Flattening of the Phillips Curve and the Role of Oil Price: An Unobserved Components Model for the USA and Australia

  • Paradiso, Antonio
  • Rao, B. Bhaskara

We use the unobserved components model of Harvey (1989 and 2011) to estimate the Phillips curve (PC) for the USA and Australia, by augmenting it with oil prices. We found that the level coefficient of inflation and the coefficient of demand pressure have declined and contributed to the flattening of the Phillips curve. But the coefficient of oil prices has increased and has partly offset these effects. Therefore, oil prices are likely to play a significant role in future inflation rates.
