The purpose of this unit is to define the subject matter of economics, highlighting what constitute the central (essential) problems of an economy. The normal tendency is to start with a definition. However, in introducing the subject called economics, starting with a definition is an extremely difficult task, if not impossible, since there exists no single accepted definition. You will be surprised if we tell you that there are as many definitions of economics as there are number of economists in this world. Each will claim that his or her definition is superior and more relevant and appropriate than that of others. Hence there is a dilemma as well as an ego problem. However, to do justice to the beginner students who will be reading our unit in economics, we have to start with an analysis of what the subject of economics is all about. It is in this context that we choose Lionel Robbin’s definition of economics in preference to Adam Smith’s, Alfred Marshall’s or J.M. Keynes’.

According to Lionel Robbins, “Economics is a science which studies human behaviour as a relationship between ends and scarce means which have alternative uses” [An Essay On The Nature And Significance Of Economic Science 1933].

The starting point of economics is human wants, needs and desires. Human beings living in any society at any stage of historical development of that society have wants and needs. Some of these needs like the need for food, clothing, shelter are biological in character, needed to sustain life in this universe. The origin of needs is, therefore, biological. However, the majority of human needs arise from the fact that people live together in a society. It is the existence of human society, which accounts for a large chunk of our needs. Such needs are determined by a complex set of factors called the culture of a given society. Even biological needs (like food) are also influenced by the culture of the society at any particular stage of historical development of that society. Hence, we find that the origin of needs is the biological necessity of sustaining life, while the existence of human society would determine its form, nature, and structure. One important characteristic of...
