Sociologists have outlined three types of economic systems. name each one and give a brief description of it.

The ansewr is "Preindustrial, industrial, and postindustrial economies".

In simple words  pre-industrial is a period before there were machines and instruments to help perform assignments all at once.

Industrial Economics is the investigation of firms, ventures, and markets. It takes a gander at firms of all sizes, from corner shops to multinational mammoths, for example, Wal-Mart or Tesco.

Postindustrial economy is an expression that depicts the move of some major mechanical economies in the late twentieth century from delivering products toward creating and offering services.

The first type of economic system is preindustrial. Its societies generally have an agriculturally based economy, and there is very little technology to provide for the needs of its members. All economic activity is carried out using human labor and animal power. Next there is industrial. This society is characterized by an emphasis on the use of machinery to produce goods. Machines and new sources of energy make the shift from a primary sector to a secondary sector possible. Industrial societies can support lager populations. Last is postindustrial. In this society the tertiary sector becomes the most important area of the economy. Greater emphasis is placed on the collection and distribution of information, which creates a demand for administrative, managerial, professional, technical, and service personnel.
