Was there a textbook-like Phillips curve in post-WWII Italy? We estimate a consensus model of the relationship between inflation and the level of economic activity over 1949-1998, finding no evidence of a significant and positive feedback from output to prices. We also estimate similar models for the UK and the US. We discuss the role of wage coordination and indexation mechanisms in generating what amounts to a significant departure of Italian data from what holds true for the US and UK. Likely, the rigid indexation mechanism that aimed at protecting wages from inflation ended up contributing to the persistent inflation bias that Italy experienced almost until its entry into EMU.
