- Abstract:
- In a recent issue of this journal, Richard Reichel (2004) takes issue with the resurrected Phillips curve (PC) in William Niskanen's (2002) article. Accordingly, Niskanen's reformulation of the PC provides empirical evidence for a weak, but statistically significant, short-run (in the same year) tradeoff between inflation and unemployment rates in the United States. Furthermore, the unemployment rate is directly and significantly determined by the one-period lagged value of the inflation rate, which implies an upward sloping PC, consistent with the type of PC explicated by Milton Friedman (1987). Reichel's main point of contention is that the variables in the reformulated version of PC are nonstationary, meaning that statistical properties (such as conditional mean and variance) vary with time. Thus, Niskanen's findings are spurious.
