Digital money, such as cryptocurrencies, is increasingly being used. Digital money transactions take place on electronic devices such as computers and smartphones. However, there can be market failure due to external costs arising from high energy usage of non‑renewable sources. One way of reducing external costs is to tax the product. 

• Analyse the consequences of market failure. [6] 

• Discuss whether or not a tax on a product can reduce external costs. [8]

Many people from the Philippines work in another country, often in industries that provide merit goods and public goods. In 2020, the Philippine government raised more tax revenue. Some was spent on policy measures to increase life expectancy and some on policy measures to reduce unemployment. The country’s unemployment rate was also affected by a rise in the country’s foreign exchange rate.

• Explain, with examples, the difference between a merit good and a public good. [4]

In 2020, the largest Thai commercial bank merged with a smaller commercial Thai bank. It was expected that the merger would affect the price charged for bank services and the amount that would be lent. Thai commercial banks operate in the private sector. A growing private sector can move an economy towards a market economic system.

• Discuss whether or not a market economy allocates resources in the best possible way. [8]

Living standards, including education, have improved for most people in South Africa in recent years. Most households have more money and the government has more tax revenue. There is, however, considerable income inequality. In 2020, 36% of the population were living in poverty. An increase in unemployment benefit payments might reduce this poverty.

• Explain how improved education may affect the demand for cigarettes and for fresh fruit. [4]

Vietnam has a high number  of female entrepreneurs. Some of their firms have grown and now compete with foreign multinational companies (MNC) and public sector firms. The Vietnamese government encourages MNCs to locate in Vietnam as a host country. It also intervenes in the economy to encourage the consumption of merit goods.

• Analyse how a government could encourage the consumption of merit goods. [6]

There is an area of rubbish, three times the size of France, floating in the Pacific Ocean called the Great Pacific Garbage Patch. It is made up of rubbish including old fishing nets but most is plastic waste. It is forecast that, by 2050, there will be more plastic in the Pacific Ocean than fish. A number of islands in the Pacific Ocean specialise in fishing. Greater pollution will increase the social cost of the fishing industry. 

• Identify the two types of costs that make up social cost. [2] 

• Analyse how cleaning up pollution could benefit an economy. [6]

Changes in tobacco production and consumption can have both microeconomic and macroeconomic effects. Tobacco plants are grown in at least 124 countries with different levels of development. A higher proportion of the poor than of the rich consume tobacco products. The market for cigarettes, produced using tobacco, is changing. Demand for cigarettes and some other demerit goods is declining in a number of countries. 

• Discuss whether or not government intervention will correct the market failure caused by a demerit good. [8]

The population of Hungary is the most obese in Europe. Hungarians eat fewer vegetables than most Europeans and more food types that may be considered to be demerit goods. In 2017, the Hungarian government introduced a tax on unhealthy food, known as the chips tax. The tax has had some success in moving demand to healthier foods. Some economists suggest that governments should use price controls as well as taxes to influence the food market. 

• Define demerit good. [2]

There is a high level of division of labour in the United Kingdom (UK) energy industry. Cold weather in early 2018 caused very high demand for energy and a change in its price. This led to a temporary shortage of energy for firms and households in the UK. Part of the change in price may have been the result of UK energy firms abusing their monopoly power. This would be an example of market failure. 

• Define market failure. [2]

The Indian government has declared that the country, now a major car producer, will sell only electric cars by 2030. The government wants to reduce external costs, some of which are caused by petrol and diesel cars. Demand for electric cars is currently relatively low and price-elastic. The government, however, thinks that it will not need to subsidise the production of electric cars to achieve its target. 

• Define external costs. [2]

Australian firms have been praised for introducing new technology. The actions of some of these firms, however, cause market failure. The Australian government uses subsidies, among other policies, to reduce market failure. Government spending is used both to improve the performance of individual markets and the macroeconomy. The Australian government increased its spending in 2017, in part to reduce unemployment. 

• Explain how a subsidy can correct market failure. [4]

Botswana has a number of conservation projects. These are thought to provide a social benefit to local communities. Botswana has a mixed economic system with tax revenue as a percentage of GDP at 27% in 2017. Some Botswanan economists suggest that the country should move towards a market economic system, taking care to avoid market failure. 

• Define social benefit. [2] 

• Explain two advantages of conserving natural resources. [4] 

• Analyse how taxation could reduce market failure. [6]

Droughts in the Pacific Coast region of the US and regulations, in the form of limits on the amount of salmon that can be caught in the wild, have reduced the supply of wild salmon. These limits were imposed to avoid market failure in the salmon market. However, the effect of this on the revenue of salmon producers is uncertain. In addition, producers of farmed salmon in the US states of Washington and Alaska have received subsidies from the US government. 

• Explain one market failure that may occur in the salmon market. [4]

The production process in the oil industry is capital-intensive. The pollution it generates means it is one cause of environmental market failure. A Nigerian oil monopoly is starting to produce more environmentally friendly liquefied petroleum gas (LPG), rather than kerosene, in an attempt to reduce pollution. The Nigerian government intends to split the monopoly firm into separate companies to improve efficiency.

• Explain how market failure might occur in the oil industry. [4]

Swaziland is a small African country where six in ten people live in poverty and most firms are small and use little capital equipment. In October 2015 it opened a new airport. Some economists suggest that the building of the airport involved a high opportunity cost and caused a range of external costs. The building of the airport is part of the government’s plan to turn the country from a developing into a developed country. 

• Analyse the external costs that can be caused by the building and expansion of an airport.[6]

More governments are imposing taxes on unhealthy food and drinks. Such taxes are usually regressive. Some of these governments are also increasing their spending on healthcare. In other countries healthcare is provided by the private sector. The number of state-owned enterprises is declining in a number of countries due to privatisation. 

• Explain why the social benefit of healthcare is greater than the private benefit. [4]

Taxi drivers usually have to buy a licence to carry passengers. The relatively high fixed cost of the licence discourages some people from becoming taxi drivers. Encouraging more people to be taxi drivers would be likely to reduce taxi fares and unemployment. It may, however, increase traffic congestion. 

• Explain why traffic congestion is an external cost. [4]
