6. What do you understand by positive economic analysis?

Ans. Positive economic analysis is the study of what or how an economic problem is solved via examining numerous positive statements and methods. In another way, it is also known as a cause-and-effect relationship. It expresses “what is.”
These are true statements that explain what was, is, and will be in the future. These assertions may be examined, proven, or disproven and are free of personal value judgments. For example, if someone states it's raining outside, the truth of that assertion can be checked. It is concerned with real-life or realistic issues. Economic theory is regarded as pure science by economists such as Lionel Robbins. Other instances include India is an overpopulated country with a diversified economy, and so on.

7. What do you understand by normative economic analysis?

Ans. Normative economic analysis is the process of determining whether or not a specific method is good. This analysis focuses on what should be the desired state or how the economic problems should be addressed. It offers economic goals and objectives, as well as what should be done to accomplish them. We come across normative propositions in normative economic analysis that cannot be evaluated because they require human value judgments. It is founded on ethics and deals with idealistic issues.
For instance, the government should support private enterprises to increase the pace of industrialisation, as an illustration of this analysis. Economists such as Marshall, Pigou, and others consider economics to be a normative science.
