used in all the agency equations are listed in Table
5.2 and the lerms in Table 5.3. Note Ihal the numbers
in parentheses above the terms of Equation III (5.9)
refer to the identification of the terms lisled in Table
5.3; the same is also true of Equations IV and V.

The indepdendent variables of Equation III (5.9)
are included also in Equations IV (5.16) and VI
(5.21) with different coefficients.11 The variables

The r square of Equation III is .662. The signifi-
cance levels of the terms are (I) .0222; (2) .0074; (3)
.0125; (4) .0001; (5) .1277; and (6) .0001. The F test
for the whole equation was higWy significant, beyond
.0001.
