Definition, Scope and nature of Economics


Nature And Scope Of Economics
Economics is science which studies the life of people living in a country or in the world as a whole. What is the economic life of the people or in other worlds, what is economics?  To answer  this question we have to analyze the definition of economics which is given below

DEFINITIONS OF ECONOMICS:
   There are three well-known definitions of economics
(i)  Definition of economics given by the classical School of thought led by Adam smith.
(ii)   Definition of economics presented by the Neo-Classical school of thought led by Alfred Marshal.
(iii)  Robbin’s  definition of economics.
  We now explain. One by One, the definitions referred above

ADAM SMITH ‘S DEFINITION OF ECONOMICS:
     Adam smith wrote a book in 1776 entitle “The wealth of Nation” in this book he discussed the word “WEALTH” through its four aspects  i.e.  production of wealth.exchange of wealth, distribution of  and consumption of wealth. This clearly means that, according to Adam smith, Economics is a science of wealth.
         To analyze this definition we will diacuss the word “Wealth” and its four aspects. Wealth means goods and services transacted with the help of money, it is a matter of common observation that the transaction of goods and services  (wealth) takes place in our day-to-day life. But the question is : Why and how is the transaction of goods and services taking place?  To know the answer of this question we are require d to look into four aspect of wealth.

(1) PRODUCTION OF WEALTH: This means the production of goods and services by combining four factors of production  i.e. land, labour, capital, organization or entrepreneurship. Land is the natural resource such as soil, sea, minerals, livestock, forests etc  labour is a mental or physical work which is done for  the sake of reward . capital means manmade resources which help to produce goods and services. Whereas organization is the act of combining four factors of production to producing and marketing of the goods and services for the  sake of profit hence. Production of wealth means production of goods and services.

(2) EXCHANGE OF WEALTH: Entrepreneurs usually produce more goods and services than their own requirement s. Why do they do so?  Simply to get  their surplus produce exchanged in the market with the surplus goods and services produced by others. The process of exchanging of wealth continues throughout the year and as a result people get the goods and  services produced for each other. This enables everyone in the society to satisfy his multiple wants.

(3) DISTRIBUTION OF WEALTH: As a result of exchange of wealth in a country whatever falls to the lot of each individual or a section of society is called his or its share in the national wealth produced in a year. If the share of certain section of a society in the national wealth is bigger than that of other this will be the unequal distribution of wealth in a country. If all section of the society are enjoying  all goods and services being  produced in the country it will be fair and equal distribution of wealth.

(4)CONSUMPTION OF WEALTH: The ultimate objective of production, exchange and distribution is the consumption of wealth.  When people get their share from the national product they use it to satisfy their wants hence , the using up of the utility of goods and services for the satisfaction of wants  is known as the consumption of wealth .
     Thus, from the above explanation of wealth and its four aspect, it becomes clear that services available to the society. Beside this he also explain as to why and how wealth is produced, exchanged, distributed and consumed.

CRITISM ON THE DEFINITION:
          During the late 18th  century religious sentiments of the people were very strong and spiritual values held sway over man’s mind therefore. It was difficult for them to accept economies as a science which teaches materialism. They raised hue and cry against it. Especially the two men of letter. Carlyle and Ruskin , condemned it. They said that economics as a science of materialism is just  “a science of bread and butter”. They also termed economics as a” dismal science” as, according to them it promotes selfishness and greed. They thought that if economics was thought. The science of materialism will take mankind away from spiritualism. Hence, Carlyle even went to the extent of saying that economics is “a pig philosophy “   the  two literary figures therefore held that spiritual values as love. Sincerity , sacrifice, friendship, brotherhood, etc,  be promoted through religious in place of materialism being taught in economics.
             Regardless of what critics had been saying about Economics, the criticism was not justifiable at all. The reason is that they saw only the negative side of the picture, since everything has its pro’s and con’s and economics is no exception to it. However, gradually people discovered through observation and experiments that economics helps them to eliminate poverty. Raises their standard of living and turns them human beings. Hence , they soon realized material that wealth plays a vital role in their life.

ALFRED MARSHALL’S DEFINITION OF ECONOMICS
                   Marshall is a well-known economist. He was behind Smith and for him all the way, approximantely hundred twenty years after Smith’s book on Economics. Alfred Marshall wrote a book in Cambridge which was entitled “PRINCIPALES OF ECONOMICS”.
In this book, Marshall defined Economics as an instrument to remove the doubts of the people regarding the subject.
            Marshall stated , “Economics is the study of mankind in the ordinary business of life; it examines that part of individual and social Action which is most is closely connected with the attainment and use of the material requisites of well-being”
From the definition,  we able to achieve three main points:
  (i) Ordinary business of life or Economics as a social science.
  (ii) Attainment and use of material requisites or production and consumption of wealth.
  (iii) Well-being or welfare of the society.

