Перевести текст areas of economics there are three main dimensional approaches to economics: microeconomics, macroeconomics and development economics. microeconomics focuses on individual economic units. the economic behaviour of either individual consumers or firms or whole industries is studied by microeconomics. the distribution and consumption of products and income received among all these units is also analyzed by microeconomics. in this field of economics individuals are considered both as suppliers of labour and as consumers of goods. firms are also studied both as suppliers and as consumers of labour and capital. there was a long period in the 19th and in the early 20th centuries when microeconomic questions dominated in the national economics. in the 20th century economists’ interest in forces that affect income, employment and prices grew. and they considered economy in all its relationships. the term “macroeconomics” was first used in the 1930s. the world political and economic depression that began in 1929 required the study of such macroeconomic questions as achievement of full employment and economic growth by means of proper government policies. this area of economics was developed by the british economist john maynard keynes. the third main field of economics - development economics studies the factors of economic growth, and how these factors are used by governments in order to achieve high living standards in the country.
