This paper documents the evolution of long-run inflation expectations and models the stance of monetary policy from 1965 to 1980. A host of survey-based measures and financial market data indicate that long-run inflation expectations rose markedly from 1965 to 1969, leveled off in the mid-1970s, and then rose at an alarming pace from 1977 to 1980. While previous studies have shown that the trajectory of the federal funds rate over that period is not well-represented by a Taylor rule with a constant inflation goal, our analysis indicates that the path of policy can be characterized by a reaction function with two breaks in the intercept—in 1970 and 1976—that correspond to discrete shifts in an implicit inflation goal. This reaction function ...
