Science of wealth

Adam Smith (father of economics) definition of economics:

In f 776, in his book "An inquiry into the nature and causes

of the wealth of nations"

"a science which inquires into the -nature and causes of wealth of nations"

Science of wealth definition has two dimensions.

1-Definition of wealth, and

2-Causes of wealth

Meaning of wealth

Around the industrial revolution, merchants were the most powerful class in Western Europe, and wealth for them meant money only.

Sin money at that time was in the shape of gold, merchants declared gold as the only wealth.

Activities which did not result in production of material goods production were unproductive.

Causes of wealth

Human being are born selfish

They have self-interest

It is not the benevolence but self interest that guides economic activity

so left to themselves , each individual would maximize his self intrest (wealth / economic)

When all the  adults of the nation maximize their self interest the wealth of nation grow the faster.

Adam Smiths Definition

Production and growth of wealth as the subject matter of economics.

Wealth is preferred over human.

He considered how individual prices are set and prices of land, labor, and capital are determined

Economic benefits come from self-interested action of individuals.

Criticisms on Adam smith definition

considered economics as a dismal OF selfish science.

defined wealth in a very narrow and restricted sense Which considers only material and tangible goods while ignored the services of a doctor and teacher etc.

Have given emphases only to wealth and reduced man to secondary pace in the study of economics.

Adam Smith emphasis only to earn the wealth.

Wealth is more important the human welfare.

Science of Welfare by Alfred Marshal

Adam Smith’s prophesy that  self-interest would be beneficial to all did not materialize after the industrial revolution.

The revolution divided the society into haves and have - not -including unemployed.

Marshal attempted to offer a compromise and a new definition of economics as

“a study of mankind  ordinary business of life its examines that part of individual and social action which is most closely with the attainment and with the use of material requisites of wellbeing . Thus it is one side a study of wealth; and on the order and more important side, a part of a study of man”.

Main Point of Marshal Definition

  • It studies daily life of ordinary human beings.(rich + poor)
  • Economics is not a useless study of wealth or wasting time exercise BUT
  • It has aim to find out how wealth promotes human Welfare.
  • Wealth is not as importance for the economists as the man himself.
  • The objective of the study of economics is not wealth but behavior and activities to produce and consume maximum number of goods and services.
  • Economics a science which discuss only the people in society not isolated individuals.

 Drawback of Marshal Definition

  • Marshal definition was comprehensive and powerful but had few drawbacks like:
  • It does cover all economic problems. Discuss only material things while ignores
  • Welfare is idea ….
  • Welfare is not measurable.
  • Question of Moral judgment arises.

Criticism on Marshal Definition

  • Economics is not restricted to material good only, non-material things like health, education, entertainment etc.
  • welfare is subjective and form person to person
  • Concept of welfare is vague and not clear.
  • It differs from place to place and people to people.

 Science of Scarcity……Robins definition

In t 93 1, in his book "nature and significance of economic science" as “economics is a science which studies behavior as a relationship between ends and scarce means which have alternative uses”

"ENDS"……. refers to human wants………which are unlimited and hence {main has to make a choice of

more urgent and least urgent wants.

Economic is also called a science of CHOECF.

 

Resources to satisfy unlimited wants are scarce/limited except few.

Resources have alternative use.

Had the resources been unlimited, there would have no economic problem.
