Since 2007, Federal Open Market Committee (FOMC) policymakers have been publishing detailed numerical projections of macroeconomic series over the next 3 years. By testing whether the revisions to these projections are unpredictable, I find that FOMC's efficiency is generally accepted for inflation but often rejected for real economic variables, notably for the unemployment rate. The rejection is due to the strong autocorrelation of revisions, which may reflect information rigidity of FOMC's unemployment projections. The joint efficiency of the entire projection is accepted in most cases.
