We used the unobserved component model of Harvey (1989, 2011) to estimate the Phillips curve for the USA and Australia, augmenting it with the oil price. Our results show that while the coefficient of demand pressure and the intercept decreased, the coefficient of the oil price increased. Therefore, the oil price is likely to play a significant role in future inflation rates.
