Brazil is a country of continental proportions whose gross domestic product is unevenly distributed among its various regions. The impact of general domestic economic policies has often been perceived as not being regionally neutral, but as reinforcing the geographic concentration of economic activities. This detailed book examines the regional impact of such general policies as: industrialization, agricultural modernization, privatization, stabilization, science and technology, labor, and foreign direct investment. Written by recognized and respected scholars, this book fills a significant gap in the current literature on regional development in Brazil. Researchers and students in economics, economic history, political science and regional studies, and others interested in the economics of transition to a market system will find this comprehensive collection an invaluable resource.
