Since both total and federal spending will be examined, it is necessary to designate two independent variables to measure government employment: total government civilian employment(GCE) and federal government civilian employment relative to the total labor force(FGCE).
This may be partly due to the fact that in Table 2 MS has become such a dominant variable that it suppresses the significance of [U.sub.t-2] and FGCE. However, further research is needed to appropriately explain the different performance of these two variables in the two tables.