(i) ORDINARY BUSINESS OF LIFE OR ECONOMICS AS A SOCIAL SCIENCE:
            According to Marshall, Economics is studies the economic behavior of the people living in the society. Economic activities of the people outside the society are not, therefore, considered in the study of economics. Hence Economics does not study the isolated individuals or any “Robinson Crusoe”. By thie he show that economics is asocial science.

(ii) ATTAINMENT AND USE OF MATERIAL REQUISITES OR PRODUCTION AND CONSUMPTION OF WEALTH:
        In the ordinary business of life, human beings perform different types of activities such as political activities , sports, economic activities , moral and religious activities, of all these activities of ordinary life, Economics Studies only those activities which are related with the attainment and use of material  requisites or in other words, the production and consumption of wealth. So far he is of the same view as that of Adam smith that Economics is a science of wealth.

(iii) WELL BEING OR WELFARE OF THE SOCIETY:
         According to Marshall, the objective of the study of Economics is to promote the material welfare of the people, to Marshall. Economics focusses on only material aspects of life and therefore studies material requisites well-being. Hence, according to him economics does not regard wealth to be the goal of all human activities. Instead, it is only a mean to achieve an end and that end is the economic welfare of the people or the raising up of the standard of living of the people, Particularly of the poor, So that they may lead a better economic life.

CRITICISM ON MARSHALL’S DDFINITION:
        In 1931, another economists, Loinel Robbins, wrote a book entitled “NATURE AND SIGNIFICANCE OF ECONOMIC SCIENCE” In this book he criticized Marshall on the following grounds,

   (1) THE DEFINITION NAROWS THE SCOPE OF ECONOMICS: The use of the word “Material” by Marshall narrows the scope of economics as well need both the material and non-material requisites of life i.e. goods and services.
      The need for non-material requisites is certainly over-whelming , Examples of the nonmaterial requisites are the service of lawyers , teachers and doctors etc, these non-material requisites satisfy our wants in the same way as material requisites (or goods) and if we exclude them from the study of economics, the scope of economics would certainly be restricted.

(2)  WELL BEING IS A NONMEASURABLE CONCEPT: True enough in its meaning one cannot measure “wellbeing”. It is something that cannot be estimated to figures , although it can be stated in theories. Thus, according to Robbins, well-being cannot be measured as stated by Marshall.

(3) ECONOMICS SHOULD NOT PASS VALUE JUDGEMENT: According to Robbins, Economics should emphasize only on human and their satisfaction and, therefore it is not concerned with whether these wants are being satisfied buy good things or bad things. For example, human beings needs food clothing and shelter and they are essentially required to be provided, but as far as wants for alcoholic drinks, cigarettes and gambling are concerned, they are also required to be satisfied according to Robbins as people are ready to pay for them  disregarding the welfare aspect of these things, thus what Robbins is trying, is “just satisfy wants and don’t bother whether they are for the better or the worse”

(4) IT CREATES PROBLEMS FOR POLICY MAKING: According to Marshal, the study of economics should be directed to pursue the concept of welfare, but Robbins objects to this point of view on the ground that the concept of welfare would place the government in a vulnerable position in the making of economic policies, For example , some people may object to the production of alcohol and cigarettes on the ground that these things retard welfare, but other might say that they want these things for the satisfaction of their wants and are ready to pay for them. Thus the question of liking of some production on the basis of welfare will create problem for the government in the farming of economics policies.

