Inflation and inflation uncertainty in Argentina, 1810-2005

Unit root tests results suggest that inflation in Argentina for the period 1810-2005 is a stationary series when account is taken of structural breaks that coincide with bouts of hyperinflation. A GARCH (1,1) model of annual inflation suggests a positive short-run relation between the mean and variance of inflation, supporting Friedman's hypothesis that high inflation is associated with more variable inflation.
