Following are the arguments in favour of economics being a positive science:-
1. In economics, the actual viewpoint can provide systematic, logical and correct economic conclusion, because the basis of relationship between causes and consequences is logic itself.
2. Actual viewpoint can form strong economic principles on the basis of actual beliefs and scientific analysis.
3. If only the study of authenticity of economic activities is done in economics, then the disagreement amongst economists will lessen, understanding will increase among them and the development of economics will also take place in a rapid way.
4. Prof Robbins has said that realizing the scarcity of resources, man should work in accordance with his superior skills. He should perform only those works in which he specializes. If human beings begin to perform all tasks, he will waste both his time and money. Hence, economists should limit themselves to the study of cause and effect. What is appropriate, what is not, should be of no concern to economists.
