One Inflation Number Moved Beliefs Almost as Much as a Fed Statement

A single sentence about the Federal Reserve’s inflation target shifted household forecasts almost as much as an entire policy statement. The finding comes from Olivier Coibion, Yuriy Gorodnichenko and Michael Weber’s study, presented here in its January 2019 working paper version, using a U.S. survey experiment conducted in 2018.
The researchers first measured inflation expectations among Nielsen Homescan panel participants. They randomly assigned respondents to eight information groups or a control group receiving no information. Messages included recent inflation, the Fed’s 2% target, its inflation forecast, a full policy statement and USA Today coverage. Respondents then provided another forecast, with follow-up surveys three and six months later.
Learning the inflation target lowered expected inflation over the next year by about one percentage point relative to the control group. Reading the full statement lowered it by about 1.2 points. The newspaper coverage produced a smaller reduction, around half a point. These were changes in reported expectations; the experiment did not establish a corresponding change in actual inflation.
The comparison group matters because the survey changed its question format: participants initially assigned probabilities to inflation ranges, then supplied a single forecast. Comparing revisions against untreated respondents helped account for changes unrelated to the information. Random assignment supports a causal interpretation of the messages’ effects within this survey.
The effects also faded. The target message still influenced forecasts after three months, but its effect was no longer statistically distinguishable from zero after six. The authors suggested distrust of news media could explain the weaker newspaper response. That remains an interpretation: the articles and official statements differed in wording and content as well as source.
The useful lesson is bounded by the setting: selected household panel respondents receiving information directly during a survey in 2018. A concise benchmark could move reported beliefs substantially, but lasting understanding, spending changes and market responses require separate evidence.
