Starting from the fundamental premise that money is a zero-sum game as every financial asset creates a liability and vice-versa, this book turns monetary theory on its head. By theorizing from first principles and employing rigorous empirical methods, we show that: (i) a loan creates a deposit and not vice-versa, (ii) banks create money but not NBFCs, (iii) the theory of the money multiplier is incorrect, (iv) bank reserves cannot be lent as bank loans, and (v) the “crowding-out” effect depends on whether the government borrows from banks or from households and corporates. We derive a comprehensive equation that describes all the determinants of money, called the V-S equation, to capture the essence of money in an economy.

He authored three Economic Surveys of India that introduced new policy frameworks emphasizing ethical wealth creation, supply-side reform, and public-investment-led growth. The thematic Surveys—a departure from past practice—were widely discussed within government, cited by senior political leadership for reshaping the policy discourse, and continue to guide India’s economic approach, illustrating how first-principles economic analysis can inform large-scale reform.

He has also engaged extensively with the public to improve economic literacy by communicating complex ideas in accessible ways while remaining grounded in scholarly rigor—efforts that have led to him being described in the media as “the common man’s economist.”
