One of the consequences of ·the accelerated demand and the over valuation of the peso was the de-substitution of Imports In all types of goods. The participation of Imported products Increased from 1970-1980 from 7 to 131 In consumer goods. from 18 to 251 In Intermediate goods. and from 47 to 551 In capital goods •. This phenomenon was caused baslcal ly by four factors: a) growth of demand; b) lack of ·capacity of the Industrial plant; c) lower prices of foreign products due to the over valuation of the natloanl currency; and d) avallaqlllty of foreign exchange from the export of energetics.

Since national exports consist primarily of energetics, the deficit corresponding to non-pegroleum products multiplied six times during the same period. reaching a figure of approximately 13,000 million dollars In 1980.
