What is Economics


Economics is the social science that studies the production,distribution and Consumption of goods and services.Economics focuses on the behaviour and interactions of economic agents and how economics work.

Definition of Economics 

The word economics has been derived from the Latin word "Oiko Nomos"
which means household budget. This explains how the persons of a house 
manage to earn money and spend it. Later on this word was usedoing on 
state called "Polos". This explains that how the people of a state use to spend 
their lives and earn means of living. For thisome reasonso it was better called 
as "Political economy". However these two words were separated and become
separate disciplines. The first one become political science and later one the 
subject of economics.



Evolution of Economics 

The evolution of the definition of  economics has passed through various stages.
However it can be broadly classified into three school of thought.

(1) Classical school of thought              (1723------1790)
(2) Noe-Classical school of thought     (1842-------1924)
(3)London school of thought 



J.M.KEYNES'S Definition

Keynes in his book "General theory of employment, interest and money"
published in 1936 gave a modern definition of Economics.

"Economics is a science which creates employment opportunities and from

The purpose of every economic effort of the human being should be the 
material walfare. So Economics relates to that part of wealth which is 
concerned with the ""material walfare".

Our common observation is that; with the change in the price o

Basic Tools Of Mathematics And statistics In Economics

Modern economists consider the use and help of fundamental mathematical  tools to discuss the relationship of various quantities in economics very fruitful. In view of the importance of such relationships we study the following concepts: Variables Generally the quantities which change their values are known as "Variables". It can be well defined as under: "A variable is a magnitude which is measureable and taken of different values" According to Prof. Kooros "A variable is a symbol which during a discussion may assume different values or a set of admissible values". E.T. Dowling defines variable as under: "A variable ranges over a set of possible values within a given problem". In normal life Time, Temperature, Speed of a vehicle are regarded as variables. In economics there are many quantities which also change their values e.g  Income, Consumption, Saving , Investment, Price, Demand, Supply, Utility etc. In ma
