"In the first part of this book, with the support of solid theoretical fundamentals and the critical spirit of an analyst with a global economic perspective, José Júlio Senna examines different aspects of the financial crisis and offers us a lengthy discussion of the state of the world economy in the post-crisis period. In particular, he focuses on issues related to the appearance of deflationary forces in the developed world and on the reasons why economic recovery has been so sluggish. The challenges posed to those in charge of monetary policy by the new economic and financial environment receive permanent attention, particularly regarding the Fed. The second part of the book consists of four interviews conducted by Senna with four distinguished specialists on monetary policy.
