DEFINITION AND MEANING OF ECONOMICS

Economics as a dynamic subject has very many definitions. It is often said that there are so many definitions of economics as there are economists because they see the subject from different point of view.

Some definition given by some economists includes:
Adam Smith (18th Century British Economist and Called “Father of Economics”) in 1776 defined economics as “an inquiry into the nature and causes of the wealth of nations”.
John Stuart Mill in 1843 defined economics as “the practical science of production and distribution of wealth”
Alfred Marshal in 1890 defines it as “a study of mankind in the ordinary business of life, earning and enjoying a living”.
H. J. Daven Port defines economics as “a science that treats phenomena from the stand point of price”.

Edvins Canon defines economics as “the study of things having to do with man’s material welfares”.

A.I. Pigou defines economics as “the study of how total production could be increased so that the standard of living of people might be improved’’.
However, the most acceptable and widely used definition was by Professor Lionel C. Robins in 1932, which defines economics as “the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses”. The reasons for the popularity of this definition is twofold, namely, it is the only definition which mentions:
(a) The basic economic problem of scarcity and choice.
(b) The fact that economics is a social science.

THE SCOPE OF ECONOMICS

1. Economics relies on the findings of other social sciences which include ethics, political science, sociology, geography, psychology, philosophy, anthropology, etc, in order to reach sound conclusion concerning human behaviour. This inter-relationship with other social sciences promotes a wider general understanding of social behaviour.
2. Economics is a social science which studies human behaviour or mankind’s economic activities in relation to production, exchange, distribution and consumption of goods and services.
3. It deals with how people react to economic situations and how they behave while engaged in their daily economic activities.
4. Economics deals with the administration of scarce resources in the society.
5. Economics is positive in its study of human behaviour by concerning itself with “What is’, and not normative with “What should be’, and thus point out the full cost – the real or opportunity cost – of achieving our ends.
