As noted in the text, further innovations, including interest rate projections and long-run projections of economic growth, unemployment, inflation, and the federal funds rate were added over time. The role of the projections in policy communication was also significantly increased after October 2007; for example, they were regularly referenced in the Chairman’s semiannual Humphrey-Hawkins testimony before the Congress (see Board of Governors, 2007a, 2007b).
I can make this point more vividly by contrasting the Australian position with that of the United States, where there is a renewed interest in the "trade cycle" analysis which, in the immediate post-WWII decades, dominated short-term economic commentary.
