They are a market failure, which means the government needs to intervene in the market to ensure they are provided. Because they bring significant social benefits we also consider them to be merit goods.</p><h4><strong>Public goods have two characteristics:</strong></h4><h5><strong>Non-rivalrous </strong></h5><p>Non-rivalrous means the consumption by one individual does not reduce the availability to others. For example, if a group of people are benefiting from a public good like street lighting and an extra person comes along to take advantage of the light the availability to the existing consumers is not reduced. This means the marginal cost (the cost of providing the good to an additional consumer) of providing a public good is zero once it is set up and being produced. The extra person who benefits from street-lighting adds nothing to the cost of providing the streetlight.</p><p><strong>Non-excludable </strong></p><p>Once a public good is being produced it is impossible to stop people from benefiting from it. Once streetlights are turned on it is impossible to stop people from benefiting from them, assuming they can get to an area covered by the lights.</p><p><strong>Examples of pure public goods</strong></p><div class="polaroid-left"><img height="304" src="../../../ib/economics/images/textbook/market-failure/flood-barrier(1).jpg" style="margin: 8px 0px;" width="283"><div class="caption">The Thames flood barrier in London</div></div><p>There are not many examples of pure public goods, but economic theory would normally include flood barriers, sea defences, street lighting and national defence.</p><p>Economists often distinguish between pure public goods and quasi-public goods. Quasi-public goods have some elements of being non-rivalrous and non-excludable but not in the precise way that defines pure public goods. Examples include roads, bridges and public parks. Roads have some of the characteristics of public goods, but the space on a road can be looked at as being rivalrous when too many cars use them, and they can be excludable if tolls are in place.</p><hr class="hidden"><h3><strong>Public goods as a market failure</strong></h3><p>Public goods are considered an example of market failure in pure free markets because they would not be produced. This is because of the ‘free rider’ problem. Once a public good is set up and being produced it is impossible to prevent people from benefiting from it (non-excludability) even if they have not paid for the good: some individuals free ride 'on the back' of the consumption paid for by others. </p><p>Consider the example of a town that keeps being flooded by a river. The town needs a flood defence. A group of people who live alongside the river think of pooling their money to pay for flood defences, but they do not have enough money to pay for the barrier unless the whole town contributes.</p><hr class="hidden"><hr class="hidden"><p><img alt="" height="312" src="../../../ib/economics/images/textbook/market-failure/public-goodc.jpg" style="float: right;" width="422">Large numbers of people in the town choose not to contribute as they know that once the flood barrier is built they can benefit from it without paying – they can <strong>free ride</strong> on the consumption of those who do pay. This means the market price of the flood barrier will not be high enough for it to be provided. Public goods like flood barriers often have very high initial set-up costs so even wealthy philanthropic individuals would not be able to fund their provision.</p><hr class="hidden"><p>Diagram 2.53 shows how the socially efficient output of the blood barrier at Q* where MSB equals MSC. The MSC curve in this case is horizontal at C because the marginal cost of an additional user of a flood barrier is zero. Once the flood barrier is set up the marginal cost of providing it to each additional consumer does not change as more consumers benefit from it. If the flood barrier costs $1Bn the cost will not change if two million people benefit from it or three million people benefit from it. Remember, this is hypothetical because in a free market the flood barrier would not be built. Because the output is zero in the market the whole yellow shaded area is the welfare loss.</p></div><div class="pinkBg"><div class="panel panel-has-footer" style="box-shadow: rgba(17, 34, 51, 0.3) 0px 10px 30px -15px; border-color: rgb(39, 45, 105);"><div class="panel-heading" style="background-color: rgb(39, 45, 105);"><a class="expander pull-right" href="#"><span class="fa fa-plus"></span></a><div><h4><strong>Inquiry case example - The 250mile sea wall</strong></h4></div></div></div><p>J<strong><img alt="" src="../../../ib/economics/images/textbook/market-failure/japan-sea-wall(1).jpg" style="float: left; width: 337px; height: 422px;" title="https://www.reuters.com/article/us-japan-disaster-seawalls/seven-years-after-tsunami-japanese-live-uneasily-with-seawalls-idUSKCN1GL0DK"></strong>apan suffered an earthquake off its coast in 2011 that triggered a devastating tsunami. Whole swathes of land near the coast were flooded with seawater in just 6 minutes. Nearly 18,000 people died, and the Japanese economy was severely affected.</p><p>To try and deal with a future Tsunami the Japanese government built a 250 miles coastal wall which is 12.5 metres high at a cost of $13 billion. The wall has come with external costs though. It is having a negative impact on tourism because there is no longer a view of the sea from the towns dotted along the coastline. Indeed the residents of these towns find the view of a wall rather than the sea as almost ‘prison-like’.</p><hr class="hidden"><h5><a href="../../../media/ib/economics/images/textbook/market-failure/public-goods/japanese-sea-wall.pdf.html" target="_blank" title="Questions"><img class="ico" src="../../../thinkib/icons/question.png"> Worksheet questions</a></h5><h5>Questions</h5><p><strong>a.

