The Forecasting Record of the US Model: July 31, 2003
|
|
Data revisions make it difficult to compare forecasted and actual
values. Should the forecasted values be compared to the first release
of the data, the second release, the first major revision release, the
last major revision release, etc.? How should one treat conceptual
changes? Since the first US model forecast analyzed here (September 23,
1983), there have been many revisions of the data in the national income and
product accounts and two major conceptual changes. The first
major conceptual change was the shift in focus from GNP to GDP, and
the second was moving to a chain-type measure of real GDP.
Regarding GNP versus GDP, the model treats the difference between the
two as exogenous, and for forecasting purposes the difference is
taken to be roughly unchanged over time. This means that the forecasted
growth rates of GNP and GDP are essentially the same. One can thus look
at the past forecasts of GNP growth rates
(before the shift in focus) as also forecasts
of GDP growth rates,
and they can thus be compared to the actual GDP growth rates. This
is what is done in the following tables. The actual values for all quarters
are taken to
be the actual GDP growth rates, but the forecast values before the change
in focus are taken to be
GNP growth rates. The same is true for the price index: the
actual values are taken to be the actual growth rates of the
GDP deflator, but the forecast values before the change in
focus are taken to be the growth rates of the GNP deflator.
Regarding the move to a chain-type measure, the following tables use the
new measure. In other words, the model is being judged on how well it
has forecasted the current estimates of the
actual values based on the chain-type
measure. If one thinks of these actual values as being the best current
estimates of what actually happened, then the model is being judged on
how it predicted what actually happened.
This seems to be an interesting comparison, although there is clearly no
right or wrong choice. Other choices could be made.
Beginning in October 1999 and continuing through April 2000 the
NIPA data were revised back to 1929, and the revised data
are used for the actual values
in the tables below. Again, the model is being judged on how well it
has forecasted the current estimates of what actually happened.
Tables 1 through 5 present the forecasting record of the model for real
GDP, the GDP deflator, and the unemployment rate.
The tables are fairly self explanatory,
and only Tables 4 and 5 will be discussed here.
Tables 4 and 5 show how well the model forecasts one year
ahead. Table 4 presents for each forecast the actual and predicted values
of the growth rate of real GDP four quarters ahead, that is, the growth rate
of real GDP over the first four quarters from the beginning of the forecast
period. The results are as follows.
The model did extremely
well in predicting the strong growth in the last half of
1983 and in 1984 and 1985. For example, the growth rate in the
1983:3-1984:2 period was 7.9 percent, and the model
predicted 7.4 percent. The
model overpredicted slightly the period around 1986 (forecasts 10-13),
although the largest error is only 1.5 percentage points.
It was then reasonably accurate until the recession of 1990-1991, which it
missed. As is well known, the recession of 1990-1991 was
hard to predict, and
the model certainly did not predict it. The model did well in
predicting the size of the recovery from the recession (forecasts 32-40).
Forecasts 41-44 underpredicted the growth rate between 0.9 and 1.8
percentage points. Forecasts 45-48 were
fairly accurate. Between forecasts 49 and 65 (July 29, 1995, through
July 30, 1999),
the model underpredicted the growth rate by an average of 1.8
percentage points.
The largest error in this period is for forecast 62 (November 3, 1998),
where the model underpredicted by 3.3 percentage points.
Much of the strong growth between 1995 and 1999 was probably due to the
wealth effect from the stock market boom, and the stock market boom was
not predicted by the model. This is probably the main reason for the
underprediction of the growth rate between 1995 and 1999.
Forecasts 66 and 67 were quite accurate, and
forecasts 68-70 (April 28, 2000, July 31, 2000, and
October 30, 2000) overpredicted
by 2.0, 2.6, and 3.0 percentage points respectively.
Forecasts 71-73 were fairly accurate; forecast 74 underpredicted the
growth rate by 2.7 percentage points, a large error; forecast 75
was fairly accurate; forecast 76 overpredicted by 1.2 percentage
points; and forecast 77 was quite accurate.
The mean absolute error for the 76 forecasts in Table 4 is 1.18 percentage
points.
Table 5 is the same as Table 4 except that it is for the growth rate of
the GDP price index. The mean absolute error for the inflation forecasts is
only 0.59 percentage points, and the largest error in absolute value for any
of the forecasts is only 1.8 percentage points. The inflation forecasts are
thus overall quite good.
Between forecasts 39 and 66 (January 31, 1993, through November 5, 1999)
the error was never larger than .6 percentage points in absolute value.
For forecasts 67-77 (January 29, 2000, April 28, 2000,
July 31, 2000, October 30, 2000, January 31, 2001, April 27, 2001,
July 27, 2001, November 1, 2001, January 31, 2002, April 27, 2002, and
July 31, 2002)
the model overpredicted inflation by .9, 1.2, .8, .9, 1.2, 1.6, 1.6, .7,
.3, .1, and .1 percentage points respectively.
