Forbes Inflation Unemployment Phillips Curve Trade-off

  • Inflation is likely to remain mild in the next two years, but first a caution: none of the inflation forecasting models is doing a good job these days.
  • the Phillips Curve was our primary way of looking at inflation. William Phillips found an inverse relationship between inflation and unemployment over the period 1861-1957. This simple approach was used here in the United States in the 1960s and 70s.
  • With lower unemployment you would expect greater inflation. However, the Phillips Curve does not explain why inflation didn’t go down much when our unemployment rate was high a few years ago.

  • Milton Friedman said “Inflation is always and everywhere a monetary phenomenon . . . .” The relationship was solid for a long time, though financial changes in the 1990s made the theory harder to apply.
  • Unfortunately, the expectations-augmented Phillips Curve has not worked well in recent years. One study found that the predicted inflation for 2010 was negative 4.3 percent, while actual inflation was still positive.
  • Different theories tell us that the actual dynamics by which inflation changes are influenced not only by unemployment but also by inflation expectations.
  • Two different money concepts have been used, the money supply (such as the M2 definition) and the monetary base Recent data for both concepts indicate that inflation should have been much higher in recent years. The fact that inflation has accelerated very little suggests that in the current environment, the money-inflation connection is not very tight.

    This article from Forbes is primarily titled to be a forecast about inflation in the coming fiscal year but it also interestingly (and relevant to our studies) discusses the different arguments and criticism surrounding the modelled Phillips Curve. The article also contains an interesting graph that is based on recorded statistics about inflation and unemployment which helps to demonstrate the problems with the Phillips Curve model.
