We develop this measure using assumptions common in economic analysis of open economies. Using quarterly data from 9 OECD countries and the simplest econometric specification, we estimate the Phillips curve with the same functional form for the 1970s, 1980s, and 1990s. Our analysis suggests that although changing expectations played a role in creating the empirical failure of the Phillips Curve in the 1970s, supply shocks were at least as important. ER -
