Principles of Economics is a comprehensive textbook for undergraduate and postgraduate students. The book begins with a simple introduction to economics as a social science, moves on to basic economic problems of individuals, firms and the society focusing on the problem of scarcity and choice, and finally discusses the higher levels of economic theories.\n\nIt will be of immense value to students of economics, BBA, MBA, and those preparing for professional and competitive examinations such as IAS, IES, CA, ICWAI and CS. Students of engineering and medical courses who have virtually no prior subject knowledge and have to clear an economics paper will find this book a boon.
