The Second Republic is a comprehensive institutional blueprint for India's transition into a developed economy (Viksit Bharat) by 2047. In this book, Ghani, a former World Bank economist and a prominent voice in Indian developmental economics, moves beyond traditional policy debates to focus on the State capacity engine, with his most compelling diagnostic being the two-engine trap. Since the 1991 reforms, India has developed a high-performance private sector engine; however, this is tethered to an obsolete state engine, characterized by nineteenth-century colonial structures and twentieth-century socialist bureaucracy. To address this, India not only needs new laws but a 'Second Republic', a fundamental re-architecting of the state's core institutions to match the dynamism of its people. The book introduces the 4F architecture--functions, finances, functionaries, and foundations--as the integrated mechanism for national renewal, analysing why previous reforms have often stalled. With themes including unlocking the gender dividend (Shakti Superpower), building a modern justice platform, and navigating the geoeconomic frontier of artificial intelligence and climate change, it focuses on the 'plumbing' of the nation: the courts, civil services, and digital systems. A manifesto for 2047, The Second Republic is a timely intervention, shifting the goalposts from 'growth at any cost' to 'growth through institutional excellence', making it an essential read for those trying to understand why India's path to $30 trillion requires more than just capital.
