Endnotes
1. The output gap is defined as the percentage deviation
of actual real GDP from potential real GDP. Potential
GDP is typically estimated as the level of production
consistent with full employment and stable inflation
(see for instance the Congressional Budget Office estimates for the United States).
2. Another source of noise comes from the fact that GDP
values are revised in subsequent months after they
are reported. Although the mean revision is close to
zero on average, revisions can have magnitudes greater than 2% in some quarters. Research has shown that
U.S.
revisions cannot be forecasted with significant
accuracy. See Faust, Rogers, and Wright (2005).
3. Solow (1957) and Jorgenson and Griliches (1967) are
seminal works in the growth-accounting literature.