Where a public good is something society should provide (street-lighting, defence and flood defences) the government can intervene through direct state provision. Quasi-public goods like parks, the police and street cleaning will be under-provided in a free market and governments intervene to produce quasi-public goods at the socially efficient level of output.</p><h4><strong>State provision</strong></h4><p>Where governments see the provision of a public good as crucial to society they will set up and provide the public good. Most countries have public goods that are set up and provided by the state. Public goods such as national defence, flood defences and street lighting are directly provided by the government and funded through taxation.</p></div><div class="pinkBg"><div class="panel panel-has-footer" style="box-shadow: rgba(17, 34, 51, 0.3) 0px 10px 30px -15px; border-color: rgb(39, 45, 105);"><div class="panel-heading" style="background-color: rgb(39, 45, 105);"><a class="expander pull-right" href="#"><span class="fa fa-plus"></span></a><div><h4><strong>Inquiry case example - Defence spending in the USA</strong></h4></div></div></div><hr class="hidden"><p><strong><img alt="" height="159" src="../../../ib/economics/images/textbook/market-failure/defence-spending.jpg" style="float: right;" width="342"></strong></p><p>The current level of spending on annual defence by the US government is $934 billion. This is almost 4 per cent of its GDP. It spends 3 times as much as China which is the next biggest spender on defence. The decision by the US to spend as much money as it does on defence is heavily influenced by political factors. It does, however, come at a significant opportunity cost in terms of other items of expenditure the US government could spend its money on such as health and education.</p><hr class="hidden"><h5><a href="../../../media/ib/economics/images/textbook/market-failure/public-goods/defence-spending.pdf.html" target="_blank" title="Questions"><img class="ico" src="../../../thinkib/icons/question.png"> Worksheet questions </a></h5><h5><strong>Question</strong></h5><p><strong>Explain why national defence is an example of a public good.

[4]</strong></p><section class="tib-hiddenbox"><p>The free-rider problem occurs in the provision of public goods because once a public good is set up and being produced it is impossible to prevent people from benefiting from it (non-excludability).

Remember the free market will not generate a price that can support the production of a public good.</li><li>Governments are more likely to provide quasi-public goods near the socially efficient output.</li><li>When the government is providing a public good it is more likely to make decisions in the public interest compared to private sector businesses that aim to make a profit. This could be important in the provision of quasi-public goods such as parks.</li><li>Governments can provide public goods at zero price so they are available to low-income households.</li></ul><p><strong>Disadvantages of state provision:</strong></p><ul><li>The cost of providing state-funded and managed public goods are extremely high and there is a significant opportunity cost to the government in terms of other areas of expenditure.</li><li>Some people question the efficiency of state-run organisations that provide public goods.</li><li>State-managed and organised public goods can be influenced by political decision making which may not be in the best interests of society.

In the 1980s the private prison industry started to boom. Currently, about 20 per cent of prisoners are kept in private prisons and this multi-billion-dollar industry is growing. CoreCivic is the largest operator of private prisons in America with a revenue of $1.77 billion.</p><p>Prisons can be considered a public good because they are non-rivalrous and not excludable. People in society benefit from the protection they get from prisons when criminals are locked up. Most countries use a state-owned and managed system, but in the US there are private sector prisons as well.</p><p>The US government pays private prison operators $23,000 per year per inmate. In addition, the government pays for every space in a private prison, even if it is not full.</p><hr class="hidden"><p>Other private businesses have been involved in supporting private prisons: Bank of America, JP Morgan Chase and BNP and US Bancorp have all played a role in financing private prison companies because there is so much profit to be made.</p><p>It is a flourishing business but there are costs. Conditions in private prisons can be very poor and they are often not staffed at appropriate levels. The incidence of violence, consumption of recreational drugs and suicides are very often above those of prisons run by the government.</p><p><a href="../../../media/ib/economics/images/textbook/market-failure/public-goods/prisons.pdf.html" target="_blank" title="Questions"><img class="ico" src="../../../thinkib/icons/question.png"> Worksheet questions</a></p><h5>Questions</h5><p><strong>Using a real-world example, evaluate the effectiveness of state provision of public goods.

The diagram shows how the state provision of a public good means the yellow area of welfare is gained. <hr class="hidden"></li><li>An explanation that government have to intervene in the market for public goods because of the non-rivalrous and non-excludable nature of public goods which leads to the free-rider problem. This means a price will not be high enough for producers in the free market to provide a public good and the state needs to step in and produce the public good.<hr class="hidden"></li><li>An example of how a government directly provides a public good such as the sea wall in Japan.</li><li>Evaluation might cover the problems of state provision of public goods such as the opportunity cost of government expenditure in other areas and possible inefficient government management of public good provision. The answer could also consider an alternative to state provision such as state finance and private sector management in the prison sector in the US.</li></ul></section><h5>Investigation</h5><p><strong>Find out about some other public goods or quasi-public goods where there is private sector management of their provision. </strong></p></div><div class="panel" style="box-shadow: rgba(38, 0, 0, 0.3) 0px 10px 30px -15px; border-color: rgb(124, 7, 21);"><div class="panel-heading" style="background-color: rgb(124, 7, 21);"><a class="expander pull-right" href="#"><span class="fa fa-plus"></span></a><div><p>Thinking about a key concept - Intervention</p></div></div><div class="panel-body" style="background-color: inherit;"><div><p>Even to the most ardent believers in the free market, it is difficult to argue the case against state intervention in the market for public goods.
