This article attempts to identify precursors, or indicators,
of New England employment. The predictive power of a
diverse array of variables is calculated and compared.
However, because no single variable is likely to contain
all information of predictive value, the article then
explores alternative methods of combining several variables
into an index or statistical "model" of New
England employment growth. The variables are separated
into regional, national, and expectational in order
to measure the predictive value of each type of information.
In both in-sample and out-of-sample tests, a model
that included all categories of variables was the most
successful. However, relative to its in-sample fit,
every model performed poorly out of sample. The reason
for this breakdown is clear--the models were fit during
the "Massachusetts Miracle" while their predictive
power was tested over the New England bust. The lack
of a theoretical model and deficiencies in the available
data make a purely statistical approach to predicting
the New England economy suspect. Some insights can be
gained, however, by surveying the New England economy
in a broader historical context.
