Finally, I read the book "Fault Lines: How Hidden Fractures Still Threaten the World Economy" by Professor Raghuram Rajan. Its a wonderful book. All those interested in understanding the global economic issues and challenges should read it at least once. He gives great narrative in each chapter in the beginning and good summary at end.
The chapters I enjoyed reading are chapter 2 and chapter 9.
The full introduction chapter is freely available here.
