MDG−, mostly occurring in developing regions, are due to the increased
labor partici pation assumed above.
One notable interaction is the competing effect of per capita GDP and
popu lation—or, equivalently, of the assumed negative correlation between
labor productivity and labor force—across the scenarios. Thus, in all regions,
the variation of the total GDP between the scenarios (absent of POP6/MDG−)
is much less than the variation of per capita GDP. We suppose that the above
variation in per capita GDP between the scenarios is large enough as even
a slightly larger variation would result in much less variation in total GDP,
which would not be useful to explore a potential ...