ROBBINS DEFINITION OF ECONOMICS
             Robbins says, “economics is the science which studies human behavior as a relationship between ( multiple ) ends and scare means which have alternative uses”. this definition points out the problem of scarcity and choice in the economic life of the people. Three main points of the definitions are…..
    (i) Multiple ends.
   (ii) Scare means.
   (iii) Alternative uses.
(i) MULTIPLE ENDS: Multiple ends means “no limit to wants”. Human wants or ends are unlimited. They keep on rising or they rise again and again. This means that they do not come again in the evening. Same is the case of wants for radio, t.v, and furniture etc. we always want to replace them with the new and better ones. Since human wants are unlimited , one is compelled to choose between more urgent and less urgent wants which makes economics a science of choice. Hence multiplicity of ends calls for ceaseless efforts for their satisfaction. therefore, never ending cycle of economic activities moves on.
(ii) SCARCE MEANS: There may be no limit to human wants, but the means to satisfy them are definite. The means of resources can be divided into two parts. Firstly the resources in the production sector of the economy i.e. land, labour, capital, entrepreneurship are quite limited because the price of these four factors of production are determined in the market. Secondly, the consumer goods and service produced as a result of the combination of the four factors of production are also limited because they are also priced in the market. This means that resources are limited in the sense that one cannot have goods and services as he wishes for the satisfaction of wants. There is definitely a limit to it.
         Money income represent command on the real resources available in the form of goods and services. Higher the income. Higher will be the available of real resources and vice versa. Since income are always limited, money resources are also limited.
(iii) ALTERNATIVE USES: The third point gathered from Robbins definition is the “alternative” use of resources. What Robbins meant to say is that there are many ways of using the resources. It is always up to the person concerned to give priority to his/her basic wants. For example, a person has got Rs. 1000. With this amount of money he is able to do anything within this limit. He can buy clothes, entertain friend or dine outside with his family, but being a rational human being. He will chose the most optimum use of his limited resources. Supposing, he buys clothes only and postpones the fulfillment of all other wants. This would mean that he has satisfied his want for clothes as an alternative to all other wants which could have been satisfied by an expenditure of Rs. 1000/.
           This is exactly the way all human being pass their life. It gives a clear image of the economic life of the people who are always faced with the problem of scarcity of resources and choice between ands and are forced to make the alternative use of resources.


MERITS OF DEFINITION

(1) COMPREHENSIVENESS: Robbins definition reflects the realities of life. We all know that human wants are unlimited and the available resources are limited and all use are making the alternative use of resources. This means that all human being are faced with the problem of scarcity and choice. Thus Robbins’ definition clearly identifies the existence of the economic problem in a most comprehensive manner.

(2) EXTENSION OF THE SCOPE OF ECONOMICS: Unlike Marshall, Robbins brings into focus not only goods but also services required to satisfy human wants. Not only this, Robbins also establishes that Economics as a science is natural between good wants and bad wants. According to him, “Economics can no longer be regarded as a “dismal science” because it takes no responsibility on selecting the end”. In this way, he extended the scope of economics

(3) ANALYTICAL IN NATURE: Robbins definition of economics helps to analyze the economic problems of people and therefore paves a way for their solution. Keep in view different sectors of the economy so that a larger number of goods and services are produced. This analytical approach can solve the economic problem of the people as far as possible

DEMERITS OF THE DEFINITION

(1) ROBBINS HAS TRIED TO MAKE ECONOMICS A PURE / POSITIVE SCIENCE: Whereas it is social science because it deals with the behavior of the human being In pure science. Whatever is stated today will definition be true two centuries later. For example, two molecules of hydrogen and one of oxygen will always make water and two plus two will always be four etc. but, as for as human behavior is concerned it keeps on changing from time to time. Moreover, there is no laboratory to test the human behavior as in the case of matter in the physical science like physics and chemistry. Thus, it is undesirable to define to economics in line with pure science.
(2) Marshall defined economics as an engine of social betterment. In this way, Marshall was more concerned with the welfare of the people. Robbins on the other hand, deals with ends, means their alternative uses. Thus, Robbins gave secondary importance to the crux of the subject i.e. The human being, in other words, Robbins has made economics a theory of value whereas it is something more than that.

(3) There is no touch of morality in Robbins definition of economics, for example, according to Robbins a society can produce anything which required to satisfy human wants. But, there is no justification for the production of drugs, alcohol drink and the services of prostitutes because the use of these goods and services disrupt the whole social set-up. Thus, Robbins has separated Economics from its moral basis.

(4) Robbins says that resources of all kind are limited. But, in the production sector of the third world countries we fine that human resources in he from of labor are not limited. This is so because laborers are available free of any reward in these countries due to their problem of massive unemployment.

(5) Robbins says that resources are limited and, therefore, he overlooks the fact that the limited resources can be increased. The economics of growth and development has shown the ways by which limited resources can be increased.

CONCLUSION
           Economics is a social science which deals with the economic thinking of human beings. Human being are imperfect and so is their thinking, thus, there cannot be any exact and perfect definition of economics. One has got to accept the definition even though they have demerits.
