Computer Prices in the United States and Brazil, 1982–1992 This diagram shows the effective price of computer power in the United States and Brazil. Both prices fell very rapidly because of technological improvements, but the drop in the U.S. price exceeded that of the Brazilian price. The difference between the two prices is a measure of the technology gap between Brazil and the United States in the production of personal computers.
