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 July 2017 was 3.2% roughly constant
since April, but down significantly from 2016. The unemployment rate fell
significantly during 2017.
The forecasts are summarized in Figure 1 and Table 1. The
point forecast is for the unemployment rate to increase slowly for the next 12
months, rising to 3.8% by July 2018. The 80% forecast intervals show that there
is considerable additional uncertainty. There is a possibility that the
unemployment rate could decrease, possibly as low as 2.7% by December 2017. It
is also possible that the unemployment rate could substantially increase, to 5.0%
by July 2018. The 50% forecast intervals refine this uncertainty, showing that
it is unlikely the unemployment rate will decrease below 3.1% over the next
year, or increase over 4.0% before May 2018. Overall, the forecast is for the
unemployment rate to increase during 2018.
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.
To understand the economic reason behind these forecasts, the
econometric model finds the following salient features. The state unemployment
rate is below its long-term average. Mean reversion predicts an increase of
about 0.60. Similarly, the U.S. national unemployment rate is low, accounting
for an increase of about 0.20 over the upcoming year. The spread of low-grade
corporate bond yields over investment grade is lower than average, accounting
for a predicted decrease of about 0.3.
Housing starts are below their long-term average, accounting for a
predicted decrease of 0.5. Building permits are also below their long-term
average, accounting for an increase of about 0.5 over the upcoming year. The
other variables contribute only small effects to the forecast. Together, most
of these effects offset with the net effect of a modest increase.
