where r is the polynomial in the lag operator B resulting from the
solution process* Writing this in a more parsimonious form by dropping
all terms which are small relative to the leading parameters (less than
.1) yields
(5) Wt = (.651 ,203B)Pt + '(B)at
Hereafter, only expressions (1) through (5) are given for the remaining
price relationships.
