This book tells the extraordinary story of the Pichet regime's ecomists, kwn as the Chicago Boys. It explores the roots of their ideas and their sense of mission, following their training as ecomists at the Department of Ecomics at the University of Chicago. After their return to Chile, the Chicago Boys took advantage of the opportunity afforded them by the 1973 military coup to launch the first radical free market strategy implemented in a developing country. The ideological strength of their mission and the military authoritarianism of General Pichet combined to transform an ecomy that, following the return to democracy, has stabilized and is seen as a model for Latin America. This book, written by a political scientist, examines the neo-liberal ecomists and their perspective on the market. It also narrates the history of the transfer of ideas from the industrialized world to a developing country, which will be of particular interest to ecomists.
