This book by the Asia Competitiveness Institute introduces a new ease of doing business index that aims to allow for a better approximation of ease of doing business conditions in India's sub-national economies. The approach takes into account three major aspects of doing business, namely (a) Attractiveness to Investors, (b) Business Friendliness, and (c) Competitive Policies. The bottom-up approach considers the various operational issues that firms face at the ground level, with the emphasis being on de facto issues.The analysis provided in the book not only stands up to academic scrutiny as it is grounded in rigorous methodological foundations, but also remains accessible and appealing to policymakers with the co-authors recommending appropriate policy interventions to improve the ease of doing business of India's sub-national economies.
