For the range of "small" government deficits for which two stationary solutions exist, an increase in the deficit reduces the long-run rate of inflation if the locally-stable (high inflation) stationary equilibrium is chosen, increases it if the locally- unstable (low inflation) equilibrium is chosen. Explosive, unstable behavior always involves a steadily increasing negative rate of inflation, i.e. a "hyperdeflation." There always exist deficits so large that stationary solutions do not exist. Behavior then is unstable and explosive: hyperinflations are ruled out and hyperdeflations must result. Empirical studies of hyperinflations should no longer use the rational-expectations version of the Sargent-Wallace model as a theoretical backdrop. Copyright 1987 by Royal Economic Society.
