In 2020, Singapore experienced a decrease in both its population size and its labour force. 2020 was a year of great change in a number of Singaporean markets. Some moved from disequilibrium to equilibrium. Despite all these changes, Singapore managed to increase its exports of goods and services.

In Greece, rich households spend more than the average household. The amount of spending in an economy influences whether its production point is on or inside its production possibilitycurve (PPC). In 2020, household spending in Greece fell. This affected some firms’ plans to merge. It also increased unemployment. More than half of those unemployed in Greece had been unemployed for more than a year.

Global spending on the health sector, by both the private and public sectors, is the highest compared with all other sectors including education and defence. Investment in education and the health sector has resulted in new life-saving technology being introduced. However, demand for certain vaccinations has decreased over the years, shifting the demand curve of vaccinations to the left.

Sweden has a mixed economic system. In 2018, it was operating at a point inside its production possibility curve (PPC). In 2018, the country’s schools employed nearly 2500 extra teachers. A few of these had previously been actors. A higher number had previously been government officials involved with regulation of Swedish monopolies.

Russia’s birth rate fell by 11% in 2017 to its lowest level for a decade. Over the next 30 years, Russia’s population is forecast to fall from 144 million to 107 million. The government announced measures to reverse this decline in population. In 2017, it also announced privatisation plans and measures to reverse a decrease in investment which could lead to a fall in the quantity of capital goods. Privatisation can reduce monopoly power in a market.

Mexico has a history of trade deficits. The government is moving the economy closer to free trade, to try to improve its macroeconomic performance. It was predicted in 2017 that Mexico’s economy would experience a small rise in its unemployment rate. In 2017 the economy’s inflation rate was 6.6%, the highest rate since 2001. A number of policy measures may be used to reduce inflation, including increasing the rate of income tax.

South east Asian countries have reduced tariffs between themselves through the ASEAN Free Trade Agreement. ASEAN member countries are also removing non-tariff methods of protection. The intention is to raise economic growth through more international trade. This should enable small and medium-sized firms in ASEAN countries to grow and increase their exports.

Ireland has one of the lowest rates of corporation tax in Europe. This has encouraged many multinational companies (MNCs) to produce in Ireland. Other reasons why firms want to produce in Ireland include access to freer trade with other European countries, higher labour productivity and government grants.

In 2017, the Japanese government announced improvements to its tax system. The amount of tax raised is influenced by the size and age distribution of a country’s population. Japan’s birth and death rates are falling, its population is ageing, and it has low immigration. Overall, Japan’s population is decreasing.

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.

The main industries in the Seychelles, an island country in the Indian ocean, are tourism and fishing. The price elasticity of supply of fish is affected by the relatively short time that fish can be stored. Economic goods and free goods play a role in both fishing and tourism. With rises in the skills of workers and an increase in enterprise, GDP per head has increased by more than seven times over the last fifty years.

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.
