Chris Dillow says: “It’s widely agreed that the Phillips curve is flat, that low unemployment is not stoking up wage inflation ― though perhaps this has been true for longer than thought.” Perhaps it never has been true.
The fact that the Phillips curve now seems to be flat only tells one that it has been misspecified all along. Thanks to the scientific incompetence of economists this remained undetected since Samuelson/Solow messed things up. The methodological blunder consists in interpreting the Phillips curve as a behavioral relationship. What has to be done is to formulate the Phillips curve as a structural-systemic relationship.
To make matters short here, the elementary version of the correct systemic Phillips curve is shown on Wikimedia.#1, #2 This relationship consists alone of measurable variables and is therefore identical with the observed Phillips curve.
The correct relationship covers the familiar arguments about how effective demand affects employment. Secondly, the ratio rhoF embodies the macroeconomic price mechanism. It works such that overall employment L INCREASES if the average wage rate W INCREASES relative to average price P and productivity R and vice versa. This is the opposite of what microfounded employment theory teaches.
The correct systemic Phillips curve tells one that in the given situation the most urgent policy measure is to set an increase of the average wage rate in motion. Otherwise, the economy gets trapped in a spiral of rising unemployment and deflation.
