The term economic is derived from two Greek words 'Oikou' and 'Nomos meaning the rule or law of the household economics is a originally dealt with the way in which a prudent househlld might best make the most efficient use of the limited income. Ecomomics is a social science; it seeks to answer questions relating to the economic behavior of the people, the society, and the economy. Brief, economics studies the economic behavior of the people. Our activities to generale incom are termed as economic activities, which are responsible for the origin and development of economics as a subject. The oredit of development of economics as a separate subject goes to the classical economist because before 18th century it was considered that econimics was a part of politics, ethics ets. classicists, for the first time defined economics and developed it as an independent and separate discipline. The effective brith of economics as a separate discipline may be braced back to the year 1776 A.D., when the scottish philosopher Adam Smith published 'An inquiry into the nature and causes of the wealth of nations.' There was, of course, economics before Adam Smith.
Nevertheless, Adam Smith wrote the first full-scale trcatise on economics and, by his magisterial in fluence founded what later generations were to call the "english school of classical political economy".
Oriental philosopher kautilya for the first time introduced the theory of economics as a pat of politics.
No on has ever succeeded in neatly efining the difinition and scope and economics. Economists used to say, with Alfred Marshall, the great English economist that economics is "a study of mankind in the ordinary business of life. It examines that part of individual and social action which is most closely connected with the attainment and with the use of the material requisites of welbeing"-ignoring the fact that sociologists, psychologists and anthropologists frequently study exactly the same phenomena. Another English economist, Lionel Robbins, has more recently defiend economics as "The science which studies human behavior as a relationship between ends and scarce means which have alternative uses" This definition-that economics is the science of economizing-captures ore of the striking characteristics of the economist's way of thinking but leaves out the macroeconomic approach to the subject is which is concerned with the economy as a whole.
"Economics is a science of wealth"
The cocept of economics as a different subject was first developed by the scottish philosopher and leader of the classical economists Adam Smith in his book, " An inquiry into the Nature and caused of the wealth of Nations." popularly knowns as, "The science of wealth." published in 1776. The title of Adam Smith's book was inselt a definition of economics.
