Government Expenditure. Расходы государства
Government' expenditure takes many forms and, particularly over the last 50 years or so, has been a very substantial total. This heading covers spendings by both central government and local authorities. Government spending results in an injection of funds into the circular flow.
Let us take as an example a decision by the Department of Transport to build a new motorway. This will lead to a variety of spending, which would not have taken place otherwise. The authorities will have to employ surveyors, lawyers, accountants and construction workers and will have to purchase large quantities of construction materials. All of the spending generated in this way will be an addition or an injection to the circular flow.
Government spending can, of course, take many other forms. Major financial items are the provision of health and social security benefits. The latter tends to put money directly into the hands of people who need it badly and who are, therefore, likely to spend all or most of it in the near future. If it so wishes the government can use its own expenditure to rapidly affect the level of injections and thus the circular flow. Pursuing such policies, however, can have undesirable side-effects.
Exports. Экспорт
Exports are an injection because they result in income entering the UK's circular flow as a result of the spending decisions of foreign households, firms and governments. Notice that this spending by foreign households is a loss (or withdrawal from) their domestic circular flows.
Britain is a major trading nation and, as such, can be described as an open economy. It exports approximately one-third of all the goods and services it produces. The amount of the UK imports varies but over time will be roughly the same proportion. The UK's trade is recorded in the balance of payments figures, which are published monthly and then collected into annual accounts. If you look at the UK's trade figures you will see that rarely, if ever, does the value of exports equal the value of imports.
The balance of payments accounts are split into two broad sections: the current account, which records imports and exports of goods and services; and the capital account, which records international monetary flows in and out of the UK, such as foreign loans and investment in the UK.
Exports have always been important to the UK economy and are indisputably an engine of economic growth. They provide domestic employment not only in the exporting industry but also in the industries, which supply components and raw materials to that industry. Exports bolster the circular flow and promote employment in a range of industries. They also stimulate innovation and competition and generate a satisfying standard of living. Most of the world's most prosperous economies are successful exporters, notably Japan and Germany. Few isolated economies have been economically successful.
