Desire of getting more and more is in the nature of human beings. We all know that resources are limited; it is not possible to fulfil our all desire. Resources are limited in a sense that one cannot have as many goods and services,as one can wish for the satisfaction of wants.

Economics is an academic discipline and social science that studies the economic behaviour of the people. Economists analyse how an individual and world distributes limited resources to satisfy unlimited wants, monitors economic trends and forecasts economic conditions.
