These concepts or elements includes<\/p>\n<ol>\n<li>\n<div>Wants: this is the desire or needs of man to own goods and services that give satisfaction. These wants are insatiable because the resources needed to cater for them are limited (in short supply). The basic need or wants of man are food, clothing and shelter.\n<\/div>\n<\/li>\n<li>\n<div>Scarcity: this refers to the limited supply of resources needed to meet (satisfy) wants.\n<\/div>\n<\/li>\n<li>\n<div>Choice: this is the system employed in selecting one need to satisfy out of a number of alternatives.\n<\/div>\n<\/li>\n<li>\n<div>Scale of preference: is a list of unsatisfied wants in order of importance. This is relative to the individual\n<\/div>\n<\/li>\n<li>\n<div>Opportunity cost: is the satisfaction of one want or need at the expense of another. It is expressed in terms of the value or worth of forgone alternative. It is also referred to as the true or real cost while money cost is the amount spent in order to acquire a particular good or service.\n<\/div>\n<p>\u00a0<\/li>\n<\/ol>\n<p><strong>PRINCIPLES OF DEMAND AND SUPPLY<br \/>\n<\/strong>Demand: Demand may be defined as the quality of goods a consumer is willing and ready to buy at a given price over a given period of time.
