it must estimate the social benefit from the consumption of public goods. Putting a monetary value on the benefit derived from street lighting and defence systems is problematic. The
20、 electoral system provides an opportunity to see the public choices of voters but elections are rarely won and lost purely on the grounds of government spending plans and the turnout at elections continues to fall.The air waves a public good or a quasi public good?The airwaves used by mobile phone c
21、ompanies, radio stations and television companies are essentially owned by the government of a particular country. Do they count as a pure public good? Normally the answer would be yes. One persons use of the airwaves rarely reduces the extent to which other people can benefit from utilising them. B
22、ut when demand for mobile phone services is high at peak times, the airwaves become crowded and as a result access to the networks can become slow. In this sense the airwaves can be treated a crowded non-pure public good. The government also controls the issue of licences needed to operate mobile ph
23、one services using the airwaves in the UK. In 2000, they auctioned off five licences for 3rd generation mobile phone services and raised 22 billion in doing so. Quasi-Public GoodsMost public goods are non-pure public goods these are also known as quasi-public goods. The main reason is that we can fi
24、nd ways and means of excluding some groups from consuming them!A quasi-public good is a near-public good i.e. it has many but not all the characteristics of a public good. Quasi public goods are: Semi-non-rival: up to a point, extra consumers using a park, beach or road do not reduce the amount of t
25、he product available to other consumers. Eventually additional consumers reduce the benefits to other users. Beaches become crowded as do parks and other leisure facilities. Semi-non-excludable: it is possible but often difficult or expensive to exclude non-paying consumers. E.g. fencing a park or b
26、each and charging an entrance fee; building toll booths to charge for road usage on congested routes The diagram below is one way of illustrating the different characteristics of public and private goods.The BBC as a public good Broadcasting is a good example of a public good. Let us remind ourselve
27、s of the three main characteristics of a public good. Firstly it is non-rival, meaning that the consumption of a public good or service by one individual does not preclude consumption by another individual. Secondly, consumption is non-excludable. This means that consumption by one individual makes
28、it impossible to exclude any other individual from having the opportunity to consume. Effectively the cost of providing a pure public good to an extra user is zero, and this implies that, in order to achieve allocative efficiency, the charge for the product should be zero. Of course, in this situati
29、on, private sector businesses are unlikely to consider providing pure public goods because they will not be able to make any profit at a zero price, and many consumers can take a free ride on such goods because of non-excludability. The provision of pure public goods is therefore a cause of market f
30、ailure. Left to the free market, public goods are under-provided and under-consumed leading to a loss of social welfare.At the moment, around 23 million households in Britain pay an annual licence fee. All of these people are stakeholders in the debate about the future funding of the BBC and the vas
31、t majority use one or more BBC services at least once a week. The fee is a means of providing collective payment for a public good. We know that there are fee-dodgers who try to take a free-ride by avoiding payment, but there are well established although costly means to enforce the licence fee and
32、take non-payers to court.Of course the BBC is now facing huge competition from broadcasters such as Sky who are able to exclude people from their services through the use of subscription-based services. Skys financial muscle continues to grow. The case for government intervention in the case of publ
33、ic goods The non-rival nature of consumption provides a strong case for the government rather than the market to provide and pay for public goods. Many public goods are provided more or less free at the point of use and then paid for out of general taxation or another general form of charge such as
34、a licence fee. State provision may help to prevent the under-provision and under-consumption of public goods so that social welfare is improved. Public bads A public bad is the opposite of a public good it provides disutility or dis-satisfaction to people when consumed and therefore reduces our econ
35、omic welfare. A good example to look at would be the disposal of household and commercial waste.People are normally prepared to pay a price for their household waste to be collected and disposed of in a safe and non-polluting way. But if waste was changed for according to how much had been generated
36、, then some people would find an incentive to dump their waste on other peoples property and thereby avoid direct charges.The economics of waste is it a public bad? Waste is now a major economic problem. As a nation, the UK generates over 430 million tonnes of waste each year, the majority coming fr
37、om municipal, industrial and commercial sources. Each household is estimated to produce over 500 kg of waste per person each year and we throw away nearly a tonne of waste each over the course of twelve months! Waste is a nuisance good that has a negative effect on our welfare. From unsightly waste
38、products to the costs of clearing up and disposing of waste, there are many private and external costs arising from the mountain of detritus that comes from our homes every day.But how much are we prepared to pay for waste collection and disposal? The current situation is that local authorities have
39、 a legal responsibility to collect household waste once per week, the private sector “market” does not provide the bulk of waste collection services for households although they have a role to play in providing waste services for businesses and other larger organisations. Household waste collection
40、is nearly always done “free at the point of collection”. This raises questions of equity and efficiency and also the issue of whether there are better ways of providing incentives for us to create less waste as our living standards improve. Why should a large family that fills many wheelie bins ever
41、y week pay the same as a single householder who creates just one or two bags worth of rubbish?Can economists come up with good ideas to reduce waste and to give people the right incentives to dispose of their waste in an environmentally friendly way?Merit goodsMerit goods are goods which the governm
42、ent feels should consume, but tend to under consume and which therefore ought to be subsidized or provided free at the point of service.Who provides merit goods? It is important to realise that it is not simply the government (or public sector) that supplies merit goods. Both the state and private s
43、ector provide merit goods & services. We have an independent education system and people can buy private health care insurance. Externality issues: Consumption of merit goods is believed to generate positive externalities- where the social benefit from consumption exceeds the private benefit. Merit
44、goods museums and librariesWhat are the external benefits that might flow from more people having access to our major museums and other heritage sites?Merit goods can be defined in terms of their externality effects and also in terms of informational problems facing the consumerA merit good is a pro
45、duct that society values and judges that everyone should have regardless of whether an individual wants them. In this sense, the government (or state) is acting paternally in providing merit goods and services. They believe that individuals may not act in their own best interest in part because of i
46、mperfect information about the benefits that can be derived. Good examples of merit goods include health services, education, work training programmes, public libraries, Citizens Advice Bureaux and inoculations for children and students. Notice here that we are talking about the sorts of goods and s
47、ervices that society judges to be in our best welfare. Judgements involve subjective opinions and we cannot escape from making some valued judgements when we are analysing and discussing merit goods. Do you believe that most National Health Services and dental services should be made available free
48、at the point of need? Should the state continue to provide free and compulsory education up to the age of 16? Should people be forced to make compulsory savings for their retirement?

Parents with relatively poor educational qualifications may be unaware of the full longer-term benefits that their children might derive from a proper education. Because the knowledge of these priva
