The study of how people satisfy unlimited wants with limited resources is called Economics.
Economics studies the production, distribution, and how people consume products and services in a determined market. Economics based its studies on the belief that resources are limited but people in a society have many wishes, desires, wants, and needs. So Economics studies all the factors involved in the process of getting raw materials and natural resources, fabrication, supply, delivery and the prices people pay to get something they want or need.
