I suggest if you are not focussing on India per se, but want to understand details of a sector in & out, plz surf through World Bank's website (www.worldbank.org
). Here you can find excellent studies done by worldbank as well as other worldbank associate institutions.
However, if ur concern is more from India's study, you can get valuable information from sites of Indiainfoline, Crisil, IDFC etc.
For more general reading however, I strongly recommend Mckinsey Quarterly. You can become a free member, though the artciles available for free membership are quiet few. Try!!!
