This book takes a cross-disciplinary look at the financial markets of emerging markets in Latin America. The author wants to disassemble the black box that is the financial market: what are the motivations and interests of the various actors, both institutional and individual?; How do these interact with each other?; How does this information help us understand the Mexican crisis in the 90s and the current crisis in Argentina? The author has conducted extensive interviews with brokers, asset managers, economists, strategists, and analysts in the US, UK, Europe, and Latin America, providing significant material for this study.
