The real exchange rate appreciated through 1981 and 1982, public sector investment rose 54 percent in real terms from 1979 to 1982, and public sector consumption rose 25 percent during the same three-year period. The combination effectively turned the current-account surplus into a large deficit, as increased spending plus import liberalization practically doubled imports of goods and services between 1979 and 1981. The appreciation also turned manufacturing exports back downward, and a plunge in external prices of primary exports brought them down too. And then the mistake of focusing on the earlier export surplus as the main cause of inflation became clear: the increases in spending led to a leap of inflation despite the return to an external deficit. The rate of inflation went from 59 percent in 1980 to 111 percent by 1983.
