| Abstract: | This paper identifies two competing accounts of recent US macroeconomic performance, both of which are capable of explaining the concurrence of low unemployment and low inflation experienced by the US after 1995. Econometric evidence provides partial support for both views, establishing that while there has been no change in the position of the long run Phillips curve in the US during the 1990s, this long run Phillips curve is likely not vertical. These results suggest that recent US macroeconomic performance is not sustainable and that US policy makers ultimately face a choice between higher unemployment or higher inflation in the long run. |
