If aspirants preparing for UPSC Civil Services Exam are confused about one particular subject, that is Indian Economy! Candidates are doubtful about the approach and study-materials for Economics section of IAS Prelims and Mains. They keep on asking about the single, all-in-one-book to cover Economics.
Textbooks do exist, but unfortunately, as Economy section for UPSC exam is more current affairs based, no one can guarantee any text book as complete. Ideally, one should have atleast one book on Indian Economy plus the latest economic survey. Also, the latest budget should be properly analysed. Economic and Political Weekly (EPW) is a magazine which can be suggested as a good read. The best way to start is by understanding basic concepts, thinking and asking questions.
