Economics
Economics () is the social science that studies the production, distribution, and consumption of goods and services.
Industry
Industry is the production of goods or related services within an economy. The major source of revenue of a group or company is the indicator of its relevant industry. When a large group has multiple sources of revenue generation, it is considered to be working in different industries. Manufacturing industry became a key sector of production and labour in European and North American countries during the Industrial Revolution, upsetting previous mercantile and feudal economies. This came through many successive rapid advances in technology, such as the production of steel and coal.
Management
Management (or managing) is the administration of an organization, whether it is a business, a not-for-profit organization, or government body. Management includes the activities of setting the strategy of an organization and coordinating the efforts of its employees (or of volunteers) to accomplish its objectives through the application of available resources, such as financial, natural, technological, and human resources. The term "management" may also refer to those people who manage an organization.
Management
In the long-run the workman may be as necessary to his master as his master is to him, but the necessity is not so immediate.
Adam Smith (1776) The Wealth of Nations Chapter VIII, p. 80
Economics
Economics is, in essence, the study of poverty.
Ronald Max Hartwell, The Long Debate on Poverty (1972), p. 3
Management
In the past the man has been first; in the future the system must be first. This in no sense, however, implies that great men are not needed. On the contrary, the first object of any good system must be that of developing first-class men.
Frederick Winslow Taylor (1911) Principles of Scientific Management. p. 2
