The distinguishing feature of the book is that it applies the standard Keynesian macro-models, developed elaborately in Part I of the book, to analyse India's macroeconomic experiences in the post-Independence period. It covers the Mahalanobis era of planned economic development from 1950-51 ? 1990-91. It, then, moves on to the post-reform period, that it has divided into two sub periods: 1991-92 to 2013-14 and 2014-15 ? 2024-25. All through this post-reform period, the book, with tell-tale evidences drawn from authentic sources, argues using formal frameworks that the external factors such as capital inflows and export demand played the most important role in determining India's macroeconomic performance. In addition, during 2014-15 ? 2024-25, the policy of Demonetization, introduction of GST, banking sector reforms induced by widespread bank-frauds and the pandemic caused by the COVID-19 produced strong deleterious impact on the economy. Finally, the book analyses threadbare Trump's tariff policy and seeks to unravel its plausible impact on the global economy in general and that on India in particular.
