Revival of classical political economy: An exposition

The purpose of this paper is twofold: first, to discuss the theoretical foundations and policy implications of two of the offshoots of modern macroeconomics viz., supply-side economics and rational expectations; and second to evaluate the recent development of thinking in macroeconomics. Thereby it tries to bring forth the current state of macroeconomics, although the term “current” itself is a difficult term to define as the only constant thing is ‘change’, more so in case of an evolutionary science like economics. While highlighting the celebrated classical-Keynesian debate, it thoroughly examines the supply-side economics and rational expectations hypothesis with due importance to their practical application.
