This memo reports a 12-month forecast for the seasonally
adjusted Wisconsin unemployment rate. In addition to point forecasts (the
expected future value of the unemployment rate), the memo also reports 50% and
80% forecast intervals (probable ranges for future values).
The unemployment rate in August 2012 was 7.5%, increasing
from 7.3% in July, and from the low of 6.7% achieved in April 2012.
The forecasts are summarized in Figure 1 and Table 1. The
point forecast is for the unemployment rate to increase slightly to 7.6% and
stay roughly constant over the next year. The 80% forecast intervals show that
there is considerable additional uncertainty. In particular, there is a
possibility that the unemployment rate could increase to as much as 9.1% by August
2013. There is also a significant probability that the unemployment rate will
continue to fall, as low as 6.3% by August of 2013. The 50% forecast intervals
refine this uncertainty, showing that it is unlikely that the unemployment rate
will rise over 8.3%, and may fall to 6.9% within a year. Overall, the
likelihood of further increases and decreases are roughly comparable.
A 50% forecast interval is designed to contain the future
unemployment rate with 50% probability. It is just as likely for the rate to
fall in this interval as out of it. This is the smallest possible interval
which has even odds of containing the future rate. We can think of this
interval as “likely” to contain the future rate.
An 80% forecast interval is designed to contain the future
unemployment rate with 80% probability. We can think of this interval as
“highly likely” to contain the future rate. The 80% interval is designed so
that there is a 10% chance that the future value will be smaller than the
forecast interval, and a 10% chance that the future value will be larger than
the forecast interval.
